js function for converting half-width and full-width to each other_javascript skills

Copy code The code is as follows:

///Full-width spaces are 12288, half-width spaces are 32
///The corresponding relationship between half-width (33-126) and full-width (65281-65374) of other characters is: the difference is 65248
//Half-width to full-width function
function ToDBC(txtstring)
{
var tmp = "";
for(var i=0;i{
if(txtstring.charCodeAt(i)==32)
{
tmp= tmp String.fromCharCode(12288);
}
if(txtstring.charCodeAt(i)<127)
{
tmp=tmp String.fromCharCode(txtstring.charCodeAt(i) 65248);
}
}
return tmp;
}
//Convert full-width to half-width function
function ToCDB(str)
{
var tmp = " ";
for(var i=0;i{
if(str.charCodeAt(i)>65248&&str.charCodeAt(i)<65375)
{
tmp = String.fromCharCode(str.charCodeAt(i)-65248);
}
else
{
tmp = String.fromCharCode(str.charCodeAt(i));
}
}
return tmp
