javascript - Jquery 1.5.2 替代 .on() 函数

Question

有 Jquery 专家可以帮助我吗？

我在一个需要使用 Jquery 1.5.2 的项目中，并且需要使用 .on() 函数。

有什么方法可以让它发挥作用？

代码模型如下:

$(document).on('mozfullscreenchange webkitfullscreenchange fullscreenchange',function(){
     		 //some code
              alert("fulscreen change")
		 });

function fullscreen() {
          alert("full");
     		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();
			    }
		  	}
	   }

<button onclick='fullscreen()'>fullscreen</button>

您可以使用live() 旧版本

As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live(). ( Taken from http://api.jquery.com/live/ )

$('button').live('click', function() {
  alert('clicked');
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>

<button>click</button>
