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.

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");
});
This tv.ui.button only responds to mouseclick when initially loaded, but then responds to keyboard ENTER or mouseclick after it's been clicked at least once. Do I have something wrong here?
HTML
<div class="tv-button alert-button" id="test-button">Alert button</div>
JS
decorateHandler.addClassHandler('alert-button', function(button) {
goog.events.listen(button, tv.ui.Button.EventType.ACTION,
function() {
alert('Button clicked.');
var elementToFocus = goog.dom.getElement('tab1');
var componentToFocus = tv.ui.getComponentByElement(elementToFocus);
tv.ui.Document.getInstance().setFocusedComponent(componentToFocus);;
});
});
EDIT: it seems this may be a question about javascript, not closure specifically. I'm posting a new question under the appropriate tag
Have you made sure that the button has cursor focus? If not then the "Enter" key event will get handed to the default handler.
Well, I fixed it with a semi hack. i used a $('target').click on the button within $(document).ready, which seems to set the focus as if a click event had actually happened
JScript
// Wait for the page and all the DOM to be fully loaded
$('body').ready(function() {
// Add the 'hover' event listener to our drop down class
$('.dropdown').hover(function() {
// When the event is triggered, grab the current element 'this' and
if ($(this).find('.sub_navigation').is(":visible")) {
// find it's children '.sub_navigation' and display/hide them
$(this).find('.sub_navigation').slideUp();
} else {
$(this).find('.sub_navigation').slideDown();
}
});
});
First of all here is the fiddle //

I am using wordpress to create my site...
(if that matters)
Someone helped me get the drop-down menu to work better.
But ever since I added the new JQuery script the link doesn't even work.
I tried hovering over it but no menu dropped.
When I hover on the fiddle it works.
Why is this?
And how can I fix this?! :(
I have a jQuery statement that's working fine. How would I re-write it in .live?
$(document).ready(function()
{
$(':input:enabled:visible, a:enabled:visible, span.ValidatorClass').each
(function(i, e) { $(e).attr('tabindex', i) });
});
The reason I need this is I hide/show elements sometimes using .show and .hide and when that happens I need to reset tab order for the elements that appear/disappear.
Showing and hiding elements raises no events as far as I know, so live won't help you here.
However, since you don't add new elements nor reorder them, you can set the correct tabindex right from the start. The browser will ignore hidden or disabled elements anyway. Run your code without the :visible and enabled filters:
$(':input, a, span.ValidatorClass')
.each(function(i, e) { $(e).attr('tabindex', i) });
