<head>
<linktype="text/css"rel="stylesheet"href="style/style.css"/>
<scripttype="text/javascript"src="js/jsFile.js"></script>
</head>
We commonly load external javascript (*.js) or css (*.css) file on the page with the aboveway,doesn't we? Actually, we can make use of javascript and DOM implementing dynamically loading those files.We can use operating DOM method to achieve it.For example, load an external javascript file and an external css file with the following function.
functionrequireFile(fileName,fileType)...{
varref;
if(fileType=="js")...{
ref=document.createElement("script");
ref.setAttribute("type","text/javascript");
ref.setAttribute("src",fileName);
}
if(fileType=="css")...{
ref=document.createElement("link");
ref.setAttribute("type","text/css");
ref.setAttribute("rel","stylesheet");
ref.setAttribute("href",fileName);
}
document.getElementsByTagName("head")[0].appendChild(ref);
}
Then. we can use requireFile("js/js.js", "js") to dynamically load js/js.js file or requireFile("style/style.css", "css") to dynamically load style.css file.
That's OK!
