'with' is not allowed in strict mode.解決方法!
阿新 • • 發佈:2018-11-24
今天在最新的MyEclipse中匯入了一個包含有jquery-1.6.2.js的專案。
結果編譯器報錯:'with' is not allowed in strict mode.
原因:由於js在嚴格模式下不允許使用with關鍵字!
分析:with語句的作用是將程式碼的作用域設定到一個特定的作用域中
比如:
如果不使用with關鍵字程式碼要寫成這樣:var qs = location.search.substring(1); var hostName = location.hostname; var url = location.href;
如果使用with關鍵字可以這樣寫:
with (location){ var qs = search.substring(1); var hostName = hostname; var url = href; }
解決方案:
找到關鍵所在!那麼只需要把with關鍵字對應的程式碼塊中省略的關鍵字新增上,並把with刪掉 儲存就好了!!
當然這是我遇到的情況。。。。謹供大家參考!!!!!
我的情況:
