我想在单击一个元素时运行两个不同的功能。如果我第一次单击按钮，clickfunction1 应该运行，而当我第二次单击按钮时，clickfunction2 应该运行。我的问题是，当我交替单击一个元素时，两个不同的函数应该一个接一个地运行，就像第一次单击时第一个函数将运行，第二次单击相同的元素时第二个函数将运行。

最佳答案
在此解决方案中，我创建了一个没有编号的新函数 clickFunction() 来管理您的两个现有函数，并且我还声明了一个可切换的 bool 标志...
var Toggle=false;
function clickFunction(Toggle2){
if(Toggle2){clickFunction1();} else {clickFunction2();}
Toggle=!Toggle;
}
基本的 HTML...
<button onclick="clickFunction(Toggle);"></button>
关于javascript - 两次点击同一元素可实现多种功能，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/59386724/
