<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.
I getting an error on the page: Object expected please see code.
function SentTO(){ var toTxtBox = document.getElementById("btnTo"); var NameList; var ListBox = document.getElementById('<%=lstNDisplay.ClientID%>'); alert("stop here"); // code works to this point if(ListBox != null){
Form that code I would expect the class of 'testclass' to be applied to the button after the link is clicked, but It doesn't seem to work. This is a somewhat contrived example. In my real application I have a form with several collapsable/expandable sections. If the fields in those form sections have values when the page loads, the section needs to be expanded, and the expand/collapse button needs to have a class of 'expaned' applied to it, if not it needs to be hidden. I can check the form fields and show the div if needed without any problem, but I can't seem to figure out how to work out the selector so I can add the class to the 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
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.
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).
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.
The very simple code (below) works fine in Safari (and Chrome, Firefox etc.), but it doesn't work in Mobile Safari. Why?(You can find a working example at: http:[url]....)
Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head>[code]......
I'm working on some code and am running into brick walls. I'm trying to write out Javascript with Javascript and I've read the clj Meta FAQ and didn't see the answer, read many similar posts (with no luck though), and searched through the IRT.ORG Faqs (www.irt.org/script/script.htm).
The Javascript is designed to open an popup window and then inside that window call another script which will resize that window. There may be another way around this but the reason I tried this approach initially was that I wanted to call the onload handler in the popup window to resize the image only after the image had completely loaded. I've had some code in the primary Javascript file (showimage.js) before that works if the image has been cached but on the first load, it doesn't resize properly which tells me it is probably because it is trying to resize the window based on the image size but it isn't completely known at that point. So I removed that code and tried placing the resizing code in the second Javascript file (resizewindow.js). BTW I've tried other code to open a popup image and automatically size it ie Q1443 at irt.org but that doesn't do exactly what we need.
Even if there is another way to do this with one file, I still want to figure out why this isn't working in case I run into it in the future.
I thought what I would need to do to use document.writeln to write Javascript would be to escape any special characters and to break apart the script tag ie
document.writeln('</SCRIPT>');
would become
document.writeln('</SCR' + 'IPT>');
I have a HTML page and 2 Javascript files. All files are in the same directory and have permissions set correctly.
Here are the 3 files (keep in mind wordwrap has jacked up the formatting):
index.html ---------- <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Test</title> <SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1" SRC="showimage.js"> </SCRIPT> </head>
<body> Click the house<BR> <A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG SRC="house1thumb.jpg"></A> </body> </html>
showimage.js ------------ function newWindow1(pic,sitename) {
resizewindow.js --------------- function resizewindow() { // Do resizing here. // Right now this isn't being executed alert("resizing window"); }
Can anyone provide some pointers as to why this javascript is failing? I'm using IE6 on Win2k and when I click on the image to open the popup window, it does open the window but it is white with no content and the system immediately goes from about 4% CPU usage to 100% and consistently stays there until I kill that window with the task manager.
Attached is a simple HTML file that adds and delete rows. In the add row function I set an attribute "onClick" this triggers the testMessage() function. When I try this in Firefox it works just fine however on IE it just refuses to work.
What is interseting is the ROW that already exists has a similar 'onClick' event which works when the page is loaded, but subsequent "row" additions to the table to not work in IE. Code:
