如何检查字段是否填充了cordova / angular

Question

我在我的控制器中有一个问题，我已经为我的数据填写了我的cordova应用程序。 但是如果所有字段都是空的，它仍会将其插入数据库中。

这是我目前的代码。

控制器范围（添加功能）

$scope.addInvoice = function(){
    console.log($scope.fileToUpload);
    var formdata = new FormData();
    var filedata = $scope.dataURLtoFile("data:image/jpeg;base64," + $rootScope.scan, 'scan.png');
    formdata.append("title", "Factuur " + $scope.factuurNr);
    formdata.append("imageselect", filedata);
    formdata.append("command", "Invoices:uploadImage");
    $.ajax({
    type: 'POST',
    url: gateway,
    data: formdata,
    mimeType: "multipart/form-data",
    cache: false,
    processData: false,
    contentType: false,
        success: function (data) {
            swal("Geweldig!", "de bon is succesvol toegevoegd", "success");
            data = JSON.parse(data);
            $scope.docGuid = data.data;
            $scope.$apply();
            // addInvoice \\
            // $ticket = $_POST['invoiceno'] ?: $_POST['ticket'] ?: null;
            // $totInclVat = $_POST['totamount'] ?: $_POST['totInclVat'] ?: null;
            // $docGuid = $_POST['docGuid'] ?: $_POST['docguid'] ?: null;
            // $vatLow = $_POST['vatLow'] ?: $_POST['vatlow'] ?: null;
            // $vatHigh = $_POST['vatHigh'] ?: $_POST['vathigh'] ?: null;
            // echo $api->addInvoiceOut($ticket, $_POST['company'], $_POST['person'], $totInclVat, $vatLow, $vatHigh, $_POST['concerns'], $docGuid);
            //END//
            if($scope.newContact){
                var type = "Bedrijf";
                var company = $scope.inputCompany;
                var formdata = $("").serializeArray();
                formdata.push({"name": "firstName", "value": company});
                formdata.push({"name": "type", "value": type});
                formdata.push({"name": "command", "value": "Contacts:add"});
                $.post(gateway, formdata, function (data) {
                    console.log(data);
                    var companyGuid = data.data;
                    var formdata = $("#bonForm").serializeArray();
                    formdata.push({"name": "company", "value": companyGuid});
                    formdata.push({"name": "docGuid", "value": $scope.docGuid});
                    formdata.push({"name": "person", "value": ""});
                    formdata.push({"name": "vatLow", "value": ""});
                    formdata.push({"name": "vatHigh", "value": ""});

                    formdata.push({"name": "command", "value": "Invoices:addInvoiceOut"});
                    $.post(gateway, formdata, function (data) {
                        console.log(data);
                        //admin_lifecycle
                        formdata.pop();
                        formdata.push({
                        "name": "vatcat",
                        "value": 0
                        });
                        formdata.push({

                        });
                        formdata.push({
                        "name": "vat",
                        "value": 0
                        });
                        formdata.push({
                        "name": "command",
                        "value": "Invoices:addLifecycleLine"
                        });
                        $.post(gateway, formdata, function (data) {
                            console.log(data);
                        }, "json");
                    }, "json");
                }, "json");
            }else{
                var formdata = $("#bonForm").serializeArray();
                formdata.push({"name": "company", "value": $scope.selectedCompany.guid});
                formdata.push({"name": "docGuid", "value": $scope.docGuid});
                formdata.push({"name": "person", "value": ""});
                formdata.push({"name": "vatLow", "value": ""});
                formdata.push({"name": "vatHigh", "value": ""});
                formdata.push({"name": "billingStatus", "value": "60"});
                formdata.push({"name": "command", "value": "Invoices:addInvoiceOut"});
                $.post(gateway, formdata, function (data) {
                    console.log(data);
                    // swal("Geweldig!", "de bon is succesvol toegevoegd", "success");
                    //admin_lifecycle
                    formdata.pop();
                    formdata.push({
                    "name": "vatcat",
                    "value": 0
                    });
                    formdata.push({
                    "name": "exvat",
                    "value": 0
                    });
                    formdata.push({
                    "name": "vat",
                    "value": 0
                    });
                    formdata.push({
                    "name": "command",
                    "value": "Invoices:addLifecycleLine"
                    });
                    $.post(gateway, formdata, function (data) {
                        console.log(data);
                    }, "json");
                }, "json");
            }
        }
    });
}
});

这是输入（FRONT）

        </div>
    </div>
</form>

我希望有人可以帮我建一张支票。 如果数据给出错误0，则字段填写正确。

您需要编辑使用jQuery声明serializeArray()变量的JavaScript行（在if和else ）。 你有过：

var formdata = $("").serializeArray();

相反，它应该是这样的：

var formdata = $("input[value!=''],checkbox[value!=''],radio[value!=''],select[value!='']").serializeArray();
