页面中js加载完全的方法
|
function loadScript（ url, callback） { var script = document.createElement("script"); script.type = "text/javascript"; 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.getElementsByName("head")[0].appendChild(script); } |
如何让脚本的执行顺序按照你设定的顺序执行，使用嵌套的方式：
|
loadScript("file1.js", function() { loadScript("file2.js", function() { loadScript("file3.js", function() { alert("All files are loaded"); }); }); }); |
