針對(duì)自己項(xiàng)目中遇到的一些提示，做一些舉例說明：

1 [W099]：Mixed spaces and tabs

這個(gè)錯(cuò)誤是最常見的，意思是在同一行中，空格和Tab縮進(jìn)混合使用了，修改很簡(jiǎn)單，一般是刪除Tab縮進(jìn)，全部改為空格。為了方便，我們可以把編輯器的Tab縮進(jìn)設(shè)置成2個(gè)或4個(gè)空格，來(lái)代替原有的縮進(jìn)。

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

這個(gè)錯(cuò)誤提示的很詭異，我是用如下代碼提示的這個(gè)錯(cuò)誤 index-1 <0 ? index = 0:index = index - 1;??這是一個(gè)逗號(hào)表達(dá)式，但是JSLInt認(rèn)為這里不應(yīng)該用表達(dá)式，而必須是一個(gè)函數(shù)，所以，如果非常在乎這個(gè)錯(cuò)誤，就改為if else 語(yǔ)句吧

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

這個(gè)錯(cuò)誤是說，我們要是用全等來(lái)代替等于，如果表達(dá)式兩邊的數(shù)據(jù)類型是一致的話，建議使用全等來(lái)判斷

4 [W033]：Missing semicolon

缺少分號(hào)；這個(gè)一般都是自己忘記寫了吧，但是有一個(gè)需要注意的是，對(duì)于只有一句的結(jié)構(gòu)，后面也需要寫分號(hào)。例如：if(index<0) {index=tcount-1} 這句代碼，正確寫法是if(index<0) {index=tcount-1;}，我是經(jīng)常忘記這里寫分號(hào)，汗...

其他還有一些錯(cuò)誤提示就對(duì)照一下改吧，要培養(yǎng)自己良好的代碼風(fēng)格和書寫習(xí)慣。
