باسلام
من يك textfield به نام date_input دارم:
var TheData='<h3>گزارش كار</h3><br><br><table><tr><td><input type="checkbox" onclick="'+
'if(this.checked == true)'+
'document.getElementById(\'date\').style.visibilit y=\'visible\';'+
'if(this.checked == false)'+
'document.getElementById(\'date\').style.visibilit y=\'hidden\';" id="boxmission" />ماموريت </td>'+
'<td><div id="date" >'+
'<input id= "date_input" name="date_input" type="text" dir="ltr"/>';كه مي خواهم value اون رو به اين ترتيب با تابع trim حذف كنم:
var value=document.getElementById('date_input').value;
value=Trim(value);تابع trim درست عمل مي كنه ولي جهت اطمينان:
function LTrim(str)
{
var whitespace = new String(" \t\n\r\f");
var s = new String(str);
if (whitespace.indexOf(s.charAt(0)) != -1) {
// We have a string with leading blank(s)...
var j=0, i = s.length;
// Iterate from the far left of string until we
// don't have any more whitespace...
while (j < i && whitespace.indexOf(s.charAt(j)) != -1)
j++;
// Get the substring from the first non-whitespace
// character to the end of the string...
s = s.substring(j, i);
}
return s;
}
// --------------------------------------------------------------------------
// Remove trailing blanks from our string.
// I str - the string we want to RTrim
// Return the input string without any trailing whitespace

function RTrim(str)
{
// We don't want to trip JUST spaces, but also tabs,
// line feeds, etc. Add anything else you want to
// "trim" here in Whitespace
var whitespace = new String(" \t\n\r");
var s = new String(str);
if (whitespace.indexOf(s.charAt(s.length-1)) != -1) {
// We have a string with trailing blank(s)...
var i = s.length - 1; // Get length of string
// Iterate from the far right of string until we
// don't have any more whitespace...
while (i >= 0 && whitespace.indexOf(s.charAt(i)) != -1)
i--;
// Get the substring from the front of the string to
// where the last non-whitespace character is...
s = s.substring(0, i+1);
}
return s;
}
// --------------------------------------------------------------------------
// Remove trailing and leading blanks from our string.

function Trim(str)
{
return RTrim(LTrim(str));
}با اين وجود فضاي اطراف value همچنان وجود داره.:عصبانی++:
خيلي فوري
ممنون از راهنماييتون
