Onmousedown And Onmouseup While Dragging
Jul 23, 2005
I am trying to let the user drag a rectangle over an image, which will
then let the user zoom in on the dragged area. However, I am doing
something wrong in implementing the onmousedown and onmouseup events.
Everything is very simple so far. I just defined an onMouseDown event to
record the event's x and y locations as the starting point, and an
onMouseUp event to record the x and y of the end point, and this function
gives me the results of both in an alert box.
The problem is, that the OnMouseUp event does not get fired if I move the
mouse while holding the left button down. This only works if I click down
and then up at the same point, which is not what I want.
What could be wrong? Why does the browser not recognize the mouse up when
the mouse is moved while holding the left button down? How do I fix this?

my script looks something like this:
<body onmouseup="b.innerHTML='2';">
<button id="b" onmousedown="this.innerHTML='1';"/>
now the problem is that if the user presses the button, and while he have not released the button, he Alt-Tab to another window and release the mouseclick at the other window. And when he returned to my webpage, the mouseup event never occured and is "lost"!how do we stop this from happening?

I'm trying to experiment with some javascript to do some custom
dragdrop handling. I wish to use the onMouseDown event to trigger the
start of my drag, and onMouseup for a potentential drop. I hope to
turn on the onmouseup only in onmousedown. And eventually go one step
further and incorporate onmousemove for a true drag workflow.
I'm running into a problem however, where after mousedown, mouseup will
not fire when I release the mouse button. It will however fire if I
click again. So the event isn't being tracked until I release the
mouse the first time apparently. Which ruins my dragDrop of course.
Below is the code. You can see a move() method that would incorporate
onmousemove, but for the most basic test I'm just using beginDrag and
endDrag.
Any ideas why onmouseup won't fire until I release the button, then
click again?

Here is a simple version of the relevant line of my code:

There is no response for onmouse down, but onmouseup generates the appropriate alert. why onmousedown doesn't work?

Code:
I have a display pic which is supossed to change when a user presses one on the numbers (bottom right hand corner) but it doesn't change all the time. Sometimes you have to double click, sometimes hold the button down.
Also when you click and the image doesn't appear you can right click where the image should appear and select 'show picture' then it appears.

If I perform a mousedown within a document, move the mouse outside the
browser window, and then release the mouse button, the document.onmouseup
event does not fire. Is there any way to detect a mouseup event outside the
document?
Also, how can I get the relative coordinates of the cursor while it is
outside the browser?

This is a really basic question: what does blur mean, or what does it do when used in links as described below? I've tested it on Firefox 3.6 and Opera 11 and it behaves as I hope except for one thing. During testing if I use both keyboard and mouse to navigate within the same session, the browser history for the 'other' method is wiped out; it won't go backwards beyond the most recently used method. Is this not a surprise when you know what blur really means? I want the following (assuming Javascript is enabled):
a) Keyboard users to see a focus outline on navigation links.
b) Keyboard users to see the outline still there if they use the browser Back button, and continue tabbing from that link onwards.
c) Mouse users to NOT see an outline if they use the browser Back button.

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
<g id="0" style="display:inline;fill-rule:evenodd">
<desc>0</desc>
<image id="image_url0" xlink:href="draw_svg.svg" width="1000" height="1000" onmousedown="doZoom(evt, 1);" onmousemove="doZoom(evt, 1);" onmouseup="doZoom(evt, 1);" />
</g>
2) 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 wrote a script that uses onmousedown and onmouseup in javascript that
works great in ie and firefox on windows2000. It looks as if the
pocketpc 2003 ie browser dosn't support onmousedown or onmouseup and
only such as onclick.
I need to be able to submit a form when the mouse is held down on a
button and submit a different form when the mouse is lifted up from the
button. could anyone tell me of anything I could substitute onmousedown
and onmouseup with, i know onclick could substitute for on mouse up but
i'd prefer not to but i still need somthing for on mouse down.

<a href="#" onmousedown="callMyFunction()">Press the mouse button</a>
What I expect is when I or an user move mouse pointer over that link,
and press the mouse button. Then will "callMyFunction()" over and
over again until I release the mouse button (mouseup).
But what I found out the onmousedown is just acts the same as onclick.
It only "callMyFunction" once. If I want to call again, I need to
keep repeat mousedown, mouseup like clicking. That is not cool at all!
So The implementation for onmousedown in JavaScript is different from
mousePressed event in MouseListener interface in Java.

Is there a way to access the value assigned to onmousedown for an
object? I've been searching online but can only seem to find how it is
assigned via html. What I need to do is access the value (the script
string) in javascript.
For example, I'd like to try to do something like this:
function virtualClick(objectName) {
eval(document.getElementById(objectName).onmousedo wn);
}
I am of course not explaining the full problem in detail, but would
appreciate any input on how to access the onmousedown value (or to know
if it even exists as a property).

