Is there a way to change the link color to gray without the code glitching like at my site.
(code glitches and says Quick Nav. )
Click here to see page with glitch
I only want that link to be bold not the other.
Heres the current code.
<script type="text/javascript">
// Popup window code
function newPopup(url) {
popupWindow = window.open(
url,'popUpWindow','height=700,width=800,left=10,top=10,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no,status=yes')
}
</script>
<a style="text-decoration:none;" href="JavaScript:newPopup('<font color="gray">http://onlythebestoftheweb.x10.mx/navigation/quick.html</font>');">Quick Nav.</a>
Also just to let you know the page is supposed to be a 404 error, thats where the glitch is.
Since you're using CSS, you'd want to just take that link for the popup, give it a class name, and style the class name with the CSS.
Add these lines of CSS
CSS:
a.popup-link {
color: grey;
text-decoration: none;
}
Then change the link for the popup to the following:
HTML:
<a class="popup-link" href="JavaScript:newPopup('http://onlythebestoftheweb.x10.mx/navigation/quick.html');">Quick Nav.</a>
For changing the link color to gray:
CSS:
a {
color: #848484;
}
The reason your code is "glitching" is because of this line:
<a style="text-decoration:none;" href="JavaScript:newPopup('<font color="gray">http://onlythebestoftheweb.x10.mx/navigation/quick.html</font>');">Quick Nav.</a>
You need to escape double quotes within double quotes to make it work:
<a style="text-decoration:none;" href="JavaScript:newPopup('<font color=\"gray\">http://onlythebestoftheweb.x10.mx/navigation/quick.html</font>');">Quick Nav.</a>
Here you go, this is a little cleaner practice.

I've spent the better part of a day tracking down a problem I've been having with jQuery animation. There appear to be issues with applying jQuery.animate() to anchor elements, or to child elements inside of anchor elements, at least with regard to movement animations. I've boiled the problem down to a fairly simple example which illustrates the problem:
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js"></script>
<script>
var foo = {};
function TestMove(newx, newy) {
this.newx = newx;
this.newy = newy;
}
TestMove.prototype = {
movex:function () {
$("#newsec").animate({left: this.newx + "px"});
},
movey:function () {
$("#newsec").animate({top: this.newy + "px"});
}
}
function bar() {
foo[1].movex();
foo[1].movey();
}
function init() {
foo[1] = new TestMove(200,200);
}
</script>
</head>
<body onload="init()">
<a href="" style="position: relative;">
<div style="position: relative; height: 50px; width: 50px; background-color: red;" id="newsec" onclick="bar()"></div>
</a>
</body>
</html>
The animation doesn't work, regardless of whether I put the id attribute and onclick event handler call in the <a> tag or in the <div> within it. If, on the other hand,I remove the <a> element tags altogether, the animation works as expected on the <div> element.
Does anyone have any idea why this happens?
The issue is almost moot, since I can easily do with <div> elements in the working page what I could also do with <a> elements. In the working code (much more complex) I'm using event.preventDefault() on the anchor elements so that linking and other actions are driven by explicit event handlers and this can be done from a <div> just as well. I believe I can even change the pointer icon when one does a mouseover on the <div> so that it mimics a true anchor in this regard as well.
It's because the browser is going to the anchor prior to the animation being put in place. There are plugins to get around these sort of issues, or you can put together your own.
http://briangonzalez.org/arbitrary-anchor
Example of a simple implementation:
jQuery.fn.anchorAnimate = function(settings) {
settings = jQuery.extend({
speed : 1100
}, settings);
return this.each(function(){
var caller = this
$(caller).click(function (event) {
event.preventDefault()
var locationHref = window.location.href
var elementClick = $(caller).attr("href")
var destination = $(elementClick).offset().top;
$("html:not(:animated),body:not(:animated)").animate({ scrollTop: destination}, settings.speed, function() {
window.location.hash = elementClick
});
return false;
})
})
}
I am having trouble with the onmouseout function in an absolute positoned div. When the mouse hits a child element in the div, the mouseout event fires, but I do not want it to fire until the mouse is out of the parent, absolute div.
How can I prevent the mouseout event from firing when it hits a child element WITHOUT jquery.
I know this has something to do with event bubbling, but I am having no luck on finding out how to work this out.
I found a similar post here: How to disable mouseout events triggered by child elements?
However that solution uses jQuery.
Use onmouseleave.
Or, in jQuery, use mouseleave()
It is the exact thing you are looking for. Example:
<div class="outer" onmouseleave="yourFunction()">
<div class="inner">
</div>
</div>
or, in jQuery:
$(".outer").mouseleave(function(){
//your code here
});
an example is here.
