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