JS通用方法总结（一）

 1 /**
 2  * id数组转换为json字符串
 3  */
 4 function arrayTojson(arr) {
 5     var jsonIds = "[";
 6     for ( var i = 0; i < arr.length; i++) {
 7         if (i == arr.length - 1) {
 8             jsonIds += arr[i].eventid;
 9         } else {
10             jsonIds += arr[i].eventid + ",";
11         }
12     }
13     return jsonIds += "]";
14 }

 1 /**
 2  * 获取系统的url
 3  * @returns fullUrl：系统访问路径，例如：http://localhost:8080/amudraya/amudraya
 4  */
 5 function getURL(){
 6     var fullUrl = window.location.href;
 7     var a=fullUrl.lastIndexOf(‘/‘);
 8     fullUrl=fullUrl.substring(0,a);
 9     var b=fullUrl.lastIndexOf(‘/‘);
10     fullUrl=fullUrl.substring(0,b);
11     var c=fullUrl.lastIndexOf(‘/‘);
12     fullUrl=fullUrl.substring(0,c);
13     return fullUrl;
14 }
