JavaScript代码（一）

1.将URL参数返回，并转化为对象的方法：

 1  function getUrlParams() {
 2         var url = location.search;
 3         var params = new Object();
 4         if (url.indexOf("?") != -1) {
 5           var str = url.substr(1);
 6           strs = str.split("&");
 7           for(var i = 0; i < strs.length; i ++) {
 8            params[strs[i].split("=")[0]]=strs[i].split("=")[1];
 9           }
10         }
11         return params;
12     };

2.将数值转换为1,0标志位

 1 function splitToArray(number){
 2     var targets=[];
 3     var remainder;
 4     var temp;
 5     for(i=number,j=1;number>=j;i=i-((i/j)%2)*j,j=j*2){        
 6         remainder=(i/j)%2;
 7         if(remainder==1){
 8             targets=targets.concat(j);
 9         }
10     }
11     return targets;
12 }

3.将1,0标志位转换为数值

1 function caculateByArray(targets){
2     var target=parseInt(0);
3     for(i=0;i<targets.length;i++){
4         target=target+parseInt(targets[i]);        
5     }
6     return target;
7 }
