This example show how we can load JSON data with custom data type functon
i.e. the data is obtained not with the url parameter but with custom function.
HTML
<![CDATA[
...
<table id="listdt" class="scroll"></table>
<div id="pagerdt" class="scroll" style="text-align:center;"></div>
<script src="datatype.js" type="text/javascript"> </script>

Java Scrpt code

...
jQuery("#listdt").jqGrid({
//url:'server.php?q=2',
datatype : function (pdata) {
$.ajax({
url:'server.php?q=2',
data:pdata,
dataType:"json",
complete: function(jsondata,stat){
if(stat=="success") {
var thegrid = jQuery("#listdt")[0];
thegrid.addJSONData(eval("("+jsondata.responseText+")"))
}
}
});
},

PHP with MySQL
