如何将一键式事件处理程序用于多个按钮 [英] How to use one click event handler for multiple buttons

问题描述

我有4个具有不同ID的按钮.当我单击它们时，我需要执行一项功能.所以我需要这样的东西:

I have 4 buttons with different id's. When i click on them i need to perform one function. So i need something like this:

$('#button #button').click(function()

推荐答案

要一次性选择4个按钮，请输入以下内容:

To select the 4 buttons at once you write the following:

$('#button1, #button2, #button3, #button4').click(function(event){ /* code here */ });

如果您需要确定按下了哪个按钮，请输入以下内容:

If you need to identify which button was pressed, write something like:

$('#button1, #button2, #button3, #button4').click(function(event){ 
    if($(event.target).attr('id')=='button1'){
        /* specific code for button1 */
    } else if($(event.target).attr('id')=='button2'){
        /* specific code for button2 */
    } else if($(event.target).attr('id')=='button3'){
        /* specific code for button3 */
    } else if($(event.target).attr('id')=='button4'){
        /* specific code for button4 */
    } 
});
