Javascript String Manipulation getting part of a string

I have a url like the following.

http:// myipaddress/folder1/folder2/themes/index.html

Does anyone know of the best approach to always grab whats before and not including /themes/ using javscript string manipulation reg exp techniques. The first bit will regularly be different to the /themes/index.html which is static

you can use javascript split method and remove themes from strings array given by split method and then use join method to concatenate it with your delimeter ('/')

function removeFromStr(str,whatToRemove){
var splitted = str.split('/'),
    filtered = splitted.filter(function(el){
        return el !== whatToRemove;
    });
    return filtered.join('/');
}
test = removeFromStr('http://myipaddress/folder1/folder2/themes/index.html','themes');

console.log(test);

You could use lookahead to get all the texts before /themes,

> var str = 'http:// myipaddress/folder1/folder2/themes/index.html';
undefined
> var patt1 = /^.*(?=\/themes)/gi;
undefined
> var result = str.match(patt1);
undefined
> console.log(result);
[ 'http:// myipaddress/folder1/folder2' ]
