JavaScript - Check Boxes Created Using Javascript Are Not Submitting On Form Submit
Hello,
I have the following DIV tag Code: <div id = "cbContainer"> </div> The div is initially hidden as the display is set to none. I have one text input in my form. Depending upon the changed text in that textbox, there is a javascript function which creates a list of checkboxes and by using the innerHTML, the above div is filled up with the check boxes like shown in the code below: Code: var chkboxes = '';
for(var r = 0; r < related.length; r++)
{
chkboxes = chkboxes +
'<div class ="versionswidth">'+
'<input type="checkbox" name="version" value = related[r] />'+ related[r] +
'</div>';
}
var div = document.getElementById("cbContainer");
div.innerHTML = chkboxes;
div display is then set as "block" which makes the div visible. The problem is that on form submission, the input of selected checkboxes is not submitting. I will be grateful for any help. Thank you. Similar TutorialsI'm trying to understand how forms, data, php, javascript all work together. So 1) I hardcoded some html form fields with values using php using "echo", then 2) I dynamically created some more html form fields with values using javascript using "createElement" and appending to the html form element. When I click on the submit form, the php created form fields still show on the webpage, but the javascript dynamically created form fields disappear. Can anyone shed some light for me? Why are the javascript created form fields disappearing when I click on submit and not the PHP created form fields? Thank you! Code: <form method="post" id="commentform" action="<?php echo $PHP_SELF?>"> Can anyone tell why IE does not handle this form submit properly? Instead of going to the action of the form in formString, it just refreshes the page. Works fine in Firefox and Chrome. Code: Here is how the form is placed on the page and then submitted:
document.getElementById('crtDiv').innerHTML = formString;
document.getElementById('crtForm').submit();
Here is an example of how the formString is built:
formString = "<form action='https://www.paypal.com/cgi-bin/webscr' method='POST' id='crtForm'>";
formString += BUNCH O INPUTS
formString += "</form>";
I have 3 check boxes and one submit button when the submit button is hit I need it to direct to one of 3 pages depending on which check box is checked. can anyone help with this Thanks! I have the following page www.crownvalleywinery.com/kiosk/default.html and I would like to add a button or checkbox to check/uncheck all. Note we are already using some javascript for custom checkboxes so it needs to integrate with that. Any help is appreciated. Here is the current javascript... Code: /*

The only thing you need to change in this file is the following
variables: checkboxHeight, radioHeight and selectWidth.
Replace the first two numbers with the height of the checkbox and
radio button. The actual height of both the checkbox and radio
images should be 4 times the height of these two variables. The
selectWidth value should be the width of your select list image.
You may need to adjust your images a bit if there is a slight
vertical movement during the different stages of the button
activation.

Hi Guys, This is my first post, apologies in advance. I'm new to javascript and working on a form, for some reason the checkboxes work fine in Google Chrome but ar enot working corectly when using IE. Can anyone put me out of my misery? I've attached the code below Thanks in advance Code: //The Javascript

Thanks. I have a problem when submitting through javascript, i have used it hundred times, but i dont know why it refuses to work now, http://two.xthost.info/shailesh/test.htm Please look at the attached file in IE 6 and when you click on "Delete Selected" button, you get javascript error and the form refuses to submit the error is on line document.myform.submit(); Hi I have a problem but im not sure if it could be solved by Javascript or PHP but either is good. I have a form with a text box where users can enter a 10 digit code. The 10 digit code can be just numbers/letters (eg. 0123456789 or abcdefghij) or it can be a mixture (eg. 0a1b2c3d4e). What I would like is if the user enters a code which is a mixture of numbers and letters then the submit url goes to mixed.php If the user enters a code which just has letters or numbers then the submit url goes to sole.php Anybody can help me? I know its possible to change the url from selecting radio buttons so I hope this can be achievable. I hope that makes sense...let me know if you need more info. Thanks guys! I have created a form with javascript embedded to dynamically assign value to
Code: document.myForm.myTextBox.value based on user inputs, and when submitting the form, the targeted php file will process the data and records them in MySQL. The problem is that the value of myTextBox remains 'null' even when the javascript assigns a value to it (and it is visible in the form). Here is the code of the javascript: Code: document.register.street.value = http.responseText.split('^')[0];
document.register.city.value = http.responseText.split('^')[1];
document.register.street.disabled = true;
document.register.city.disabled = true;