For a simpler pure CSS solution that works in most cases, one could remove children's pointer-events by setting them to none
.parent * {
pointer-events: none;
}
Browser support: IE11+
function onMouseOut(event) {
//this is the original element the event handler was assigned to
var e = event.toElement || event.relatedTarget;
if (e.parentNode == this || e == this) {
return;
}
alert('MouseOut');
// handle mouse event here!
}
document.getElementById('parent').addEventListener('mouseout',onMouseOut,true);
I made a quick JsFiddle demo, with all the CSS and HTML needed, check it out...
EDIT FIXED link for cross-browser support http://jsfiddle.net/RH3tA/9/
NOTE that this only checks the immediate parent, if the parent div had nested children then you have to somehow traverse through the elements parents looking for the "Orginal element"
EDIT example for nested children
EDIT Fixed for hopefully cross-browser
function makeMouseOutFn(elem){
var list = traverseChildren(elem);
return function onMouseOut(event) {
var e = event.toElement || event.relatedTarget;
if (!!~list.indexOf(e)) {
return;
}
alert('MouseOut');
// handle mouse event here!
};
}
//using closure to cache all child elements
var parent = document.getElementById("parent");
parent.addEventListener('mouseout',makeMouseOutFn(parent),true);
//quick and dirty DFS children traversal,
function traverseChildren(elem){
var children = [];
var q = [];
q.push(elem);
while (q.length > 0) {
var elem = q.pop();
children.push(elem);
pushAll(elem.children);
}
function pushAll(elemArray){
for(var i=0; i < elemArray.length; i++) {
q.push(elemArray[i]);
}
}
return children;
}
And a new JSFiddle, EDIT updated link
instead of onmouseout use onmouseleave.
You haven't showed to us your specific code so I cannot show you on your specific example how to do it.
But it is very simple: just replace onmouseout with onmouseleave.
That's all :) So, simple :)
If not sure how to do it, see explanation on:
https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_onmousemove_leave_out
Peace of cake :) Enjoy it :)
Here's a more elegant solution based on what came below.
it accounts for event bubbling up from more than one level of children.
It also accounts for cross-browser issues.
function onMouseOut(this, event) {
//this is the original element the event handler was assigned to
var e = event.toElement || event.relatedTarget;
//check for all children levels (checking from bottom up)
while(e && e.parentNode && e.parentNode != window) {
if (e.parentNode == this|| e == this) {
if(e.preventDefault) e.preventDefault();
return false;
}
e = e.parentNode;
}
//Do something u need here
}
document.getElementById('parent').addEventListener('mouseout',onMouseOut,true);
Thanks to Amjad Masad that inspired me.
I've the following solution which seems to work in IE9, FF and Chrome and the code is quite short (without the complex closure and transverse child things) :
DIV.onmouseout=function(e){
// check and loop relatedTarget.parentNode
// ignore event triggered mouse overing any child element or leaving itself
var obj=e.relatedTarget;
while(obj!=null){
if(obj==this){
return;
}
obj=obj.parentNode;
}
// now perform the actual action you want to do only when mouse is leaving the DIV
}
If you're using jQuery you can also use the "mouseleave" function, which deals with all of this for you.
$('#thetargetdiv').mouseenter(do_something);
$('#thetargetdiv').mouseleave(do_something_else);
do_something will fire when the mouse enters thetargetdiv or any of its children, do_something_else will only fire when the mouse leaves thetargetdiv and any of its children.
I think Quirksmode has all the answers you need (different browsers bubbling behaviour and the mouseenter/mouseleave events), but I think the most common conclusion to that event bubbling mess is the use of a framework like JQuery or Mootools (which has the mouseenter and mouseleave events, which are exactly what you intuited would happen).
Have a look at how they do it, if you want, do it yourself
or you can create your custom "lean mean" version of Mootools with just the event part (and its dependencies).
Try mouseleave()
Example :
<div id="parent" mouseleave="function">
<div id="child">
</div>
</div>
;)
I've found a very simple solution,
just use the onmouseleave="myfunc()" event than the onmousout="myfunc()" event
In my code it worked!!
