在用到編輯器時(shí)，就會(huì)碰到一點(diǎn)，那就是標(biāo)簽的閉合問(wèn)題，這個(gè)問(wèn)題非常嚴(yán)峻，因?yàn)檫@可能會(huì)導(dǎo)致網(wǎng)頁(yè)顯示的整體樣式受到破壞。
這最近在PJ的function庫(kù)里看到的這個(gè)函數(shù)，感覺(jué)思路差了點(diǎn)，不過(guò)相對(duì)比較完美，只是閉合標(biāo)簽時(shí)的順序問(wèn)題，呵呵
修改一下數(shù)組arrTags里的各元素內(nèi)容，可以達(dá)到閉合任何標(biāo)簽的功能。
在此，我給增加了一些注釋，方便大家一起學(xué)習(xí)學(xué)習(xí)
復(fù)制代碼 代碼如下:
Function closeUBB(strContent)
'*************************************
'自動(dòng)閉合UBB
'*************************************
Dim arrTags, i, OpenPos, ClosePos, re, strMatchs, j, Match
Set re = New RegExp '申明re對(duì)象
re.IgnoreCase = True '設(shè)置是否區(qū)分字符大小寫
re.Global = True '設(shè)置全局可用性
arrTags = Array("code", "quote", "list", "color", "align", "font", "size", "b", "i", "u", "html") '建立數(shù)組，存儲(chǔ)相關(guān)需要檢測(cè)是否閉合的標(biāo)簽
For i = 0 To UBound(arrTags) '循環(huán)對(duì)數(shù)組里的每一個(gè)元素進(jìn)行檢測(cè)
OpenPos = 0 '初始化當(dāng)前標(biāo)簽開始標(biāo)記的個(gè)數(shù)
ClosePos = 0 '初始化當(dāng)前標(biāo)簽結(jié)束標(biāo)記的個(gè)數(shù)
re.Pattern = "\[" + arrTags(i) + "(=[^\[\]]+|)\]" '開始分別正則判斷開始與結(jié)束標(biāo)記的個(gè)數(shù)
Set strMatchs = re.Execute(strContent)
For Each Match in strMatchs
OpenPos = OpenPos + 1
Next
re.Pattern = "\[/" + arrTags(i) + "\]"
Set strMatchs = re.Execute(strContent)
For Each Match in strMatchs
ClosePos = ClosePos + 1
Next
For j = 1 To OpenPos - ClosePos '當(dāng)開始與結(jié)束標(biāo)記數(shù)量不一致時(shí)，閉合當(dāng)前標(biāo)簽
strContent = strContent + "[/" + arrTags(i) + "]"
Next
Next
closeUBB = strContent
Set re = Nothing
End Function

closehtml的注釋同上
復(fù)制代碼 代碼如下:
Function closehtml(strContent)
'*************************************
'自動(dòng)閉合html
'*************************************
Dim arrTags, i, OpenPos, ClosePos, re, strMatchs, j, Match
Set re = New RegExp
re.IgnoreCase = True
re.Global = True
arrTags = Array("p", "DIV", "span", "table", "ul", "font", "b", "u", "i", "h1", "h2", "h3", "h4", "h5", "h6")
For i = 0 To UBound(arrTags)
OpenPos = 0
ClosePos = 0
re.Pattern = "\<" + arrTags(i) + "( [^\<\>]+|)\>"
Set strMatchs = re.Execute(strContent)
For Each Match in strMatchs
OpenPos = OpenPos + 1
Next
re.Pattern = "\</" + arrTags(i) + "\>"
Set strMatchs = re.Execute(strContent)
For Each Match in strMatchs
ClosePos = ClosePos + 1
Next
For j = 1 To OpenPos - ClosePos
strContent = strContent + "</" + arrTags(i) + ">"
Next
Next
closehtml = strContent
Set re = Nothing
End Function