To prevent user-mistyping, the textbox will be disabled after the value is set. I tried to search but I found it is very difficult when I don't even know what key word to use to describe this issue. I hope anyone can help me with this here, and thanks for any inputs. I have created a small file where I check if the passwords entered in the code match or not, if they do not match, the button that links to the next webpage should not work(allow them to go to the next wepage). ive tried various websites to help me try and solve this but I just dodont understand what they are doing. I'm very new to programming btw here is some example code: Code: !doctypeHTML
<html>
<script>
//lets just pretend that ive already done all the .getelement by id stuff to get the code things
//suppose the person did not write anything in the form, an error will get pushed(alerted basically)
if(!form['password'].value)
error.push('Missing Password');
<form>
<label>Password<br><input type="password" name="password"></label>
<label>Confirm Password<br><input type="password" name="confirm"</label>
</form>
</html>
now how would I make the submit button not submit if there are errors? please be as simple as possible, I am new to this! Consider the following piece of code: PHP Code: <form method='post' name='myform'> <input type='submit' name='sub' value='submit 1' /> <input type='submit' name='sub' value='submit 2' /> <a href='javascript:document.myform.submit();'>submit 3</a> </form> <?php echo "You clicked ".$_POST["sub"]; ?> So if you click "submit 1", the output will be You clicked submit 1. And if you click "submit 2", the output will be You clicked submit 2. That's obvious. But ... what do I need to do to pass the key/value pair "sub" = "submit 3" to the server via POST when I click on the hyperlink showing "submit 3" - so that the output is You clicked submit 3 (i.e. so that $_POST contains "submit 3" referenced to index "sub"). I've tried <a href='javascript: a = {"x" : 1}; document.myform.submit(a);'>submit 3</a>, but that doesn't cause a to be passed via POST. I've literally tried everything. Read 26 tutorials, interchanged code, etc. My validation functions all work. My AJAX functions work (tested manually using servlet URL's). The second servlet validates the reCaptcha form that's generated on my webpage. After the form is validated, even if everything's correct, nothing happens upon clicking submit. I even have an alert pop up if with the captcha result, just for middle-layer debugging purposes. I want to do all of my validation clientside; none serverside. However, going to be tough if I can't get my god damn form to submit. I've been puzzled by this for close to 36 hours straight. I can't see, and I'm going to get some rest and hope that there is some useful insight on my problem when I return. html form: Code: <form id="f1" name="form1" onsubmit="validate_form(this); return false;" action="register" method="post">

Okay this is part of an ajax driven shopping cart. the problem is i need to check for 2 different selections that would be for the same payment method. here is the code as it sits now Code: if ( typeof document.checkout.payment[3] != 'undefined'){
if (document.checkout.payment[3].checked == true)
{
if (document.checkout.cc_owner.value == "" )
{errMsg += 'Please complete or verify the information in the Name on the card field in the \'Payment Method\' section.' + "\n";
}
else
{
if(document.checkout.cc_number.value == "")
{
errMsg += 'Please complete or verify the information in the Card Number field in the \'Payment Method\' section.' + "\n";
}
else
{
if(document.checkout.cc_cvv2.value == "")
{
errMsg += 'Please complete or verify the information in the CVC/CVV code field in the \'Payment Method\' section.' + "\n";
}
else
{
if(document.checkout.cc_phone.value == "")
{
errMsg += 'Please complete or verify the information in the Card company\'s telephone number field in the \'Payment Method\' section.' + "\n";
}
else
{
myCardNo = document.checkout.cc_number.value;
myCardType = document.checkout.surcharge.value;
if (!checkCreditCard (myCardNo,myCardType))
{
errMsg += 'Please complete or verify the information in the Card Number field in the \'Payment Method\' section.' + "\n";
}
}
}
}
}
}}
}
the problem is in the first 2 lines i basically need it to do this, but when i do it like how i need it to be it will not work. it looks like i am doing it incorrectly maybe. firebug gives me an undefined error on the first checked value because it does not exist when i need it to check for the 2 value. Code: if ( typeof document.checkout.payment[3] != 'undefined' || typeof document.checkout.payment[2] != 'undefined'){
if (document.checkout.payment[3].checked == true || document.checkout.payment[2].checked == true)
{
if (document.checkout.cc_owner.value == "" )
{errMsg += 'Please complete or verify the information in the Name on the card field in the \'Payment Method\' section.' + "\n";
}
else
{
if(document.checkout.cc_number.value == "")
{
errMsg += 'Please complete or verify the information in the Card Number field in the \'Payment Method\' section.' + "\n";
}
else
{
if(document.checkout.cc_cvv2.value == "")
{
errMsg += 'Please complete or verify the information in the CVC/CVV code field in the \'Payment Method\' section.' + "\n";
}
else
{
if(document.checkout.cc_phone.value == "")
{
errMsg += 'Please complete or verify the information in the Card company\'s telephone number field in the \'Payment Method\' section.' + "\n";
}
else
{
myCardNo = document.checkout.cc_number.value;
myCardType = document.checkout.surcharge.value;
if (!checkCreditCard (myCardNo,myCardType))
{
