Function & Properties
Jul 3, 2007I would like to know the difference in Javascript between those two lines of code:
JavaScript Code:
oneobject.oneproperty = onefunction;
and
JavaScript Code:
oneobject.oneproperty = onefunction();

how to add extra properties to html elements as I was storing data in html attributes. After looking at some others code including Raphael and this addEvent code. [URL] They seem to treat objects just like an array. obj[property] = value; This would have been extremely helpful to know previously as I have needed to be able to include variables in property names - but have resorted to making the whole thing a string and calling exec() on it.

I want to change background of a paragraph or list item on mouseover. The
following code works:
<p onMouseover="this.style.backgroundColor='yellow'"
onMouseout="this.style.backgroundColor='white'">ppppp</p>
Now I want to minimize the coding bij using a function. How do I do that?
Without getting into too much history on the why, I came into a situation where I needed to create a function to get various properties of !DOCTYPE so that other functions could adjust to work properly with certain DOCTYPEs (Strict, Transitional, etc.). I have tested the function in the following Windows browsers IE6+ FF3+ Chrome2+ and Safari3+ Opera9+. The only one that I can’t get working is Opera (testing with 9.64). I’m hoping that someone out that has a solution! Here is the code:
[Code]...
I don't know why but after the animate() function it's like all the properties get wiped.
PHP Code:
bubble.prototype.expand = function() {
var _this = this;
this.mLeft = parseInt($(this.div).css('margin-left').split('px')[0]);
this.mTop = parseInt($(this.div).css('margin-top').split('px')[0]);
this.iWidth = $(this.iconImg).width();//icons dimensions
this.iHeight = $(this.iconImg).height(); .....
I am currently working on a tween script that I am hoping to make so it allows the user to choose and object than the property it tweens, whether it be height or opacity.so currently my problem is getting the function to accept dynamic property selction.for example, the following.
Code:
function tween(object,property,to,time){
original = object+property;

I'm getting errors in Firefox everytime I try to run this frame resize code, but it works fine in IE. I can't seem to figure out what the problem is with it.
The error is: Error: theFrame has no properties
Line: 8
The line that the javascript console is showing an error for is in italics.
code from page:
<html>
<head>
<script type="text/javascript">
var defaultCols="100px,*";
var hiddenCols="0px,*";
function ShowHideMenu(){
theFrame = document.getElementById("framed");
if(theFrame.cols == defaultCols) theFrame.cols=hiddenCols;
else theFrame.cols=defaultCols;
}
</script>
<frameset cols="100px,*" name="framed">
<frame src="lframe.htm" name="frameMenu">
<frame src="mframe.htm" name="content">
</frameset>
</head>
<body>
</body></html>
Come someone let me know what I'm doing wrong here?
I am getting a Javascript error from Firefox 1.0.5 when I try to reference a
table within a window that has just been opened and written to. I get the
Javascript error "cartTable has no properties" where cartTable is the
variable I assigned the table reference to.
cartTable=winDVDCart.document.getElementById("cartTable")
Previous to this, I have just opened a new window, used the document.write
method to write some HTML into it, and then used the document.close method.
At that point I call a new function to add some extra things into the new
window and this is the first statement that gets run. It seems as if the
table isn't quite finished loading when I try to reference it and that is
causing problems. I am not getting any errors in IE6 and it is working just
fine. I figured that maybe I could implement a loop to just wait until the
table is fully loaded but that will just loop infinitely for some odd
reason.
while (!winDVDCart.document.getElementById("cartTable")) {}
This code just loops infinitely, but if I just put an alert within the {}
for the while loop, it shows the alert once, I click ok and everything works
great after that. Could anyone point me in the right direction on this?
When i assign some css properties should i allways use the postfix like
measurment units (so use: 150px instead of only 150).
AwebappI am working onmust use millimeters instead of pixels for the top, left, width, height and font-size style attributes. There happens something strange when setting these style attributes with mm values.
[Code]...
It would appear that it is not possible to retrieve CSS properties such as min-width if they have been set from a class. However, I don't want to have to style everything directly with the style attribute whenever I need these properties. Is there a reliable method of getting these properties as applied to element from a CSS class?

Since object names can't simply be a number ie(this.oProducts.Product.0), how can I access the object properties in the list above?
i want to set page properties within the page itself. i can easily open a new window, but i don't want to have to do that. width, height, toolbar, scroolbar, navigation, etc... it seems like i've done this before, but for some reason i'm drawing a blank. any suggestions out there?

"this.objParent.objRequest" is null or not an object
As the requestChange method is called as the onreadystatechange function, ive had to assign a variable referencing the parent Ajax object to the requestChange method, which is done in the Ajax construct method. This allows me to reference the Ajax Request Object from the requestChange function.... in firefox at least. Code:

View 1 Replies View RelatedI am trying to perform an elementary animation using javascript to manipulate the CSS properties of a <div> tag.
I use getElementById in my first function to draw a line inside a <div> box like this:
function line(x1){
var cd=+1;
var c = (x1);
var division = document.getElementById("line1");
[Code]....
I am drawing lines inside of a <div> (wrapper) using <div> id's by incrementing the height and width properties using javascript functions. I use setTimeout to gauge the speed and clearTimeout for when the current line is finished being drawn. Then we call the next function to draw the next line ... etc.... etc.
At first I was going to go the whole "createElement" route. Then I thought "Why not go ahead and define all the lines and id's in the body of the page and just set the initial heights/widths to "0" (hence they will not be seen until we start to increment).

I have a number of show/hide images on my site which allows the user to click on various thumbnails to open up the full image using layer based styles.
However, my Javascript seems to have developed an error saying that the object has no properties and then takes me to the following line of code:
obj.visibility='hidden';
This code was written for me so that i could use the script dynamically with PHP an alter the number of div layers it needed to generate.
The full(?) javascript for this function is:
function showImg(myShow)
{
var loopNum=99;
for (x=1; x<=(loopNum); x++) //1 based loop

View 4 Replies View RelatedI want to display information on a page in a static way. That is, not
as part of text elements. I can't find an appropriate struts tag to

This what I did find. The form bean will be named the same as the

So if I have a form bean with 2 string properties, such as str1 and

I know that I can read/write custom properties of an object by using
the following:
Setting:
document.all['Control'].customProp = "this";
Getting:
document.all['Control'].customProp;
Is there a way I can run code when this custom property is set. Or
perhaps there is a way to create a custom method?
Example:
<span id="MySpan"><input type="text"></span>
I'd the property:
document.all['MySpan'].enabled = true;
To automatically do this:
document.all['MySpan'].controls[0].disabled = !thevalue;
OR the method
document.all['MySpan'].enable();
To do this:
document.all['MySpan'].disabled = false;
I try to associate DOM nodes with other objects. Assigning custom
properties to DOM nodes works in Firefox and Safari. It also works with
HTML nodes in IE6. However, it appears not to work with XML nodes that
are part of trees returned by XMLHttpRequest. How can I work around this
limitation? For XML nodes, I need to be able to associate at most one
object with each node.
The syntax I am using is
node.customproperty = value

I am trying to learn JavaScript--(complete newbie--and don't know C or
C++). I've been reading "The Book of JavaScript" by Thau.
I don't see anything about table properties in the book. (I would like

table changes color (between two or three specified colors)). How do I
get at the background color property in a table cell?
