Setting Custom Properties

Jul 23, 2005

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;

Custom Properties On DOM Nodes

Jul 23, 2005

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

Custom Properties On Xmlhttp Object

Jan 2, 2008

Say x in a XML Http Request Object ... meaning it's either XMLHttpRequest (firefox) or ActiveXObject (IE)

This line of code works in firefox...
x.someProp = "someValue";
alert(x.someProp);

But in IE I get "Object doesn't support this property or method" I need to place a custom property on the object. Is there any way I can do that in IE?

I've already tried ActiveXObject.prototype.someProp = "";

Basic Setting Of CSS Properties/innerHTML

Jun 29, 2009

I'm trying to create a script which allows multiple different tables to be shown on mouseover of an area (in this case, a table cell). However, I want the tables to appear in a long list for those who have JS disabled. For obvious reasons I don't want two copies of the tables in my html, and obviously only want the mouseover section to appear for those with JS enabled.

The basic problems I have so far is that I can't get the div "plaintables" (which contains all the tables) to be hidden when JS is enabled, and when I mouseover (activating scim()), I get the message [object HTMLTableElement] rather than the actual table.

Pretty much just starting out with Javascript, so this is probably something really simple I have done wrong.

Just incase it matters, I don't have access to the contents of the <head> tag (This is for a site with an existing template) - it would be easier if everything could be done in the <body> section.

Accessing Element Properties After Setting InnerHTML?

Mar 21, 2010

I am dynamically building a part of my HTML page by setting the innerHTML of a DIV element. Immediately after I do that I try to retrieve the clientHeight and clientWidth of the DIV element in order to determine what height and width the element actually ended up being. But I always get 0 as both the height and width. The contents of the DIV, i.e. the HTML code that I inserted into it via the innerHTML, does indeed get displayed on the page. But I suspect that the browser doesn't actually update the page until AFTER my JavaScript code has completed and "returns control" to the browser.

Does that make sense? Is there any way I can force the browser to update the page BEFORE my code completes its processing, so that I can properly retrieve the width and height of the element I just inserted into the page?

Triggering The Execution Of Code With The Setting Of Object Properties

Sep 22, 2006

Subject line would seem to say it all:

How does one trigger the execution of a method within an object or any
other code/function with the setting of an object property?


More elaboration for those who want it:

Suppose we have anObjectType, with a property .description, whose value
can be a string, and the value of .description actually describes the
structure of anObjectType as a string. (The details are not important
about how the structure is described, but if you want something concrete,
think of 'anObjectType' as a DOM Node of type NODE_ELEMENT, and
..description as the property .innerHTML.)

When an instance of anObjectType is created, the value of description is
created with the instance. Indeed, the value of description may not be
set with the construction of anObjectType, but it might be added to the
prototype of anObjectType.

But the property .description is not merely read-only. Fetching the value
of .description returns the string which describes the structure of the
object in a meaningful way.

When .description is set with a value of type string, the string is
checked to see if it properly describes a legally formed structured for
anObjectType, and the instance (and only that instance) of anObjectType is
completely re-built: it might possibly be destructed and then re-
constructed, or all properties (but not methods) which involve descendant
objects are changed to conform to the described structure.

The question is, the setting of a string value of the property
..description of object anObjectType does not automatically trigger a
method/methods (or an exception??) for doing something (such as
restructing the object) as a result of the setting of an object property.

JQuery :: Setting Custom Markers With Google Maps API?

Apr 14, 2010

I have a few questions:

1. In the current script, the markers are set to be random within a radius. What would be an easy way to switch from that to using individual markers that I set from latitudes and longitudes? I'm going to be using around 5 way points surrounding an area and can either hard code or throw in some PHP code.

2. In addition to setting my markers, the navigation is done through generated links like "Point 1", "Point 2", and so forth. How would I insert code to replace .html("Point "+i) with something else? I'm guessing to have a main city, have a few towns around it, and the "Point" links are replaced with text I want to use. Probably hard code or use PHP/MySQL to show a zip code or town related to that marker.Here is a sample of the JavaScript code. I only threw in PHP echo tags for the start lat/long and I have that set:

Code:
$(document).ready(function(){
var map = new GMap2($("#map").get(0));
var StartArea = new GLatLng(<?=$latitude?>,<?=$longitude?>);[code].........

Object Properties With Array Syntax - Add Extra Properties To Html Elements

Nov 13, 2009

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.

[variable1] Has No Properties

Jul 23, 2005

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?

How To Access Min And Max CSS Properties From JS

Aug 26, 2006

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?

Method Properties...

I have been working on an Ajax class, but have encountered a problem in IE which i cant seem to work around. In IE i get the following error, referring to the requestChange method.

"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:

Set Multiple CSS Properties ?

Nov 7, 2011

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).

XHTML Transitional looks like this:

What do I have to do be able to set multiple style properties?

I am getting an invalid argument:

Error: Obj Has No Properties

Aug 17, 2005

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

Struts, How To Get At Bean Properties

This what I did find. The form bean will be named the same as the
"name" attribute of the <form-bean> element in the struts-config.xml.

str2, I can get the values on my jsp this way:
