字符串函数

var loc_url = window.location + ""; //读取网址
document.write(loc_url);
document.write("<br />")
var wh = loc_url.indexOf("?"); //根据字符定位
document.write(wh);
document.write("<br />")
var str = loc_url.substring(wh+1,loc_url.length); //找出字符串
document.write(str);
document.write("<br />")
var arr1 = str.split("&");
for(var x in arr1){
document.write(arr1[x]);
document.write("<br />"); //划分成子串，做成数组
}
var arr=[];
for(var x in arr1){
var temp_arr = arr1[x].split("=");
arr[temp_arr[0]]=temp_arr[1];
}
for(var x in arr){
document.write(x + " => " + arr[x] + ",");
}
