将这个标签添加到你的表单- onsubmit="return false;" 然后只能使用JavaScript函数提交表单。

这个链接提供了一个在Chrome、FF和IE9以及IE7和ie8的模拟器(IE9的开发者工具(F12)中为我工作过的解决方案。

http://webcheatsheet.com/javascript/disable_enter_key.php

//Turn off submit on "Enter" key

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

另一种方法是仅在表单应该提交时才将提交输入按钮附加到表单，并在表单填充期间将其替换为简单的div

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.

stopSubmitOnEnter (e) {
  var eve = e || window.event;
  var keycode = eve.keyCode || eve.which || eve.charCode;

  if (keycode == 13) {
    eve.cancelBubble = true;
    eve.returnValue = false;

    if (eve.stopPropagation) {   
      eve.stopPropagation();
      eve.preventDefault();
    }

    return false;
  }
}

然后在表格上:

<form id="foo" onkeypress="stopSubmitOnEnter(e);">

不过，如果不使用突兀的JavaScript会更好。
