例1 重新加载js文件
function loadJs(file) {
var head = $("head").remove("script[role='reload']");
$("<scri" + "pt>" + "</scr" + "ipt>").attr({ role: 'reload', src: file, type: 'text/javascript' }).appendTo(head);
}
例2 重新载入javascript文件的方法(给js定个id),自己封装成一个方法方便大家使用：
function reloadAbleJSFn(id,newJS)
{
var oldjs = null;
var t = null;
var oldjs = document.getElementById(id);
if(oldjs) oldjs.parentNode.removeChild(oldjs);
var scriptObj = document.createElement("script");
scriptObj.src = newJS;
scriptObj.type = "text/javascript";
scriptObj.id = id;
document.getElementsByTagName("head")[0].appendChild(scriptObj);
}
例3 jquery的就直接使用getScript就可以了。
