How to replace string from a particular index to end

I'm trying to replace a string from a particular index to end

I have different string inputs with a link at the end I want to delete that link

for example I have :

Hello world ! this is my website link http://www.lo.com

I want to delete the link to get only :

Hello world ! this is my website link

Code :

Var message = "Hello world ! this is my website link http://www.lo.com";

How to do that in Javascript ?

Here's how you do this:

message = message.substring(0, message.lastIndexOf("http://www.lo.com"));

(obs: use substring instead of substr because substr is deprecated now)

Or if you want something more general, like removing all hyperlinks at the end of the message:

message = message.replace(/(\s*(http|https):\/\/.*$)/,"");

Have fun.

function removeLinks(text) {
    var urlRegex = /(https?:\/\/[^\s]+)/g;
    return text.replace(urlRegex, ' '); // replacing with space
}

var text = "Hello world ! this is my website link http://www.lo.com";
var corrected = removeLinks(text);
alert(corrected);

Just call the function removeLinks() which strips off the web links

var str = "Hello world ! this is my website link http://www.lo.com";

var idx = str.indexOf("http://");

str = str.slice(0,idx-1);
console.log(str);
