JavaScript - 2 Level Combo Box Output Text Same Page
Hello,
I have a 2 level combo box that are dependent on each other and what I want to happen when the "submit" button is selected is for an html text answer to be displayed on the same page below the combo boxes based off of what was selected in the second combo box. I've tried using hide/show functions with JavaScript but couldn't figure out how to link the 2 scripts together. What I have is as follows: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd">

If someone can either assist with this or point me in the right direction of how to do this it would be a great help. Thanks in advance, Similar TutorialsHi, i have a form that uses POST but the post url also has some parameters with it. But i want the parameters to changing depending on a few combo boxes on the page. So what i want to happen is when the combo box is changed it sets a variable and that variable is some how used in the URL link within the HTML. Ive tried writing a function that gets the text of the combo as it changes by alert me with a popup. But when i try to use document.write to add my var in HTML it simple wont show. Am i doing this all wrong? Thanks andy i'm desperately seeking some javascript advice. I'm currently using wysiwyg webbuilder 8. I have one of my combo boxes linking to another but i want the first box to affect text on the page the text id is text23 and here is the coding i am using at the moment Code: <script type="text/javascript">
function fillSecondCombo()

this is the only thing i need to complete the site i am working on Hello I'm using the combo box selection menu by Elviro Mirko from this site (http://www.javascriptkit.com/script/...plecombo.shtml) I have made amendments to show my own data, however what I would like to happen is if the user selects from the top combo only, then all the records would be shown, whereas selecting from the second combo merely 'drills down' and shows the records required. - Hope that makes sense. The code is as follows: Code: // first combo box
data_1 = new Option("Douglas - DIS", "$");
data_2 = new Option("Douglas - COE", "$$");
data_3 = new Option("Peel - DIS", "$$$");
data_4 = new Option("Peel - COE", "$$$$");
data_5 = new Option("Ramsey - DIS", "$$$$$");
data_6 = new Option("Ramsey - COE", "$$$$$$");
data_7 = new Option("Castletown - DIS", "$$$$$$$");
data_8 = new Option("Castletown - COE", "$$$$$$$$");
// second combo box
data_1_1 = new Option("Registry Office Douglas", "-");
data_1_2 = new Option("Broadway Baptist Church Douglas", "-");
data_1_3 = new Option("Finch Hill Congregational Church Douglas", "-");
data_2_1 = new Option("St Thomas's Church", "--");
data_2_2 = new Option("St Barnabas Church", "--");
data_2_3 = new Option("St George's Church", "--");
The HTML code is as follows: Code: <select name="combo0" id="combo_0" onChange="change(this);" style="width:200px;"> <option value="">Select a Register...</option> <option value="Douglas - DIS">Douglas - DIS</option> <option value="Douglas - COE">Douglas - COE</option> <option value="Peel - DIS">Peel - DIS</option> <option value="Peel - COE">Peel - COE</option> <option value="Ramsey - DIS">Ramsey - DIS</option> <option value="Ramsey - COE">Ramsey - COE</option> <option value="Castletown - DIS">Castletown - DIS</option> <option value="Castletown - COE">Castletown - COE</option> </select> <BR><BR> <select name="combo1" id="combo_1" onChange="change(this)" style="width:200px;"> <option value="">Select a venue...</option> </select> the link for the actual site is http://www.manxbmd.com/cgi-bin/db.cg...m;db=marriages If you choose Douglas-COE and search, then 0 records are found, if you choose Douglas-COE followed by St Thomas's then still 0 records are found but if you search the surname Allitson you'll see that there is a record there. I'm not sure where I've gone wrong - I'm completely new to Javascript. Any suggestions welcomed. regards Pendle As of right now I have a code that will work in IE but wont work in FireFox...go figure. Basically what I want to have happen is when you type in an area code it will provide an output in a predetermined area of the page. For Example: Input- 512 Output - Austin, TX The code that I have doesn't work with firefox and I was just wondering if there was a code that would allow that to happen. Thanks! Hi Everybody This is probably a very commonly asked question, however after much searching online I can't seem to find a straightforward answer. If anyone knows the code or a link to a place with a simple example it would be great. What I have got is a form that a user has to fill out and submit (when validated all variables are stored in a session and emailed after multiple forms are completed), currently I have radio buttons, text boxes and a combo box/ drop down list (for location). All parts are working fine and validating fine. My problem is to do with the combo box//ddl. I have successfully validated the ddl so the user must select a location onsubmit and it is added to session and passed fine. At the moment the ddl only has cities or towns in it however as I would like to include different states and possibly different countries I need a code that validates the state first and then only gives the cities/towns that are in that state (otherwise my ddl would be to large). I can do this with links however I can't seem to do it in a form. I am trying to do it this way DDL has list of all states that on mouseover/ onclick the list is revealed. onclick of a specific state populates another ddl with only the cities cities/ towns that are in that state and onclick of specific city selects the location whereby onsubmit the location is stored in the the session for submission by email Thanks in advance for your help I still have the following two major issues. 