Possibly a silly question, but how do I prevent a select element in a form from showing its drop down menu when it's clicked on? I tried the following:
$('select').click (function (e) {
console.log (e);
return false;
});
and
$('select').click (function (e) {
e.preventDefault ();
console.log (e);
});
But neither worked.
What am I doing wrong?
EDIT: The reason I need to know is for a jquery enhanced select element that needs to degrade gracefully. The idea is the select, when clicked, opens a jquery UI dialog with a nicely maked up list that the user makes their selection from (clicking a list item causes the select's value to update). If JS is disabled then the select should just operate as normally.
The problem is that as well as the dialog opening, the dropdown also appears, which is not what I want. I can't just disable the control, as its value needs to be submitted along with the rest of the form.
This should work:-
$('#select').on('mousedown', function(e) {
e.preventDefault();
this.blur();
window.focus();
});
The problem is that you're using the wrong event.
<select onmousedown="(function(e){ e.preventDefault(); })(event, this)">
<option>Some Option</option>
</select>
JsFiddle
From my experience, if i need to disable something, the easiest way to have another invisible element on it (use absolute positioning). When you want to allow default behavior again, you just hide absolute element.
I believe the best solution would be to replace the select element with something else to click on (a button or a link).
BTW, you may want to look into the CSS 3 property appearance, which theoretically allows you to let that replacement element look like a dropdown. Support is however currently very limited:
http://css-infos.net/property/-webkit-appearance
https://developer.mozilla.org/en/CSS/-moz-appearance
You can, the trick is to cancel the mousedown event, not the click. The event chain is made in such a way that click and mouseup cannot occur if mousedown was cancelled:
function cancelDropDown(ev) {
ev.preventDefault();
}
document.getElementById("selectElement").addEventListener("mousedown", cancelDropDown, false);
Hide the select options on page load (if Javascript enabled). They will not display when the select box is clicked, but the text of the first option ("Select an option", or whatever) will still appear in the select field.
$(document).ready(function() {
$('#idOfSelect option').css('display', 'none');
});
Updated Solution:
$(document).ready(function() {
$('#idOfSelect').focusin(function() {
$(this).css('display', 'none');
$('body').click(function(event) {
$(this).unbind(event);
$('#idOfSelect').css('display', 'block');
});
});
});
I just solved this exact problem, by manipulating the 'size' attribute of select. Not very elegant, but worked. Hope its of some help to you.
<!-- Example select dropdown -->
<select id="select" onclick="tackleDropdown()">
</select>
<!-- The JS function -->
<script>
function tackleDropdown(){
document.getElementById('select').setAttribute('size', 0);
// your code for displaying the jQuery UI dialog (is it colorbox???)
// re-enabling the drop down
document.getElementById('select').setAttribute('size', document.getElementById('select').options.length);
}
</script>
Use disabled
$(this).attr("disabled","disabled");
Some good answers here. But still I had to make some additions.
$(document).on('keydown mousedown touchstart', 'select.disabled', function (e) {
e.preventDefault();
})
A simple solution based on CSS is this small fragment:
select:read-only * {
display: none;
}
This will make the options not available when the select is selected. This action mimics the behavior of the "readonly" attribute of the input.

I've got a little autocomplete dropdown which I want to hide when someone clicks outside the textbox. I've been using this so far
$("#input-group_ids").on("blur", function () {
$(".input-dropdown").hide();
});
However my autocomplete dropdown has an overflow and a scroll bar if there are more than 10 options. When using the above code, clicking on the scroll bar closes the dropdown.
I need the dropdown to close only if the click is outside the textbox AND the dropdown itself. How do I do that?
Not yet tested hope this will work
$("html").click (function () {
$(".input-dropdown").hide();
});
$("#input-group_ids, .input-dropdown").click (function (e) {
e.stopPropagation;
}
In case you won't get clear with the blur event, try to register the click event to an element that is surrounding both the textbox and the dropdown. It may even be the body.
Then in the click event check the event.target element. If it is neither the textbox nor the dropdown, close it.
It feels clumsy, I know, but it is one of several working options.
Try this :
$("*:not(#input-group_ids)").on("click", function () {
$(".input-dropdown").hide();
});
Not tested because you didn't gave any jsfiddle
Have you tried the not selector the name explains it all and might work if you have a container on the dropdown and textbox
a little hackish but might work.
$(elementContainingTheDropDownContent).on('mouseleave', function(e){
$(window).on('click', function(e){
//close dropdown
})
}).on('mouseenter', function(){
$(window).off('click');
})
I found another answer to this which is actually the best version I think
$(document).click(function(e) {
if (!$('#input-group_ids').is(e.target) && !$('.input-dropdown').is(e.target))
$('.input-dropdown').hide();
});
This is slightly better than Benjamin's answer as it doesn't stop propagation of any clicks on $("#input-group_ids"), which may have unintended consequences. However I'm accepting Ben's answer as it worked and solved my problem, and he deserves the credit. =)
EDIT: Actually my version is pretty similar to #singe31's version, so I upvoted that one too
I have two buttons and I need one to stay disabled until the other is active. And then I need that same button to become inactive and go back to a previous class if the first button is clicked/toggled again. I only have have access up to jQuery 1.7.2:
<button class="primaryClass" value="primary"></button>
<button class="linkClass" value="link"></button>
Thus far I tried this but it does not seem to be working:
$('.linkClass').on('click touchend',function() {
if($(this).hasClass('linkClass')) {
$(this).prev('.primaryClass').addClass('disabled');
e.preventDefault;
}
if($(this).hasClass('linkClass-active')) {
$(this).prev('.primaryClass').removeClass('disabled');
});
So basically, the user clicks the button with linkClass the button with primary class becomes enabled because the disabled class is removed. If the user clicks it again, then the primaryClass button again becomes disabled. Any ideas what I am doing wrong?
