HTML编码转换、HTML部分实体

网页中的字符编码：

1、编码转换（to Unicode）

（程序代码来源于网络）

 

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版

 

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中我们可以用mbstring的mb_convert_encoding函数实现这个正向及反向的转化。 如：

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

 

如果需要对整个页面转化，则只需要在php文件的头部加上这三行代码：

 

mb_internal_encoding("gb2312");  // 这里的gb2312是你网站原来的编码
mb_http_output("HTML-ENTITIES");
ob_start(‘mb_output_handler‘); 

如果没有打开mbstring扩展，可以参考上的这两篇文章：

2、HTML实体

 

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

提示 实体名是区分大小写的。

备注 同一个符号，可以用“实体名称”和“实体编号”两种方式引用，“实体名称”的优势在于便于记忆，但不能保证所有的浏览器都能顺利识别它，而“实体编号”则没有这种担忧，但它实在不方便记忆。
