js前端 技术--try-catch语句

在做前端权限管理的时候，循环方法的时候 发现有的会有异常，添加try-catch语句语句

 

try
                  {

                   for(var i =0;i                       for(var j =0;j                           /*if(res[i].children[j].children.size()>0){*/
                          if(typeof res[i].children[j].children != "undefined"){
         for(var x =0;x

            if("投资指令查询" == res[i].children[j].children[x].text){
               isHave = true;
               console.log(res[i].children[j].children[x].text);

            }
            if("待审批任务" == res[i].children[j].children[x].text){
               console.log(res[i].children[j].children[x].text);
               resultApproal = true;
            }
            if("已办事宜" == res[i].children[j].children[x].text){
               console.log(res[i].children[j].children[x].text);
               resultYb = true;
            }
         }
                          }
                      }
                  }
                  }catch (err){
   console.log(err);
}finally {
                      if(isHave == true){

                          var html = '

'
                              + ''
                              +''
                              +'

投资指令查询

';
                          $("#showRole").append(html);
                      }
}

              }

简单的移动端的权限管理

根绝业务处理可以 选择性的是否抛出异常
