Detect If "style" Object Is Available?
Sep 2, 2009We all know you can test if an object exists in JS. Example:
Code:
if (document && document.all) {
}
However, I need to find if the style object exists. This "style" object to be exact:
Code:
document.getElementById("test").style.display = "none";
Can I find if the style object works without using getElementById on a specific object?
Detect URL & Detect Something On Page & Show Content Accordingly?
Feb 14, 2009Can Javascript be used to detect a certain url and then "not" write some html according to that url and also detect something on the page and "then" display some html?.
Example: I'm working on a volusion site that uses asp. There's basically only one page that's changed dynamically. I would like to display some html when and only if the cart has any items in it. But also not to show up on the check-out pages.
The page dynamically displays "Your cart has 1 item in it..." when the visitors puts something in their cart.
So could javascript detect when this is displayed then write some html and then also detect if the url is showing the cart and then not show the html?

View 3 Replies View RelatedIE ResponseText Is Empty
Feb 24, 2011I'm trying, to fill a table with data I receive from a Servlet. In Chrome everything works fine. But when I try the app on IE the responseText is allways empty. The following is my JS code (using prototype):
function updateToDeleteTable(){
var url = 'getDefHidConFechaInsercionMayor?plantacion_id='+$('plantacion_id').
options[$('plantacion_id').selectedIndex].value +
"&fechaDesde="+$("dateSelect").options[$("dateSelect").selectedIndex].value;
[Code].....
I know the servlet returns a correct text, because when I enter the request uri in a new IE tab it returns the appropiate html code.
Allso when I check the variable response in the IE JS debugger the resaponse of the servlet is 200 (OK). I realy can't think of anything I'm doing wrong, exept, that maybe there is a size limit for the responseText.

Apr 24, 2009I need a simple script that will check onclick if the user has entered something into the input text form. If they haven't then just alert that you must enter something to search for a term.

Hiding A Div If A Variable Is Empty ?
Sep 30, 2009I'm using a Javascript gallery (runs on Prototype library) that populates a caption field if the user has entered a caption for an image.
I need a little bit of code to hide the caption's div entirely if the user hasn't entered a caption for a particular image (var 'caption' is empty).
It's the bottom-right white box below the image, you'll have to click over to the second page of the gallery (NEXT) to see an example of an empty one that I want to hide:
[url]
Here's the CSS:
Here's the HTML:
I'm sure this isn't that hard, but I've spent more time trying to get that caption box to hide than setting up the gallery.

The problem is when it loops around it seems to strip everything from the page HTML, HEAD, BODY tags and everything inside of those and just puts the value of the elements from the xml file onto the page. My question is, am I able to perform this loop and keep the rest of the contents of the page intact? I've been trying for most of the day and I can't get this working.