errMsg += 'Please complete or verify the information in the Card Number field in the \'Payment Method\' section.' + "\n";
}
}
}
}
}
}}
}
I am not familiar with javascript only html, but I have researched this problem and found some solutions, but I am unsure what to do with them. I have an html checkbox form that lists book titles. The user will click on the checkbox next to the titles that interest them. Then when they click submit, I want a pop-up box to appear with the titles they selected in a printable list. I found this javascript code: Code: <script langauge="javascript" type="text/javascript">
function openPreview() {
var myWin = window.open ("popup.htm","myWindowName","width=500,height=350");
myWin.focus();
}
</script>
Then here is my html form code: Code: <form action="" form id= "myInput">
<table width="523">
<tr><td width="33"> <input type="checkbox" name="product" value="Ironman"></td>
<td width="229"><div align="left">Ironman</div></td>
<td width="174">Chris Crutcher </td>
<td width="56" align="right"> </td></tr>
<tr><td><input type="checkbox" name="product" value="Staying Fat for Sarah Byrnes">
<th><div align="left">Staying Fat for Sarah Byrnes </div></th>
<td>Chris Crutcher </td>
<td align="right"><tt>Realism</tt></td>
</tr>
<tr><td><input type="checkbox" name="product" value="The Watsons Go to Birmingham">
<th><div align="left">The Watsons Go to Birmingham </div></th>
<td>Chrisopher Paul Curtis </td>
<td align="right"> </td>
</tr>
</table>
<input type="button" id="btnPreview" name="btnPreview" value="Preview" onclick="openPreview()" />
</form>
Then on the popup.htm page I have this code Code: <script language="javascript" type="text/javascript">
document.write(window.opener.document.getElementById("myInput").value);
</script>
This code has worked for me when the form is a textarea or a label, but I don't know how to use it with a checkbox form. I know that labeling the form "my input" only works for textarea or labels, so I understand why the pop-up menu says undefined. What do I need to do to get the checkbox data to appear. I have created a php script that POSTs to another page sendmail.php which then redirects to a thanks/successful page. Is it possible to have the form submit and return a thank you message on the same page. basically submit the form without reloading. I have a simple form and am validating onchange and need a final validation onsubmit. I am displaying a message to the right of the inputbox on error. I'm trying to keep this at DOM 1 compatible and not use any framework. HTML Code: <form id = "myForm" action = "" onsubmit = "return validateForm(this);">
<table class = "table-submit" border = "0">
<tr>
<td>
Username:
</td>
<td>
<input type = "text" id = "username"
size = "30" maxlength = "30"
onchange = "validateUsername(this, 'msgUsername')" />
</td>
<td id = "msgUsername">
</td>
</tr>
<tr>
<td>
Password:
</td>
<td>
<input type = "password" id = "password"
size = "30" maxlength = "30"
onchange = "validatePassword(this, 'msgPassword')" />
</td>
<td id = "msgPassword">
</td>
</tr>
<tr>
<td> </td>
<td>
<input type = "submit" value = "Submit" />
<input type = "reset" value = "Clear" />
</td>
</tr>
</table>
</form>
JavaScript Code: function validateUsername(myItem, myElement) {
var dom = document.getElementById(myElement);
if (myItem.value.length < 3) {
dom.innerHTML = " Username needs to be a minimum of 3 characters! ";
return false;
}
else {
dom.innerHTML = "";
return true;
}
}
function validatePassword(myItem, myElement) {
var dom = document.getElementById(myElement);
if (myItem.value.length < 5) {
dom.innerHTML = " Password needs to be a minimum of 5 characters! ";
return false;
}
else {
dom.innerHTML = "";
return true;
}
}
function validateForm (itm) {
// kind of stuck here...
}
As you may of noticed, I am a bit stuck on my validateForm() function. The code validates on each inputbox onchange event. Not sure what is the best way to go from here. I thought about doing an If for my both single input box validation, but I would need to send each parameters which is what i was trying to avoid by using this. Would like some suggestions. I am just starting out using Javascript and created a simple knowledge check to give a learner feedback on a question. It will allow the learner to quickly check if they have mastered a topic. The problem that I am having is that if I put two of these knowledge checks on the same webpage than it just posts the same answer when the submit button is clicked. What I have been doing is just pasting the code below twice on the page and changing the question and answer out. When I click "Check Answer" it is the same answer for both questions. Here is my code: Code: <fieldset>
<legend><strong>Question 1</strong></legend>
<SCRIPT LANGUAGE="JavaScript">
function readText (form) {
TestVar =form.inputbox.value;
alert ("You typed: " + TestVar);
}
function writeText (form) {
form.inputbox.value = "The wavelength of the blue light scatters better than the rest, predominates over the other colors in the light spectrum, and makes the sky appear blue to us."
}
</SCRIPT>
<form name="myform" action="" method="GET">
<label for="question">Why is the Sky Blue?</label><br><br>
<input name="inputbox" value="" type="text" style="width: 287px; height: 112px">
<p>
<input id="question" value="Check Answer" onclick="writeText(this.form)" type="button">
</p>
</form>
</fieldset>
Any help would be much appreciated in terms of direction. Thank you. |
