Erratic Behaviour OnMouseDown?

Sep 6, 2010

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.

Working But Erratic And Messy?

Feb 4, 2011

I have sort of got it working....... The javascript seems to be very erratic though. Sometimes it just won't bother executing it's commands!! For example, I've asked it to reload the page after it has completed it's job. And also to output the result so I can see what's happening. Sometimes, even though it does the database part, it doesn't bother to let me know or to reload the page!Also, sometimes, it will let me know it's done it's job, and then it will reload the page, but then I will find it hasn't actually done anything in the database! I can't understand why a script can appear to have a mind of its own!!

The other thing I'm bothered about is the messy look of my script. Because I have 3 forms, one to add a category, one to remove a category, and one to rename a category, I have had to duplicate the javascript function 3 times, giving each one a unique name to be called by the relevant form.Here's the full script.

<script type="text/javascript">
function remove_category()

JQuery :: Menu SlideUp Is Very Erratic?

May 11, 2009

I've inherited some unfinished code for a menu system (previous developer left the company before he could finish it). The menu worked fine until the client wanted some nested lists, which is when the height was being set incorrectly. I had a fiddle and I can get the height to report correctly, but it's extremely erratic as to when it will actually drop down. I've stripped the code out into a file on its own, complete with a lovely colour scheme. the code I added can be streamlined somehow. I'm only just getting to grips with JavaScript & jQuery. Test version:[URL]..

Removes Default Drag Behaviour On Image In Netscape

Jul 23, 2005

I am trying to implement a rubber band/image selection script. For
that I need to remove the default drag behaviour on an image. I am
able to do this in IE but not Netscape. Does any one have a solution?

Pls look below for IE code:

var moz = ((document.all)? false : true);
var ie = ((document.all)? true : false);
var ElementUtil = new Object();
ElementUtil.addEventListener = function(o, type, handler) {
if(ie) {
o.attachEvent("on" + type, handler);
else if(moz) {
o.addEventListener(type, handler, false);

// Removes default drag behaviour on image in ie
ElementUtil.addEventListener(img, "drag", function() {return false;});

JQuery :: Add Show And Hide Behaviour To Multiple Classes

Nov 9, 2010

adding my show and hide behavior across various classes, so the message shown will be unique to the class.

My J-Query looks like this;

<script type="text/javascript">
$(document).ready(function() {
$('#One').hide(); /


I have include a demo that should make it clearer, as to what I want to achieve. Ideally, each box will show a unique overlayed message as the user's mouse enters the box and hide once the mouse leaves.

JQuery :: Cycle Plugin - Frame Number / IE Behaviour?

May 19, 2009

As implied by the subject, my question concerns jquery.cycle plugin and I have 2 questions. I tried to find answers searching the web, but didn't find any. I'm currently using cycle to built a photography website and enjoy it a lot so far. However, I'd like to display/update the image number at the same time as the legend (taken in the "alt" of the images). i.e, I'd like to be able to write something like "current frame number / total number of frames" in a div, somewhere.
It looks like somebody heavily edited the cycle plugin for the[URL].. to do what I want, but it's not really made in the most elegant way (the cycle plugin is modified, the div name is hard written in the code...). If I find no workaround, I might do it the same way, but I'd prefer avoiding modifying the plugin, if that's possible. So here's my first question : Does anybody know how to display the frame number (and total number of frames) using the standard plugin, only putting some code in the after: function callback ? Second question : with IE7, if all images are already in cache, they all display on the page before the cycle starts and hide them. (one of the page is here : [URL]...

Onmousemove And Onmousedown

Jul 26, 2005

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">
<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);" />

2) JavaScript function:

function doZoom(evt, current) {
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.

Strange Behaviour In Internet Explorer With Document.links[i].href

Jul 20, 2005

I have to change dynamically all hyperlinks, when the html-page is
loaded at the client. This works fine, except in the following scenario:

When the innerText of an anchor contains an '@', the InternetExplorer
changes the innerText-Property to the HREF-Property. I have checked this
with MoZilla/FireBird and Opera and there is no problem!

To explain, what i mean, see following example:
function atTest(){
for(var i=0; i < document.links.length; ++i)
document.links[i].href = document.links[i].href;


Now you need some anchor tags - notice the '@' as inner Text:

<a href="">Text before @ and after</a><br>
<a href="">Text before @</a><br>
<a href="">@ before text</a><br>
<a href="">Text before at and after</a>

If you load the page, InternetExplorer will display the HREF-Property
instead of "Text before @ and after" - all other elements are shown
correctly! It doesn't bother other browsers: Opera/MoZilla shows _even_
the first element with innerText.

My system: Windows XP SP1, InternetExplorer SP1, Firebird0.7, Opera 7.23

Has anybody out there an idea, why IE behaves like this? And how I can
work around this?

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?

Onmousedown Pocketpc 2003

Jul 23, 2005

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.

Onmousedown Is Not What I Expect In JavaScript

Jul 26, 2006

<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.

Setting Onmousedown As A Property Value

Sep 12, 2006

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).

Onmousedown Hangs In Mozilla

Jul 20, 2005

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.

<script language="JavaScript" type="">
document.onmousedown = onmousedown;
function onmousedown(e)
<body bgcolor="FFFFFF">

<img border="1" src="iecadaptor.jpg">


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.

Problem With OnMouseDown In Firefox

Nov 28, 2007

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?')">

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'.

Onmousedown Highlight DOM Element?

Jul 30, 2010

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.
