you know of anything like this?

Javascript Editor To Include It In Eclipse

Aug 20, 2007

I am looking for a good - if not THE BEST - Javascript Editor
available, prefarably to include it in Eclipse.

I found Aptana, but it still seems to be buggy, it had problems with
special german characters.

The best would be an editor similar to the Eclipse Java editor - I
want to be able to click on a function or variable to see how and were
it was defined..

Eclipse

Oct 30, 2005

I anyone using Eclipse? If so, can you give me a clue to get started.
I keep reading about how good an IDE it is, but it does not seem to
help with Web stuff (CSS/HTML/JavaScript). I downloaded a variety of
plug-ins, but it just seems like a hard to use straight text editor.
What am I doing wrong? Code:

Whats Wrong With This Wait Function?

Jul 20, 2005

I have tried to write a wait function but it seems like it will not brake the while loop. I tried two different solutions. Can anyone tell me what I am doing wrong, and come with another suggestion? If I call the function like this: wait(500); it should wait 500ms right?

function wait(time) {
while(1){
setTimeout("break;",time);
}
}

function wait(time) {
var flag=0;
while(flag=0){
setTimeout("flag=1;",time);
}
}

Dynamically Filling In A 3rd Value In Select Pulldowns Depending On Whats Entered In The First 2

Jul 20, 2005

I have 3 select pulldown boxes where a user will select a year (either
2002 or 2001), a week (one thru 52), and a database (short data or long
data). But if a user selects a week that is less than 4, the 3rd select
pulldown will only show the choice of "short data", as they will not be
able to select "long data". Is it dynamically possible in javascript to
program a third pull down in this fashion?

Autocomplete AKA Google Suggest Made - Whats The Best Thing To Call Database Or Xml

Mar 28, 2009

So I have a nice little hand rolled Ajax call to my server pulling a list from the database and displaying it in a drop down list dependant on the user input. Aka Google suggest. I am wondering if the quickest way to do this is to call the database each time with Ajax and search the results with the input, or to write an xml from the database and search that. Then when the Database is updated rewrite the xml file.

Am I underestimating MYSQL again? Or not, and I feel it would be good practice to write the xml file because it will essentially mean a lot less database calls. But I don�t know how fast searching an xml file would be in comparison to a db call. The results from the database are say 500 entries anywhere between 10 - 100 characters each. I want to know A. The best way to do this B. Lets say the site will have pretty high traffic so I am looking for it to be as tweeked as possible. I can test but thought at the end of my week it was worth seeing what peoples advice is.

Create An "Escape Room" Game With Eclipse?

Oct 14, 2011

I have a website assignment we've been given the following criteria:

This assignment aims to satisfy assessment of the following module requirements:

1. create web pages which use the range of facilities provided by XHTML,

2. format XHTML content using CSS,

3. write simple JavaScript applications,

4. validate XHTML pages and their CSS,

5. understand the importance of usability in developing Web sites,

6. work cooperatively in a small group to accomplish a complex development task

It's got to be a 100% client based interactivity site e.g. NO server programming such as PHP or any SQL databases.

Dynamically Writing Html/javascript From A Javascript Function

Jul 23, 2005

I'm working on some code and am running into brick walls. I'm trying
to write out Javascript with Javascript and I've read the clj Meta FAQ
and didn't see the answer, read many similar posts (with no luck
though), and searched through the IRT.ORG Faqs
(www.irt.org/script/script.htm).

The Javascript is designed to open an popup window and then inside that
window call another script which will resize that window. There may be
another way around this but the reason I tried this approach initially
was that I wanted to call the onload handler in the popup window to
resize the image only after the image had completely loaded. I've had
some code in the primary Javascript file (showimage.js) before that
works if the image has been cached but on the first load, it doesn't
resize properly which tells me it is probably because it is trying to
resize the window based on the image size but it isn't completely known
at that point. So I removed that code and tried placing the resizing
code in the second Javascript file (resizewindow.js). BTW I've tried
other code to open a popup image and automatically size it ie Q1443 at
irt.org but that doesn't do exactly what we need.

Even if there is another way to do this with one file, I still want to
figure out why this isn't working in case I run into it in the future.

