У меня проблема с перезагрузкой сетки с помощью триггера ('reloadGrid').Я отправляю AJAX-вызов на сервер, и сервер просто возвращает строку xmlstring.но сетка не загружает новые данные.вот мой код:
$('#tasks').jqGrid({
datatype: "xmlstring",
datastr: <?php echo json_encode($_xml); ?>,
colNames: ["Date","TaskID","Subject","Notes","Due Date"],
colModel: [
{name: "Date", index:"AssignDate",align: "center", xmlmap:"AssignDate"},
{name: "TaskID", index:"TaskID",xmlmap:"TaskID", align:"center"},
{name: "Subject", index:"TaskSubject", align: "center", xmlmap:"TaskSubject"},
{name:"Notes", index:"Notes", align: "center",height: 20,xmlmap:"Notes"},
{name:"Due Date", index:"DueDate", align: "center",height: 20,xmlmap:"DueDate"}
],
height: 250,
viewRecords: true,
autowidth: true,
xmlReader: {
root: "tasks",
row: "task",
repeatitems: false
},
pager: $('#navTasks'),
caption: "Your Tasks"});
setInterval(
function(){
$.ajax({
url: 'register.php',
data: {uID:uID},
dataType: 'xmlstring',
success: function(xml)
{
$("#tasks").setGridParam({datastr: xml, datatype: "xmlstring"}).trigger('reloadGrid')
}
});},10000);
вот мой файл register.php:
$uID = $_GET['uID'];
$host="127.0.0.1:3306";
$db_name='wf_db';
$tbl_name="tasks";
$connect = new mysqli("$host","root"," ","$db_name")or die('Can\'t connect to database!');
$sql = "SELECT * FROM $tbl_name WHERE UserID='$uID' and Task_Completed='0'";
$query_data = mysqli_query($connect,$sql)or die('Couldnt get data');
$row = mysqli_num_rows($query_data);
if($row != 0){
$_xml = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>\r\n";
$_xml .="<tasks>\r\n";
while ($result = mysqli_fetch_array($query_data)) {
if ($result["TaskID"]) {
$_xml .="\t<task>\r\n";
$_xml .="\t\t<TaskID>" . $result["TaskID"] . "</TaskID>\r\n";
$_xml .="\t\t<UserID>" . $result["UserID"] . "</UserID>\r\n";
$_xml .="\t\t<AssignID>" . $result["AssignID"] . "</AssignID>\r\n";
$_xml .="\t\t<AssignDate>" . $result["Assign_Date"] . "</AssignDate>\r\n";
$_xml .="\t\t<DueDate>" . $result["Due_Date"] . "</DueDate>\r\n";
$_xml .="\t\t<AssignUser>" . $result["Assign_User"] . "</AssignUser>\r\n";
$_xml .="\t\t<TaskSubject>" . $result["Task_Subject"] . "</TaskSubject>\r\n";
$_xml .="\t\t<Notes>" . $result["Notes"] . "</Notes>\r\n";
$_xml .="\t\t<TrackID>" . $result["TrackID"] . "</TrackID>\r\n";
$_xml .="\t\t<Details>" . $result["Completion_Details"] . "</Details>\r\n";
$_xml .="\t</task>\r\n";
} else {
$_xml .="\t<task>\r\n";
$_xml .="\t\t<TaskID></TaskID>\r\n";
$_xml .="\t\t<UserID></UserID>\r\n";
$_xml .="\t\t<AssignID></AssignID>\r\n";
$_xml .="\t\t<AssignDate></AssignDate>\r\n";
$_xml .="\t\t<DueDate></DueDate>\r\n";
$_xml .="\t\t<AssignUser></AssignUser>\r\n";
$_xml .="\t\t<TaskSubject></TaskSubject>\r\n";
$_xml .="\t\t<Notes></Notes>\r\n";
$_xml .="\t\t<TrackID></TrackID>\r\n";
$_xml .="\t\t<Details></Details>\r\n";
$_xml .="\t</task>\r\n";
}
}
$_xml .="</tasks>";
echo json_encode($_xml);
}
else {
echo 'Oops something went wrong!';
}
