标签：10 name 27jqGrid cell Client 2007 3.0 id 加载
这个例子演示了jqGrid的两个新功能。
-
loadComplete() callback -该方法是在执行加载数据后立即执行。
这样我们就可以根据不同的需求来做不同的变化修改。 -
新方法 getDataIDs() -返回当前加载数据的id列表。
这个方法可以与loadComplete回调方法组合来试用。

javascript代码举例
$(function(){

});
function pageInit(){
jQuery("#list15")
.jqGrid(
{
url : ctx+'/JSONData',
datatype : "json",
colNames : [ 'Inv No', 'Date', 'Client', 'Amount','Tax', 'Total', 'Notes' ],
colModel : [
{name : 'id',index : 'id',width : 55},
{name : 'invdate', index : 'invdate',width : 90},
{name : 'name',index : 'name',width : 100},
{name : 'amount',index : 'amount',width : 80,align : "right"},
{name : 'tax',index : 'tax',width : 80,align : "right"},
{name : 'total',index : 'total',width : 80,align : "right"},
{name : 'note',index : 'note',width : 150,sortable : false}
],
rowNum : 10,
rowList : [ 10, 20, 30 ],
pager : '#pager15',
sortname : 'id',
viewrecords : true,
sortorder : "desc",
loadComplete : function() {
var ret;
alert("这个方法是执行加载数据完成之后的回调方法。我们可以尝试在此之后更新第13行数据。");
ret = jQuery("#list15").jqGrid('getRowData', "13");
if (ret.id == "13") {
jQuery("#list15")
.jqGrid(
'setRowData',
ret.id,
{
note : "<font color='red'>Row 13 is updated!</font>"
})
}
}
});
jQuery("#sids").click(function() {
alert("Id's of Grid: \n" + jQuery("#list15").jqGrid('getDataIDs'));
});
}
