JSUnit Testing
Mar 9, 2006I'm trying to get JSUnit to work - I've tried everything I can think
of, but I can't get the simplest of tests working - example 1 of the
jsunit homepage - Both on my server and locally, nothing happens after
clicking run - or if I'm lucky, a window pops up, blank, other than the
heading "Tracing - JSUnit".
Testing If A Function Has Already Been Run?
Dec 4, 2010I had a rethink about my problem discussed in this [URL] thread, where the function won't run properly a second time if the page hasn't been reloaded. That one appears not to have a solution, and I was thinking that a reasonable plan B is the following:
a) test if the function has already been run since the page was loaded
b) if not, run the function
c) if it has, reload the page with the onClick, then run the function automatically on reloading.
the problem I envisage is will the page "remember" to run the function once it has been reloaded?Of course, it would be simpler to do it running the function automatically once the page loads, then just reloading if the test comes back that the function has been run already, but that wouldn't work for the first time you visit the page - it would start running straight away, whereas I want it to wait for that first click. Here's the page [URL] I'm working on, if you want to have a look.
Testing Javascript
Jul 12, 2005I was putting some javascript in a form and doing my usual testing and swearing when the javascript did not run without an error message of any type and reverting the code back until it did run and adding code til it didn't.
Then it hit me - isn't there a better way - doesn't someone have a program or utility that will help debug Javascript ???
As I'm doing Javascript it is much harder to decode than the 30 year-old Fortran programs - they typically gave a line number and variable name that was missing.
When I did Basic before Visual Basic, the editor identified errors in real time as we typed. What is available for Javascript?
Testing On Different Netscape Versions
Jul 23, 2005If I have to test my code on different Netscape versions, can I download and run those versions on the same computer or will it create conflicts? And if I had to test only one version which one should it be - which one has the most common elements to all the versions?
View 3 Replies View RelatedTesting To See If A Window Is Open
Jul 23, 2005I am trying to check if my new window is open and if it is change the url.
This works until I use the x in the corner to close the window. At that
point i get an error when i try to open the window again. I believe that it
is because newWindow is still active. How do I close newWindow when it is
unloaded or closed by the x. If this is truely the problem.
function openWindow()
{
if (typeof (newWindow) == "undefined" || newWindow.open == false)
{
newWindow = window.open("http://www.yahoo.com","","width=400,height=400");
newWindow.focus();
return false;
}
else
{
newWindow.location.href = "http://www.msn.com"
}}
Here's my solution, seems a little redundant though.
function openWindow()
{
if (typeof (newWindow) == "undefined" || newWindow.open == false)
{
newWindow = window.open("http://www.yahoo.com","","width=400,height=400");
newWindow.focus();
return false;
}
else
{
newWindow.close()
newWindow = window.open("http://www.msn.com/","","width=400,height=400");
newWindow.focus();
return false;
}}

JQuery :: Testing The First Character Of A H1?
Sep 2, 2009determine what the first letter of a selector is? For example, if the very first letter of a paragraph is a quote (or a ‘ , or a “ , etc) I would like to apply a negative text- indent to the found paragraph so as to replicate "hanging quotes" that are commonplace in the print world. The code I've come up with is: $("p:contains(“), h1:contains(“), h2:contains(“)").css({'text- indent':'-0.3em'}); but this grabs any p or h1 or h2 that *contains* an opening curly quote; not what I'm looking for. I need it to select paragraphs that *start* with the opening curly quote. Incidentally, I could not get this to work when I was searching for $ ("p:contains(“)... but it worked when I entered an actual opening curly quote in the search (as above top). I tried both single and double escapes too.

Testing For CSS3 Capabilities
Mar 27, 2011Is there any way to detect through Javascript whether a browser supports a particular property of CSS? I am experimenting around with CSS3 and I would like to be able to detect whether the browser understands what to do with a particular setting, as in "elementRef.style.newCSS3_property = '3px' " I have heard, although I do not know if its true, that there is some way to access whether the browser knows what such a declaration means.
Does anyone out there know how to do this?
Testing For Existence Of Element?
Apr 13, 2010I have the following code:
Code:
<script language="javascript">
<!--
// Max number of items to show/hide
[Code].....
Which is designed to hide all but one of a group of DIVs with consecutive IDs in the form "listings_stations_<number>". The problem is, I won't know how many of these DIVS there will be. I know a maximum possible number though.
The script as-is works, but obviously throws up errors trying to get handles to non-existent elements/objects. How can I check an element exists before getting and setting style properties for it? I'd like a solution that works for all three browser-types the script currently works with.
Help Needed With Event Testing Script
Jul 23, 2005I'm trying to check for this bug with the following script and it
*seems* to work. In IE it reports "bubbling" and in Firefox "not
bubbling" but I really have no direct way to confirm the Firefox
results until the bubbling bug is fixed.
Basically the test script assigns an onscroll event handler to a
textarea and then scrolls the textarea down then back up, checking to
see if a the event handler works (assigns the "bubbling" variable a
"true").
I had to code things with a few settimeouts otherwise Firefox, unlike
IE, wouldn't display the down then back up scrolling of the textarea.
Which may have been a problem.
Lacking a "debugged" Firefox browser, is there some further (indirect?)
tests and/or rational that would support or discredit this script as a
valid onscroll event check? ....

Proper Structure When Documenting Testing?
Nov 6, 2011So firstly this is likely not in the right place at all, as it's a bit OT but I figured it's the best place to ask. I have to document 4 different tests to my code; what structure should I take when doing this?
I was thinking:
* State the aim of the test
* State the inputs, and what I believe the output should be.
* State the actual output, and whether this positively or negatively affect my code.

Bug Testing In IE8 - Invalid Argument Error ?
Jun 24, 2011I'm testing my webpage in IE8. In firefox it looks and runs greag, but in IE 8, one issue I'm having is this: I have a button that opens a popup window. Works fine in Firefox, but I get 'invalid argument' error in IE8 and the window does not open. I've enabled at a whim some scripting things in the Internet Options.
Here's the code. The "invalid argument" occurs on the window.open call.
In addition, is there any way to have that tile I've given it, "my Site..." appear in the window header? Right now it's not appearing at all in either browser.

DHTML Floating IFrame - Help Testing/correcting
Jul 23, 2005Don't know if this is the right place to post this JavaScript issue. If not, could someone point me in the right direction please.
I am trying to make a "cross browser compliant" floating iFrame. Not real fancy, just load, resize and move.
But, I do not have the browsers, OSs and different machines (like Mac) to test the code on.
So I need some help to see where this basic example of works and does not
work. That is, some help testing and correcting it if possible.
So far, I know it works on these: IE6 Win98, IE6 Win2000Pro, Netscape 7 Win200Pro, FireFox XP Home & XP Pro and IE6 XP Pro. But what about, PC IE5, IE5.5, Opera, and Mac (all), as well as others I've omitted.
