网页中的字符编码(html的unicode实体编码)

1、编码转换（to Unicode）

<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>

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

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;
}
