Input fields get (readonly) after hit submit button

I have a script which is coded in PHP and smarty and I want to make some changes in this script like in user profile setting when a user click on profile setting and fill the profile data like (full name , email , bank account number , bank name , branch code , tile etc) after fill this information and click the save button the script save all setting but I want to make some of form input fields (readonly) after user submitted his/her data I want make this data (readonly) (bank name , account number , branch code , title) I mean about readonly that after user fill this and save it in profile its show to user (readonly) user can't change it only I can change it from database .
Below is the form code
<form id="settingsform" onsubmit="return submitform(this.id);">
<input type="hidden" name="a" value="submit" />
Bank Name:
</td>
<td><input type="text" name="bank" id="bank" value="{$user_info.bank}"></td>
</tr>
<tr>
<td align="right" width="50%">
Bank Account Number:
</td>
<td><input type="text" name="baccount" id="baccount" value="{$user_info.baccount}"></td>
</tr>
<tr>
<td align="right" width="50%">
Bank Account Title:
</td>
<td><input type="text" name="btitle" id="btitle" value="{$user_info.btitle}"></td>
</tr>
<tr>
<td align="right" width="50%">
Bank Branch Code:
</td>
<td><input type="text" name="bcode" id="bcode" value="{$user_info.bcode}"></td>
</tr>
<input type="submit" name="btn" value="{$lang.txt.send}" class="orange" />
also i am already trying like this below
<script>
function hide(){
document.getElementById("bank").disabled = true;
document.getElementById("baccount").disabled = true;
document.getElementById("btitle").disabled = true;
document.getElementById("bcode").disabled = true;
}
</script>
and
<input type="button" onClick="hide()" value="save">

<input type="text" name="country" value="Norway" readonly>
http://www.w3schools.com/tags/att_input_readonly.asp
Then simply do a check if the POST/GET is set for the field you want to have readonly on ->
<input type="text" name="country" value="Norway" <?php isset($_POST['country']) ? echo 'readonly' : ''; ?> >
UPDATE
<input type="text" name="country" value="Norway" <?php isset($user_info.bank) ? echo 'readonly' : ''; ?> >
Just replace the variable inside of the isset() with the variable of the field, depending on how you initialize the variables you might need to use
empty()
instead, to do so just simply replace isset() with !empty()
The reason for the ! sign is to tell the code to execute the first bit (the echo part) if the variable ISN'T empty
UPDATE 2
<input type="text" name="country" value="Norway" {if isset($user_info.bank) } readonly {/if} >
Above code should work with smarty how ever, the idea is simple, simply have a "if" sentence that checks whether the variable is set/have data, and if it does, then echo 'readonly' in the input field

Try to use attr() in submitform() like,
function submitform(id){
....
....
$('#bank,#baccount').attr('readonly','readonly');
return false;
}
Updated,
function hide(){
$("#bank,#baccount,#btitle,#bcode").prop('disabled', true);
}
Or try,
function hide(){
$("#bank,#baccount,#btitle,#bcode").attr('disabled', 'disabled');
}

Javascript Empty field validation - Cannot read property 'value' of undefined

I have been researching for days and taken several example from here for a solution to validate a date fields to make sure it is not empty before moving to next page. but keeps getting cannot read property of undefined, and I have tried using Joomla build validate.js which will not work inside this custom component, and I am hoping for some help here to tackle this issue.
Here's the javascript
nextpage:function(){
var deliveryy=document.getElementsByName("customPlugin")[0].value;
if(delivery == "" || delivery == null) {
alert("filled out All Delivery Date & Time");
return false; } else { .........
Here's the onclick button
<button type="button" id="productbuilder_next" class="productbuilder_pagination pbbutton btn" onclick="productbuilder.nextpage();"> Next</button>
Here's the raw data of the field I am trying to validate that it is not empty
<input id="<?php echo $class.$rand ?>" class="required <?php echo $class ?>" required="true" type="text" value="" size="<?php echo $this->params->custom_size ?>" name="customPlugin[<?php echo $viewData[0]->virtuemart_customfield_id ?>][<?php echo $this->_name?>][comment]"><?php if($this->params->custom_populate_alternate_field){?> <input type="text" id="alternate<?php echo $rand?>" size="30">
Generated
<input id="vmcustom-datetime1930516000" class="required vmcustom-datetime hasDatepicker" required="true" type="text" value="" size="10" name="customPlugin[176][datetime][comment]">

You're looking for a name that doesn't exist in the DOM. In this way, it'll throw this error when you access the property value.
Classes can be used here. Just add a class in your element and search for it in your function.
HTML:
<input id="vmcustom-datetime1930516000" class="required validDelivery vmcustom-datetime hasDatepicker" required="true" type="text" value="" size="10" name="customPlugin[176][datetime][comment]">
JS:
var validDelivery = document.getElementsByClassName("validDelivery")[0].value;
JSFiddle: http://jsfiddle.net/t1g7cfrb/1/
Give it a try and let me know if it helps!

