Question

我有一些由其他人编写的代码，如果邮政编码格式不正确并且停止提交页面，则应该打开弹出窗口。它在IE和Chrome中正常工作。但在Firefox中我得到弹出窗口，单击确定，然后页面提交。有人可以查看代码，让我知道错误做了什么？代码粘贴在此消息的末尾。

谢谢

可能就像选择器错误一样简单：

尝试更改此内容：

 $('#<%= btnAdd.ClientID %>').click(function (event) {
        if (beginZipValidation()) {
            //event.preventDefault();

            return;
        }
    });

反而有点像：

var myButtonId = "<%= btnAdd.ClientID %>"; // Now you know what this evaluates to client-side
var btnSelector = "#" + myButtonId;
$(btnSelector).click(function (event) {
        if (beginZipValidation()) {
            //event.preventDefault();

            return;
        }
    });

您是否正在使用Firebug或Chrome Developer工具等标准工具进行调试？如果是这样，请在那里抛出几个console.log("myButtonId: " + myButtonId);语句！

js / jquery - event.preventdefault似乎在firefox中不起作用
