单击 3 次后执行 Javascript 函数的 HTML 链接

Question

我想知道是否有一种方法可以在用户单击链接 3 次时才执行 javascript 函数。这是 HTML 代码：<a onclick="toggleFullScreen()">Toggle Fullscreen</a>这是 Javascript 部分：function toggleFullScreen() {  if (!document.fullscreenElement &&    // alternative standard method      !document.mozFullScreenElement && !document.webkitFullscreenElement && !document.msFullscreenElement ) {  // current working methods    if (document.documentElement.requestFullscreen) {      document.documentElement.requestFullscreen();    } else if (document.documentElement.msRequestFullscreen) {      document.documentElement.msRequestFullscreen();    } else if (document.documentElement.mozRequestFullScreen) {      document.documentElement.mozRequestFullScreen();    } else if (document.documentElement.webkitRequestFullscreen) {      document.documentElement.webkitRequestFullscreen(Element.ALLOW_KEYBOARD_INPUT);    }  } else {    if (document.exitFullscreen) {      document.exitFullscreen();    } else if (document.msExitFullscreen) {      document.msExitFullscreen();    } else if (document.mozCancelFullScreen) {      document.mozCancelFullScreen();    } else if (document.webkitExitFullscreen) {      document.webkitExitFullscreen();    }  }}

对全局变量使用本地存储。看到这篇文章，它甚至有一个计算点击次数的例子：https : //www.w3schools.com/jsref/prop_win_localstorage.asp
