一天先後有兩個同事問我為啥他的js代碼出現了莫名其妙的問題
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /><title>Untitled Document</title><script src=‘js/jquery-1.3.2.min.js‘/><script>console.log(111111);//不會執行</script></head><body><iframe /></body></html><script>console.log(1111111111);//也不會執行</script>
上面兩處代碼都不會執行的原因，是因為script和iframe標籤都是不可以自關閉的。
還有就是<script type=‘javascript‘> type如果寫錯了，js也不會執行。
