Extracting The Domain Name From A URL Without The Extension?
Apr 19, 2010
I am trying to extract the domain name from a url using javascript but having some problems.
This is what I have:
Code:
var publisherName = document.domain;
if(publisherName.indexOf('www')){
publisherName = document.domain.substr(3,document.domain.length);
}
But it is not working and I am not sure how to rid of the extension Basically, this is what I want: Whether the location being sub domain or not it need to get from somthing similar to[URL]...
Is it possible to capture the domain change event OR domain of the target site in javascript? To elaborate, suppose I am on my site (www.mydomain.com) and if I type www.someotherdomain.com in the address bar, I want to capture the target URL/domain i.e. someotherdomain.com in the javascript code of my site (mydomain.com). I am trying to call sign-off function of my site upon customer navigation to some other site without loggin off. I can not use body/window onUnload function because I have a common layout JSP that would be reloaded for each and every page. So I am trying to capture the URL/domain of target site and check if it is different from teh current domain; Then only I will call my sign-off function to kill the customer session.
I am developing an application which allows a web site visitor to email a page to a friend using the PHP mail() function.
What I would like to do is dynmaically extract the H1 from each page using JS and store this as a PHP session named title. Can I get this info using JS?
I'm slowly discovering the world of JavaScript, so I'm not sure I'm attacking this problem in the right manner, thus if I'm in the wrong newsgroup, my apologies.
What I'm trying to do is extract some news items from a web site. To do this, I'm using Microsoft Word VBA and using the following bit of script:
I found this little script for extracting parameters from a url but wondered what the shortest and most efficient way to do it would be, like the following or via regexp?
function getParameter(paramName) { var currentUrl = window.location.search var strBegin = currentUrl.indexOf(paramName) + (paramName.length+1) var strEnd = currentUrl.indexOf("&",strBegin)
if (strEnd==-1) strEnd = currentUrl.length return currentUrl.substring(strBegin,strEnd) }
I have recently bought the book: JavaScript & DHTML Cookbook. As I opened the .js files with note pad, I asked myself why was the code formated in such a way. The code looks as if it had been produced by some kind of programs instead of a person. I also noticed a lot of little squared zeros; what are those all about?
I have also noticed code formated in a similar way, when viewing some of the source code of the web pages on the MSN web site. If someone knows anything about this machine-like formating, I would love to hear from you.
I've been doing some research on url names. The problem is, I need this code to return like say "index.php", it would return "index". But idk where I went wrong..
The code: <script> var sPage; var sPath = window.location.pathname; //var sPage = sPath.substring(sPath.lastIndexOf('\') + 1);
I allow people to upload images onto my web server. I want to verify each image is less than 50Kb and is an image type, this is what I came up with Verifying the files extension Code:
This might be more of a firefox extension development question but it has to do with JS so i'll ask here in hopes of finding someone with experience in this.
My extension requires the URL of the image that was right clicked. Meaning I have added a new option in the right-click menu when an image is right-clicked that calls a function in my JS file
JavaScript Code: imgSrc ();
This function requires the URL of the image that was right clicked to be passed into it. Does anyone know how I would do that?
What will be the best way to extract dynamically changing information from a web page that holds XML?I have to extract some data from multiple web pages.These sites contain XML code that dynamically reloads (and changes) parts of the page.Since only small parts get a refresh (perhaps 200 bytes every 5 seconds) it wouldn't be efficient (and also might lead to negative reactions from the server) to reload the whole page (about 40k) every time.How could I best determine these updated contents and send them to the program that further processes them?I am familiar with several programming languages but unfortunately have very little knowledge of internet programming.
I'm trying to get some average rgb values from an image in one canvas object and apply them via fillstyle to a rectangle in another canvas object.I have a dropdown that loads an image onChange()="ChangeBaseWood()" into a canvas object. The second canvas object is to be filled with an average color based on the content of the first canvas onClick="GetBaseColor()". For simplicity I've replaced the for loop with just the values of pixel 0,0. Where I think I am assigning the rgb values, the error console keeps reporting that var sample is undefined at the line "var redpart = sample[0].
function ChangeBaseWood(){ var dropdown = document.getElementById('woodvalue'); var woodcanvas = document.getElementById('basewood');[code]....
I've tried various things to assign the redpart,grnpart and blupart but I'm missing something basic.
I have a bit of a problem and as my javascript is a rather poor I'm struggling to come up with a solution. Basically I need to split the variable "#country" into two parts and call the second half as the "this" value for '#int-dc'. Using '+' as the start point end ending at the end of the string.
For instance 'this' returns 12+44 I want to split it to "12" and "+44" the latter (+44) replacing 'this' in the code below.
I'm trying to write code that will extract from an XML file and then display the results. Keep getting a syntax error.
HTML: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html>[code]....
My intention was to access all of the tags (name, genre, and hitsong) in the XML file. Thought that var musicianInfo = xmlDoc.getElementsByTagName("*"); would do that. Then, loop through each tag and display the result.
I have a website in development that has some similarities to Kaboodle.com. I need a FF/IE toolbar button build that can extract images from a website and populate them into my db for display in my pages. This fucntion will work identical to how kaboodle.com works. I had the firefox buttons developed by some freelances, however they lacked the expertise in javascript to make them work correctly.
I need advise on where to turn to so that I can get a quality finished product. I wish to have the work done and I plan to post up a job but I need to know how to word it. Does anyone have experience with this? Can someone point me in the right direction?
I have seen many Javascripts on Internet that checks the extension of the file before uploading. But all these scripts checks the extension when the Submit button is pressed. I want to check the file extension as soon as the file is selected. The script should delete the selected file from the type=file box and display an error message (when a file with the wrong extension is selected).
I am having trouble with retrieving data from an xml file Here is the code I am using can anyone tell me where my problem lies?
[Code]...
as I am very new to Javascript and AJAX I am not very familiar with the process yet and I have not been able to get the xml loaded. Obviously I am declaring this all wrong as I receive the error that load is not a function of xmlDoc!
I would need javascript code to check extension of uploaded file. File upload in not mandatory, but I need script to check extension and allow only JPG, BMP, PGN and other Image files.
This randomising function is like a coin toss, it gives a numerical result and displays it:
function Ran() { var c = Math.random(); return (c < 0.5) ? [0, show0()] : 1, show1()]; }
I want to extract the numerical outcome, 0 or 1, from this and from two other similar functions, sum them, and then run more functions based on the possible sums.
What is the syntax for getting to the numbers? something like
