js点击某一个链接交替执行两个函数(js实现网页全屏问题)

想实现的需求:
1、网页上有个“全屏显示”按钮(链接),点击全屏后执行函数fullScreen(),然后“显示全屏”二字变成“退出全屏”;
2、点击“退出全屏”执行函数exitFullScreen(),然后“退出全屏”变为“全屏显示”

function fullScreen() {
var el = document.documentElement;
var rfs = el.requestFullScreen || el.webkitRequestFullScreen ||
el.mozRequestFullScreen || el.msRequestFullScreen;
if(typeof rfs != "undefined" && rfs) {
rfs.call(el);
} else if(typeof window.ActiveXObject != "undefined") {
//for IE,这里其实就是模拟了按下键盘的F11,使浏览器全屏
var wscript = new ActiveXObject("WScript.Shell");
if(wscript != null) {
wscript.SendKeys("{F11}");
}
}
}
function exitFullScreen() {
var el = document;
var cfs = el.cancelFullScreen || el.webkitCancelFullScreen ||
el.mozCancelFullScreen || el.exitFullScreen;
if(typeof cfs != "undefined" && cfs) {
cfs.call(el);
} else if(typeof window.ActiveXObject != "undefined") {
//for IE,这里和fullScreen相同,模拟按下F11键退出全屏
var wscript = new ActiveXObject("WScript.Shell");
if(wscript != null) {
wscript.SendKeys("{F11}");
}
}
}
