JavaScript控制栏目的显示和隐藏代码

1.构建JavaScript库

(function(){
		  
	//将命名空间IC注册到window
	window['JSHide']={};  
	
	//隐藏侧边栏，并将图片换成右箭头图片
	function yc()
	{	
		document.getElementById("cloone").style.display ="none";
		document.getElementById("img").innerHTML ="<img src='Image/右箭头.png' width='10' height='10' longdesc='Image/右箭头.png' onclick='JSHide.xs()' />";
		
	}
	window['JSHide']['yc']=yc;
	
	//显示侧边栏，并将图片换成左箭头
	function xs()
	{
		document.getElementById("cloone").style.display ="";
        document.getElementById("img").innerHTML ="<img src='Image/左箭头.png' width='10' height='10' longdesc='Image/左箭头.png' onclick='JSHide.yc()' />";
		
	}
	window['JSHide']['xs']=xs;
})();

2.将JS文件插入到HTML文件中：

&nbsp&nbsp&nbsp“插入”–“HTML”–“脚本对象”—“脚本”，选择好脚本文件后将其插入到HTML文件中。
