I'm using a JQgrid in one of my projects (JFiddle LINK). and would like
1.) the save & cancel button to highlight when a user tabs to it (same as on mouse over). Found this post but can't seem to get it working
FIX: based on the answer provided by saratis
after
<table id="theGrid" class="scroll">
</table>
<div id="pager" class="scroll" style="text-align: center;">
</div>
add the following
<script type="text/javascript">
$(document).delegate('a', 'focus', function (event) {
$(this).removeClass('ui-state-hover'); //Remove previous hightlights
$(this).addClass('ui-state-hover');
});
$(document).delegate('a', 'focusout', function (event) {
$(this).removeClass('ui-state-hover'); //Remove previous hightlights
});
</script>
2.) When the user tabs between the fields on the add modal, would it be possible to keep the focus on the modal. eg that when tabbing, the focus only loops between the controls on the modal itself
3.) I'm experiencing a weird issue with the pager not being centered, and not sure what the fix is. I see that an attribute of 106px gets added to pager_left td which is causing it, gut its a generated value, so i'm not sure how to override/disable it
FIX: #pager_left{width:30%!important;}
Would it be possible to achieve any of this?
Thank you
First:
$('.yourInput').bind("mouseenter focus mouseleave",
function(event) {
$('.highlight').removeClass('highlight'); //Remove previous hightlights
$(this).addClass('highlight');
});
I have tried to add this to the fiddle, but I think the modal dialog is written dynamically to the DOM, so the binding should occur after its being placed. And I do not know how to integrate that. Sorry.
For the second part, can be done, but it would be easier when you povided a sample, or even better, as JSDFiddle. -> Looking at it now, I wouldn't know. I'm sure a JS jQuery Guru good do it, but this is too much for me. Again sorry.
Third:
Some good news, don't know the cause, but: #pager_left{width:150px!important;} does the trick.
Sorry I couldn't help more.
Use jQuery to check if any of the modal fields already have focus. If they do, trigger a function on keyup() that checks whether the tab button was pressed (its keycode is 9).
Use this to limit the tab indexing to your form.

I have zero experience in jQuery or js but I am trying to learn, so any help is much appreciated. I have a jQuery slide out (for live chat) that I would like to have slide out once a link is clicked. Ideally
Click Here
And this will make the chat slide out. The only code that is in the HTML is the onload
<body onload="initializeLiveHelp();">
You can see how it works here Link Fixed
If you need the jQuery I can get that as well but I was not sure if that was needed or not. Thank You
Try it by toggling the width. So write CSS for the closed state and use this jquery snippet to open it
Toggle width with jQuery
Add an ID to your link so
Click Here
becomes
Click Here
And the jquery something like this (but not exactly). Reference the SO thread for more info and check out the fiddle. Or post more HTML here and I can help further.
$(document).ready( function(){
$('#mylink').click( function() {
var toggleWidth = $("#toggle").width() == 300 ? "200px" : "300px";
$('#toggle').animate({ width: toggleWidth });
});
});
Trigger a click when someone clicks a link:
$("li a").on("click", function(event) {
event.preventDefault();
$(".livehelpslideout a").trigger("click");
}
Preventdefault() disables default behaviour when clicking on a link, otherwise browser will load another page. Your desired behaviour for that is unclear, so you'll need to think about your logic.
I'm doing a simple show/hide on a search form that uses jQuery's toggleClass() and CSS to show and hide the form. That's easy enough, something like:
$('#site-search-toggle').click(function(e){
$('#site-search').toggleClass('search-open');
e.preventDefault()
});
What I'd like to do but am having a hard time figuring out is to put focus on the search input when the form is shown and remove the focus from the search input when the form is hidden.
It's easy to add focus:
$('#site-search-toggle').click(function(e){
$('#site-search').toggleClass('search-open');
$('#site-search input[type="search"]').focus();
e.preventDefault()
});
But I'm stuck at how to remove it when $('#site-search-toggle') is clicked again to hide the form.
Just found this thread as I've been banging my head against this problem for a while now.
