HTML編碼轉(zhuǎn)換、HTML部分實(shí)體

網(wǎng)頁(yè)中的字符編碼:

1、編碼轉(zhuǎn)換(to Unicode)

(程序代碼來(lái)源于網(wǎng)絡(luò))

 

Js版

<script>
test = "你好abc"
str = ""
for( i=0;   i<test.length; i++ )
{
temp = test.charCodeAt(i).toString(16);
str   += "\\u"+ new Array(5-String(temp).length).join("0") +temp;
}
document.write (str)
</script>


vbs版

Function Unicode(str1)
Dim str,temp
str = ""
For i=1   to len(str1)
temp = Hex(AscW(Mid(str1,i,1)))
If len(temp) < 5 Then   temp = right("0000" & temp, 4)
str = str & "\u" & temp
Next
Unicode = str
End Function


Function htmlentities(str)
For i = 1 to Len(str)
char = mid(str, i, 1)
If Ascw(char) > 128 then
htmlentities = htmlentities & "&#" & Ascw(char) & ";"
Else
htmlentities = htmlentities & char
End if
Next
End Function

 

coldfusion

 

function nochaoscode(str)
{
var new_str = “”;
for(i=1; i lte len(str);i=i+1){
if(asc(mid(str,i,1)) lt 128){
new_str = new_str & mid(str,i,1);
}else{
new_str = new_str & “&##” & asc(mid(str,i,1));
}
}
return new_str;
}

 


 

附:

在php中我們可以用mbstring的mb_convert_encoding函數(shù)實(shí)現(xiàn)這個(gè)正向及反向的轉(zhuǎn)化。 如:


mb_convert_encoding ("你好", "HTML-ENTITIES", "gb2312");    //輸出:你好
mb_convert_encoding ("你好", "gb2312", "HTML-ENTITIES");    //輸出:你好 

 

如果需要對(duì)整個(gè)頁(yè)面轉(zhuǎn)化,則只需要在php文件的頭部加上這三行代碼:

 

mb_internal_encoding("gb2312");  // 這里的gb2312是你網(wǎng)站原來(lái)的編碼
mb_http_output("HTML-ENTITIES");
ob_start(‘mb_output_handler‘); 


如果沒(méi)有打開(kāi)mbstring擴(kuò)展,可以參考coolcode.cn上的這兩篇文章:
在任意字符集下正常顯示網(wǎng)頁(yè)的方法
在任意字符集下正常顯示網(wǎng)頁(yè)的方法(續(xù))


 

2、HTML實(shí)體

 

HTML 4.01 支持 ISO 8859-1 (Latin-1) 字符集。

提示 實(shí)體名是區(qū)分大小寫(xiě)的。

備注 同一個(gè)符號(hào),可以用“實(shí)體名稱”和“實(shí)體編號(hào)”兩種方式引用,“實(shí)體名稱”的優(yōu)勢(shì)在于便于記憶,但不能保證所有的瀏覽器都能順利識(shí)別它,而“實(shí)體編號(hào)”則沒(méi)有這種擔(dān)憂,但它實(shí)在不方便記憶。
