javascript去空格，绝对好用
//调用:
var s=" dss ";
s=trim(s);
alert(s)
//调用以下程序
function trim(s){
s=removebeforechar(s);
s=removeafterchar(s);
return s;
}
//去前空格
function removebeforechar(t)
{
if(t.charCodeAt(0)==32 || t.charCodeAt(0)==12288)
{
t=t.slice(1,t.length);
return removebeforechar(t);
}
else
{
return t;
}
}
//去后空格
function removeafterchar(t)
{
if(t.charCodeAt(t.length-1)==32 || t.charCodeAt(t.length-1)==12288)
{
t=t.slice(0,t.length-1);
return removeafterchar(t);
}
else
{
return t;
}
