问题描述

我试图在asp.net 呈现的页面上将事件处理程序附加到form.submit，但没有成功.我想拦截每个回发和文档.说我应该可以.我做错了什么吗?

I am trying to attach an event handler to form.submit on asp.net rendered pages with no success. I want to intercept every postback, and doc. says that I should be able. Am I doing something wrong?

$(document).ready(function() {
    $("form").submit(function() {
            alert('Form submit');
            debugger;
    });
});

推荐答案

不知道您是否还在寻找它，但这是我的解决方案.如果使用例如 stopPropagation()，我认为它不适用于事件取消，但它可以让您在提交表单之前运行一些脚本.

Don't know if you are still looking for it, but here is the solution I have. I don't think it works with event canceling if using, say, stopPropagation() but it will let you run some script before submitting the form.

<script type="text/javascript">
    $(function () {
        var oldSubmit = __doPostBack;
        var newSubmit = function (eventTarget, eventArgument) {
            alert('custom submit function');
            return oldSubmit(eventTarget, eventArgument);
        };
        __doPostBack = newSubmit;
    });
</script>
