jquery及js實現動態載入js檔案的方法，jqueryjs
本文執行個體講述了jquery及js實現動態載入js檔案的方法。分享給大家供大家參考，具體如下：
問題：
如果用jquery append直接載入script標籤的話，會報錯的。除了document.write外，還有沒有其他的比較好的動態載入js檔案的方法。
解決方案：
1、jquery方法
$.getScript("./test.js"); //載入js檔案$.getScript("./test.js",function(){ //載入test.js,成功後，並執行回呼函數 console.log("載入js檔案");});
2、js方法
<html><body></body></html><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 () { //載入,並執行回呼函數 alert($(window).height());});//loadScript("jquery-latest.js"); //載入js檔案</script>