Name of your element is "validDelivery customPlugin[176][datetime][comment]"
And you want to handle it with getElementsByName("customPlugin"). It's incorrect.
You may for example add class customPlugin to element and handle it with getElementsByClassName("customPlugin")[0].

Adding a item into a cart automatically using javascript

Hi i have a cart that i want to add a form automatically this code seems to kinda do the trick only the problem is i have to hit F5 for it to add the amount i am quite new to this and cant figure out where i have gone wrong.
<form method="post" action="level3.php" class="jcart" id="foo">
<fieldset>
<input type="hidden" name="jcartToken" value="<?php echo $_SESSION['jcartToken'];?>" />
<input type="hidden" name="my-item-id" value="ABC-8" />
<input type="hidden" name="my-item-name" value="Level 1" />
<input type="hidden" name="my-item-price" value="95.00" />
<input type="hidden" name="my-item-url" value="" />
<table>
<tr>
<td width="65%">
<strong>Level 1 all for £95</strong>
</td>
<td width="15%" align="right">
£95.00
</td>
<td>
<input type="text" hidden ="true" name="my-item-qty" value="1" size="3" hidden="true" />
</td>
<td width="20%" align="center">
<input type="submit" name="my-add-button" id="my-add-button" value="add" class="button" />
</td>
</tr>
</table>
<input type="hidden" name="visited" value="" />
</fieldset>
That is the form that submits the amount into the check out.
<script>
$(document).ready(function(){
//Check if the current URL contains '#'
if(document.URL.indexOf("#")==-1)
{
url = document.URL+"#";
location = "#";
} else {
location.reload(true);
document.getElementById("my-add-button").click();// Simulates button click this has to be in as it links to another piece of java that adds the item to the check out with out this it wont add the item
document.foo.submit(); // Submits the form without the button
}
});
</script>
document.getElementById("my-add-button").click();
The code above links to the code below that adds the items from to my knowledge
$('.jcart').submit(function(e) {
add($(this));
e.preventDefault();
});
Thank you in advance for any help or suggestions

If i understand correctly, you increase some value of cart in PHP and than want to update quantity on page without refreshing page.
I made little JSFiddle: http://jsfiddle.net/7SbBA/
Basically use ajax:
$.ajax({
url: 'example.com',
data: /* pass product id here */
success: function(){
/* update quantity you want */
}
});
There is some html change too.
UPDATE
If you want updated total values on page load, just £<span class='amount'><?php echo $product['quantity'] * $product['price'] ?></span> and there is no need to use jquery/js for that. But if you still want dynamically update on window load, i updated my JSFiddle v.2

how to set form value with external select value

so i am using the play framework and I'm try to create multiple submit buttons that call the one form:
So what I have is a list of strings, and i would like to create two buttons that will go back to the server and complete an event, the first is send the second is cancel. What i would like to also do is set the source value equal to what is selected in the foo select object. How would I go about doing this? Do i need to create a javascript even that is fired from the form and then get the var inside that function and then fire off the submit? Im not 100% familiar with play framework and scala, so im not sure if i can get it somehow inside this code without using a new method.
#(myList: List[String], theForm: Form[Obj])
#import helper._
#main("myVar Controller") {
<select id="foo">
</select>
<table border="1">
<tr>
#for(myVar <- myList) {
<td>#myVar
#form(routes.Application.method()) {
<div id="hiddenForm" style="visibility:hidden">
<input type="text" name="commandID" id="commandID" value="10" /> //Send Code
<input type="text" name="source" id="source" value=**"Put selected value of foo here" />**
<input type="text" name="destination" id="destination" value="#myVar" />
</div>
<input type="submit" value="Send" />
}
#form(routes.Application.method()) {
<div id="hiddenForm" style="visibility:hidden">
<input type="text" name="commandID" id="commandID" value="18" /> //Undo code
<input type="text" name="source" id="source" value=**"Put selected value of foo here" />**
<input type="text" name="destination" id="destination" value="#myVar" />
</div>
<input type="submit" value="Undo" />
}
</td>
}
</tr>
</table>
}

First of all, the html isn't valid.
You should first make sure that there aren't elements that have the same id.
You have to use javascript to change a value in your form.
I'm not familiar with scalar or playframework, but if they allow you to use jQuery, I recommend the following solution.
$("#foo").bind("change", function(){$("#source").val($("#foo").val()));});​
example:
http://jsfiddle.net/RubenJonker/a8a8p/5
If they don't allow you to use jQuery, then you should put some javascript in the onchange event of the select.
<select onchange="document.getElementById('source').value = this.value">
</select>
example:
http://jsfiddle.net/RubenJonker/a8a8p/4

