[英]How can I refresh “footer” on Kendo Ui Grid using JQuery
I Set Kendo Ui Grid and footer, footer will get total price, but it always can't get last data.我设置了Kendo Ui Grid和footer,footer会得到总价,但是总是拿不到最后的数据。 hope somebody can help to fix it.希望有人可以帮助修复它。 and i try $("#Grid").data("kendoGrid").refresh();我尝试 $("#Grid").data("kendoGrid").refresh(); but it didn't work for me.但它对我不起作用。

I'm not sure If i does not described correctly,so i record video https://imgur.com/mePv5qI我不确定如果我没有正确描述,所以我录制视频https://imgur.com/mePv5qI
How can i do will be correct我该怎么做才会正确
Why are you using fetch()
?你为什么使用fetch()
? It seems that you don't need it, since you're not updating data from api.似乎您不需要它,因为您没有从 api 更新数据。 You're only updating local data, right ?你只是更新本地数据,对吧? So remove it and change dataItem
directly:所以删除它并直接更改dataItem
:
var row = $(this).closest("tr"),
grid = $("#AddGrid").data("kendoGrid"),
dataItem = grid.dataItem(row);
dataItem.txtReturnNum = dataItem.txtReturnNum - (-1);
dataItem.txtPriceNum = dataItem.txtReturnNum * dataItem.txtPrice;
dataItem.txtPriceNum1 = mulFloat(dataItem.txtReturnNum, dataItem.txtPricetax);
$("#AddGrid").data("kendoGrid").refresh();
Or或者
var row = $(this).closest("tr"),
grid = $("#AddGrid").data("kendoGrid"),
dataItem = grid.dataItem(row);
dataItem.set('txtReturnNum', dataItem.txtReturnNum - (-1));
dataItem.set('txtPriceNum', dataItem.txtReturnNum * dataItem.txtPrice);
dataItem.set('txtPriceNum1', mulFloat(dataItem.txtReturnNum, dataItem.txtPricetax));