Example:
<html>
<head>
<script type="text/javascript">
function myFunc(){
document.getElementById('hide_div').style.display = 'none';
}
function ShowFunc(){
document.getElementById('hide_div').style.display = 'block';
}
</script>
</head>
<body>
<div onmouseleave="myFunc()" style='border:double;width:50%;height:50%;position:absolute;top:25%;left:25%;'>
Hover mouse here
<div id='child_div' style='border:solid;width:25%;height:25%;position:absolute;top:10%;left:10%;'>
CHILD <br/> It doesn't fires if you hover mouse over this child_div
</div>
</div>
<div id="hide_div" >TEXT</div>
Show "TEXT"
</body>
</html>
Same Example with mouseout function:
<html>
<head>
<script type="text/javascript">
function myFunc(){
document.getElementById('hide_div').style.display = 'none';
}
function ShowFunc(){
document.getElementById('hide_div').style.display = 'block';
}
</script>
</head>
<body>
<div onmouseout="myFunc()" style='border:double;width:50%;height:50%;position:absolute;top:25%;left:25%;'>
Hover mouse here
<div id='child_div' style='border:solid;width:25%;height:25%;position:absolute;top:10%;left:10%;'>
CHILD <br/> It fires if you hover mouse over this child_div
</div>
</div>
<div id="hide_div">TEXT</div>
Show "TEXT"
</body>
</html>
Hope it helps :)
Although the solution you referred to uses jquery,
mouseenter and mouseleave are native dom events, so you might use without jquery.
There are two ways to handle this.
1) Check the event.target result in your callback to see if it matches your parent div
var g_ParentDiv;
function OnMouseOut(event) {
if (event.target != g_ParentDiv) {
return;
}
// handle mouse event here!
};
window.onload = function() {
g_ParentDiv = document.getElementById("parentdiv");
g_ParentDiv.onmouseout = OnMouseOut;
};
<div id="parentdiv">
<img src="childimage.jpg" id="childimg" />
</div>
2) Or use event capturing and call event.stopPropagation in the callback function
var g_ParentDiv;
function OnMouseOut(event) {
event.stopPropagation(); // don't let the event recurse into children
// handle mouse event here!
};
window.onload = function() {
g_ParentDiv = document.getElementById("parentdiv");
g_ParentDiv.addEventListener("mouseout", OnMouseOut, true); // pass true to enable event capturing so parent gets event callback before children
};
<div id="parentdiv">
<img src="childimage.jpg" id="childimg" />
</div>
simply we can check e.relatedTarget has child class and if true return the function.
if ($(e.relatedTarget).hasClass("ctrl-btn")){
return;
}
this is code worked for me, i used for html5 video play,pause button toggle hover video element
element.on("mouseover mouseout", function(e) {
if(e.type === "mouseout"){
if ($(e.relatedTarget).hasClass("child-class")){
return;
}
}
});
I make it work like a charm with this:
function HideLayer(theEvent){
var MyDiv=document.getElementById('MyDiv');
if(MyDiv==(!theEvent?window.event:theEvent.target)){
MyDiv.style.display='none';
}
}
Ah, and MyDiv tag is like this:
<div id="MyDiv" onmouseout="JavaScript: HideLayer(event);">
<!-- Here whatever divs, inputs, links, images, anything you want... -->
<div>
This way, when onmouseout goes to a child, grand-child, etc... the style.display='none' is not executed; but when onmouseout goes out of MyDiv it runs.
So no need to stop propagation, use timers, etc...
Thanks for examples, i could make this code from them.
Hope this helps someone.
Also can be improved like this:
function HideLayer(theLayer,theEvent){
if(theLayer==(!theEvent?window.event:theEvent.target)){
theLayer.style.display='none';
}
}
And then the DIVs tags like this:
<div onmouseout="JavaScript: HideLayer(this,event);">
<!-- Here whatever divs, inputs, links, images, anything you want... -->
<div>
So more general, not only for one div and no need to add id="..." on each layer.
If you have access to the element which the event is attached to inside the mouseout method, you can use contains() to see if the event.relatedTarget is a child element or not.
As event.relatedTarget is the element to which the mouse has passed into, if it isn't a child element, you have moused out of the element.
div.onmouseout = function (event) {
if (!div.contains(event.relatedTarget)) {
// moused out of div
}
}
On Angular 5, 6 and 7
<div (mouseout)="onMouseOut($event)"
(mouseenter)="onMouseEnter($event)"></div>
Then on
import {Component,Renderer2} from '#angular/core';
...
#Component({
selector: 'app-test',
templateUrl: './test.component.html',
styleUrls: ['./test.component.scss']
})
export class TestComponent implements OnInit, OnDestroy {
...
public targetElement: HTMLElement;
constructor(private _renderer: Renderer2) {
}
ngOnInit(): void {
}
ngOnDestroy(): void {
//Maybe reset the targetElement
}
public onMouseEnter(event): void {
this.targetElement = event.target || event.srcElement;
console.log('Mouse Enter', this.targetElement);
}
public onMouseOut(event): void {
const elementRelated = event.toElement || event.relatedTarget;
if (this.targetElement.contains(elementRelated)) {
return;
}
console.log('Mouse Out');
}
}
I check the original element's offset to get the page coordinates of the element's bounds, then make sure the mouseout action is only triggered when the mouseout is out of those bounds. Dirty but it works.