Incase anyone else has this problem I used the following to solve my problem: Thanks Ruup as your code was the reason why I solved the problem
html:
<select id="foo" >
<option></option>
<option value="test">test</option>
</select>
<input type="text" value="" name="field" id="field" />​
and javascript:
$(document).ready(function() {
obj = document.getElementById("foo");
obj.onchange = function()
{
var elements = document.getElementsByName('field');
for (i=0;i<elements.length;i++)
{
elements[i].value = $('#foo').val();
}
}; });

Problem in form validation with JavaScript

The editvalidate() function is not getting called at all:
Please suggest why. What's the remedy?
<script type="text/javascript">
function editvalidate() {
var emailExp = /^[\w\-\.\+]+\#[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/;
var numericExpression = /^[0-9]+$/;
if(document.editprofile.userid.value == '' || document.editprofile.password.value == ''||document.editprofile.name.value == ''||document.editprofile.age.value == ''||document.editprofile.collegeid.value == ''||document.editprofile.mobile.value == ''||document.editprofile.address.value == ''||document.editprofile.department.value == ''||document.editprofile.email.value == ''||document.editprofile.sec_ques.value == ''||document.editprofile.answer.value == ''){
alert("Hey! you can't left a field blank!");
return false;
}
else if(!document.editprofile.email.value.match(emailExp)){
alert("You need to enter a valid email address to get proper notifications!");
return false;
} else if(!document.editprofile.mobile.value.match(numericExpression)){
alert("Mobile numbers are all numeric digits i think!");
return false;
} else if(document.editprofile.mobile.value.length < 10){
alert("Mobile number must be 10 digit long!");
return false;
}
else{
return true;
}
}
</script>
the form is given below and its used to fetch data from database and itself getfilled with the values.the editable entries are corrected and the form is submitted.its working fine just not getting validated cz the editvalidate() is not getting called at all.why?

i checked it the way u suggested and found that the function is getting called.but why the rest alerts r nt visible? isnt thatdue to the value attribute in input tags

With the as far given little information, all I can answer is: Just run a Javascript debugger. I can recommend you Firebug for this.
That said, in the future please come up with an SSCCE instead of cutouts of code with unnecessary clutter. This avoids crawling long in the code searching for lines of relevance and at first glance obvious questions as "Are they in the same file?", "Did you add alert('blah') as 1st line of function to see if it actually is invoked?", "Did the browser have JS enables?", "Are you sure that you didn't typo'ed the function name?", "Isn't there more into the code which may have disturbed it?", etcetera.
Here's a basic example of such an SSCCE:
<!doctype html>
<html lang="en">
<head>
<title>SO question 2063598</title>
<script>
function validate(form) {
alert('Validate method invoked!');
return false;
}
</script>
</head>
<body>
<form onsubmit="return validate(this)">
<input type="text" name="foo" class="required">
<input type="submit">
</form>
</body>
</html>
That said, I see that you're still using the legacy scriptlets in your JSP. If you can, I strongly recommend to stop using it and switch to taglibs/EL before it's too late. Raw Java code belongs in Java classes, not in JSP files.
Basic example with JSTL's (just drop jstl-1.2.jar in /WEB-INF) c:forEach:
<table>
<c:forEach items="${users}" var="user">
<tr>
<td><input type="text" name="address" value="${user.address}"></td>
<td><input type="text" name="email" value="${user.email}"></td>
<td><input type="text" name="college" value="${user.college}"></td>
</tr>
</c:forEach>
</table>
And also keep CSS in its own CSS file to separate style from content and to increase webapp performance and maintainability.

you don't call it anywhere from your html, you should probably call it <form onsubmit="return editvalidate();">
Ok now I see he formatted it properly, I don't mind the down votes I give them sometimes as well.
#Robin Agrahari
you probably have somewhere typo in the javascript no one is going to go trought it but you, try to test one by one if by using alert as you do. But don't do it on sumbit, create a mock button that will call(on click) this function editvalidate(); and check your function thoroughly and you will get to the problem eventually

How can you tell it's not being called? I'd put an alert right at the top of the method and see if it hits that. It's possible you're hitting some kind of error somewhere. If an alert at the top of editvalidate doesn't occur, try changing the obsubmit to:
onsubmit="alert('hello!'); return editvalidate();"
then you should at least see "Hello!" when you click the submit button.

looking at the code it should be called
Or Try
onsubmit="editvalidate(); return false;"
Or check where it is not misplaced, I mean the javascript should be in <head> </head>

actually i used a password checking parameter in the first if block document.editprofile.password.value == ''
and i never used an attribute like password in the form.that was my mistake and so it was not working.i found it using the firebug tool.thanks for the help.
