[wenbo_ying]

function trim(inString)
{
var l,i,g,t,r;
inString=new String(inString);
l=inString.length;
t=inString;
for(i=0;i<l;i++)
{
g=inString.substring(i,i+1);
if(g==" ")
{
t=inString.substring(i+1,l);
}
else
{
break;;
}
}
r=t;
l=t.length;
//Delete the spaces back
for(i=l;i>0;i--)
{
g=t.substring(i,i-1);
if(g==" ")
{
r=t.substring(i-1,0);
}
else
{
break;
}
}
return(r);
}
