js中将URL中的参数提取出来作为对象的实现代码

(function() { 
var urlToObject = function(url) { 
var urlObject = {}; 
if (/\?/.test(url)) { 
var urlString = url.substring(url.indexOf("?")+1); 
var urlArray = urlString.split("&"); 
for (var i=0, len=urlArray.length; i<len; i++) { 
var urlItem = urlArray[i]; 
var item = urlItem.split("="); 
urlObject[item[0]] = item[1]; 
} 
return urlObject; 
} 
}; 
var testUrl = "http://tools.3water.com/index.php?key0=0&key1=1&key2=2"; 
var result = urlToObject(testUrl); 
for (var key in result) { 
alert(key + "=" + result[key]); 
} 
})();
