jq的getScript函数不支持chaset?override掉!

其实我从来不用jq或者其他框架的,这两天偶然在一个小项目里面发现jq的一个小bug:getScript函数没有透传charset信息,如果试图在页面上加载一个跨编码的脚本的时候会导致编码错误。写了一个补丁函数覆盖掉原来的:

$.getScript=function(url, callback , charset){
    $.ajax({
        url: url,
        dataType: "script",
        success:callback,
        scriptCharset:charset
    })
}    

这几年代码写得很少,轻喷。这里是demo代码 ,同时也到jq的github上提交了一个issue

<!DOCTYPE html>

<HEAD>

<script src="http://cdn.jsdelivr.net/jquery/1.11.1/jquery.js"></script>

    log(
