jQuery 多个事件触发同一个函数 [英] jQuery multiple events to trigger the same function

问题描述

有没有办法让 keyup、keypress、blur 和 change 事件调用相同的函数一行还是我必须分开做?

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，并希望确保在任何情况下都不会错过验证，无论是键入还是粘贴到框中.

The problem I have is that I need to validate some data with a db lookup and would like to make sure validation is not missed in any case, whether it is typed or pasted into the box.

推荐答案

您可以使用 .on() 将一个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)