I'm trying to make it so when I click a image it prints out the image
again and a load of other stuff. So far i've got this far.
<html>
<head>
<script language="JavaScript" type="">
document.onmousedown = onmousedown;
function onmousedown(e)
{
document.writeln("hello");
}
</script>
</head>
<body bgcolor="FFFFFF">
<img border="1" src="iecadaptor.jpg">
</body>
</html>
but in Mozilla it prints out hello then hangs looking like it's doing
something then I have to press back. In Explorer it works doesn't hang.
Any ideas anyone why it's hanging in mozilla(linux)?
Also if I change the document.writeln("hello"); to
document.writeln("<img border="1" src="iecadaptor.jpg">");
it doesn't print out an image just hangs in mozilla. Any ideas?
Ideally I would like it so document.writeln doesn't have to reload to a
new page and just uses a layer using <div stuff but that's next.

I have 9 boxes which I can drag around an invisible grid however when the onMouseDown function is called for the first time on each of the boxes, they behave erratically, then once all boxes have been clicked once, the entire script works as it should. I've tried using default values when declaring the variables however it doesn't seem to do anything.

onMouseDown works fine for me in IE but not in Firefox. All I need to do is to trigger confirm() when a button is clicked. However, as soon as I click the button, the confirm window pops up ok but the form gets reloaded at the same time.
<form name="test">
<input type="textarea" value="test">
<input type="submit" value="true" onmousedown="confirm('ok?')">
</form>
If I modify the value in the textarea and hits submit, I'll see the confirm window but the form gets reset and value of the textarea is back to its initial value of 'test'.

I am looking to have a javascript that can be included a page that can highlight or set a border for a the div, p, span, or img DOM element when clicked on. Now this element may or not have a element name or id. And also, the code on the individual objects do not have a onmousedown behavior.Lets say for example there is this code.
<div class="HeaderLogo">
<div class="logo">Copyright © <?php echo date('Y'); ?> My Website All Rights Reserved.<br />
<img src="../images/template_2/website-logo.png" alt="MY Website - CMS" width="413" height="51" />[code]....
And in the browser, I wanted mousedown on a section of a page and highlight the parent object. Suppose I moused-down on 'My First Sentence Text', its parent would be that p tag. Is there a way I could reference that p tag so that I could highlight it with a border. Granted, this would be a no brainer if that p tag already have an id and name, but in this it does not.

I'm trying to drag a bunch of images in a Google maps-esque style. The
javascript is pretty simple, but whenever I go and drag over a large
image the image toolbar comes up in IE and the image looses focus. How
do I get around this? Is there a way to disable that toolbar?

I have an SVG file and draggable div on one page. When I move div over
this SVG file, it looks like div loses control and detaches from the
mouse. If I do it slowly, div seems to barely follow the mouse which is
being over SVG.
I tried assigning zIndex to SVG file to be the same as other elements
on the page, but that did not help. Would anyone know why this happens?

I am currently using multiple include files with my website and my issue is specifically with my navigation include. All I'm using is a simple unordered list with images for list items. Ofcourse each list item/link takes you to a another page. I have up, over, and down images for each menu list item. What I need to figure out is how to keep the associated menu item's down image active when taken to the associated page.I'm assuming it might entail some Javascript within the navigation include or per list item that tells the browser to keep the down image active when landing on a certain URL. I don't know what that code is.

In a nutshell: I have an html code that looks like this:
<span class="someClass">
Beginning of a text
<label>[code]....
What I wanted to do is to transform it into this: Beginning of the text option 1 end of the text.where option 1 would, onclick, change into option 2 (checking the appropriate radio button at the same time)
The result of clicking option 1 would then be:Beginning of the text option 2 end of the text and you would know that the radio button for option 2 is checked.
This way, by clicking on option 1 or option 2, you get to see the change in the "sentence".b.t.w the reason I wanted to have radio buttons in the first place was, firstly,to pass the chosen information in the form, but also to avoid loosing functionnality when javascript is disabled.The reason why I chose to wrap the labels around the radio buttons is so that clicking the text would check the appropriate radio button..( I could use the for attribute, but thought it would be easier this way as far as scripting goes)here is what I did (in english, and in javascript[code].....
All of this works wonderfully, except in opera. I think it is because opera does what I say, but then proceeds to checking the radio button associated to the clicked label (as a label should do). In other words, the script is useless since opera does the label effect after my script has taken place, cancelling my script's effect.The reason I think this, is because I tried putting an alert where the red comment is and that solved the problem. I'm guessing that the alert prevented me from completing my click action (because the alert box has and keeps the focus), thus preventing the natural label activity.

I have created a drag script and am having a problem with the cursor.When I hover over the div, the cursor becomes "move" as I want it to be.But if I click, then drag it changes to the I-beam cursor.I am wondering what I can do to get it to stay "move" or whatever I'd like it to be.I know things like onselectstart, etc, but that doesn't seem to do anything.