I've found a very simple way to do this, and essentially all you need to do is provide a click handler. When the element is clicked, you toggle the class which controls the 'focused' state, but you also programatically focus the element:
document.getElementById('myelement').addEventListener('click', function() {
this.classList.toggle('focus'); // or whatever...
this.focus();
});
You will need to give the element some sort of 'tabindex' value, probably 0 or -1.
And then, you provide a 'blur' handler, which just removes the 'focus' class whenver the user navigates away from the element.
document.getElementById('myelement').addEventListener('blur', function() {
this.classList.remove('focus');
return false;
});
Works like a dream!
I'm sorry that this is not a jQuery answer, but it should be easy enough to adapt - I just don't use it...

OK I figured this one out, or at least I found a way to do what I need to do. I added a second class, search-closed, toggled both classes, then used each class to focus or blur the field, something like this:
$('#site-search').addClass('search-closed');
$('.site-search__toggle').click(function(e){
// toggle both classes
$('#site-search').toggleClass('search-open search-closed');
// set focus when form is visible, .search-open
// use setTimeout to make sure the cursor actually gets in there
// don't know why, but it works
setTimeout (function(){
$('#site-search.search-open .site-search__input').focus();
}, 20);
// blur when the form is not visible, .search-closed
$('#site-search.search-closed .site-search__input').blur();
});
Try this:
$('#site-search-toggle').click(function(e){
$('#site-search').toggleClass('search-open');
if ($('#site-search').hasClass('search-open')) {
$('#site-search input[type="search"]').focus();
} else {
$('#site-search input[type="search"]').blur();
}
e.preventDefault();
});
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
Currenlty when a page is posting back or something else is going on I display a big grey div over the top of the whole page so that the user can't click the same button multiple times. This works fine 99% of the time, the other 1% is on certain mobile devices where the user can scroll/zoom away from the div.
Instead of trying to perfect the CSS so that it works correctly (this will be an on going battle with new devices) I've decided to just stop the user from being able to click anything. Something like $('a').click(function(e){e.preventDefault();}); would stop people from clicking anchor tags and navigating to the link but it wouldn't stop an onclick event in the link from firing.
I want to try to avoid changing the page too radically (like removing every onclick attribute) since the page will eventually have to be changed back to its original state. What I would like to do is intercept clicks before the onclick event is executed but I don't think that this is possible. What I do instead is hide the clicked element on mouse down and show it on mouseup of the document, this stops the click event firing but doesn't look very nice. Can anyone think of a better solution? If not then will this work on every device/browser?
var catchClickHandler = function(){
var $this = $(this);
$this.attr('data-orig-display', $this.css('display'));
$this.css({display:'none'});
};
var resetClickedElems = function(){
$('[data-orig-display]').each(function(){
$(this).css({display:$(this).attr('data-orig-display')}).removeAttr('data-orig-display');
});
};
$('#btn').click(function(){
$('a,input').on('mousedown',catchClickHandler);
$(document).on('mouseup', resetClickedElems);
setTimeout(function(){
$('a,input').off('mousedown',catchClickHandler);
$(document).off('mouseup', resetClickedElems);
}, 5000);
});
JSFiddle: http://jsfiddle.net/d4wzK/2/
You could use the jQuery BlockUI Plugin
http://www.malsup.com/jquery/block/
You can do something like this to prevent all actions of the anchor tags:
jQuery('#btn').click(function(){
jQuery('a').each(function() {
jQuery(this).attr('stopClick', jQuery(this).attr('onclick'))
.removeAttr('onclick')
.click(function(e) {
e.preventDefault();
});
});
});
That renames the onclick to stopclick if you need to revert later and also stops the default behavior of following the href.
document.addListener('click',function(e){e.preventDefault()})
Modified-
Its your duty to remove the click event from the document after you are done accomplishing with your task.
Eg -
function prevent(e){
e.preventDefault()
}
//add
document.addListener('click',prevent)
//remove
document.removeListener('click',prevent)
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.
