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.
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.
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?
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.
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
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.
Can Javascript be used to detect a certain url and then "not" write some html according to that url and also detect something on the page and "then" display some html?.
Example: I'm working on a volusion site that uses asp. There's basically only one page that's changed dynamically. I would like to display some html when and only if the cart has any items in it. But also not to show up on the check-out pages.
The page dynamically displays "Your cart has 1 item in it..." when the visitors puts something in their cart.
So could javascript detect when this is displayed then write some html and then also detect if the url is showing the cart and then not show the html?
I am trying to make a function run if the mouse is moved over the document but when using the object onmousemove it seems to run the code even if the mouse is still over then document, how can I make it so if the mouse is over the document but isn't moving then don't run the code but once the mouse moves run the code? This is the code I made to handle the mouse move collections.
[Code]..
But with this code it runs even when the user doesn't move their mouse and the notification box pops up every second as the code seems to think a still mouse is a moving mouse.
I was thinking about having a run once system but that would mean if the mouse moves it runs once and then if the mouse moves again the code will not run as it has already ran before.
I have one some "li", i want use jquery.attr() add "onmousemove=(some each)" to li, like <li id="s" onmousemove="some(i)"></li>,this "i" is each.but it is do not work. how can i do it?
I was making a website, all looked great, untill I started IE7. there, it really looked like crap.Now I'd like to just make another css file for IE6 and/or IE7 but not for IE 8, because it does look wel at that browser.
Is there a way to detect which textarea the cursor is positioned in? I would not want to attach 'onkeypress' to all textareas to detect which one I am presently in ... or is this the only option?
how I might use JavaScript to detect the overflow of text in a DIV. Currently, I have the CSS set to Code:
overflow:auto
However, having scroll bars are pretty tacky. Instead, I'd like to be able to detect the overflow, which would then add a small <a href> link that says "More."
I was wondering how I could detect if a user has ad-block or ad-sweep or any other ad blocking ad-ons for that matter. I want to be able to detect this because if they do have ad-block I want to display an image in the place where the blocked ads are. That way theres not all this empty space
i was developing a blog and I came across may site have recaptures to prevent spams.but my opinion is using recaptures will avoid the number of users put comments in the site as an example you can consider myself that doesn't like that feature.problem is how to detect the spams ? Is there any mechanism to detect, if so I want to set it to my site.
Is there any way I can detect if there is a scroll bar on the right of my web page.
I use a javascript drop down menu and position it precisely with certain pixel count. It's a photo gallery.
However, if the picture has an extra size, the menu looks ugly with a scroll bar on the right. I've tried every method found on Google search but it's not working.
Pardon a silly question, but what's the best way to determine if a variable is an array in JavaScript? I need to treat it differently depending of if it's a string or an array.
if (navigator.appName == "Microsoft Internet Explorer"){ if (version.substring(0,1) <= 4){ if (version.substring(22,23) <= 4){ document.write("This Browser is IE4 or lower!"); } else{ document.write("This Browser is IE5 or higher!"); } } } else{ document.write("This Browser isn't IE!"); }
document.write("<br>This Browser is " +version); </script>
The version string usually return's something like this:
4.0 (compatible; MSIE 5.0; Windows 98; DigExt)
Can anyone see any problem with using this method?
