jQuery的：form.submit（FN）不与Asp.net工作？ [英] jQuery: form.submit(fn) does not work with Asp.net?

问题描述

我试图附加一个事件处理程序form.submit上没有成功asp.net页面呈现。我想每一个拦截回传，以及文档。说，我应该可以。难道我做错了什么？

  $（文件）。就绪（函数（）{
    $（形式）。递交（函数（）{
            警报（'形式服从'）;
            调试器;
    }）;
}）;
 

解决方案

不知道，如果你还在寻找，但这里是解决方案，我有。我不认为它与事件，如果使用，也就是说，stopPropagation（），但它会让你提交表单之前运行一些脚本取消。

 ＆LT;脚本类型=文/ JavaScript的＆GT;
    $（函数（）{
        VAR oldSubmit = __doPostBack;
        VAR的newsubmit =功能（的eventTarget，eventArgument）{
            警报（'自定义提交功能'）;
            返回oldSubmit（的eventTarget，eventArgument）;
        };
        __doPostBack =的newsubmit;
    }）;
＆LT; / SCRIPT＆GT;
 

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;
    });
});

解决方案

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>
