針對自己項目中遇到的一些提示，做一些舉例說明：

1 [W099]：Mixed spaces and tabs

這個錯誤是最常見的，意思是在同一行中，空格和Tab縮進混合使用了，修改很簡單，一般是删除Tab縮進，全部改為空格。為了友善，我們可以把編輯器的Tab縮進設定成2個或4個空格，來代替原有的縮進。

2 [W030]：Expected an assignment or function call and instead saw an expression

這個錯誤提示的很詭異，我是用如下代碼提示的這個錯誤 index-1 <0 ? index = 0:index = index - 1;  這是一個逗号表達式，但是JSLInt認為這裡不應該用表達式，而必須是一個函數，是以，如果非常在乎這個錯誤，就改為if else 語句吧

3 [W041]：Use '===' to compare with ...

這個錯誤是說，我們要是用全等來代替等于，如果表達式兩邊的資料類型是一緻的話，建議使用全等來判斷

4 [W033]：Missing semicolon

缺少分号；這個一般都是自己忘記寫了吧，但是有一個需要注意的是，對于隻有一句的結構，後面也需要寫分号。例如：if(index<0) {index=tcount-1} 這句代碼，正确寫法是if(index<0) {index=tcount-1;}，我是經常忘記這裡寫分号，汗...

其他還有一些錯誤提示就對照一下改吧，要培養自己良好的代碼風格和書寫習慣。
