你也可以使用javascript:void(0)来阻止表单提交。

<form action="javascript:void(0)" method="post">
    <label for="">Search</label>
    <input type="text">
    <button type="sybmit">Submit</button>
</form>

<form action="javascript:void(0)" method="post"> <标签= " " > < / >标签搜索 < input type = " text " > <按钮类型=“sybmit”> > < /按钮提交 > < /形式

我有一个类似的问题，我有一个网格与“ajax textfields”(Yii CGridView)，只有一个提交按钮。每次我在文本框中搜索并点击输入提交的表单。我必须对按钮做一些事情，因为它是视图之间唯一的公共按钮(MVC模式)。我所要做的就是删除type="submit"，并把onclick="document.forms[0].submit()

第4.10.22.2节隐式提交的W3C HTML5规范说:

A form element's default button is the first submit button in tree order whose form owner is that form element. If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button. Note: Consequently, if the default button is disabled, the form is not submitted when such an implicit submission mechanism is used. (A button has no activation behavior when disabled.)

因此，一种符合标准的禁用表单隐式提交的方法是将禁用的提交按钮作为表单中的第一个提交按钮:

<form action="...">
  <!-- Prevent implicit submission of the form -->
  <button type="submit" disabled style="display: none" aria-hidden="true"></button>

  <!-- ... -->

  <button type="submit">Submit</button>
</form>

这种方法的一个很好的特性是它不需要JavaScript;无论是否启用JavaScript，都需要一个符合标准的web浏览器来防止隐式表单提交。

在我对其他解决方案感到沮丧之后，这在所有浏览器中都有效。name_space外层函数只是为了避免声明全局变量，这也是我推荐的。

$(function() {window.name_space = new name_space();}); //jquery doc ready
function name_space() {
    this.is_ie = (navigator.userAgent.indexOf("MSIE") !== -1);

    this.stifle = function(event) {
        event.cancelBubble;
        event.returnValue = false;
        if(this.is_ie === false) {
            event.preventDefault();
        }
        return false;
    }

    this.on_enter = function(func) {
        function catch_key(e) {
            var enter = 13;
            if(!e) {
                var e = event;
            }
            keynum = GetKeyNum(e);
            if (keynum === enter) {
                if(func !== undefined && func !== null) {
                    func();
                }
                return name_space.stifle(e);
            }
            return true; // submit
        }

        if (window.Event) {
            window.captureEvents(Event.KEYDOWN);
            window.onkeydown = catch_key;
        }
        else {
            document.onkeydown = catch_key;
        }

        if(name_space.is_ie === false) {
            document.onkeypress = catch_key;    
        }
    }
}

示例使用:

$(function() {
    name_space.on_enter(
        function () {alert('hola!');}
    );
});

如果使用Vue，使用以下代码来阻止用户通过按Enter提交表单:

<form @submit.prevent>...</form>

这是我达到目标的解决方案， 它干净有效。

$('form').submit(function () {
  if ($(document.activeElement).attr('type') == 'submit')
     return true;
  else return false;
});