1) Firstly I need to be able to send the selection from the second combo box by php. 2) secondly I need the combo box to appear within the table. (I thought this should be easy, but for the life of me cannot figure out how to get the dynamic combo into my table inside the form) I have managed to send the selection from the first combo box with the form and also I can send a selection from the second combo, however onsubmit regardless of what is selected in the second combo box it simply sends the last option not the one selected. I have spent many hours trying to figure out why this is the case to no avail. I have included my code for anyone who may be able to help. Lastly when I have figured out these 2 (with a little help) I should be able to sort out the validation by myself. Please ignore any code that is not relevant <html> <head> <script type="text/javascript"> var this1; window.onload = function() { if (!document.all) document.captureEvents(Event.CHANGE); document.getElementById('myddl').onchange = readDDL1; } function readDDL1() { var ddlobj = document.getElementById('myddl'); var currentSelection = ddlobj.options[ddlobj.options.selectedIndex].value; if (currentSelection == '') currentSelection = ddlobj.options[ddlobj.options.selectedIndex].text; doDDL2(currentSelection); } function doDDL2(ddl1Selection) { var existingDDL2; if ((existingDDL2 = document.getElementById('myddl2')) != null) existingDDL2.parentNode.removeChild(existingDDL2); var ddl2Options; switch (ddl1Selection) { case "Western Australia": ddl2Options = ["Please Select A Location", "Karratha", "Perth"]; break; case "Queensland": ddl2Options = ["Please Select A Location", "Brisbane", "Gold Coast"]; break; } if (typeof ddl2Options == "object") { ddl2 = document.createElement('select'); ddl2.id = "myddl2"; var forVar; for (forVar in ddl2Options) { var newOption = document.createElement('option'); newOption.appendChild(document.createTextNode(ddl2Options[forVar])); ddl2.appendChild(newOption); } document.body.appendChild(ddl2); } document.testform.this1.value = ((ddl2Options[forVar])); } function checkFrequency() { return ShowResults(); } function validate(){ var digits="0123456789" var temp if (document.testform.location.selectedIndex == 0) { alert("Please Select a State"); return false } if (document.testform.location2.selectedIndex == 0) { alert("Please Select a Location"); return false } return true } </script> <style type="text/css"> .td_freq { background-color:yellow; height:40px; text-align:center; } .td_sev { background-colorink; height:40px; text-align:center; } .td_wi { background-color:lightgreen; height:40px; text-align:center; } </style> </head> <body> <FORM name="testform" action='./emlapd.php' method='post' onsubmit="return checkFrequency()"> <input type='hidden' name='this1'> <table align="center" border="1" width="40%"> <tr><td><b>Current Worksite State:</b><font color="red">*</font></td> <td> <select name="location" width='53' id="myddl"> <option value="0">--- Please Select Your State --- & nbs p; & n bsp; & nbs p; </option> <option value="Western Australia">Western Australia</option> <option value="Queensland">Queensland</option> </select> </td></tr> <tr><td><b>Location:</b><font color="red">*</font></td> <td> </td></tr> </table> <tr> <th colspan="2"> <input type="submit" name='submit' value="Submit" onclick= "return validate()"> </th> <td colspan="10"> </td> <th> <input type='reset' name='reset' value='Clear Form'> </th> </tr> </table> </FORM> </body> </html> Thankyou very much to everyone that may help So I can place the DDL inside the form, however it places it at the end of the form. I want it somewhere in the middle (immediately following first combo box) My other main issue is irregardless of the selection it simply posts the last option from the DDL not the one selected. Therefore I still want the second combo box to appear immediately below the first combo box and whatever option is selected from the second combo box I want to be posted with the rest of the form data. If you have any other ideas that would be great Obviously the reason I am still getting the same incorrect post is because the variable posted is still this1 from my code which reads the last value from the DDL. I have tried with all other variables to send as well ie ddl2 however still can't seem to send the selection. So in its current state how can I send the selection and place the second DDL within the form?? Thank you hey I have a page in which I already have a 3 level combox that works fine. I want to add to that page another combobox of 2 level. When I tried to do it I find out that they control of each other. I tried changing the variables names. (changing "x" into "w" in the second combobox) Well that worked. Can you please help me figure it out? here is the end of the first form: var temp1=document.isc.stage3 function redirect1(y){ for (m=temp1.options.length-1;m>0;m--) temp1.options[m]=null for (i=0;i<secondGroup[document.isc.example.options.selectedIndex][y].length;i++){ temp1.options[i]=new Option(secondGroup[document.isc.example.options.selectedIndex][y][i].text,secondGroup[document.isc.example.options.selectedIndex][y][i].value) } temp1.options[0].selected=true } function redirect2(z){ parent.mainframe.location=temp1[z].value; and here is the end of the second combobox: var temp=document.doublecombo.stage2A function redirect(w){ for (n=temp.options.length-1;n>0;n--) temp.options[n]=null for (k=0;k<groupa[w].length;k++){ temp.options[k]=new Option(groupa[w][k].text,groupa[w][k].value) } temp.options[0].selected=true } function go(){ location=temp.options[temp.selectedIndex1].value } Thanks Elad my password target opens in a new window using the 'open.window' command but i would like a command string that opens this target in the same frame within my frames page that my other pages open in. thanks in advance manj Hello everyone I am trying to receive the output of an array from a text input here is the code that I am attempting to do but it is not displaying the output January Here is the code example [CODE] <html> <script type ="text/javascript"> <!-- function coms(str){ var myArray = new Array(); myArray[0] = ["January"]; var index = 0; for(var i = 0; i < myArray.length; i++){ index; if(myArray[i] == "January"){ index i; } if(str.length == myArray[i]){ document.write(str); } } } </script> <body> <form> Panel:<input type="text" name="panel" onkeyup="coms(this.value)" /> <div id="read"><p>Data is displayed here</p></div> </form> </body> </html> [CODE] Any tips to make this possible are welcome thank you kindly Hello, I use a iplocator api, which is javascript and gives out the city name, country and zipcode output PHP Code: <script language="JavaScript" src="http://www.somesite.com/somefile.js?key=apikey"></script> <script language="JavaScript"> <!-- document.write(ip2location_isp() + ', ' + ip2location_city() + ', ' + ip2location_zip_code() + ', ' + ip2location_net_speed()); //--> </script> my question or where i need help is that, i would like to output each of those as a hidden text field, so later i can store into mysq database with POST method from the hidden field. thank you in advance for your time n help Hi Guys, I want to output my pagetitle in javascript.

Right down the bottom, under the word 'Quote is where the output should go. Any suggestions on how to do this? Regards Jenny Hi all, Thanks for reading. I'm having an issue trying to accomplish the following - I have a text field (field1) already displayed on the HTML page. However, there's a link where you can add additional text fields to the page as well. When the link is clicked, the second text field is added successfully (field2), and when the link is clicked again, the third text field (field3) is added successfully. However, the third field does not add itself to the page, and the text for anything greater than a third field also isn't displayed after. This obviously means that my "fields" variable is not working right, so I'm wondering, would anyone be able to assist me to help me get that variable processing correctly? Code: <script language="javascript">
fields = 1;
function addMore() {
if (fields = 1) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field2' size='25' /> <span>Field 2.</span>";
fields = 2;
} else if (fields = 2) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field3' size='25' /> <span>Field 3.</span>";
fields = 3;
} else {
document.getElementById('addedMore').innerHTML = "Only 3 fields are allowed.";
document.form.add.disabled=true;
}
}
</script>
Here is the code in my HTML - Code: <input type="text" name="field1" size="25" /> <span>Field 1.</span> <div id="addedMore"></div> <p class="addMore"><form name="add"><a onclick="addMore()">Add another field.</a></form></p> Thank you very much. Hello, I am very new to HTML and PHP but have managed to create a drop down "Surname" box on my website to list all the current surnames in my mySQL database. However, I also want the user to be able to type into the box and for the drop down list to automatically filter depending on the text the user inserts. I understand that this is not possible in HTML and PHP and requires some JavaScript, however I have never used this before and have no idea where to start. Any suggestions or help will be much appreciated. Here is my current HTML and PHP code... Code: $sql="SELECT Surname FROM Patients";
$result=mysql_query($sql);
?>
<form name="form" method="POST" action="<?php echo $_SERVER['PHP_SELF'];?>">
Surname: <?php echo "<select name=\"surname\">"; echo "<option size =30 ></option>";
while($row = mysql_fetch_array($result))
{
echo "<option value='".$row['Surname']."'>".$row['Surname']."</option>";
}
echo "</select>";
?>
Thank you! I have 2 combo boxes where you can move the items in combo box 1 to combo box 2. I want to validate that combo box 2 actually has something moved to it. How can I count the items in combo box 2. Combo box 2 will initially have no items in the box on page load. It is up to the user to move the items to combo box 2 and I want to make sure at least 1 item was moved.

