I have 2 DIVs and in each DIV there's a Button which does something on click.
Now I've added a piece of code to bring the DIVs to front when they get a mousedown. Which works very well. The problem is, that they swallow the mousedown of the inner button... The inner button can only be clicked by double clicking it.
http://jsfiddle.net/nUtz6/
$('div').mousedown(function (event) {
$(this).parent().append($(this));
});
how could I solve this problem? I did it this way because I don't want to increment the z-index of the CSS property to some magic number everytime I click the div. I read that jquery also does the DOM manipulation trick.
The problem seems to occur because I change the DOM right before the click-Event of the button. If I don't do anything in the mousedown, everything works fine.
Just check that the DIV is actually the target of the event :
$('div').mousedown(function (event) {
if (event.target.tagName.toLowerCase() != 'button')
$(this).parent().append($(this));
});

Consider this code.
I cannot figure out why it behaves as it does. All I need is the play icon alternating with pause icon everytime I click anywhere inside the <td>. It behaves as expected when I click inside the <td> but outside the icon itself. However, if I click on the icon itself, it behaves fine the first time, and then stops.
'The ionicon is wrapped in the <a> tag, which is a child of the <td> element. The event listener is on the <td>, so what could be the problem?
Thanks.
As #Vijai said your problem with the hover event .. And While I don't know a lot about your project and you really need .empty() on hover or you just need to hide() the icon .. You can try this part of code instead of yours
var hovOn = function(event) {
if($(this).find('a').length < 1){
$(this).html(playButtonTemplate);
}else{
$(this).find('a').show();
}
};
var hovOff = function(event) {
$(this).find('a').hide();
}

Ok, figured it out. It seems like an artefact that arises from creating an element from a template and the way mouseenter is implemented.
The problem is that the mouseenter event (hoverOn part of the .hover()) triggers when it shouldn't. Each time a new ionicon is created from a template it will trigger the mouseenter event if the cursor moves a little.
Logically mouseenter shouldn't be triggered when the element appears, because mouseenter should trigger when a listener element or its descendent is hovered over, and then only call when the cursor leaves all of the elements associated with the event and then enters again. I think this is an artefact of creating an element from a template like that. Maybe it's because DOM get updated and it discards the fact that the cursor is already within the element. So mouseenter triggers again and in turn triggers creating a new play icon. Then it repeats..
This codepen should explain it well. If you hover over the play button the mouseenter counter will increment each time you move your mouse even a little, because each time a mouse is moved, a new play button is created. If you delete the line that creates a new play button, it behaves as mouseenter should, triggering only when the cursor enters the element.
When you click on the <a> tag it seems it is also triggering the parent <td> hover event. Once solution is try the below code for hover.
var hovOn = function(event) {
if(playOrPause==='play') {
$(this).html(pauseButtonTemplate);
playOrPause = 'pause';
} else {
$(this).html(playButtonTemplate);
playOrPause = 'play';
}
};
I have this code:
document.getElementById("1").oncontextmenu = function() {
return false
}
It disables the little window that shows after a right click (only on the button/image).
On my code (https://jsfiddle.net/nnuyguat/) everything is working fine, except for when I do a right click on the image as it triggers the left click event and changes the image untill I move the mouse.
Another related problem is if I press left click without releasing and then right click (releasing the right button), it will also change the image.
I need to prevent the image changing with right clicks. It should work as the closing button of the browser (except it's another images and it doesn't close anything).
You could use event.button to check which button is pressed because event.button returns a number which indicates which mouse button was pressed.

