JavaScript - Onchange With Submit
hi
i have a form where i need to join fields from the form prior to submission to flow into a pdf form. here is the function PHP Code: <SCRIPT language='javascript' type='text/javascript'> function joinna(form, elemName, ttl) { form.bname.value = form.b_fname.value + ' ' + form.b_lname.value; } </script> here is what the form input looks like PHP Code: <input class="left" onBlur="mark(this,'#ffffff','#000000')" name="b_fname" size="20" maxlength="40" onFocus="nextfield ='cb_fname'; mark(this,'#FFFF99','#0000FF')" value="<?php echo $row['b_fname'];?>" onChange="joinna(this.form,'b_fname','p1f6');"> </span> <input class="left" onBlur="mark(this,'#ffffff','#000000')" name="b_lname" size="20" maxlength="40" onFocus="nextfield ='cb_fname'; mark(this,'#FFFF99','#0000FF')" value="<?php echo $row['b_lname'];?>" onChange="joinna(this.form,'b_lname','p1f6');"> </span> and here is the calc field PHP Code: <input type="hidden" NAME="bname" value="" Size="7" onBlur="mark(this,'#ffffff','#000000')" onFocus="blur();document.smartform.bname.focus()" onChange="this.form.b_fname.value + this.form.b_lname.value; joinna(this.form,'field');" > this works fine IF i manually insert something new into the b_fname field. but lets say a user pulls the for to edit, and then makes no changes, "bname" will remain blank. what i want to do is call the function and/or force an 'onchange' or do whatever so bname is not left blank in the event the user submits w/o making any changes to the form tia Similar TutorialsI have a form with onchange events set on some of the text fields so that calculations can be made. By clicking the Submit button, the form data is then saved to the database. This all works fine as long as you leave a text field by tabbing to or clicking in another field before clicking Submit. However if you make a change in a text field and then directly click the Submit button, the onchange event occurs but the form submission does not. I have tried other types of events such as onfocus, onblur, etc. in place of onchange. I have also tried using the setTimeout function, with various time values, to cause a delay between the onchange and submit events. But the results are the same. Any advice would be appreciated. Thanks.
Hi, I have a form that when you click submit gives a warning box asking if to continue code below Now when I type in the text field and press enter it doesn't submit nor does it pop up the warning box, how would I do this Code for submit button Code: <script LANGUAGE="JavaScript">
<!--
function submitMyForm()
{
var agree=confirm("ARE YOU SURE ?");
if (agree)
return true ;
else
return false ;
}
// -->
</script>
Code: <form action="admin-delete.php" method="post" name="cp_delete" id="cp_delete"> <input type="text" name="cp_delete_bg" id="cp_delete_bg"> <input type="submit" name="submit" value="submit" onclick="return submitMyForm()"/> </form> I've got the following 2 fields in my form: <input type="file" name="filename" id="filename" value="filename"> <input type="submit" name="submit" value="Upload Image" /> Now I want to hide both of them as soon as the submit button is pressed. Problem is that I'm a javascript noob and I can't find it with google :S Can someone help me? Hi all Is using the real form submit button a problem in any way? Can it actaully send a form when a person uses 'enter' in a text field. When I use this submit, it triggers my validation which is great. Code: <input type="submit" value="OnSubmit validate" /> However this way doesn't seem to trigger my validation although It may solve the above form send problem (if that realy exists). How do I get it to act the same as real submit so it will trigger validation like onsubmit above? Code: <input type="button" value="Send Feedback" onclick="this.form.submit()" /> LT does any of that make sense? all ideas helpful and appreciated I have created some online software which uses form data to submit to another page. The problem is that I have other submit buttons in the same form which submit to different pages (depending on which button is pressed). The first submit button works fine but all the others only work once. Code: <input class="cssbutton" type='submit' value='Button1' onclick="wbform.action='page1.php'; target='mainFrame'; return true;"> <input class="cssbutton" type='submit' value='Button2' onclick="wbform.action='page2.php'; target='_blank'; return true;"> <input class="cssbutton" type='submit' value='Button3' onclick="wbform.action='page3.php'; target='topFrame'; return true;"> <input class="cssbutton" type='submit' value='Button4' onclick="wbform.action='page4.php'; target='topFrame'; return true;"> <input class="cssbutton" type='submit' value='Button5' onclick="wbform.action='page5.php'; target='_blank'; return true;"> <input class="cssbutton" type='submit' value='Button6' onclick="wbform.action='page6.php'; target='_blank'; return true;"> Any ideas my friends? Hi folks. I'm working on a calculator and need to use the 'onchange' function. Basically, the user selects the year (id=taxYear) and once the year is select (default is 2008) this year will appear in 2 different lines of the page under 2 seperate ID's(ageYear & totalYear). I've looked at a few example of the function but I'm still not sure how to approach it. At the moment the year changes once I hit the 'calculate' button but the onChange would obviously offer a better alternative with the date changing once 'taxYear' is changed. here is the script; Code: //check the year
var taxYear = document.getElementById('taxYear').options[document.getElementById('taxYear').selectedIndex].value;
document.getElementById('ageYear').innerHTML = taxYear;
document.getElementById('totalYear').innerHTML = taxYear;
Here is the jsp; Code: <tr>
<td align="left" width="203" colspan=""><p> Your Tax Year: </p></td>
<td align="left" >
<s:select name="taxYear" id="taxYear" list="#{'2008':'2008', '2009':'2009'}" theme="simple" />*
</td>
</tr>
<tr>
<td align="left" width="203"><p> Age at December 31st <span id="ageYear"></span></p></td>
<td align="left" colspan="1">
<s:textfield name="age" id="age" theme="simple" cssClass="text" value="30" /> *
<div id="errorage" class="warningmessage" style="display:none">
Please enter your Age to proceed.
</div>
</td>
</tr>
<tr>
<td colspan="2" class="basicboldtext">
<br/>
The total pension contribution you can make for year <span id="totalYear"></span> is €<span id="totalTax2"></span>
<br/>
</td>
</tr>
Appreciate any help on this! Code: <input type = "text" style ='display:none;' onchange="display_data_from_server(this.value)"/> Value inside that input is cahanged from js. Is there any reason that onchange would not happen ? i mean, it does not. I have a onChange value
Code:
var people = [
["Timothy Conner", "1999-Present", "Age: 12", "Male", ""],
["Andrew Conner", "1992-Present", "Age: 19", "Male", ""]
];
var how = "Brothers";
function find()
{
if(document.getElementById("name").value == people [0] [0])
{
document.getElementById("desc").value = people [0] [1] + " " + people [0] [2] + " " + people [0] [3];
}
if(document.getElementById("name").value == people [1] [0])
{
document.getElementById("desc").value = people [1] [1] + " " + people [1] [2] + " " + people [1] [3];
}
document.getElementById("relateb").value = document.getElementById("name").value;
}
Code: Name: <input type="text" id="name" value="" onChange="find()"/> So for it to proses a name you must click out of a box is ther a way to make it instead of when you click out of it, it would immidiatly change? Hi all, I'm designing something to addon to an existing product. I'm struggling with some javascript problems. I want to submit a hidden field when you click on an image button, rather than it being an actual submit button. It's going to submit the value "1" to a PHP page, but I don't want it to actually have to GO to the PHP page, just submit it within the webpage. Is this possible? Thanks I am trying to auto submit a login form remotely using .submit() . It's submitting, but for some reason if I use submit() the login isn't processing. However, if I turn off the auto submit and use an actual submit button it logs in just fine. Now, in the form tag there is a call onsubmit for some validation, does .submit() trigger that form onsubmit="" function? Is there something that happens differently when a user clicks a button verses the .submit(). Thanks! Paul I have an onchange event JS working fine in IE, but not in FF. It's intended to reset an input field to zero when an adjacent drop-down menu value is changed. I've spent a half-hour looking for answers, and nothing has worked. Decided to post here in the hope there is a quick solution I've overlooked. TIA. Code: function resetInput()
{
y = document.getElementById("baseInput");
y.setAttribute("value","0");
}
And the HTML... Code:
<select id="baseMethod" onchange="resetInput()">
<option value="baseGrowth" selected="selected">Annual Growth Rate (%)</option>
<option value="baseTarget">Target Year Projection</option>
</select>
<input type="text" name="baseInput" id="baseInput" value="0" size="14" maxlength="14" /><br />
i keep getting the following error: - there is no attribute "onChange" Code: <select name="type" id="type" onChange="gettype('type');">
<option selected="selected">--Car type--</option>
<option value="1">Bmw</option>
<option value="2">Merc Blinds</option>
<option value="3">Ford</option>
<option value="4">Saab</option>
</select>

Evening all. I have a little bit of code, thus: Code: var data = document.createElement("td");
box = document.createElement("input");
box.id = headercategories[i];
box.type = text;
box.value = "Ten";
box.onChange = alter("11");
data.appendChild(box);
in which I insert a text input box into a table data element. When the value of the input is changed, I would like to call the function alter(). However, what's happening in practice is that the function alter is getting called straight away, without waiting for any changes. Is there any way I can stop this? It doesn't seem to happen if you actually write the onchange bit into the HTML by hand rather than doing it dynamically. Thanks, Chris Hello all, I have a translation script that I want to modify to use select boxes instead of divs, but I have a little problem with what I have. Bascially, the user selects an option and it changes the text in between the ' ' (VALUE) to whatever the value of the option is: Code: <select onchange="updateLangTo('VALUE')">
<option value="en">English</option>
<option value="ar">Arabic</option>
</select>
