JavaScript栏目隐藏简单实现
1.构建JavaScript库
(function(){ //将命名空间IC注册到windowwindow['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：
“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。
3.HTML文件代码
