我如何实现< input type =“文本">的onchange操作.用jQuery? [英] How do I implement onchange of <input type="text"> with jQuery?

问题描述

<select>具有此API.那<input>呢?

<select> has this API. What about <input>?

推荐答案

您可以使用 .change()

You can use .change()

$('input[name=myInput]').change(function() { ... });

但是，此事件仅在选择器失去焦点时才会触发，因此您需要单击其他位置才能进行此工作.

However, this event will only fire when the selector has lost focus, so you will need to click somewhere else to have this work.

如果这不太适合您，则可以使用其他一些 jQuery事件，例如关键字，键按下-取决于您想要的确切效果.

If that's not quite right for you, you could use some of the other jQuery events like keyup, keydown or keypress - depending on the exact effect you want.
