js 全屏方法

实际建议通过 高度 在resize 是判读 是否全屏 应该 f11 执行的全屏js 无法判断

// 全屏
var isFullScreen=false

function fullScreen(id) { //  el 是要放大的div的id
    let el = document.getElementById(id)||document.documentElement;
    let screen = el.requestFullScreen || el.webkitRequestFullScreen || el.mozRequestFullScreen || el.msRequestFullScreen
    let wscript = null
    if (typeof screen != "undefined" && screen) {
      screen.call(el);
      return;
    }
    if (typeof window.ActiveXObject != "undefined") {
      wscript = new ActiveXObject("WScript.Shell");
      if (wscript) {
        wscript.SendKeys("{F11}");
      }
    }
    isFullScreen=true
  }


// 退出全屏

function exitFullScreen() {
  let screen = document.cancelFullScreen || document.webkitCancelFullScreen || document.mozCancelFullScreen || document.exitFullScreen
  let wscript = null

  if (typeof screen != "undefined" && screen) {
    screen.call(document);
    return;
  }

  if (typeof window.ActiveXObject != "undefined") {
    wscript = new ActiveXObject("WScript.Shell");
    if (wscript != null) {
      wscript.SendKeys("{F11}");
    }
  }
  isFullScreen=false
}
