I'm trying to use variables in the following way in javascript:
var prop;
prop = 'innerHTML'
alert(document.getElementById(id).prop;
I've tried it that way, and it doesn't work, but is there a way to reference a variable in a property like that?
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.
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?

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.

View 1 Replies View RelatedI have a program written in Javascript and fully functioning which takes a user-selected directory name and then displays all the photos in that directory in a certain format.
I am now wanting to expand the program to allow users to optionally enter their own strings and the program will use all the photos from www.flickr.com which use that string as a tag.
I have a PHP interface to flickr (called PHPflickr) which collects all the relevant photo urls. I now need to get these images back into my Javascript so I can process them using the existing functions (rather than rewrite all my functions in PHP code and have two sets of functions in the program). I found on another thread a means to do this for a date variable:
var jsArray = new Array(
<?php
$length = count($monthDataArray);
for ($i = 0; $i < $length; $i++)
{
echo '"' . addslashes($monthDataArray[$i]) . '"' . (($i < $length - 1) ? ',' : '') . "
";
}
?>
but being completely new to PHP I'm not sure what "addslashes" might be or what formatting will be necessary if I am starting with an array of urls. Code:
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?

I use getElementById in my first function to draw a line inside a <div> box like this:
function line(x1){
var cd=+1;

var division = document.getElementById("line1");

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:

The full(?) javascript for this function is:

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;