Here is the code which do that: PHP Code: <script type="text/javascript"> function ahah(url, target) { document.getElementById(target).innerHTML = ' Fetching data...'; if (window.XMLHttpRequest) { req = new XMLHttpRequest(); } else if (window.ActiveXObject) { req = new ActiveXObject("Microsoft.XMLHTTP"); } if (req != undefined) { req.onreadystatechange = function() {ahahDone(url, target);}; req.open("GET", url, true); req.send(""); } } function ahahDone(url, target) { if (req.readyState == 4) { // only if req is "loaded" if (req.status == 200) { // only if "OK" document.getElementById(target).innerHTML = req.responseText; } else { document.getElementById(target).innerHTML=" Error:\n"+ req.status + "\n" +req.statusText; } } } function load(name, div) { ahah(name,div); return false; } </script> onchange="load('console_info.php?console?=','page')" The part I have problem with is the part when the combo box get changed with an onchange, I don't know how to add after the console?= as the user change the option . example: PHP Code: <SCRIPT language="javascript\">document.write(this.options[this.selectedIndex].value)</script> But if I do this, since i'm using php to write this it only write that. I don't know how can i make this work.

Select City- (Like - New Delhi , Mumbai ,Kolkata ,Chennai) 2. Select Cinema(Hall Name) - ( Saket - New Delhi , South Ex. - New Delhi, Navi Mumbai - Mumbai , Salt Lake - Kolkata) 3. Select Movie- (Atleast 3 movies in each cinema nd somtimes it can more or less hall by hall ) 4.Select Date - (next 5 days of current date for advanced booking) 5.

I want that, when typing the beginning of the company name, a combo box to suggest all companies that match that text. I want that when a company is selected from the combo, all other textboxes to be filled with the correct info from the database. Also, I want that the user to be able to write a company that is not registered in the database. What I have done until now: For the editable combo I used the dhtmlxcombo from he http://dhtmlx.com/docs/products/dhtmlxCombo/ (Filtering mode: (filter existing list)). I'm not a scripting expert, so I think I cannot build this combo all by myself. I modified just one thing. At the begining, the dhtmlxcombo.js file contained something like this: Code: if (tab)z.tabIndex=tab;z.style.width = (width-19)+'px';self.DOMelem.appendChild(z);self.DOMelem_input = z;z = document.createElement('input');z.type = 'hidden';z.name = name;self.DOMelem.appendChild(z);self.DOMelem_hidden_input = z;z = document.createElement('input');z.type = 'hidden';z.name = (name||"").replace(/(\]?)$/, "_new_value$1");z.value="true";self.DOMelem.appendChild(z);self.DOMelem_hidden_input2 = z
I added z.id='dest_company';, so the file looks something like this, now: Code: if (tab)z.tabIndex=tab;z.style.width = (width-19)+'px';self.DOMelem.appendChild(z);z.id='dest_company';self.DOMelem_input = z;z = document.createElement('input');z.type = 'hidden';z.name = name;self.DOMelem.appendChild(z);self.DOMelem_hidden_input = z;z = document.createElement('input');z.type = 'hidden';z.name = (name||"").replace(/(\]?)$/, "_new_value$1");z.value="true";self.DOMelem.appendChild(z);self.DOMelem_hidden_input2 = z};dhtmlXCombo_defaultOption.prototype._DrawHeaderButton = function(self, name, width)
The text field 'dest_company' is generated like this: PHP Code: <select name="dest_company" id="dest_company" OnChange="SelectReceiver(document.comanda.dest_company.value);" style="width:206px;" tabindex="10"> <?php echo ' <option value=""></option>'; $address_result = mysql_query("SELECT * FROM `webdb_".$_COOKIE['user']."` ORDER BY companie ASC"); while($row = mysql_fetch_array($address_result)) { echo '<option value="'.$row['id'].'">'.$row["companie"].'</option>'; } echo ' </select> <script> var z = dhtmlXComboFromSelect("dest_company"); z.enableFilteringMode(true); </script>'; ?> This is the SelectReceiver() function: Code: function SelectReceiver(id_dest)
{
if (id_dest=="")
{
document.getElementById("contact_destinatar").value="";
document.getElementById("adresa_destinatar").value="";
document.getElementById("oras_destinatar").value="";
document.getElementById("judet_destinatar").value="";
document.getElementById("zip_destinatar").value="";
document.getElementById("telefon_destinatar").value="";
