如何找出第二次点击按钮 [英] how to find out second click on a button

问题描述

我创建了一个jquery函数，并通过链接对其进行了调用.

i make a jquery function and called it by linking.

<a href="javascript:myfunc(ID)"></a>

我想检查一下按钮是第二次单击还是第一次单击

and i want to check in my function that button is second time click or first time

我想在第一次和第二次click()上做出不同的事件

推荐答案

您可以使用 .toggle() ，像这样:

You can use .toggle(), like this:

$("#myButton").toggle(function() {
  //click first time 
}, function () {
  //click second time
});

您可以根据需要实际添加任意数量，它会循环浏览它们.如果您需要在第二次单击后轰炸，只需 .unbind() ，方法是在最终点击功能的底部添加一个$(this).unbind('click')，如下所示:

You can add as many as you want actually, it just cycles through them, If you need to bomb out after the second click, just .unbind() by adding a $(this).unbind('click') at the bottom of the last click function, like this:

$("#myButton").toggle(function() {
  //click first time 
}, function () {
  //click second time
  $(this).unbind('click'); //without this, it goes back to the first function
                           //on the next click
});
