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>
