When using the JQueryUI dialog with the hide option added, the close event never fires. See my fiddle below to repro both ways.
Is there a workaround that I'm not aware of? I tried reordering them, but it didn't work. Any ideas?
http://jsfiddle.net/johntrepreneur/f4Ytr/3/
JAVASCRIPT (used for fiddle):
var $dialog = $('<div></div>').html('Using the hide dialog option ' +
'prevents the close event from firing. Clicking close does ' +
'nothing. Try commenting out the javascript line with the ' +
'hide effect to see the alert show up after clicking close.'
).dialog({
close: function () { alert('this will never show if hide option is active'); },
//hide: { effect: 'drop', direction: 'up' } //comment out to see alert show up
});
$dialog.dialog('open');
You're using jQuery UI 1.7.2 in your fiddle. If you replace it with the latest one (1.9.1 - //ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/jquery-ui.min.js) then your code works as expected. I don't know exactly what changed between those versions but there you go

so i'm working on a meteor project and am trying to get a drop down menu to close when the user clicks outside of it. i've done this before using jquery and normal html but this time we're using velocity.js and meteor.
so on the link that opens the drop down div, i have this:
Template.layout.events({
'click #profile-btn': function () {
if (userTog == false) {
$('#user-menu').velocity("fadeIn", { duration: 150 });
userTog = true;
}
else if (userTog == true) {
$('#user-menu').velocity("fadeOut", { duration: 150 });
userTog = false;
}
},
.....
and then i use a meteor package to deal with events on the body as this isnt supported right now..
Template.body.events({
'click html': function(e, data, tpl) {
userTog = false;
$('#user-menu').velocity("fadeOut", { duration: 150 });
e.stopPropagation();
}});
however the above is just not working.. it basically just makes the menu appear then disappear straight away. is it something to do with velocity.js, meteor or am i just doing it plain wrong ?!?
any advice would be greatly appreciated!
I just had to make a material design select box, so I feel your pain :-). Here's how I solved it:
Normally, you can only focus an input or an anchor. A trick I stumbled upon is that using tabindex="0" in your element attributes allows it to gain focus, even if it's a div. What's this mean? Well, if you can focus() an element, that means you can blur() it. So, when you click the button for the dropdown, add a line at the end of the event handler like $('.dropdown-menu').focus(). Then, to escape that, just create an event handler like 'blur .dropdown-menu': function() {*..hide..*}. That way, you don't have these ugly global event watchers.
The downside is that you get a glowing blue outline (for accessibility reasons). You can get rid of this by having a line like outline: 0; in your css.
PS, the reason why yours wasn't working is because 'click #profile-btn' bubbles up to the body, so it executes both. To fix it, you need to stop that bubblin via e.stopPropagation();.
I am using a CSS hover trick to clean up my interface. Controls will only be shown when the cursor is hovering inside the element. I'm running into an issue when using the interface on a touch screen device. If the control button is not shown display:none and I touch where it should be, the event is still triggered for the button.
Try this fiddle both in your browser and on a touchscreen device to see what I mean...
http://jsfiddle.net/6PvCn/2/
On a touchscreen device, touch the red square and the alert should fire, without the button even showing up. I tested this on both the desktop Android Emulator and my real Android 2.3 phone.
The effect I'm going for is for the button to first be shown without firing, even if the user touches where the button "is".
I'd rather use a pure CSS solution before resorting to javascript.
Try pointer-events: none; along with display: none;
I just tested it on my real device, and it indeed executes the button's action.
You could maybe try to make the red box an image and change the image to a button by an onclick with Javascript. I would have provided you with some code if I wasn't short on time.
You can't do it with pure CSS, tapping the button will put the button into hover state and fire the click event. Instead you should fire the button off on active.
Here is the solution I came up with... http://jsfiddle.net/6PvCn/7/
On an Android touchscreen (don't know about IOS), the hover event for the hidden element is not fired if it is not shown. So basically I check to see if the element was hovered before it was clicked.
In a nutshell
$(".hidden").hover(function(e) {
if(e.type == "mouseenter") $(this).addClass("hovering");
else $(this).removeClass("hovering");
}).click(function(e) {
if(!$(this).hasClass("hovering") return false;
});
The fiddle explains the more complicated situation I had with form elements and dynamically added content. It provides a general solution as opposed to this element specific one.
I wrote a JS solution for you:
https://codepen.io/anon/pen/bmYROr
The trick is to prevent the button's click event getting fired for the first time the outer div is getting clicked because on touch devices click event has hover effect.
let isTouchDevice = true;
let isHovered = false;
document.getElementById('outer').addEventListener('click', (e) => {
if (isTouchDevice) {
if (!isHovered) {
e.stopPropagation();
}
isHovered = true;
}
}, true);
document.getElementById('outer').addEventListener('mouseleave', (e) => {
if (isTouchDevice) {
isHovered = false;
}
}, true);
document.getElementById('btn').addEventListener('click', () => {
alert("hi");
});
I just found out that after upgrading to Meteor 0.5.2 (from 0.5) event handling for key events ('keypress', 'keydown', keyup') stopped working for me. Other events like ('click' & 'blur') work just fine.
