I don't know if this is possible or not.
I have a dynamic form with contents that are dynamically created. Every time a button is clicked, a new div element is added. And what I wanted to do is to make the previous div not editable, that is, the input fields could not be used, buttons could not be clicked.
Is it doable?
Thanks.
Try something like this:
// Disable all input-like elements in the divs except for the last div
$(".divclass:not(:last-child) :input").attr("disabled", true);
Where divclass is the class of the divs you mentioned.

Maby something like this? http://jsfiddle.net/ng4Ct/2/
If you can access your previous div elements you can add attribute disabled="disabled" to them.
You can fire the code that adds the disabled attribute to required elements on the same button click function.
Well, you can either access the specific elements inside the DIV and disable them using Javascript, or you can access the DIV and then loop through all the elements inside (probably preferable), and disable them automatically with Javascript.
Of course it depends on how your code is written, can you provide some of the code that generates the DIVs?

I am trying to make element lets say button active on page open. By active I mean when u pressing tab buttons elements, tabs and stuff us getting active one after one. But how can I achieve that element is selected defaulty on page start.
Try using:
element.focus();
Link to javascript documentation
All HTML elements have a Boolean attribute autofocus. It does not only work on form elements such as buttons, input fields, dropdowns, but also on focussable elements like <div contenteditable="true">.
just wondering if it's possible to change a div to an input at a certain breakpoint?
I have a div that contains some names in and then when I switch to mobile, I want this div to become editable so I can change the names.
I guess I have 2 options, change the element type or make the onChange function only applicable on mobile.
is either possible?
can post code but essentially just want a guide or solution how to do this
First, to detect a mobile browser, you can use
if(/Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
Then, on your page, use two elements - the div and the input (or a textarea) and just keep one of them hidden at all times. It seems like you want to listen for a click on the DIV to enable the INPUT, or? And you'll want a key listener on the input to update the DIV as well as another listener to handle hiding the input field and showing the DIV again
I have a javascript function Display(args...) that modifies the content of a modal window depending on which button is pressed. The function contains other attributes that are hidden or displayed (depending on the arguments that are being passed). Where I am going crazy is that a particular div section refuses to hide/display. Let's say that initially I set it up to be hidden/display:none, then onClick is suppose to be display it; even if I invert the initial state the expected behavior does not occur. I set up the debugger and I see that is trying:
if ($('#SectionRefusingToShow').is(":visible") == false) {
$('#SectionRefusingToShow').show();
}
I see it enters the if statement but still not shown. Inspecting the DOM, its element attribute display:none was not removed. For other classes and ids the hidden are properly removed/added. I am using .show for this one given that hidden state for it did not work either!
I have had a similar problem before, and it turned out that I had multiple elements with the same ID value. Have you checked for that? jQuery can get a little fussy when you select elements by ID, and the ID is not unique (which is technically invalid, so it get's fussy for a good reason).
With JavaScript is it possible to have a drop down menu display a form field with an input type of text, instead of a list option? Could I get a jsfiddle demo example?
I recommend using JQuery to do this? Basically hide and show a div with all your input fields on it. This way you can create the illusion that it's a native dropdown. A standard dropdown does not support custom markup. There are aloso third party alternatives for "custom dropdowns" I suspect they are all implemented using some variation on what I suggested above...
Of course it is possible, but I doubt it is possible using a common <select> element. You should probably create a <div> consisting of several inputs (i.e. <input type = "text">).
Then you'll have a button (with a down-pointing arrow image :) ) and to its onclick event, you'll bind a function that shows your <div>. To hide the <div>, you can bind the hiding function to a click on the background or another click on your button.
To add some elegancy and create a dropdown effect while showing the <div>, you can set its height to 0 and then continually increment it with a timer.
I need to hide a text input field with javascript. Changing its type attribute to hidden does not work in IE (security issue).
What would be the best way to do it?
Note: No jQuery or other lib can be assumed.
I assume you have to show and hide the text field dynamically based on changing conditions in the form, otherwise you'd just make it an <input type="hidden"... to begin with.
Keep your code that shows and hides the field as it is, but also catch the onsubmit event.
In the submit handler, get your text field via document.getElementById(...) (or by accessing document.forms[i]) and check to see whether or not it's hidden.
If it is hidden, create a new DOM node for an <input type="hidden" ...> field and add that node to the form, probably via myform.appendChild(...). You'll have to give it the name your server-side code expects. Copy the contents of the hidden text field into the newly created type=hidden field, then return from your submit handler, allowing the standard submit to continue.
You could also just un-hide the text field on submit, but you'd have to move it "off screen" also or the user would see it reappear during submit processing.
Try wrapping it in a div or span and then setting the display style to none when you want to hide it, and then to block (if you used a div) or inline (if you used a span) when you want to show it.
document.myform.myelement.style.display = 'none'
works as expected even in Internet Explorer.
The only way you can change it is before you append it to the DOM. You can make a new element and then replace the current one with it.
Look at replaceChild and createElement since you want to do manual DOM scripting. I assume you know what to do.
EDIT: "Hidden" fields as far as I know are sent. Have you checked whether they are? And you can also just do position:absolute; left:-9999em; to offset them.