I thought what I would need to do to use document.writeln to write
Javascript would be to escape any special characters and to break
apart the script tag ie

document.writeln('</SCRIPT>');

would become

document.writeln('</SCR' + 'IPT>');

I have a HTML page and 2 Javascript files. All files are in the same
directory and have permissions set correctly.

Here are the 3 files (keep in mind wordwrap has jacked up the
formatting):

index.html
----------
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Test</title>
<SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1"
SRC="showimage.js">
</SCRIPT>
</head>

<body>
Click the house<BR>
<A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG
SRC="house1thumb.jpg"></A>
</body>
</html>


showimage.js
------------
function newWindow1(pic,sitename)
{

picWindow=window.open('','','width=25,height=25,sc rollbars=1,resizable=1');
picWindow.document.writeln('<html> <head>');
picWindow.document.writeln('<SCR' + 'IPT type="text/javascript"
LANGUAGE="JavaScript1.1" SRC="resizewindow.js"></SCR' + 'IPT>');
picWindow.document.writeln('</head>');
picWindow.document.writeln('<body onload="resizewindow();">');
picWindow.document.writeln('<img src=' + pic + '>');
picWindow.document.writeln('</body> </html>');
picWindow.document.close();
}

resizewindow.js
---------------
function resizewindow()
{
// Do resizing here.
// Right now this isn't being executed
alert("resizing window");
}


Can anyone provide some pointers as to why this javascript is failing?
I'm using IE6 on Win2k and when I click on the image to open the popup
window, it does open the window but it is white with no content and the
system immediately goes from about 4% CPU usage to 100% and
consistently stays there until I kill that window with the task
manager.

DOM Javascript - Imbed Javascript In Dynamically Added Row

Jul 23, 2005

Attached is a simple HTML file that adds and delete rows. In the add
row function I set an attribute "onClick" this triggers the
testMessage() function. When I try this in Firefox it works just fine
however on IE it just refuses to work.

What is interseting is the ROW that already exists has a similar
'onClick' event which works when the page is loaded, but subsequent
"row" additions to the table to not work in IE. Code:

Javascript Function Has No Properties In Javascript Console

May 25, 2005

I'm getting errors in Firefox everytime I try to run this frame resize code, but it works fine in IE. I can't seem to figure out what the problem is with it.

The error is: Error: theFrame has no properties
Line: 8

The line that the javascript console is showing an error for is in italics.

code from page:

<html>
<head>
<script type="text/javascript">
var defaultCols="100px,*";
var hiddenCols="0px,*";
function ShowHideMenu(){
theFrame = document.getElementById("framed");
if(theFrame.cols == defaultCols) theFrame.cols=hiddenCols;
else theFrame.cols=defaultCols;
}
</script>
<frameset cols="100px,*" name="framed">
<frame src="lframe.htm" name="frameMenu">
<frame src="mframe.htm" name="content">
</frameset>
</head>
<body>
</body></html>

Come someone let me know what I'm doing wrong here?

'Javascript Anthology' Or 'Professional Javascript For Web Developers'?

Mar 30, 2006

I'm already past the basics of Javascript, and i need something that takes me to the other level and teaches me the new technologies and cool stuff (drag&drop, AJAX, OOP in javascript, maybe XUL...etc). So far i found these two books:

1. Sitepoint's "The JavaScript Anthology: 101 Essential Tips, Tricks & Hacks".
2. Worx's "Professional JavaScript for Web Developers (Wrox Professional Guides)"

Both seems to cover very insteresting topics, but i can only buy one of them. So which one do you suggest?

and by the way, i've read the sample chapter 5 of Sitepoint's book, and it seems like the author(s) just put the solutions/codes there and let you figure them out on your own. Is this how the rest of the chapters are?

Nixing Javascript Via Javascript: Pseudoproto?

Jul 23, 2005

This is a question about defensive web browsing. Ocassionally I run into a page whose JavaScript does something that I find obnoxious. I would like to turn off JavaScript only for that page (instead of disabling it globally). It would be cool if there were some way to do this through a "bookmarkable" JavaScript snippet using the javascript: pseudoprotocol. Does anyone know any trick to do any of this?

