Trim 함수 자바스크립트로 사용하기 입니다.
<script language="javascript">
function ltrim(value)
{
var LeftTrimValue = "";
var i=0;
if( value == "" )
return "";
strLen = value.length;
while(i<strLen)
{
if(value.charAt(i) != " ") break;
i++;
}
for(s=i;s<strLen;s++)
{
LeftTrimValue = LeftTrimValue + value.charAt(s);
}
return LeftTrimValue;
}
function rtrim(value)
{
var RightTrimValue = "";
if( value == "" )
return "";
strLen = value.length;
--strLen;
while( 0 <= strLen)
{
if(value.charAt(strLen) != " ") break;
--strLen;
}
for(s=0;s<=strLen;s++)
{
RightTrimValue = RightTrimValue + value.charAt(s);
}
return RightTrimValue;
}
function trim(value)
{
return rtrim(ltrim(value));
}
function test()
{
switch(eval(form.sel.value))
{
case 1 : alert("\"" + trim(form.ok.value) + "\"" ); break;
case 2 : alert("\"" + rtrim(form.ok.value) + "\"" ); break;
case 3 : alert("\"" + ltrim(form.ok.value) + "\"" ); break;
}
