jqgrid:data from the previous month can't appear - jquery-ui

Question

I don't know whats happen with my jqgrid,for the 1st time my data can show (all data which already input to database).
But, after I try to input date format from jquery datepicker like:
I choose 08/03/2011 but actual date is 09/09/2011.
the jqgrid can't display that data, but in database the data is already input.
could you tell why its happen?
EDIT
this is for the input page:
<script type="text/javascript" language="javascript" src="js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" language="javascript" src="js/jquery-ui-1.8.1.custom.min.js"></script>
<script type="text/javascript" language="javascript" src="js/jquery.datePicker-2.1.2.js"></script>
<script type="text/javascript" language="javascript" src="development-bundle/ui/jquery.ui.datepicker.js"></script>
<script>
$(function() {
$(".datepicker").datepicker({ dateFormat:'yy-mm-dd'});
});
</script>
<input type="text" id="datepicker" name="prob_date" class="datepicker">
and I get a downloaded folder jqgrid_demo38
and for the display page(use jqgrid):
<link rel="stylesheet" type="text/css" media="screen" href="jqGrid/css/ui.jqgrid.css" />
<link rel="stylesheet" type="text/css" media="screen" href="jqGrid/plugins/ui.multiselect.css" />
<script src="jqGrid/js/i18n/grid.locale-en.js" type="text/javascript"></script>
<script src="jqGrid/js/jquery.jqGrid.min.js" type="text/javascript"></script>
<script type="text/javascript" language="javascript" src="js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" language="javascript" src="js/jquery-ui-1.8.1.custom.min.js"></script>
i'm just can't show the data which not inputed in the current month.

Big guess here but I'm guessing you're trying to set a maxDate on your datepicker. If that's so, then the date you're passing to maxDate is probably not correct.
Here's what I suggest to create a consistent date object for your maxDate across the various browsers:
HTML:
<input name="datetime" class="datetime" type="text" data-maxdatetime="<YOUR MAX DATE FROM DB HERE>" value="<SOME PRE-SELECTED DATETIME>" />
JS:
var max_date = $(".datetime").data("maxdatetime");
$(".datetime").datepicker({
maxDate: parseISO8601(max_date)
});
/**
* http://jibbering.com/faq/#parseDate
* Parses string formatted as YYYY-MM-DD to a Date object.
* If the supplied string does not match the format, an
* invalid Date (value NaN) is returned.
* #param {string} dateStringInRange format YYYY-MM-DD, with year in
* range of 0000-9999, inclusive.
* #return {Date} Date object representing the string.
*/
function parseISO8601(dateStringInRange) {
var isoExp = /^\s*(\d{4})-(\d\d)-(\d\d)\s*$/,
date = new Date(NaN), month,
parts = isoExp.exec(dateStringInRange);
if(parts) {
month = +parts[2];
date.setFullYear(parts[1], month - 1, parts[3]);
if(month != date.getMonth() + 1) {
date.setTime(NaN);
}
}
return date;
}

It works....
I am Deleted some command in query:
$start = $limit*$page - $limit; // do not put $limit*($page - 1)
$SQL = "SELECT * FROM oqc_defect ORDER BY $sidx $sord /*LIMIT $start , $limit*/";
$result = mysql_query( $SQL ) or die("Couldnt execute query.".mysql_error());
I am disabled LIMIT from query.
But, I don't know why it can works..may be another reader can explain this.
