为什么 jquery 返回 [object][object] 值？

Question

Problem: When output is Getting that time value in text box is [object][object]

Jquery code:

    function EditDirectWarping() {
    var dwviewmodel;
    dwviewmodel =
     {
         DirectWarping: {

             DispoNo: 12346,



         }
     }
    CallAjax("/Production/Get_DirectWarpingData", "json", JSON.stringify(dwviewmodel), "POST", "application/json", false, DirectWarping_CallBackMethod, "", null);
}


function DirectWarping_CallBackMethod(data) {

    $("#txtgrosswt").val($(this).val(data.DirectWarping.Gross_Wt)),

    $("#txtnetwt").val($(this).val(data.DirectWarping.Net_Wt)),

    $("#txtwarpingmachine").val($(this).val(data.DirectWarping.Warping_Machine)),

    $("#txtwarpingmachinespeed").val($(this).val(data.DirectWarping.Warping_Machine_Speed)),

    $("#txtprogramcheckedby").val($(this).val(data.DirectWarping.Program_Checked_By)),

    $("#txtprogramgivenby").val($(this).val(data.DirectWarping.Program_Given_By)),

    $("#txtoperatorremark").val($(this).val(data.DirectWarping.Operators_Remark)),

    $("#txtwastage").val($(this).val(data.DirectWarping.Wastage)),

    $("#txtjumbobeammtrs").val($(this).val(data.DirectWarping.Jumbo_Beam_Mtrs)),

    $("#txtpressurerollpressure").val($(this).val(data.DirectWarping.Pressure_Roll_Pressure))

}

When output is Getting that time value in text box is [object][object]

Answer 1

When JavaScript prints [object Object] , it means you are trying to output an object instead of a string or number.

To display a date object as a string, use:

theDateObject.toString();

Answer 2

As a example

Instead of this:

$("#txtnetwt").val($(this).val(data.DirectWarping.Net_Wt)),

Write this(correct answer): $("#txtnetwt").val(data.DirectWarping.Net_Wt)

Answer 3

The conversion of string to object returns [Object object] so instead use: $.trim(yourObjectOrElement.val())

This .val() returns a string ;
