I want a javascript variable to be what is behind the ?url= in the url..
for example: The current url is
http://mywebsite.com/test/index.html?url=http://www.google.com/
So the variable has to be http://www.google.com/ .
I tried this, but it doesn't work… why ?
var url = document.URL ;
var appname = url.match(?url=(.+))[1];
Thanks.
I think the following will work for you:
function querystring(key) {
var query = window.location.search.substring(1);
var keys = query.split("&");
for (i = 0; i < keys.length; i++) {
var values = keys[i].split("=");
if (values[0] == key) {
return values[1];
}
}
}
var appname = querystring("url");
alert(appname);
Try this:
var regex = /\?url\=(.+)/;
var appname = regex.exec(url)[1];
or even simpler:
var appname = /\?url\=(.+)/.exec(url)[1];
var url = location.search.match(/url=([^&]+)&*.*$/)[1]; // http://www.google.com/
location //location object
.search //the search part in location
.match //return string according to regex given
[1] //second result (result in parenthesis)
//--------Use in a function---------
function getQuery(txt){
var result = location.search.match(new RegExp(txt + "=([^&]+)&*.*$"));
return result === null ? undefined : result[1];
}
location.search
