I've been implementing a drop menu in javascript, and I'm finding it difficult to understand why the event bubbling system is implemented as it is. In summary, I want an event to occur when the mouse enters/exits a large div or table that contains many descendent elements.
It appears to me, from experimenting with IE6 and Moz 5, that the event is generated *only* on the lowest element, thus given a table which contains tbody, tr and tds, with an onmouseover listener assigned to the table element (as a property), the onmouseover event is generated only for the td, although the mouse actually entered all these elements.
If there is a slight gap between elements you sometimes get events for the higher element. I guess this is a side-effect of the browser's implementation - sampling the mouse position.
My understanding of event bubbling from "JavaScript the definitive guide" is that events should bubble up the heirarchy unless they are stopped by the stopPropagation() method.
have a small div above (hover) a big one. I assign onmouseover and onmouseout events to the wrapper div. For image caption roll-over animation. The problem is when the mouse is above the caption itself, causing an unwanted result(probably event bubbling).
And another problem: sometimes when you move mouse from outside to container you get a a triple debug sequence: (it should be just 2): -I am over- -I am out- -I am over- (firebug console) How to make it work? (no jquery) must work on all browsers.[URL]... The wanted result: When mouse moved over the image, only mouseover event should be raised once When mouse moved out from the image, only the mouseout event should be raised. when mouse is over the captionm it should be treated as if the mouse is still on the image. (no flickering)
The objective is to create a stacked, inline vertical menu. Upon mousing over a menu option, a series of sublinks (children) presents itself immediately beneath the parent. The children push the rest of the menu options downward. We're ok up to this point.
Should the mouse pointer point to another menu option, the children of the former menu option pointed at disappear and the new children are displayed. We're still ok. Here's the code I use to accomplish this: Code:
I'm working on a couple of pages that look like this: [URL] As the visitor mouses over the month name, the image to the right is supposed to change to show the cover of that month's magazine issue. The onmouseover/onmouseout code has been working fine for months, but I recently added a couple new JS elements to the page, and now when the visit stops hovering over Sep/Oct, the image doesn't change.
I'm thinking that the way to fix this is by converting this action to jQuery, which is loaded on the page anyway, but I'm struggling to get a concise expression of what I want to happen. That is, I can do it by brute force with dozens of lines of code, but there must be a better way.
How can I add an onMouseout event to this code? I have only used this script with the onClick enent. If there is a simpler way, please let me know that. Code:
This is probably very simple but I really cant find the answer. I have a text box, and I am wanting the same mouseover and onclick functionality as Money Supermarket; [URL]... When I rollover the text box/table row then I want the area to display one colour and when I roll off then it goes back to normal. However, when I click on it I also want it to display the colour and remain that way until I click another element. How do I achieve this?
I'm using code below to run a function when the user move the mousepointer from within a DIV and outside it:The idea is that that mousepointer motion shall hide the DIV.
Code:
document.getElementById(theID).onmouseout = hideDiv; if (document.getElementById(theID).captureEvents) document.getElementById(theID).captureEvents(Event.MOUSEOUT);
It kind of works, but the problem is that if I move the mousepointer to fast out of the DIV then it will not trigger.The div in question has some elements within it, and originally it was allmost fully covered by those element... and then the onmouseout did not work that good....So I had to create some padding for the div to make it detect the onmouseout better... kind of work... but sometimes failes to trigger on the onmouseout.That padding also make the div not look that good ... so would like to get rid of all the padding as well, and make it work, if possible.I have tested this in the following browsers and get pretty much same behaviour in them all:IE8, Firefox (latest), Chrome (latest), Safari for win (latest beta)...
I am trying to build my first interface using jQuery. I will have some icons on the page. When user hovers the mouse on an image, it should display a list of menu options (some more icons). Like:
I have a menu with a div displaying onmouseover, and hiding onmouseout, it works great except in IE if I click on the <select> tag, it triggers the mouseout event, interestingly enough the same does not happen when I click on a text field..
Code Example:
This is obviously not the real code, it's just to give you an idea, I don't think I can post the real code, cuz it's really long and complicated...
I'm using the prototype framework, and I'd like to keep it that way if possible...
I'm having a problem with .attr(). I will explain it whith code.I have this HTML code:
<p id="textoMarca0" onmouseover="muestraDialog('textoMarca0');"> this is an example paragraph </p>
[code]....