$(el).live('mouseout', function(event){
while(checkPosition(this, event)){
console.log("mouseovering including children")
}
console.log("moused out of the whole")
})
var checkPosition = function(el, event){
var position = $(el).offset()
var height = $(el).height()
var width = $(el).width()
if (event.pageY > position.top
|| event.pageY < (position.top + height)
|| event.pageX > position.left
|| event.pageX < (position.left + width)){
return true
}
}
var elem = $('#some-id');
elem.mouseover(function () {
// Some code here
}).mouseout(function (event) {
var e = event.toElement || event.relatedTarget;
if (elem.has(e).length > 0) return;
// Some code here
});
If you added (or have) a CSS class or id to the parent element, then you can do something like this:
<div id="parent">
<div>
</div>
</div>
JavaScript:
document.getElementById("parent").onmouseout = function(e) {
e = e ? e : window.event //For IE
if(e.target.id == "parent") {
//Do your stuff
}
}
So stuff only gets executed when the event is on the parent div.
I just wanted to share something with you.
I got some hard time with ng-mouseenter and ng-mouseleave events.
The case study:
I created a floating navigation menu which is toggle when the cursor is over an icon.
This menu was on top of each page.
To handle show/hide on the menu, I toggle a class.
ng-class="{down: vm.isHover}"
To toggle vm.isHover, I use the ng mouse events.
ng-mouseenter="vm.isHover = true"
ng-mouseleave="vm.isHover = false"
For now, everything was fine and worked as expected.
The solution is clean and simple.
The incoming problem:
In a specific view, I have a list of elements.
I added an action panel when the cursor is over an element of the list.
I used the same code as above to handle the behavior.
The problem:
I figured out when my cursor is on the floating navigation menu and also on the top of an element, there is a conflict between each other.
The action panel showed up and the floating navigation was hide.
The thing is that even if the cursor is over the floating navigation menu, the list element ng-mouseenter is triggered.
It makes no sense to me, because I would expect an automatic break of the mouse propagation events.
I must say that I was disappointed and I spend some time to find out that problem.
First thoughts:
I tried to use these :
$event.stopPropagation()
$event.stopImmediatePropagation()
I combined a lot of ng pointer events (mousemove, mouveover, ...) but none help me.
CSS solution:
I found the solution with a simple css property that I use more and more:
pointer-events: none;
Basically, I use it like that (on my list elements):
ng-style="{'pointer-events': vm.isHover ? 'none' : ''}"
With this tricky one, the ng-mouse events will no longer be triggered and my floating navigation menu will no longer close himself when the cursor is over it and over an element from the list.
To go further:
As you may expect, this solution works but I don't like it.
We do not control our events and it is bad.
Plus, you must have an access to the vm.isHover scope to achieve that and it may not be possible or possible but dirty in some way or another.
I could make a fiddle if someone want to look.
Nevertheless, I don't have another solution...
It's a long story and I can't give you a potato so please forgive me my friend.
Anyway, pointer-events: none is life, so remember it.
There are a simple way to make it work. The element and all childs you set a same class name, then:
element.onmouseover = function(event){
if (event.target.className == "name"){
/*code*/
}
}
Also for vanillajs you can use that way
document.querySelector('.product_items') && document.querySelector('.product_items').addEventListener('mouseleave', () => updateCart())
const updateCart = () => {
let total = 0;
document.querySelectorAll('input') && document.querySelectorAll('input').forEach(item => total += +item.value)
document.getElementById('total').innerHTML = total
}
<div class="product_items">
<div class="product_item">
<div class="product_name">
</div>
<div class="multiply__btn">
<button type="button">-</button>
<input name="test" type="text">
<button type="button">+</button>
</div>
</div>
<div class="product_item">
<div class="product_name">
</div>
<div class="multiply__btn">
<button type="button">-</button>
<input name="test" type="text">
<button type="button">+</button>
</div>
</div>
<div class="product_item">
<div class="product_name">
</div>
<div class="multiply__btn">
<button type="button">-</button>
<input name="test" type="text">
<button type="button">+</button>
</div>
</div>
</div>
<div id="total"></div>
If for some reason you don't want to use the mouseenter and mouseleave events, you can use mouseover/mouseout with a little "debouncing".
