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
