其實我從來不用jq或者其他框架的，這兩天偶然在一個小項目里面發(fā)現(xiàn)jq的一個小bug：getScript函數(shù)沒有透傳charset信息，如果試圖在頁面上加載一個跨編碼的腳本的時候會導(dǎo)致編碼錯誤。寫了一個補丁函數(shù)覆蓋掉原來的：
$.getScript=function(url, callback , charset){
$.ajax({
url: url,
dataType: "script",
success:callback,
scriptCharset:charset
})
}
這幾年代碼寫得很少，輕噴。這里是
demo代碼 ，同時也到j(luò)q的github上提交了
