js中将URL中的参数提取出来作为对象的实现代码

复制代码 代码如下:
(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.jb51.net/index.php?key0=0&key1=1&key2=2";
var result = urlToObject(testUrl);
for (var key in result) {
alert(key + "=" + result[key]);
}
})();
