动态加载CSS和Javascript文件 javascript 和asp.net.

asp.net:

代码function LoadJSFile(form_control_block, fileURL)
{
var head = document.getElementsByTagName("head")[0];
var djs_block = "djs_"+form_control_block;
var k_scrpt = document.getElementById(djs_block);
if(k_scrpt != null){
head.removeChild(k_scrpt);
}
k_scrpt = document.createElement("script");
k_scrpt.id = djs_block;
k_scrpt.language = "javascript";
k_scrpt.type = 'text/javascript';
k_scrpt.defer = true;
k_scrpt.src = fileURL;
head.appendChild(k_scrpt);
}

function LoadCSSFile(form_control_block, fileURL)
{
var head = document.getElementsByTagName("head")[0];
var dcss_block = "dcss_"+form_control_block;
var k_dcss = document.getElementById(dcss_block);
if(k_dcss != null){
head.removeChild(k_dcss);
}
k_dcss = document.createElement("link");
k_dcss.id = dcss_block;
k_dcss.rel = "stylesheet";
k_dcss.type = 'text/css';
k_dcss.href = fileURL;
head.appendChild(k_dcss);
}