Even in sample apps the code like this doesn't do anything:
Template.someTemplate.events = {
'keydown' : function(e) {
console.log(e);
}
};
The interesting thing is that this code does work (function fires) for keypresses in I'm typing inside an input type="text" or a textarea.
But elsewhere - nothing happens.
I'm testing on the latest Crome in Ubuntu 12.10.
Has anybody else experienced the issue?
Thanks,
George
The keydown event works for me for html that is editable. Input fields or contenteditable tags fire the keydown event.
But if you're asking how to handle keydown events on the body, this thread might help:
You can take a look at this thread: https://groups.google.com/forum/?fromgroups=#!topic/meteor-talk/uHy--xIGH8o.
Basically, for now, you can attach an event handler to the body element directly. In the example in the above link, he waits until the template is rendered, and then used jQuery to attach the handler:
Template.myTemplate.rendered = function() {
// Assuming you're using jQuery
$('body').on('keydown',function() {
console.log('key pressed');
});
}
The Meteor team is apparently going to include better support for attaching body level events soon.
You could have simply enclosed
$('body').on('keydown',function() {
console.log('key pressed');
});
in meteor.startup function
How to disable/enable a button? which is not in a form , in a navBar. I'v tried some examples , all fail.
I'm changing my textarea text $("textarea").val(x); The text is changing , the problem it doesn't get auto re-size , I see the ugly scroll bar on the side , If I manually resize it , its OK... is there a method to force refresh or something like that?
Thanks
Update (TextArea):
If i click on the text area and then press any key -> it opens up as should be,
I'm trying to simulate it .. but fail , the binding is works , but the trigger for keypress/keydown doesn't , I tried some codes from googling, this should work , I think , mayb for nomral jQuery 1.6 , but not jQuery mobile.. My test are are on Chrome and iPhone 4
$('#textarea').bind('click', function() {
var e = jQuery.Event("keypress", { keyCode: 64 });
$(this).trigger( e );
});
UPDATE:
Link button example:
http://jsfiddle.net/gRLYQ/6/
http://jsfiddle.net/gRLYQ/7/ (Header button example)
JS
var clicked = false;
$('#myButton').click(function() {
if(clicked === false) {
$(this).addClass('ui-disabled');
clicked = true;
alert('Button is now disabled');
}
});
$('#enableButton').click(function() {
$('#myButton').removeClass('ui-disabled');
clicked = false;
});
HTML
<div data-role="page" id="home">
<div data-role="content">
Click button
Enable button
</div>
</div>
NOTE: - http://jquerymobile.com/demos/1.0rc2/docs/buttons/buttons-types.html
Links styled like buttons have all the same visual options as true
form-based buttons below, but there are a few important differences.
Link-based buttons aren't part of the button plugin and only just use
the underlying buttonMarkup plugin to generate the button styles so
the form button methods (enable, disable, refresh) aren't supported.
If you need to disable a link-based button (or any element), it's
possible to apply the disabled class ui-disabled yourself with
JavaScript to achieve the same effect.
Regarding your second question, you can cause a textarea to autogrow by triggering a keyup() event on it.
Considering your original example code, the following works for me:
/*Note: I'm using 'on' instead of 'bind', because that's what I've actually tested
with, but I'm pretty sure this will work with 'bind' as well*/
$('#textarea').on('click', function() {
//First we'll add some text to #textarea
$('#textarea').val('some dummy text to be added to the textarea');
//Then we trigger keyup(), which causes the textarea to grow to fit the text
$('#textarea').keyup();
});
Short and sweet version of the above, this time chained and with no comments:
$('#textarea').on('click', function() {
$(this).val('some dummy text to be added to the textarea').keyup();
});
Adapted from here.
I am trying to set a focus on a dropdown within GridView(gridViewDropDown class) when page loads:
if ($('select.gridViewDropDown').length)
{
alert("Found my dropdown");
//$('select.gridViewDropDown:first').focus();
setTimeout(function() { $('select.gridViewDropDown').focus(); }, 10);
}
I can see the alert which means that dropdown is found but it never gets a focus. What do I need to change here? I am using IE 6/7.
I'd try this approach:
$(function() {
setTimeout(function() { $('select.gridViewDropDown').focus(); }, 50);
});
You need to wait until the DOM is ready, it's possible that something else is set to steal focus when the page loads (code that's most likely executing when the DOM's ready as well) This approach times it to be just slightly after that happens.
It also takes advantage of how jQuery works, if no elements are found when this function fires, none will steal focus, so it's safe to just leave in there as-is.
