想让HTML表单提交什么都不做 [英] Want html form submit to do nothing

问题描述

我要被提交后，HTML表单什么也不做。

I want an html form to do nothing after it has been submitted.

action="" 

也是白搭，因为它会导致页面重新加载。

is no good because it causes the page to reload.

基本上我想只要一个按钮为pressed或有人打进入输入一次数据之后一个ajax函数被调用。是的，我可以在表单标签，并添加只是调用从按钮的onclick事件的功能，但我也希望没有得到所有的hackish的按下回车键功能。

Basically i want an ajax function to be called whenever a button is pressed or someone hits "enter" after typing it data. Yes i could drop the form tag and add just call the function from the button's onclick event, but i also want the "hitting enter" functionality without getting all hackish.

推荐答案

通过使用返回false; 在您提交按钮调用JavaScript，你可以停止从提交表单。

By using return false; in the javascript that you call from the submit button, you can stop the form from submitting.

基本上，你需要下面的HTML：

Basically, you need the following HTML:

<form onsubmit="myFunction(); return false;">
<input type="submit" value="Submit">
</form>

那么JavaScript支持：

Then the supporting javascript:

<script language="javascript"><!--
function myFunction() {
    //do stuff
}
//--></script>

如果你希望，也可以具备一定的条件允许脚本来提交表单：

If you desire, you can also have certain conditions allow the script to submit the form:

<form onSubmit="return myFunction();">
<input type="submit" value="Submit">
</form>

搭配：

<script language="JavaScript"><!--
function myFunction() {
    //do stuff
    if (condition)
        return true;

    return false;    
}
//--></script>
