JS alert is not functioning in ColdFusion

Question

I am trying to figure out why this JS alert is not working. The function of the alert is to validate if the data been selected before.

 <script type="text/javascript">
        alert("This location been chosen.\n Please choose another location.");
        history.back();
 </script>

However when I try to check the error, I'm turning on the ColdFusion debug, the js alert runs smoothly.

Answer 1

Unless window.alert has been redefined it will work as long as you pass it a value that is a string (or converts to a string).

I'd suspect that either the script tag is not being output in your generated source or that there is a JavaScript error elsewhere that is causing all code after it to not parse.

Answer 2

很可能是您生成的JavaScript无效-在浏览器中检查JavaScript警告。