document.getElementById("mail_destinatar").value="";
return;
}
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
//document.getElementById("detalii_destinatar").innerHTML=xmlhttp.responseText;
var response = eval(xmlhttp.responseText);
}
}
xmlhttp.open("GET","modifica_detalii_destinatar.php?q="+id_dest,true);
xmlhttp.send();
}
And the file modifica_detalii_destinatar.php looks like this: PHP Code: <?php $q=$_GET["q"]; include ('conectare.php'); $sql="SELECT * FROM `webdb_".$_COOKIE['user']."` WHERE id='".$q."'"; $result = mysql_query($sql); while($row = mysql_fetch_array($result)) { echo ' document.getElementById("contact_destinatar").value = "'.$row['contact'].'"; document.getElementById("adresa_destinatar").value = "'.$row['adresa'].'"; document.getElementById("oras_destinatar").value = "'.$row['oras'].'"; document.getElementById("judet_destinatar").value = "'.$row['judet'].'"; document.getElementById("zip_destinatar").value = "'.$row['zip'].'"; document.getElementById("telefon_destinatar").value = "'.$row['telefon'].'"; document.getElementById("mail_destinatar").value = "'.$row['mail'].'"; '; } ?> All this is working just in Firefox. In IE, when I select a company from the combo box, an error is generated and no text box is completed with the correct data. The error I'm talking about is: Code: 'document.comanda.compania_destinatar.value' is null or not an object In Firefox, if I inspect element with Firebug, my select looks like this: Code: <div style="width: 204px;" class="dhx_combo_box ">
<input type="text" autocomplete="off" class="dhx_combo_input" tabindex="10" style="width: 185px;" id="companie_dest">
<input type="hidden" name="dest_company" value="45">
<input type="hidden" name="dest_company" value="false">
<img class="dhx_combo_img" src="codebase_xcombo/imgs/combo_select.gif">
</div>
Any help on this would be great. Many thanks and best regards! Hi all, I have a form which takes some values as input and stores them in a db for another use. I have the following java script to validate the entries. Code: <HTML><HEAD><TITLE>Electronic Deposting Form</TITLE>
<script language="JavaScript">
<!-- script start
function validateComplete(formObj) {
if (emptyField(formObj.username))
alert("Please enter the Username.");
else if (emptyField(formObj.passwd))
alert("Please enter the Password.");
else if (emptyField(formObj.drop))
alert("Please enter the Drop Folder.");
else return true;
return false;
}
// Check to see if field is empty
function emptyField(textObj)
{
if (textObj.value.length == 0) return true;
for (var i=0; i<textObj.value.length; ++i) {
var ch = textObj.value.charAt(i);
if (ch != ' ' && ch != '\t') return false;
}
return true;
}
function chklen() {
var un = document.getElementById("username").value
var len = un.length;
if (len > 15) {
alert ("ERROR!!Only 15 characters are allowed in Username!!");
document.getElementById("username").value = un.substring(0,15); // remove excess characters
}
}
// script end -->
</script>
Now I am planning to add a combo box to the form where I have the environment field. Following is the code for the form. Code: <td align="left" valign="top"><FORM name="form" action="../saveDP.cgi" method="post" onSubmit="return validateComplete(document.form)"><TABLE width="100%" cellPadding=2 cellSpacing=2>
<TR>
<TD width="26%" class="label"><B>Username </B></TD>
<TD width="3%" class="label">:</TD>
<TD width="71%"><INPUT maxLength=255 size=28 name=username id='username' onkeyup="chklen()">
<TR>
<TD class="label" ><B>Password </B></TD>
<TD class="label">:</TD>
<TD><INPUT type=password maxLength=255 size=28 name=passwd>
<TR>
<TD class="label"><B> Environment </B></TD>
<TD class="label">:</TD>
<TD><SELECT class="input" size=1 name=environ>
<OPTION value=us selected><b> US </b></OPTION>
<OPTION value=uk><b> UK </b></OPTION>
</SELECT> </TD>
</TR>
<TD colspan="3"><table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="19%"> </td>
<td width="9%"><INPUT type=submit value=Submit v:shapes="_x0000_s1034"> </td>
<td width="8%"><input type=reset value=Clear v:shapes="_x0000_s1035\"></td>
<td width="64%"> </td>
</tr>
</table></TD>
</TR>
As I am new to JS, can anybody help me to implement a combo box( ie first two options are US and UK and third one is a text box which i can enter any value, can't be left blank while submitting the form) with "Environment" field? |
