jQuery多个事件触发相同的功能 [英] jQuery multiple events to trigger the same function

问题描述

有没有办法使用 keyup ，按键，模糊和更改在一行或者我必须单独做它们？

Is there a way to have keyup, keypress, blur, and change events call the same function in one line or do I have to do them separately?

我遇到的问题是我需要使用数据库查找来验证一些数据，并希望确保没有办法验证是错过天气输入或粘贴到框中。

The problem I have is that I need to validate some data with a db lookup and would like to make sure that there is no way that the validation is missed weather it is typed or pasted into the box.

推荐答案

您可以使用 .on（）将函数绑定到多个事件：

You can use .on() to bind a function to multiple events:

$('#element').on('keyup keypress blur change', function(e) {
    // e.type is the type of event fired
});

或者只是将函数作为参数传递给普通事件函数：

Or just pass the function as the parameter to normal event functions:

var myFunction = function() {
   ...
}

$('#element')
    .keyup(myFunction)
    .keypress(myFunction)
    .blur(myFunction)
    .change(myFunction)
