1、动态加载JS文件。
var loadJs = function(d, a) {
var c = document.getElementsByTagName("head")[0] || document.head
|| document.documentElement;
var b = document.createElement("script");
b.setAttribute("type", "text/javascript");
b.setAttribute("charset", "UTF-8");
b.setAttribute("src", d);
if (typeof a === "function") {
if (window.attachEvent) {
b.onreadystatechange = function() {
var e = b.readyState;
if (e === "loaded" || e === "complete") {
b.onreadystatechange = null;
a()
}
}
} else {
b.onload = a
}
}
c.appendChild(b)
};
loadJs("http://changyan.sohu.com/upload/changyan.js", function() {
window.changyan.api.config({
appid : appid,
conf : conf
})
});
