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

asp.net:

   

    HtmlGenericControl myHtmlJS = new HtmlGenericControl("script");
    myHtmlJS.Attributes.Add("type","text/javascript");
    myHtmlJS.Attributes.Add("src","javascript/Kathy.js");
    Page.Header.Controls.Add(myHtmlJS);

    HtmlLink myLink = new HtmlLink();
    myLink.Attributes.Add("type","text/css");
    myLink.Attributes.Add("href","css/Common.css");
    myLink.Attributes.Add("rel","Stylesheet");

    Page.Header.Controls.Add(myLink);

Javascript:

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);            
}
