禁用alert（）; [英] Disable alert();

问题描述

我无法控制的页面上生成的代码包含警报。有没有jQuery或其他方法来禁用alert（）工作？

Code that is generated on my page that I cannot control contains an alert. Is there a jQuery or other way to disable alert() from working?

我想要禁用/修改的javascript是：

The javascript that is being generated that I want to disable/modify is:

function fndropdownurl(val)
1317 { var target_url
1318 target_url = document.getElementById(val).value;
1319 if (target_url == 0)
1320 {
1321 alert("Please Select from DropDown")
1322 }
1323 else
1324 {
1325 window.open(target_url);
1326 return;
1327 }
1328 } 

我想在第1321行禁用警报

I want to disable the alert on line 1321

谢谢

推荐答案

只需覆盖提醒使用您自己的空函数。

Simply overwrite alert with your own, empty, function.

window.alert = function() {};

// or simply
alert = function() {};