Your question is fairly vague, please try to make a fiddle. As far as I can tell you should be setting .prop("disabled", true); to make the button disabled. If you don't have a css .disabled class, you won't see it, that and you should always use built in functionality.
Instead of adding the class you can disable the button using the disabled property. This will prevent clicks on the button from firing any event handlers.
$('.linkClass').on('click touchend',function() {
var primary = $("button.primaryClass");
primary.prop("disabled", !primary.is(":disabled"));
});
JS Fiddle: http://jsfiddle.net/6SNQS/2/
use toggleClass
http://api.jquery.com/toggleclass/
$('.linkClass').on('click touchend',function() {
$(this).prev('.primaryClass').toggleClass('disabled');
e.preventDefault;
});
The part with 'linkClass-active' I don't understand so I left that out.
If you want to also toggle the disabled property use this:
$('.linkClass').on('click touchend',function() {
var $target = $(this).prev('.primaryClass');
$target.toggleClass('disabled');
$target[0].disabled = !$target[0].disabled;
e.preventDefault;
});

By the way, why are you setting value? its not an input its a button tag.
You mean like this DEMO:
html
<button class="primaryClass" disabled="disabled" value="primary">Bye</button>
<button class="linkClass" value="link">Hi</button>
js
$('.linkClass').on('click touchend',function() {
$(this).prev().prop('disabled', function(idx, oldAttr) {
return !oldAttr;
});
});
jQuery attr() takes a callback. So you can use that to your advantage.
I am working on a functionality where in when someone hover on to a block a form appears, I have used mouseover and mouseout functions to show the and hide the form. When we are selecting any option form these selection option, which are flowing out of the block range the form block is disappearing which is a flaw.
I have written the below jQuery
jQuery(function(){
jQuery(".find-a-doc").mouseout(function(){
jQuery(".doctor-con").css("display","none");
});
jQuery(".find-a-doc").mouseover(function(){
jQuery(".doctor-con").css("display","block");
});
jQuery("#edit-field-department-latest-value").bind("change", function() {
alert('Value change to ' + jQuery(this).attr('value'));
if(jQuery(this).attr('value')>=1)
{
jQuery(".doctor-con").css("display","block");
}
else
{
jQuery(".doctor-con").css("display","none");
alert('value selected is less than 1');
}
});
});
I want the form block to be displayed when any section is made from the selection box.
I'd first recommend changing to the .on jQuery method (as the bind live and delegate methods are deprecated) and then try binding your mouseout event to both the container and form fields, or possibly just the form fields, if you set up a jsfiddle with your html css and js for this I'll gladly solve it for you.
Was styling the checkboxes of my webpage with jquery using the tutorial here
But i realized that I could not do SelectAll checkbox that will select all the checkboxes in my list. It works in the backend (the checkboxes are selected) but it does not show in my page.
Added a demo to show my problem. May need to port to your system to test it out
Demo
what can I add to the jQuery Custom Radio-buttons and Checkbox javascript file in the to achieve the select all checkbox function
Thank you!
You can try this FIDDLE:
$(function () {
var $chbxs = $('.checkbox');
$('#sel_all_lbl').toggle(
function() {
$chbxs.css('background-position', '50% -50px');
$('#checkboxall .truefalse').prop('checked', true);
},
function() {
$chbxs.css('background-position', '50% 0px');
$('#checkboxall .truefalse').prop('checked', false);
}
);
});
What I've done? First, in your fiddle you need to correct some syntax errors, then add a plugin code to the DOM, and you scripts to the script panel, so they will fire when DOM is ready. (This is all about jsFiddle, so you to understand how it works)
About actually your code, you attached click-handlers (.toggle()) to the checkbox element. But click event does not fire on it. Script simply changed the property of the checkbox, but there is no click. So you need to attach these handler to the element wish user actually clicks, that is square icon. (I added an id="sel_all_lbl" to it)
Try to use event handling on the select all checkbox and manually check all the checkboxes from javascript.
Is there a way to disable (with CSS, JS or jQuery) double-click for a given element?
The problem with Opera is that it displays a menu when I click on an element too fast. Note that I know how to disable this for me. I'd like to be able to disable this for all user that use the script.
The buttons in question are "next"/"previous" buttons and I use input type image for them, but the same happens with "a".
It turended out I need this:
/**
Disable text selection by Chris Barr, of chris-barr.com
*/
$.fn.disableTextSelect = function() {
return this.each(function(){
if($.browser.mozilla){//Firefox
$(this).css('MozUserSelect','none');
}else if($.browser.msie){//IE
$(this).bind('selectstart',function(){return false;});
}else{//Opera, etc.
$(this).mousedown(function(){return false;});
}
});
}
And then I could disable text selection on my button elements like this:
$(function(){ $('input[type=image]').disableTextSelect(); });
And now I can click buttons fast as hell and all works fine :-).
You cannot have a click and dblclick event handler attached on the same element because when you dblclick both the events are going to be triggered. In order to make it work there are few work arounds.
This might help you
Need to cancel click/mouseup events when double-click event detected
Looking at your problem there is a simple solution. In the click event handler once it is clicked set a disabled attribute or some class name(disabled). In the handler before exectuing your code checck for this attribute or class name. If it exists then dont do anything. After sometime remove this attribtue or class name. Try this
$("selector").click(function(){
var $this = $(this);
if(!$this.hasClass("disabled")){
//Do you stuff here
$this.addClass("disabled");
setTimeout(function(){
$this.removeClass("disabled");
}, 200);
}
});
JavaScript would do that for you.
DOMElement.ondblclick = (function () {return false;})();