So how would JavaScript be able to accomplish this? How can i change this code to do not duplicate the boxes when one option is selected in the same box as before? http://www.plpgolfandturf.com.au/rr/rrboxes_test.php Code: <script type="text/javascript">
function SetHTML2(type) {
//document.getElementById("1").style.display = "none"

//document.getElementById("1.1").style.display = "none"

Hi there - this seems like it should be an obvious problem - can anyone spot it? I have an object, declared this way: Code: var FK_gid = new picChooser('FK_gid', FK_gidArray);
FK_gid.init();
and a select group like this: Code: <select id = "FK_gid" name = "FK_gid"> <option value="none" selected="true" >None</option> <option value="335" >pics/zoobins.jpg</option> etc. etc. </select> picChooser in construction sets the onchange of the select group like this: Code: this.list = document.getElementById('FK_gid');
this.list.setAttribute("onchange", "FK_gid.displayImage();");
and the object's displayImage(); is like this: Code: this.displayImage = function () {
this.clearImage();
if (this.list.selectedIndex != 0)
{
pic = new Image();
pic.src = this.reformat(this.list.options[this.list.selectedIndex].innerHTML);
img = document.createElement("img");
img.src = pic.src;
this.preview.appendChild(img);
}
}
But whenever I choose something else off the list I get this error message: Code: TypeError: Result of expression 'FK_gid.displayImage' [undefined] is not a function. It's bizarre because when I type FK_gid.displayImage(); into Safari's dynamic console the function works perfectly... Any ideas? Thanks Edd All, If I have the following code: Code: <form name="datatoshow" id="datatoshow"> Want to learn more about the sie? Use the drop down menu:<br /> <select name="thingtoshow" onchange="javascript:showvalues(this.datatoshow);"> <option value="home">Home</option> <option value="help">Help!</option> <option value="refer">Refer a Friend</option> </select> </form> This doesn't do anything on the onchange. The code it's supposed to send to is: Code: function showvalues(selObj){
alert("it gets here");
var valuetoshow;
valuetoshow = "valuetoshow="+selObj.options[selObj.selectedIndex].value;
alert(valuetoshow);
makePOSTRequest('showhome.php', valuetoshow);
}
This is in external js file. For some reason it doesn't send it and the alert never gets triggered. Thanks. Hi I'm a newbie. Please help me. I'm using Joomla. I've got a dropdown which reads the filename from the database. When the user selects it I want an onchange event to open the pdf. I've been at it for 2 days now. Code: <?php
$con = mysql_connect('localhost', 'root', '');
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("metnet", $con);
$sql="SELECT * FROM newsletter";
$result = mysql_query($sql);
echo "<form method='post'>";
$dropdown = "<select name='sname' onChange='location(this.form.sname)' >";
while($row = mysql_fetch_assoc($result)) {
$dropdown .= "\r\n<option value='{$row['fpath']}'>{$row['fpath']}</option>";
}
$dropdown .= "\r\n</select>";
echo $dropdown;
?>
I am trying to create an onChange action that will validate that confirmation checkbox has been checked, and if not, popup an alert message and put the focus on the checkbox input and change the class of the container DIV to "highlight". Here is the form, with the 'onchange' trigger: Code: <form id="checkout" name="my_form" method="post" action="!---SCRIPT_NAME---" onsubmit="return validForm(this);"> <div id="verification" class="aligncenter required"> <input type="checkbox" id="verified" name="verified" value="" /> <label for="verified">YES</label>, the items and quantities shown above are correct.</div> <div class="required"><label for="name">Name:</label><input id="name" name="contactname" type="text" class="L" onchange="" /></div> <div class="required"><label for="company">Company Name:</label><input id="company" name="company" type="text" class="L" /></div> <div class="buttonRow"><input type="submit" name="VERIFY" class="btn red" value="Continue" /></div> </form> And here is my javascript code: Code: function verifyOrder() {
if (document.my_form.verified.checked != "true") {
alert("Please verify the contents of your order");
document.my_form.verified.focus();
getElementById('document.my_form.verification').className='highlight'
return false;
}
}
But this is not working and generates errors in firebug. What am I doing wrong? Thanks!! |
