这对我很管用。 onkeydown = "返回! (event.keyCode = = 13)”

    <form id="form1" runat="server" onkeydown="return !(event.keyCode==13)">

   </form>

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.

放入javascript外部文件

   (function ($) {
 $(window).keydown(function (event) {  

    if (event.keyCode == 13) {

        return false;
    }
});

 })(jQuery);

或者在body tag里面

<script>


$(document).ready(function() {
    $(window).keydown(function(event) {
        alert(1);

        if(event.keyCode == 13) {

            return false;
        }
    });
});

</script>

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

}

我也遇到了同样的问题(表单包含大量的文本字段和不熟练的用户)。

我是这样解决的:

function chkSubmit() {
    if (window.confirm('Do you want to store the data?')) {
        return true;
    } else {
        // some code to focus on a specific field
        return false;
    }
}

在HTML代码中使用这个:

<form
    action="go.php" 
    method="post"
    accept-charset="utf-8"  
    enctype="multipart/form-data"
    onsubmit="return chkSubmit()"
>

通过这种方式，ENTER键按计划工作，但需要确认(通常是第二次按ENTER键)。

我留给读者的任务是，如果用户决定继续使用表单，那么脚本会将用户发送到按ENTER的字段中。

在我的案例中，这个jQuery JavaScript解决了这个问题

jQuery(function() {
            jQuery("form.myform").submit(function(event) {
               event.preventDefault();
               return false;
            });
}
