Check The Current Element Set Style.display?
Feb 18, 2010
I am using AJAX + JSON to construct a HTML code, which physicaly does not appear on my page, but after is created and put in a variable I display it with innerHTML. Then with another on e function, I tell some of the <tr> to get style.display = 'none', which is working properly! Then I want to check which of them are currently invisible an d for that purpose I use:
Code:
for (p = 0; p < rows.length; p++) {
if(document.getElementById(rows[p].id).style.display == 'none') {
alert(rows[p].id);
}
}
where rows is a define array with getElementsbyTag with all the <tr> - s. Then what happens is really strange - I am getting alerted ALL the <tr> ids, including the currently visible, and, then they dissappear, (as if I have told them to make them style.display = none, which I haven't)!! I have tried also with currentStyle instead of style, but the effect is the same.

Code:
test.div.style.backgroundImage=test.div2.style.backgroundImage;
It works if I specify the actual background image within the function, so I know the image is there, and I know it's been properly assigned to div2, but div1's background image doesn't change.

I have a situation with setTimeout where I need to check the number of milliseconds remaining so that the program logic can decide whether to follow through with the operation or delay it a few more seconds.
Pretty much this is used to reduce lag on the user's end so that if they are in the middle of typing it won't execute the timed function unless they have stopped typing for a few seconds, making it safe to perform the operation (in the background) without interfering with their user experience.
In any event, there doesn't seem to be a native way to check the current progress or remaining millisecond count on a setTimeout. That is, unless I just haven't been able to find it.

I'm looking for a JS code that will check the current browser and then use a different background image accordingly.Mainly for browsers like Flock and etc. that aren't yet CSS3 friendly (background-size:cover; etc.)I'm not looking for an alternative to CSS3, because, well, I like it! Just a way to check if the current browser is CSS3 friendly.[EDIT]I just started reading an article about Object Detection ttp://www.quirksmode.org/js/support.html). Seems like a better alternative to browser detection. However, how do I use JS to check if the browser supports a CSS3 statement???

I have the following function in my attempt to build a 'treeview' It should (and does in Firefox) display an indented <p> tag (css indents it). The problem however, it doesnt work in IE. When this function is fired IE builds a VERY small <p> tag without any content in it... I think the problem might by caused by style.display but I don't know how to solve it.
function r_treeview(test, path) {
// get DIV element
elm = document.getElementById(path);
pid = 'sub'+path;
// add paragraph (p) to contains var test
if (!document.getElementById(pid)) {
var pTag = document.createElement('p');
pTag.setAttribute('id', pid);
pTag.className = 'subp'
pTag.style.display = 'block'
elm.appendChild(pTag);
pTag.innerHTML = test;
}
}

Is there a good library available (jQuery or stand-alone) that allows you to customize the troublesome form elements that aren't very receptive to CSS across browsers?
I was looking to try to match drop downs, radio buttons and check boxes with the same look and feel as everything else.

Situation:
A (rather long) page that contains a lot of divs.
Some are visible (display:inline) at a certain time, other not.
The javascript is responsible for divs to be visible or not.
Question:
If the browser is displaying some divs, and the user gives a printcommand
for the page, can I be sure only the visible parts are printed?
On my machine this is working fine (W2000/IE6), but I hope it will work on
all setups that support display:inline and display:none (= every modern
browser I think).
Could this give problems for different printers/printdrivers?
Or can I trust that if the browser can handle divs right, it will send the
correct commands to the printer?

I have built an expandable menu that displays some categories and subcategories. The menu is populated from a MySQL DB and I'm using PHP to configure the data for the Javascript menu. All of this works correctly.
There are 2 options when using the menu.
1. Click the arrow icon next to the category option. This opens the subcategories for that category while remaining on the current page.
2. Click the category title (text link). This brings you to the category page.
When a user clicks the category title to go to the category page, I want the subcategories for that category to be open when they get there.
Everything seems to be working correctly, until I get to the line to open the subcategory.

<head>
<script type="text/JavaScript">
<!--
var whichOpt='select'
function showOption(which)
{
//First hide the currently displaying menu.
document.getElementById(whichOpt).style.display = "none";
//Determine what the new selection is.
whichOpt = document.getElementById(which).options[document.getElementById(which).selectedIndex].value;
//Show the newly selection menu.
document.getElementById(whichOpt).style.display = "inline";
}
-->
</SCRIPT>
</head>
Code:
<select class="g4" NAME="bonustype" id="bonustype" style="width:180"
<option VALUE="select">Select an option</option>
<option VALUE="signon">Sign-on bonus</option>
<option VALUE="refer">Refer a friend bonus</option>
</select>
</div>
<table width=190px align=center><tr><td><div id="select" align=justify class=red>After selecting a bonus type, the criteria relating to that bonus will appear here.</div></td></tr></table>
<div id="signon" style="display:none;">SHOW SIGN ON CRITERIA</div>
<div id="refer" style="display:none;">SHOW SIGN ON CRITERIA</div>
However, at present I cannot get the 'signon' or 'refer' div's to appear. When the php page is loaded, 'After selecting a bonus type, the criteria relating to that bonus will appear here' will appear on the screen. When I select a different option for the 'bonustype' combo box, the writing will dissapear but nothing will show up instead. When selecting 'Select an option' again, the writing that appeared at the start does not show up.
therefore I take it that the javascript is not working correctly (i.e. not changing the style display option contained with in the div's). But why does the 'After selecting a bonus type, the criteria relating to that bonus will appear here' disappear when a different option is selected, but not appear again?

I've browsed through past usenet archives, but can't seem to come across quite the javascript I'm looking for. I'm looking for a simple javascript that will display the date as such:
May 17
So basically, just displaying the current month and the current date. But I would also like the ability to backdate by one day, two days, etc.. So the next date might look as such:
May 15
Which would be two days earlier than today's date, but in keeping with the same format.

I have a project to do for a kind of business directory and while I already have it designed I'm stuck on one aspect of it. As it stands, you select a category and then get the results in a nice little invisible table with colored rows. Now, I can create any table I want through the use of a hidden Javascript function that contains the information (No, I'm not worried about updates) and then creates the table.
The problem I have is this. If someone changes the category or puts in a partial name or full name, how can I delete the currently displayed results and then show only the results for the new search? And how can I do this consistently? The problem I have almost sounds like a problem that should be solved using PHP but it doesn't sound so complicated that it couldn't be done in javascript either.

I have a element that uses a class, like:
<style id="abc" class="myClass" onClick="test(id)">....</span>
The function:
function test(id) {
alert(document.getElementById(id).style.backgroundColor);
}
Why doesn't this work? It returns nothing, but the class, which the element uses, has a background-color value set... ?!?!?! Am i missing something... ?

I am working on a little javascript project, and I need to get an arbitrary element's style information.
For instance, I want a method that you can pass a reference to an object, and for instance, find the current css height property that applies to it, no matter where it was declared. I don't mind it returning a null value if it wasn't set anywhere, but if it's coming from some css class or some css id or some locally defined style, I want to know what is being expressed.
If I just try el.style.height, it only lets you know what the height is if it was explicitly defined in the style tag.