Edit:
if (event.button === 2){
// run your function
}
That should be correct, as I have never used this before.
The right click event is not triggering a left click. It is just activating your object. Your image says "click" but it is inaccurate. It should say "Active".
Second, a number is NOT a valid ID. So rename your div from id="1" to id="one" or similar.
Finally, try with this code, instead of yours:
document.getElementById("one").addEventListener('contextmenu', function(ev) {
ev.preventDefault();
alert('hello from right click');
return false;
}, false);
See https://jsfiddle.net/nnuyguat/3/
The issue with your image changing on right click is not related to your javascript, but to your css. The :active CSS pseudo-class matches when an element is being activated by the user. According to the specs this should only be when the element is activated with the primary mouse button, but it seems like most browsers do not implement the spec correctly. See this question for info.
A work around maybe to abandon the :active pseudo-class, and set up a function to change the content explicitly on left click.
Its because of the oncontextmenu event. Remove it and it will work
So I have this code here.
timeline.afterMilestonePrototypeCreated = function() {
$(MILESTONE_PROTOTYPE_SELECTOR).hover(function(e){
$(this).find('textarea').focus();
});
}
Which should focus the textarea element after it was created. Everything works fine, I've even checked if the event is being called, after creation and hovering. Every other code works, but I'm not able to focus that textarea element. After some googling I've tried to add a setTimeout, which didn't work neither.
Thanks!
SOLVED:
The parent element of the textarea is a dot, and after hovering the dot it becomes a bigger circle and than it's inner elements are becoming visible. The problem was, that when adding the timeout the duration I've set was to short so the css transition for making the textarea visible was still going that's way it wasn't focusing.
Instead of this:
$(this).find('textarea').focus();
Try this:
$(e.target).find('textarea').focus();
This may work, as long as $(this).find('textarea') works as expected:
timeline.afterMilestonePrototypeCreated = function() {
$(MILESTONE_PROTOTYPE_SELECTOR).hover(function(e){
e.preventDefault();
$(this).find('textarea').focus();
});
}
A hover event triggers a focus event, so preventing it will allow the manual focus to occur.
I'm trying to build some kind of element inspector (like in Chrome/FF).
Flow is as follows:
You click 'Start inspecting' button.
You hover over necessary element.
You click on that element.
You should see that element in console.
JSFiddle example
Here is the code:
startInspecting = function(){
$('section *').on('mouseover.INSPECTOR', function(e){
$('.hovered-element').removeClass('hovered-element');
$(e.target).addClass('hovered-element');
$(this).on('click.INSPECTOR', function(e){
$('section *').off('mouseover.INSPECTOR');
$('section *').off('click.INSPECTOR');
$('.hovered-element').removeClass("hovered-element");
console.log(e.target);
});
});
};
The problem is: each time I hover over some element - click event handler is attached to it. So if I hover over p element 5 times, and then click on it - I will see 5 console.logs instead of 1.
I tried to implement it using mouseenter/mouseleave, but faced the issue, that each element can be hovered only once - another JSFiddle example
So how can I improve my code that no matter how many times I hover over the element, it will have only one click handler?
Thanks in advance, any help will be appreciated!
Did you try moving the onclick handler outside the mouseover?
startInspecting = function(){
$('section *').on('mouseover.INSPECTOR', function(e){
$('.hovered-element').removeClass('hovered-element');
$(e.target).addClass('hovered-element');
}).on('click.INSPECTOR', function (e) {
$('section *').off('mouseover.INSPECTOR click.INSPECTOR');
console.log(e.target);
});
};
DEMO
I'd suggest breaking it up into parts. The user clicks on "Start Inspecting" and your page goes into inspecting mode where it adds css dynamically to every element that is hovered over so it looks similar to Chrome. When you click on an element in inspecting mode then you can handle it how you want. This way you only have to add one hover and one click handler per element, thus only triggering the event once.
I have a slideshow that has 5 slides (each has an individual id) and a previous and next button. When hovering the previous or next button you get a tooltip, the tooltip uses jQuery to get the ID attribute from the previous and next div and show this.
Ive gotten it working fine on mouseenter only if you dont leave the div and keep clicking the Tooltip doesnt update, you have to leave the arrows after each click for the value to be aupdated, does this make sense?
my script is...
$("div.arrows div").bind("mouseenter", function () {
$("div.arrows div.next").children("span").html($("div.roundabout-in-focus").next("div").attr("id"));
$("div.arrows div.prev").children("span").html($("div.roundabout-in-focus").prev("div").attr("id"));
});
Since you are not leaving the div the next mouseenter is not fired which will update the tooltip. Try to set the tooltip on slide change event if supported by the plugin you are using or click event of the prev/next buttons.
You will have to bind the updated html to the click event also then. This may work. Hard to tell without your html.
$("div.arrows div").bind("click, mouseenter", function () {
$("div.arrows div.next").children("span").html($("div.roundabout-in-focus").next("div").attr("id"));
$("div.arrows div.prev").children("span").html($("div.roundabout-in-focus").prev("div").attr("id"));
});
What does mouseover do and do you want it to change after a click on the next/prev button? I think you have to remove the inner HTML before appending new HTML. Maybe try to empty the element with .empty() and add a click event to catch that and call the function from there as well. Also try to log or alert some feedback to know when it does fire.
