[英]How can I get the sum of the properties in the datasource?
我在C#中有一個模型項,如下所示:
public class ProjectDashBoardModel
{
public decimal Budget { get; set; }
public decimal Amount { get; set; }
public decimal Balance { get; set; }
public decimal Tax { get; set; }
public decimal Money1 { get; set; }
public decimal Money2 { get; set; }
public decimal Balance_2 { get; set; }
public decimal Balance_3 { get; set; }
}
public class ProjectDashboard
{
public Guid Id { get; set; }
public string ProjectLogo { get; set; }
public string LastMutatedBy { get; set; }
public DateTime LastMutatedDate { get; set; }
public List<ProjectDashBoardModel> ProjectModelList { get; set; }
}
這是我的數據源代碼:
vm.dataTotal = data.projectModelList;
我想擁有所有屬性的總和
我已經嘗試過類似的方法,但是沒有成功
vm.dataTotal = data.projectModelList(function () {
{field: "budget", aggregate: "sum"}
});
我已經在劍道網格中有此列表。 現在,我希望將網格中的預算總和添加到新的數據源中,以便將其與kendo條形圖綁定。
如何將所有屬性的總和放入vm.dataTotal?
親切的問候
如果要在JS
獲取數組的總和,則最好使用Array.prototype.reduce
:您可以在任意位置使用結果( total
變量),例如'vm.set('total',total) will bind it to your observable
虛擬機對象。
var data = { projectModelList: [ { "budget": 245, "amount": 500 , "balance": 2323, "tax": 234, "money1": 23, "money2": 6345, "balance_2": 123123, "balance_3": 3423}, { "budget": 245, "amount": 500 , "balance": 2323, "tax": 234, "money1": 23, "money2": 6345, "balance_2": 123123, "balance_3": 3423}, { "budget": 245, "amount": 500 , "balance": 2323, "tax": 234, "money1": 23, "money2": 6345, "balance_2": 123123, "balance_3": 3423}, { "budget": 245, "amount": 500 , "balance": 2323, "tax": 234, "money1": 23, "money2": 6345, "balance_2": 123123, "balance_3": 3423}, ] }; var total = data.projectModelList.reduce(function(t, d) { Object.keys(t).forEach(function(k) { t[k] += (d[k] || 0); }); return t; }) console.log(total)