So now the onmouseover has again its value [the original one, copied by doing an alert($("#"+elem+i).attr('onmouseover')) when i disable the onmouseover event], but it doesn't work
Wanting to have a table cell select it's contained radiobutton in a rather non-specific way, I wrote the following javascript:
function click_it(element) { var x = element.childNodes
for(var i=0;i<x.length;x++) { var tag = x[i]; if(!tag.tagName || tag.tagName != "INPUT") continue;
tag.checked = !tag.checked; }}
It works fine for clicking the table cell and selecting contained radiobuttons. However, when actually clicking the radiobutton, the browser decides (correctly) to first fire the internal radiobutton click event, thus selecting the radiobutton - and THEN fireing the click handler for my table cell, thus de-selecting it again :-P If this was to only work for radiobuttons, I could easily make it do "tag.checked = 1" every time, but it needs to work for checkboxes too, so the de-select should work too (if checked).
I am trying to organise some code on a large project I'm doing which changes a lot of code around the page with submit forms. As jQuery doesn't have a live support for submit elements I thought I'd try my hand at event bubbling. It works nicely in firefox but isn't working at all in IE.
[code] $('#data').submit( function(e) { /* When a edit form is selected */ if (e.target.className == 'edit_link'){ //ajax request }}); [/code]
I have a div with an id #data inside this div is a table with data and forms at the end of each of the row to edit parameters. When I click edit it loads a form in another div outside the #data one via ajax then the user can change the values and hit update (which has a class of .edit_link ) at which point it should reload the #data div. The reloading of the #data div is why I need some sort of live event to it. I've tried doing the way above and it works great in firefox but not in IE. Just to clarify the submit doesn't fire at all.
building a tree using UL,LI tags as below. Issue seems with cancelling event bubbling. trying to cancel dragenter event to avoid dragenter firing for root LI. dragenter on image cancels bubbling. But dragenter on the child text bubbles and fires for Root. Whole purpose is to identify LI where its dropped. Edit: Noticed this is working as expected in IE6 and not working with IE8.
I just want to understand the concept of event bubbling, capturing and delegation. I have read a lot about them but still unable to fully understand them (capturing, bubbling, delegation).
I'm in the process of integrating the google maps api into my application. Unfortunately, my events seem to be bubbling. If I open the google maps info window 3 times and click the next button respectively, on the forth time when I click the next button the next event will fire four times. How do I stop this?
currently on our site we have and expanding <div> that responds to both the onmouseover and onmouseout events. It works wonderfully.
The UX people now would like the expanding <div> to open with the onclick event and then as soon as the mouse leaves the expanded div, it would close. I have tried using the onmouseout event in conjunction the onclick event but it does not work (the div persists).
I have a<button>element inside of which I have 2<span>elements. I have 2 attached jquery click event handlers for each of the span elements so I can do whatever I like for each click. This is all working fine in Chrome and the click event is captured in the correct order: first on any of the span elements and then the event bubbles up to the parent button element. The problem is that in Firefox the click event does not fire for any of the span elements, just the button event handler logs the event as being fired.[URL]..
I'mtryingto put the right code in place to stop event bubbling on my menu script. I have a the following code for the mouseenter event. I can't find where's appropraite to put stopPropagation()
menu_trigger is an array which is cycled through to put the mouseenter event onto the right <th> tags menu_objects is an array linking to the menu which should be shown.
im having trouble using JQUERYs animate function. Basicly the div has a mouseover event that slides another div (that is inside the original div) upwards. The first div has a mouseout event that slides the second div downwards and out of view. The problem being that when you hover over the second div it fires the first divs mouseout event. Ive tried googling this and have tried adding some event bubbling but having serious trouble with it. here is the website... [URL] hover over the image and you should see the caption appear, roll over the caption and it goes crazy.
I have a TD element, with a SPAN element inside. I use td-s onmouseover and onmouseout events for a small animation. My problem is, that, when I move the cursor over the SPAN element, the onmouseout event for TD element is fired. I want to prevent this. With other words, I want onmouseout fired, just when the cursor is moved outside the td area. See the code..
I have a table with two columns and two rows in it. In the upper left corner, I have a logo image for my company. In the top right column/cell, I have some navigational stuff, no big deal. In the left cell in the 2nd row, I have a list of anchors of different songs I am producing - something like this:
The cell on the right, 2nd row is empty at the start.
On the 2nd row, 1st cell, where the anchors are, on a "mouse over" event, I'd like to display song lyrics and information regarding the song in the right cell, 2nd row as the user moves the mouse over a given anchor.
What is the best way for me to do this? There are a couple of things/issues I can think of right away:
1) Let's say there are 20 anchors in the left column. Let's say that some of the songs' lyrics are quite lengthy and extend past the height of the cell at row 2, left column. How would the system know this in advance (this will make more sense with question #2 below)? Perhaps tell it some type of maximum height you know will never be reached or something?
2) To me it doesn't make a lot of sense to include all this text in the main HTML file since a majority of the time, the user(s) will never move their mouse across ALL the anchors, only one or two. Seems to me there should be some way of "loading" them as soon as the mouse over event occurs.
