JSON AJAX返回“未定义”

Question

Im trying to get a simple json on my ajax to asign the values to some inputs on my page, but i always get a undefined on my ajax alert

This is my JSON:

{"data":[{"Line_Number":10,"PO_Number":"P072592-1","Date":"9-07-17","Item_Number":"12789 - ","Size":"S","Description":"HDW- HINGE- PIANO- BLACK STAINLESS- .125 DIA.- HD SERIES","Delivery":"12-18-17","Quantity":800.0000,"Unit":"PCS","Unit_Price":0.8600,"Amount":"688"}]}

And this is my Ajax Call:

$.ajax({
    type: "GET",
    dataType: "json",
    url: '@Url.Action("GetOrder","Orders")/' + val,
    //data: { po_number: 'value' },
    success: function (data) {
        alert(data[0].Date)
    },
    error: function () {
         alert('Some error occurred!');
    }
});

However i always get a Undefined on my alert and what i need is my "Date" Value What am i doing wrong?

Answer 1

As I see your data is

{"data":[{"Line_Number":10,"PO_Number":"P072592-1","Date":"9-07-17","Item_Number":"12789 - ","Size":"S","Description":"HDW- HINGE- PIANO- BLACK STAINLESS- .125 DIA.- HD SERIES","Delivery":"12-18-17","Quantity":800.0000,"Unit":"PCS","Unit_Price":0.8600,"Amount":"688"}]}

so you should try this once

data.data[0].Date
