我正在通过发送对象来执行POST请求,但出现错误错误
TypeError:无法设置未定义的属性“ ItemCode”
我正在将Angular 7与打字稿一起使用
这是我的初始化Json
objEnvio:any = <any> {
DocumentLines:<any>[]
};
这是我的代码:
Cadastrar() {
var today = new Date();
var self = this;
this.objEnvio.CardCode = something;
this.objEnvio.DocDueDate = something;
this.objEnvio.BPL_IDAssignedToInvoice = something;
$('.table-servico .mat-row').each(function(index, element){
self.objEnvio.DocumentLines[index].ItemCode =something; // this line is throwing the error
预期结果:
{
"CardCode": "C000009",
"DocDueDate": "2019-04-25",
"BPL_IDAssignedToInvoice": 1,
"DocumentLines": [
{
"ItemCode": "IT0001",
"UnitPrice": 207,
"Quantity": 4,
"TaxCode": "1101-001",
},
{
"ItemCode": "SV0003",
"UnitPrice": 110,
"Quantity": 1,
"TaxCode": "1933-001",
},
]
}
当前实际结果:
TypeError:无法设置未定义的属性“ ItemCode”
答案 0 :(得分:0)
现在可以使用,只需添加另一个
objEnvio:any = <any>{
DocumentLines:<any>[
<any>{
}
]
};
