This time I will bring you a detailed explanation of the steps to load and remove js and css files. What are the precautions and the following are practical cases. Let’s take a look at them together.
<script language="JavaScript"> //动态加载一个js/css文件 function loadjscssfile(filename, filetype){ if (filetype=="js"){ varfileref=document.createElement('script') fileref.setAttribute("type","text/javascript") fileref.setAttribute("src",filename) } else if (filetype=="css"){ varfileref=document.createElement("link") fileref.setAttribute("rel","stylesheet") fileref.setAttribute("type","text/css") fileref.setAttribute("href",filename) } if (typeof fileref!="undefined") document.getElementsByTagName("head")[0].appendChild(fileref) } </script>
loadjscssfile("myscript.js","js") loadjscssfile("javascript.PHP","js") loadjscssfile("mystyle.css","css") <scriptlanguage="javascript"> //移动已经加载过的js/css function removejscssfile(filename,filetype){ vartargetelement=(filetype=="js")? "script" :(filetype=="css")? "link" : "none" var targetattr=(filetype=="js")?"src" : (filetype=="css")? "href" :"none" varallsuspects=document.getElementsByTagName(targetelement) for (var i=allsuspects.length; i>=0;i--){ if (allsuspects[i] &&allsuspects[i].getAttribute(targetattr)!=null && allsuspects[i].getAttribute(targetattr).indexOf(filename)!=-1) allsuspects[i].parentNode.removeChild(allsuspects[i]) } } </script>