Extract Links From Javascript (not Using Javascript)?

May 26, 2006

I am looking for a method to extract the links embedded within the
Javascript in a web page: an ActiveX component, or example code in
C++/Pascal/etc. I am looking for a general solution, not one tailored
to a particular page/script.

Hopefully, the problem can be solved without recreating a complete
Javascript interpreter. Any ideas?

AJAX, Eval(), And Javascript Within Javascript

Apr 28, 2006

Ok so, this is my purpose:
- to be able to load asynchronously (via AJAX) some javascript ads (like google's or adbrite) so as to make them be loaded in the background, then update the page after the ads have loaded via innerHTML

Why?
-Because 90% of the time in my newer sites, javascript ads are the major offender in terms of speed of page rendering

My problem:
Via ajax, I can call a php file that retrieves some javascript and outputs it, XMLhttprequest returns those javascript lines, but they don't render in the page, since they miss the whole page loading, and are apparently not parsed
For example, let's say I call a php file via ajax, and it returns the output into a variable named "text" containing "document.write('hello')"
if I use xxx.innerHTML=text, nothing happens

My 1st solution:
Passing those javascript lines to eval() [like eval(text) ], but this produces a second problem, that I couldn't solve (probably because of my lack of knowledge in javascipt):
if I eval the code, it deletes my current page and renders a new one
for example, if I parse a document.write, my page disappears, and a new one is rendered with the document.write text

What I want is basically to make that "document.write" appear inside a div in my page, adding to the content (and not overwriting the whole page), much like what happens when using innerHTML

Is this even possible? How would you go about it?
I tried xxx.innerHTML=eval(outputfromphpfile) but it overwrites my whole page...

JavaScript Withing JavaScript ?

Just a quickie: is it possible to place javascript within javascript? The following is the code I am using to create a pop-up for a picture gallery. I would like to place a banner from a banner exchange in bold under each photo. When I use the code below I get an error message:

<SCRIPT language=JavaScript>
<!--
function openpic(pic_name) {
myWin= open("", "displayWindow", "width=640,height=510,status=no,toolbar=no,
menubar=no,scrollbars=yes,resizable=yes,alwaysraised=yes");

myWin.document.open();
myWin.document.write("<html><head><title>" + pic_name + "</title>");
myWin.document.write("</head><BODY><center><TABLE CELLPADDING=&#390;' CELLSPACING=&#390;' WIDTH=r'>");
myWin.document.write("<br><img src=kate/image"+ pic_name + ".jpg><br>");
myWin.document.write("<br><br><BR><br><BR><br><BR>");
myWin.document.write("<script language='javascript' type='text/javascript' src='http://www.linkbuddies.com/ad.go?id=134039+2&n=3'></script>");

myWin.document.write("</center></body></html>");

myWin.document.close();

Javascript Inside Javascript

Dec 12, 2005

Basically, on one of my sites I'm running adsense and today I added Chitika. The problem is, I can't run those type of ads through my banner advertising program.

The banner advertising program calls the banners/HTML from code like this:

<script language=JavaScript src=http://www.mysite.com/advertise/abm.asp?z=1></script>

And using that program I'm able to either choose a banner or HTML I want to display when that code above is used. It displays HTML ok... but when I try to run an ad of either adsense or chitika nothing displays on the page. The code that would be called is:

<script type="text/javascript"><!--
*Chicika code in here*
//--></script>
<script src="http://xxx/xxx/mm.js" type="text/javascript">
</script>

So... it looks like I can't have javascript call another javascript to display on a page. My question is then... how can I edit the above to make it work or how can I work around this problem? I'd really want this to work with Chitika and not so much with adsense... but it appears both Chitika and Adsense use similar javascript code.

Javascript V ASP

Jul 23, 2005

does a client side script always need a server side script in order to
function?

how can i get my javascript application to send the details of a user
filled form to me without having to have a server side script?

if i have both server side and client side script in a web
application, will the resulting application run as a client or server?

i know i probably haven't made much sense, but the problem is that i'm
trying to make sense of it all.
