如何:

<asp:Button ID="button" UseSubmitBehavior="false"/>

简单地添加这个属性到你的FORM标签:

onsubmit="return gbCanSubmit;"

然后，在你的SCRIPT标签中，添加这个:

var gbCanSubmit = false;

然后，当你创建一个按钮或出于任何其他原因(比如在函数中)你最终允许提交时，只需翻转全局布尔值并执行.submit()调用，类似于下面的示例:

function submitClick(){

  // error handler code goes here and return false if bad data

  // okay, proceed...
  gbCanSubmit = true;
  $('#myform').submit(); // jQuery example

}

我花了一些时间制作这款跨浏览器，适用于IE8、9、10、Opera 9+、Firefox 23、Safari(PC)和Safari(MAC)

示例:http://jsfiddle.net/greatbigmassive/ZyeHe/

基本代码-通过“onkeypress”附加到您的窗体和传递窗口调用此函数。事件”。

function stopEnterSubmitting(e) {
    if (e.keyCode == 13) {
        var src = e.srcElement || e.target;
        if (src.tagName.toLowerCase() != "textarea") {
            if (e.preventDefault) {
                e.preventDefault();
            } else {
                e.returnValue = false;
            }
        }
    }
}

//Turn off submit on "Enter" key

$("form").bind("keypress", function (e) {
    if (e.keyCode == 13) {
        $("#btnSearch").attr('value');
        //add more buttons here
        return false;
    }
});

只需从onsubmit处理程序返回false

<form onsubmit="return false;">

或者如果你想要一个中间的处理程序

<script>
var submitHandler = function() {
  // do stuff
  return false;
}
</script>
<form onsubmit="return submitHandler()">

I Have come across this myself because I have multiple submit buttons with different 'name' values, so that when submitted they do different things on the same php file. The enter / return button breaks this as those values aren't submitted. So I was thinking, does the enter / return button activate the first submit button in the form? That way you could have a 'vanilla' submit button that is either hidden or has a 'name' value that returns the executing php file back to the page with the form in it. Or else a default (hidden) 'name' value that the keypress activates, and the submit buttons overwrite with their own 'name' values. Just a thought.
