footerTemplateをKendoUIグリッドで動作させようとしています。表のフッターで「hours_worked」の合計を取得したいと思います。Kendo UIの例からいくつかのオプションを試しましたが、うまくいきません。何が間違っているのですか?
$(document).ready(function() {
$("#grid").kendoGrid({
dataSource: {
transport:
read: {
url: "mods/hours/data/get_hours.php?id=<?php echo $volunteer_id; ?>",
dataType: "json"
}
},
schema: {
model: {
fields: {
hours_id: { type: "number" },
volunteer_first_name: { type: "string" },
volunteer_last_name: { type: "string" },
hours_date: { type: "date" },
location_name: { type: "string" },
work_type_name: { type: "string" },
volunteer_id: { type: "number" },
hours_worked: { type: "number" }
}
}
},
aggregate:[{ field:"hours_worked", aggregate:"sum" }],
pageSize: 10
},
height: 350,
filterable: true,
sortable: true,
pageable: true,
selectable:true,
columns: [
{
title:"Naam",
template:"#=volunteer_last_name#, #=volunteer_first_name#",
},{
title:"Locatie",
field:"location_name",
},{
title:"Werkzaamheden",
field:"work_type_name",
},{
title:"Uren",
field:"hours_worked",
footerTemplate:"Sum: #=sum#",
},{
title:"Datum",
field:"hours_date",
},{
width:"200px",
title:"Opties",
filterable: false,
template:"<a href='?p=edit_reported_hours&id=#=volunteer_id#&hours_id=#=hours_id#' class='k-button'>Bewerken</a> <a href='?p=manage_reported_hours&o=delete&id=#=volunteer_id#&hours_id=#=hours_id#' class='k-button'>Delete</a>"
},
]
});
});
