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).
The code works as expected in Chrome, but not in IE and FF. In IE the error is "Object doesn't support this action" and in FF "setting a property that has only a getter". In Chrome there is no error in the console. There are three javascript <script>...</script>s that exist to display a <td> row in a table with a particular graphic depending on the screen width. The odd thing is that in both IE and FF (and of course Chrome), the first two scripts display perfectly well. Why does the third <script> produce an error? It has exactly the same form as the two before it.
I can only guess it has something to do with where it occurs :confused: Googling the FF error, it has something to do with trying to set a read-only property, but then why do the first two <scripts> work? They are no different (at least I can't see a difference.)
Trying to add a new property to a non-jQuery object from inside each loop doesn't appear to work: var arguments=new Object(); arguments['ticket']=ticket; arguments['email']=email; arguments['module']=module; arguments['epoch']=new Date().getTime();
var total=0; $('select.category').each(function(){ var name=$(this).attr('id'); var option=$(this).find('option:selected').val(); total+=parseInt(option); arguments[name]=option; });
The 'total' variable works as expected. The the 'arguments' variable doesn't. Almost like a variable scope issue or something. If I put some extra debug code to print out all the property/value pairs, outside each loop I only see original four, and inside each loop only the new one just set and none of the original four.?
I am currently encountering a problem with setting "display" property from "none" to "block":
Browsers will refresh itself when the display property is changed; this causes the element to display then suddenly disappear after the page reload. Do you guys have an idea what I can do to avoid it?
I tried using jquery's show command, css command with setting display to block, and pure javascript method like document.getElementById("theId").style.display="block".
I have a script that slideshows 5 images. Below the images is a numbered list; 1-5. I'd like to set the style of the number buttons based on the image being displayed as the images scroll from one to the next. Code:
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 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?
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.
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
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.
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.
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.
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?
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.
I'm trying to create a control which when the mouse button gets pressed on one div an absolute positioned div pops up in place of the cursor. From there the cursor should interact with the dialog before the mouse button is released. In other words one element will catch onmousedown, display the popup, and the popup element will catch onmouseup. This works fine in IE as the popup automatically accepts following events, but my problem is in Firefox.
In Firefox everything behind the popup still receive events even though they can't be seen (hidden by the popup). I have to release the mouse button and then click on the popup again before it accepts the onmouseup event.
I also used a different cursor on the popup to see if Firefox recognized it was there at all. Still the cursor doesn't change until I release themouse button and move the cursor across the popup element.
I've tried focus/blur, timeout delays, hiding the first element (the one which receives onmousedown) but nothing works.
The only thing that works is hiding the entire body and then using setTimeout to show the entire body again 1ms later. Obviously though that is very ugly.
When a user pushes their mouse down on a DOM element I want to allow them to move it, so I would like to setup an on mouse move function. The code i have is:
I want to add a global event handler for mousedown that will register whenever the user clicks anywhere on the page but I'm having trouble.This is what I'm trying to do:
var body = document.getElementsByTagName("body"); alert(body); body.addEventListener(mouseDown, myHandler);[code]....
But the event handler is never called. I can't even seem to get access to the body. Is the body tag the wrong place to be assigning the mousedown handler? I'm trying to make this code work correctly in both IE and firefox.
