CustomValidator 的 ClientValidationFunction 在设置 args.IsValid true/false 时失败

我有一个带有 ClientValidationFunction 的 CustomValidator，如下所示，

function checkAmount(source, args) {
        var opt = document.getElementById('<%=optByAmount.ClientID %>');
        var txt = document.getElementById('<%=txtAmount.ClientID %>');
        if (opt.checked == true && txt.value == '') {
            //args.IsValid = false;
            alert('failed');
        }
        else {
            //args.IsValid = true;
            alert('passed');
        }
    }

仅当注释行被注释时，我才会收到错误消息“通过”和“失败”。当这些线路启用时，我根本没有收到任何警报。为什么？？

编辑停止并运行代码 20 分钟（执行这部分代码之外的其他操作）后，它现在可以运行了！谢谢达米安和 ub1k。我永远不会知道为什么会发生:(

I have a CustomValidator with ClientValidationFunction as below

function checkAmount(source, args) {
        var opt = document.getElementById('<%=optByAmount.ClientID %>');
        var txt = document.getElementById('<%=txtAmount.ClientID %>');
        if (opt.checked == true && txt.value == '') {
            //args.IsValid = false;
            alert('failed');
        }
        else {
            //args.IsValid = true;
            alert('passed');
        }
    }

I receive error messages 'passed' and 'failed' ONLY when the commented lines are COMMENTED. When these lines are enabled, i don't get any alert at all. Why ??

EDIT
After stopping and running the code for 20 minutes (doing something other than this part of the code), It is working now !!! Thanks Damian and ub1k. I would never know why was it happening :(

您能否在代码中添加额外的行？

alert(args);

在第一行？

我已经仔细检查了你的代码，它非常适合我。除此之外，我多次使用 CustomValidator，问题可能出在其他地方。现在，如果您可以检查 args 是否存在，那将会很有帮助。

Could you please add additional line to your code?

alert(args);

in the first line?

I have double checked your code and it works perfectly for me. Apart from that I used CustomValidator many times and the problem is probably somewhere else. For now if you could check whether args exist it would be helpful.
