OnmouseMove Not Work With SetTimeOut And Alerts In Chome?
Apr 7, 2010
What's wrong with this code? It works in IE and FireFox, but Chrome does not work. The idea is that the function fnTimeOut will be triggered in 5 seconds after onmousemove (fnTimeOut was attach in onmousemove in document). It�s ok. But when, in Chrome, I click on the button "ok" to function fnAlert is triggered instantly. It should be shot just 5 seconds after I move the mouse
I'm writing a JavaScript Equation Editor / Whiteboard App, and i seem to be having a problem with one line of JavaScipt Code.... The Equation Editor is hosted live here:[URL] I have used the DOM Inspector (i'm using firefox) to look at the onMouseDown= event code, and it should work.... However, when i try to drag a Math Element Image to a different location (after it has been added to the page by clicking on the Math Element Keyboard), it does nothing. I looked on the Error Console, and there is nothing there.
I looked at the Node value in the DOM inspector, and it is as it should be. I have also tried changing and removing some double quotes and single quotes, as that has worked in the past on similar code snippets.
I had a bunch of javascript, pretty simple stuff, working perfectly for many months. I haven't changed any of the code for just as long, and suddenly a bunch of stuff isn't working. Here's an example.Suppose I have a form
Basically, my problem is exactly as described in the subject. The problem is somewhat intermittent and unpredictable, but the majority of the time if I just have a statement such as
window.onload=location.hash('somewhere');
the URL is indeed appended, i.e. www.example.com/index.php#somewhere, but window itself doesn't actually move to the bookmark. However, if I do something like
it works fine. On very large pages, the timeout actually has to be a second or two. Any idea why this is happening? I don't know much about JS, but my thought is that it's trying to move to that bookmark before it has actually been loaded in the page; the timeout forces it to wait for the rest of the page to load before going to the bookmark.
I put an onMouseOver and an onMouseOut event on a div. The onMouseOver works well but the onMouseOut looks worked like an onMouseMove; the event is triggered when a move the mouse over the div.
is it normal? What should I do to avoid this problem?
I am new to JavaScript and kind of confused as to why my onmousedown together with onmousemove condition is not being implemented. Here is what I have: 1) SVG code calling JavaScript function
function doZoom(evt, current) { //THIS SHOULD WORK if (evt.type == "mousedown" && evt.type == "mousemove" ) { var SVGDoc = evt.getTarget().getOwnerDocument(); var SVGChild = SVGDoc.getElementById("maps"); var svgobj = SVGChild.getElementById("0"); svgobj.getStyle().setProperty('display', 'none'); } }
But the code works only if I say: 'if (evt.type == "mousedown") without "mousemove" . Please note, that I am calling my function onmousemove event also so it should register. I will very much appreciate if somebody could tell me why 'mousemove' AND 'mousedown' both don't work in my 'If' statement.
I am currently trying to write some javascript that detects mouse movement in some way or another. This is for a website vistitor tracking script i am writing. The purpose would be to detect if the vistor is human or robot. Right now myfunction() grabs the info and inserts it into our database if any mouse movement is detected. But the script executes every time the mouse moves on the same page. So we are getting multiple log entries when we only want one.
So my question is this: Is there a way to once javascript has detected mousemovemnt once, to not detect it again? here is my code document.onmousemove = function() { myfunction();} I am not all too familliar with javascript and will probably need written out examples to grasp this.
My functions for mouse_move / up / down all control the movement of a box. So you can click a box and move it anyway. It then snaps to an invisible grid. However there are multiple boxes on the screen so if you move it to a spot where another box already resides, then that box needs to swap places.This is what the mouse_over function tries to do. When I click the first box it stores the position of that box that was clicked. If I release the mouse button whilst hoovering over another box I want the other box to take the stored positions of the first box.However what I think is happening is the mouseover function is applying the new position to the box I'm moving, as I guess this is the first layer the mouse is over.Is there anyway I can reference the layer underneath using onmouseover.
Basically, the phenomenon I'm seeing is a change in how often the onmousemove is triggered. My site has 1 up to n (n can really be any number) of moveable, resizable divs, each with dynamic content, but I noticed that on various browsers, the moving/resizing displays phenomenal performance differs. On Firefox -- it's as real time as it should get and I'm happy with it, but in IE, Safari, and Opera (I have not tested this under Linux or MacOS) things are much slower.
Anyway, after hours and hours of optimization, it occurred to me to begin capturing the mouse coordinates in realtime in the content of one of the windows. In other words, whenever I move the mouse anywhere on the page, it's coordinates are returned by window.event.clientX/Y or event.pageX/Y appear in one of the 1 to n windows.
To my surprise, the rate at which those numbers changed only stayed constant under Mozilla. But on each of the other browsers (Safari by far the worst) depending somewhat on how many boxes were displayed on the screen and where on the screen I moved the mouse, the coordinates that displayed in the box updated only with every 10 -- even 100 pixel movement causing seriously choppy movement.
