2、动态加载JS文件
<script type="text/javascript">function loadScript(url, callback) {var script = document.createElement("script");script.type = "text/javascript";if(typeof(callback) != "undefined"){if (script.readyState) {script.onreadystatechange = function () {if (script.readyState == "loaded" || script.readyState == "complete") {script.onreadystatechange = null;callback();}};} else {script.onload = function () {callback();};}}script.src = url;document.body.appendChild(script);}loadScript("jquery-latest.js", function () { //加载,并执行回调函数alert($(window).height());});//loadScript("jquery-latest.js"); //加载js文件</script>
