Add Readonly Attribute Dynamically To Input Tag

Jul 23, 2005

When accessing my web page I build up the javascript and html dynamically. Depending on an parameter I want to set all the fields (input tags) readonly. How do I do this? Of course I can write if statements to add different input tags with and without the readonly attribute. But is it possible to write a javascript that onload search the page and add readonly to all input tags?

Dynamically Set Readonly - Input Field ?

Jan 22, 2009

There are two ways for me to make a input field readonly:


In a JSP, I use <input type="text" id="test" readonly="readonly" value="1234abc" />

The field will become readonly--I can not edit the text in the field. This is what I wanted.

2) Dynamical:

But sometimes I need to achieve this at the runtime/dynamically:

Now in the javascript:

The field will display as readonly. However, I can actually highlight the text, delete and edit it.

JQuery :: 'input:text' Selector Not Finding Input Element With No Type Attribute?

Mar 16, 2011

As recently as 1.4.3 $('input:text') would find input elements with no type attribute, but after upgrading to 1.5.1 that is no longer the case.

Is this a bug or an intended refactor to be more standards compliant?

FYI - this is the selector I now have to use: $('input:text,input:not([type])')

Object Doesn't Support This Property Or Method - Dynamically Add An Attribute To Some Elements

Jul 15, 2010

I get an error when I try to dynamically add an attribute to some elements, since I been getting the error "Object doesn't support this property or method" in IE I reduced the attribute value to just alert.

Code JavaScript:

Note that in firefox all the elements with the class boxcontainer gets "hello world" alert. I removed this specific code (shown above) out of the page and the error in IE goes away, so I'm 100% sure nothing else is causing it.

Form Attribute Action And Input With Same Name

Jul 23, 2005

I want to change attribute action in form. Problem is that in that form
is also input with name action. Unfortunately renaming of that input is
worst case because many servlets depend on it.

This works in konqueror but not in IE and Mozilla:

newurl= document.forms[i].getAttribute('action');
newurl= newurl.replace('all/', prefix);
document.forms[i].action= newurl;

Do you have any idea how to modify attribute action in this case ?

JQuery :: Getting Value Attribute Of Input Element ?

Oct 2, 2010

I have a table with several columns containing input elements populated from a database, e.g.,

On every row, I need to perform a calculation using the value of several input fields. So I tried to access the value of the first input field like so (which had worked in another function):

But for some reason it's returning a 0, and the line below also doesn't work:

But this returns the correct class, so I know it's finding the element:

And if I assign the input element an id, say "count," this works:

Obviously I don't want to fuss with individual id's to get the values. How to understand why the first two examples don't work, and how to fix them?

Missing Name Attribute From Dynamic Input Element

Sep 28, 2006

I'm attempting to submit a form via a function which dynamically creates a
hidden input:

function submitLocation(theForm) {
var e = document.createElement('input');
e.setAttribute('type', 'hidden');
e.setAttribute('name', 'location');
e.setAttribute('value', &#391;');
var f = document.getElementById(theForm);

The function is called from an anchor's onclick event:

<form name='form1' method='post' action='action.php'>
<a onclick="submitLocation('form1');">Submit</a>

However the function produces an input which is missing the name element:

<INPUT type=hidden value=1>

The desired output should be:

<INPUT type=hidden name=location value=1>

Retrieving Value Of A Dynamically Created Input Field

Feb 12, 2011

I've dynamically created a new field by using appendTo.


PHP Code:

$("<input type='text' id='field' value='1'>").appendTo("body"); 

If I try to access the value of this dynamically generated field (i.e. $("#field").val()), I don't have any value returned. I understand this may be because jquery doesn't detect it as being a part of the DOM or something along those lines.

Readonly Textbox With Scroll

Jul 23, 2005

I am stuck with a problem trying to mimic the behavior of a Windows
Forms Readonly textbox in HMTL/ASP.NET.

Basically, I would like the text to be readonly and overflow the
textbox (overflow attribute) with the user being able to scroll thru
the text using the arrow keys within the textbox.

I managed to get the readonly and the overflow part to work but cannot
figure out a way to let the user place the cursor within the box and
allow scrolling within a readonly textbox.

Problem Removing ReadOnly In IE

Dec 1, 2006

I am having trouble with the following code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
<html xmlns="" xml:lang="en" lang="en">
<input value='test' type='text' readonly='readonly'
onfocus='this.readOnly = false;'
onblur='this.readOnly = true;'></input>

In FF, this works as I would expect. When clicking on the input, the readOnly
property is set to false and the focus is given to the element, with the
cursor placed after the last character.

In IE, the readOnly property is set to false, but the element isn't actually
given focus. Instead, I have to click on the input a second time in order to
actually input text with the keyboard.

Is there a way to make this work the same in IE as it does in FF? I have
tried things like calling this.focus() and after setting
readOnly to false, but they have no effect.

Readonly Select Element

Jul 20, 2005

I have need of a readonly select element that looks and acts disabled to
the user. The problem with the disabled attribute is that the value
isn't passed to the handler, so I'm using readonly. Problem with
readonly is that is allows focus, which when the user highlights, then
hits backspace (as if to change the field), the browser does a
history.back. This is confusing to users. Code:

Make A <select> Readonly In IE6?

Aug 13, 2010

I'm having an issue making a <select> box read only. Disabled works in that it greys it out and prevents the user from changing the value, but it also doesn't submit the value to the server (as expected). On regular inputs the readonly attribute seems to work but when applying readonly to a select, it changes nothing. It doesn't grey out the element and I can still change the value. I've done a bit of searching but can't find anything for IE6. This is for an intranet where the target is 100% IE6 so I don't care if it doesn't work in other browsers. It must be IE6 ...
