I have spent the better part of a day trying to figure this out, but cannot get it to work. What I am trying to do it reverse the background color of a cell with the font color and vise-versa. However for some reason I cannot get JavaScript to obtain the current assigned value of a CSS style. Code:
View 3 RepliesIs it possible to get the Server IP Address from Javascript
ie., when the user types "http://10.0.0.10/main.htm" in the web
browser, i need to retrive the value of the IP Address(10.0.0.10) from
my client side javascript.
I have a textfield and you of course you can select text...
When they hit the bold button I want it to obtain the selected text and
bold it, the hard part is trying to figure out if javascript can even
OBTAIN selected text?!?!
I can do this in java if I have to, I know java better than javascript,
it seems as that is the only way to do it from looking online.
I want to submit a form but it requires a code that is generated by every session (not the php session type). What i'm looking for is for a piece of code that fetch the session code and set it as a variable that can be called in JS.
I know that exists in PHP the cURL that it's able to retrieve the code and set it but i don't know how to start...
Here's the scenario, website A wishes to include a JS file from website B. Is there anyway the script hosted on website B, can know its own url?
View 4 Replies View RelatedI am working on a firefox extension. The job is to sit in the status bar and as I type into any form on any webpage, listen for keyboard events, then modify the key pressed by mapping it to some foreign unicode character and then sending it to the form in focus.
As I see it, there are two ways I can achieve it.
1) Capture the event, modify it and then send it and not be concerned with the form in focus.
2) Capture the event, prevent default action., find a unicode mapping for the key pressed, find the form in focus and based on the type of form, call a method to explicitly insert the mapped character at the cursor position.
Right now I am not able to find a way to do either. Once I get the focused element, I can do something to it. But I am not yet able to get that. I even tried document.activeElement, but it doesnt seem to work in firefox.
I know this is possible to get data from a specific cell in a table on your site :
But is there any way to replace 'document' whit an external url so you can obtain data from a specific cell in a table on another webpage. Maybe like this (I know this isn't even close to be able to work...):
I'm actually not sure if this is even possible whit javascript. If not, do you know any php script whish does that job?
I;m looking for a way to obtain key names from a JSON object:
eg
"options": [
{"Option1" : ["Value1", "Value2"]},
{"Option2" : ["Value3", "Value4"]},
{"Option3" : ["Value5", "Value6"]}

Prototype seems to have a keys method which would achieve what i'm looking for. There are also a few pages which attempt to address the issue with JQuery, such as: [URL] However i was only able to retrieve the numerical index of the array elements using these methods (vs their name).
How can to obtain length of string variable, for example if I have:
var msg = 'hello world!';
Does it exist a method to count string characters?
How can I obtain content of cascade style, using javascript? I know, there's a code
document.getElementById('id').style.border='5px solid blue';
For example, but I need to do reversed operation, not to change style, but obtain it.
I want obtain the path of an outlook message for save it into database.
View 1 Replies View RelatedIs there a way to obtain the DIV you are currently hovering over using Jscript?
Basically I have ten thumbnails that I'd like to change the borderColor for using onmouseover. Instead of having to specifically create a DIV for each thumbnail (#tmb1, #tmb2, etc.) and then having to attach a separate function to each one (document.getElementById("tmb1").style.borderColor = "#660000") I'd like to be able to detect the DIV the mouse is currently over and change the borderColor of that.
I have over thirty pages, each with 10-15 thumbnails, which is why I'm trying to come up with something more generic.
I need to chop up a string to obtain just the filename of an image. Lets say the image source is /images/thumbs/image.jpg. Using the DOM I have the source of the image in a variable called 'source'.
What I want to do is manipulate it so that it just returns the file name image.jpg. How can I achieve this? I tried split() to see if I could split it into an array using the / as a separator, but this didn't work.
I want the client to be able to obtain the http headers for a website I have. Mainly the WWW-Authenticate information (http digest). None of the scripts online have this. Someone said that on the server side I'd have to generate the code for the client, but how would I go about doing this?

I am using Ben Alman's JQuery resize plugin in order to obtain the varying computed width of an element when the window is resized (the element in question is a page wrapper that exhibits the expand-to-fit behavior of a block box, and it's computed width is obviously influenced by the resizing of the window. Essentially, what I need to be able to do, is to reference a variable that is defined in a .resize() function ('width_page') in a seperate .each() function.
[Code]...
I now understand that variables can't cross boundaries like in the example above, which leaves me a little stuck. I also understand that this is specific to the context of the .resize() function, and that it can't be taken out of it without using an element selector. Is there some way I can call the .resize() function in my .each() function?
I am trying to use Jquery to create an "add" button, upon which you click and then you obtain a new tab on your page. But it's hard for me to understand how to do that because the language seems complicated. I found this :
[Code]..
My understanding had been that $.css("width") would return the original user selected style, eg "100%" or "10em", and $.width() returned the computed width, always in "px". Not so, following the code through for .css(), it calls something called getComputedStyle and the only difference between the two functions turns out to be a post-fix of "px" on the .css() result - not very useful. I need to know whether my user has called me with a proportional dimension, or a fixed one. How to tell with jQuery?
View 1 Replies View RelatedI need to get the value of the cells in the xml file. I have managed to obtain the row id below.
xml file:
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"

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.
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:
two possibilities or the attribute type of script:
text/javascript (the one i usually use) application/x-javascript
what are the differencies between both?
depends on the html content?
for example html 4.0.1 versus xhtml 1.1?
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>

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