I have a request url / string var like http://ip_or_url:4773/image_renderer.service?action=resize&from_format=png&from_url=http://ip_or_url:4773/my_file.user.file&to_format=jpg&w=1920&h=1200 It looks terribly scary. I wonder how to extract from_url=http://195.19.243.13:4773/my_file.user.file argument pair from it and then extract relative file url from that pair value my_file.user.file ?
With pure javascript. It'll return an array of key/value pairs.
ReplyDeletefunction getUrlParts(url){
// url contains your data.
var qs = url.indexOf("?");
if(qs==-1) return [];
var fr = url.indexOf("#");
var q="";
q = (fr==-1)? url.substr(qs+1) : url.substr(qs+1, fr-qs-1);
var parts=q.split("&");
var vars={};
for(var i=0;i<parts.length; i++){
var p = parts[i].split("=");
vars[unescape(p[0])]= p[1] ? unescape(p[1]):"";
}
// vars contain all the variables in an array.
return vars;
}
Let me know if any of your test cases fails.
When the url is in the varaible sUrl:
ReplyDeletevar sFromUrl = sUrl.match(/from_url=[^&]*/)[0];
var sBasename = sFromUrl.match(/[^\/]*$/)[0];
Also see this example.
Use this to get your url variables in JS
ReplyDeletefunction getUrlVars()
{
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
and then string.substring(string.search("/")) to get your piece of string