I'm sure without demonstration this is not coming across clearly, but if anyone has any insight into how the onmousemove timing works, I'd appreciate it.
My site is similar to Meebo -- and if you'll notice, dragging their objects stays relatively smooth across all browsers, and I simply can't get the onmousemove timing to not be choppy -- I've put it in <body> as well as in a <div w:100% h:100% that covers the entire background>.
I do have a fair amount of transparency which could of course cause some CPU intensity, but I don't see how Firefox would be that much more optimized (the performance difference is phenomenal). My system is a dual 2.8 Ghz Xeon with 1GB ram -- neither is being maxed out.
My theory is that somehow there is a "setInterval" equivalent built into the event object that is variable but only controllable by the browsers.
In IE6, putting the mouse on each of the two items highlights the word in a blue (different image) and shows a tool tip. In Firefox(1.5.0.6), nothing shows when mouse goes over it. Please view the source of that simple page (with some JavaScript) to see if you know how I can get this to look in Firefox like it does in IE?
can someone explain how i can use an ondblclick event to cancel an onmousemove event? would I use cancelBubble for this? i have a statement in my header document.onmousemove = updateMouseCoordinates; that moves a sentence of text around the screen. when i try to call a function using ondblclick event in the <p> tag, it fails to call function. without statement above, the function is called.... my purpose is to just cancel the onmousemove in event user performs a double click.
Is it possible to disable/suppress alert popups in javascript? I need to write a function that will loop through a form's inputs and "manually" fire their onchange events (if found). Some of those functions could popup alert boxes which I'd like to be able to temporarily suppress.
for debugging, i create some alerts that can be sizeable. see attached for a sample of 1 that got truncated about 50% of total. is there someway to increase the size of the number of characters allowed in the alerts?
[URL]. It works awesome in all browsers but IE 7 & 8. The custom "alert" is actually a dialog box, with a background fader underneath it, kind of like lightbox. Why IE doesn't play nice?
i am in the middle of creating a members area system which has went well up to now. I need to create a button that will turn alerts on and off for example when the user clicks the button it will show turn on and vice versa however each time they select the button i want it to update the database with its current state so the admin knows who is currently accepting alerts.
Preloading images has got to be JS 101. However, it does not seem to be working. Here is the function that I am using. I added the alerts to make sure it is working and all the right alerts show up, yet when I do my mouseover, it still takes about a second (only the first time) to load the image (thumbnail).
loadims(max, letter) {//loads information images if (document.images) { max++; alert(max); for(i=1; i < max; i++) { rslt = new Image(); imgn = 'm/' + letter + i + '.jpg' rslt.src = imgn alert(imgn); } loaded = true; }}
I have a Java-based web application whose interface can be in multiple languages. My requirement is that the javascript alerts that I display should be displayed in the language in which the interface has been generated. The interface language is dynamically loaded and the text is displayed using Java's <fmttags.
How can I make the Javascript alerts, etc. also change their display language dynamically? Is it possible in Javascript or do I have to use another technology to do the same?
I'm trying to develop a to-do-notification thing where I can select a specific time to be notified in real-time without any need to reload the page...
My goal is to be notified 1 day ahead the expiration date that I have set. And if the due-date is on a monday, I need to be notified on the friday and not sunday...
I was wondering if this could easy be done with jQuery? I have set up a MySQL table with all of my to-do's. 1 row for each to-do with a date-column.
Code: <script type='text/javascript'> var value; initEditor('tbMsg', true);[code]....
It works and alerts 1, but that's only if 'ifm' is set. If I were to take the above code and backspace out the i in ifm so it was fm, when I refresh my browser neither 1 or 2 gets alerted. Is this javascript's default behaviour, if so how can make it alert 2?
Code: <iframe src="http://www.cult.co.uk/men/shop/hoods-and-sweats/details/25705/75-wings-foil-hood" width="500" height="500" id="iframeTest"/> the page from cult.co.uk has javascript alert() messages embedded in the code, which are triggered when the page loads via the iframe.is there a way of suppressing the alert() messages?I know i can suppress alerts on my local site by adding the following function:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>Untitled Document</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta http-equiv="Content-Style-Type" content="text/css"> [Code]....
alerts the innerHTML content in all the browsers. Except in Firefox 3.6.8, which alerts a blank value. What the f?:confused: I know that innerHTML is not a standard DOM method, but it used to be a crossbrowser one since FF 1.5, right? Edit: It does not work even in case of firstChild.nodeValue or firstChild.data. FF 3.6.8 says that the DIV element has no first child, which is amazing.
I am trying to validate a web form. Someone else wrote the Html code and implemented it with an iframe using asp and php. I didn't want to mess too much with the code so I decided to use javascript to make the form validate, before it was sending email alerts with every field blank. For the most part the validation works but it skips the email field for some reasons and is really bugging me to death. this is the code:
