JavaScript - Using Combo Box To Create Second Combo Box And Add Second Selection To Session
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 Similar TutorialsHello 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 Hi guys, I need your help in this... I try to reuse double combo boz with description in http://www.javascriptkit.com/script/...ombotext.shtml... I need to make it load content from external div instead of text in array as description. This is because there are so many selection and some can refer to the same description. I already changed the description so it can read html tag. But I have no idea how to put div id inside array and load the div content. Anyone can help me solve this? Really appreciate your help 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.
Hi I am doing a java program. In which I have a jsp page, and on that I have two combobox. I have a create a java bean, in which I am extracting the database. I want to populate the combobox by extracting data from database. can anyone suggest me some code using java script , which i can use to populate my combobox. Thanks in advance I was wondering if I could get some help in something. I am working on my church's website, and I previously implemented something called "Reftagger" onto the new website: http://www.logos.com/reftagger It "converts" any bible verse into a hyperlink as well as a tooltip. I thought that this was a neat idea, and wanted to do the same with the Westminster Larger (and Shorter) Catechism as well. Anytime it says "WLC Q58" (for example) I want it to automatically display that specific question and answer. So far, I simply have a basic tooltip and a hyperlink inserted for every WLC Q: http://covenantrpc.freehostia.com/covenant/sermons/ (just look at the page source and you'll see what I did). Then I have the tooltip.js file: http://covenantrpc.freehostia.com/co...ons/tooltip.js What I want to do is create some sort of definition library or glossary. One where it tells the webpage that every time the webpage says "WLC 58" it will be automatically converted into a hyperlink and tooltip, just like Reftagger. On a friend's site I am using a combination of easyslider (a slideshow script) and lytebox (probably doesn't need an intro). It can be seen in action on http://www.maisonportier.com/menu.php (then click on 'Press'). I really don't know much about Javascript so am just able to do extremely simple things such as combining two script. Now my friend want the slideshow to pause when an image is opened (using Lytebox), and to continue when the image is closed. The scripts can be found at: http://www.maisonportier.com/js/lytebox.js and http://www.maisonportier.comeasySlider1.5.js Can anybody tell me how to modify the code? Any help is greatly appreciated! Hi, 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 Hello all, I have a form which contains some fields like company_name, address, phone, email etc. Also, I have a database with companies. 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>

Good day, I'm populating a combo box and I'm working to onchange the url of a div.based on the value selected. Here is my code : PHP Code: <?PHP $console = $_GET['console']; $dir = "Names/"; echo "<select name=\"console\" onchange=\"load('console_info.php?console=<SCRIPT language=\"javascript\">document.write(this.options[this.selectedIndex].value)</script>','page')\" onmouseclick=\"this.focus()\">"; // Open a known directory, and proceed to read its contents $dir_handle = @opendir($dir) or die("Unable to open $dir"); $files = array(); while($file = readdir($dir_handle)) { if($file != '.' and $file != '..') { $files[] = $file; } } sort($files); foreach($files as $file) { if($file != $console) { echo "<option value='$dir/$file'>$file</option>\n"; }else{ echo "<option value=\"$dir/$file\" selected=\"selected\">$file</option>\n"; } } echo "</select>"; ?> I already have a script which make me able to change the url of a div with ajax, this works well. 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. Thanks! 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()

Hi, I am a small problem with the combo boxes in my web page.I have created a web search portal for travelling in that i have used combo boxes for selecting the no.of.passengers (Adults, Childs & Infants) along with the ages of the children.Take for example i have a hotel search page in that i have used combo box to select the no.of.rooms. And i have kept the same concept in selection of passengers too(i.e., when u select Room count as '2' there will two rows displayed separately for choosing adults & child) and when u choose child as '1' another combo box will appear to select for 1 child this is unique for each rooms. Now i can able to do the first part clearly that is when select room count the rows are displaying as per the no. But when i select for child the age combo box is coming same for all the rooms and not as unique (separate) for each room. Can anyone help me to fix this problem! Thanks, |