The idea relies on the fact that your event handler will receive out followed by a new over when crossing boundaries between various child elements....except when the mouse has really left (for longer than the debounce period). This seems simpler than crawling the dom nodes on every event.
If you "debounce" with a short delay before assuming you have a real out you can effectively ignore all these out/over events bubbling up from child elements.
Note! This will not work if a child element also has a listener for over and/or out events AND their handler calls event.stopPropogation() to stop the event from bubbling up to the parent element where we have attached our handler. If you control the code, this is not necessarily a problem, but you should be aware.
sample code
javascript
function mouseOverOutDebounce (element, debounceMs, mouseOverFn, mouseOutFn) {
var over = false,
debounceTimers = [];
function mouseOver (evt) {
if (over) { // already OVER, existing interaction
while (debounceTimers.length > 0) { // then we had a pending mouseout(s), cancel
window.clearTimeout(debounceTimers.shift());
}
}
else { // new OVER
over = true;
mouseOverFn(evt);
}
}
function mouseOut (evt) {
if (!over) return; // already OUT, ignore.
debounceTimers.push(window.setTimeout(function () {
over = false;
mouseOutFn(evt);
}, debounceMs));
}
function removeEventListeners () {
element.removeEventListener('mouseover', mouseOver);
element.removeEventListener('mouseout', mouseOut);
}
element.addEventListener('mouseover', mouseOver);
element.addEventListener('mouseout', mouseOut);
return removeEventListeners;
}
var someEl = document.querySelector('.container'),
textarea = document.querySelector('textarea'),
mouseOver = function (evt) { report('mouseOVER', evt); },
mouseOut = function (evt) { report('mouseOUT', evt); },
removeEventListeners = mouseOverOutDebounce(someEl, 200, mouseOver, mouseOut);
function report(msg, data) {
console.log(msg, data);
textarea.value = textarea.value + msg + '\n';
}

<div><span>shanghai</span><span>male</span></div>
For div like above,when mouse on,it should become cursor:pointer,and when clicked,fire a
javascript function,how to do that job?
EDIT: and how to change the background color of div when mouse is on?
EDIT AGAIN:how to make the first span's width=120px?Seems not working in firefox
Give it an ID like "something", then:
var something = document.getElementById('something');
something.style.cursor = 'pointer';
something.onclick = function() {
// do something...
};
Changing the background color (as per your updated question):
something.onmouseover = function() {
this.style.backgroundColor = 'red';
};
something.onmouseout = function() {
this.style.backgroundColor = '';
};
<div style="cursor: pointer;" onclick="theFunction()">
is the simplest thing that works.
Of course in the final solution you should separate the markup from styling (css) and behavior (javascript) - read on it on a list apart for good practices on not just solving this particular problem but in markup design in general.
The simplest of them all:
<div onclick="location.href='where.you.want.to.go'" style="cursor:pointer"></div>
I suggest to use jQuery:
$('#mydiv')
.css('cursor', 'pointer')
.click(
function(){
alert('Click event is fired');
}
)
.hover(
function(){
$(this).css('background', '#ff00ff');
},
function(){
$(this).css('background', '');
}
);
I suggest to use a CSS class called clickbox and activate it with jQuery:
$(".clickbox").click(function(){
window.location=$(this).find("a").attr("href");
return false;
});
Now the only thing you have to do is mark your div as clickable and provide a link:
<div id="logo" class="clickbox"></div>
Plus a CSS style to change the mouse cursor:
.clickbox {
cursor: pointer;
}
Easy, isn't it?
add the onclick attribute
<div onclick="myFunction( event );"><span>shanghai</span><span>male</span></div>
To get the cursor to change use css's cursor rule.
div[onclick] {
cursor: pointer;
}
The selector uses an attribute selector which does not work in some versions of IE. If you want to support those versions, add a class to your div.
As you updated your question, here's an obtrustive example:
window.onload = function()
{
var div = document.getElementById("mydiv");
div.style.cursor = 'pointer';
div.onmouseover = function()
{
div.style.background = "#ff00ff";
};
}
<div style="cursor: pointer;" onclick="theFunction()" onmouseover="this.style.background='red'" onmouseout="this.style.background=''" ><span>shanghai</span><span>male</span></div>
This will change the background color as well
If this div is a function I suggest use cursor:pointer in your style like style="cursor:pointer" and can use onclick function.
like this
<div onclick="myfunction()" style="cursor:pointer"></div>
but I suggest you use a JS framework like jquery or extjs
