JS And Css Dynamic includes

動態載入不知道在firefox & Ie 會有什麼不同呢？


var css;
function include_css(css_file) {
var html_doc = document.getElementsByTagName('head')[0];
css = document.createElement('link');
css.setAttribute('rel', 'stylesheet');
css.setAttribute('type', 'text/css');
css.setAttribute('href', css_file);
html_doc.appendChild(css);

// alert state change
css.onreadystatechange = function () {
if (css.readyState == 'complete') {
alert('CSS onreadystatechange fired');
}
}
css.onload = function () {
alert('CSS onload fired');
}
return false;
}

var js;
function include_js(file) {
var html_doc = document.getElementsByTagName('head')[0];
js = document.createElement('script');
js.setAttribute('type', 'text/javascript');
js.setAttribute('src', file);
html_doc.appendChild(js);

js.onreadystatechange = function () {
if (js.readyState == 'complete') {
alert('JS onreadystate fired');
}
}

js.onload = function () {
alert('JS onload fired');
}
return false;
}
