Angular Http Post By Sequence

Question

我有这样的数据，每次我发布它在我的数据库中的.it随机发布，如何按顺序发布它。要保存前12 > 13 > 14 >3

let regularBudgetStatus = [
{logicalFrameworkId,logFrameActionStatusReferenceId : 12,remarks : 'ACCEPTED->INCLUSION', actedByEIC },
{logicalFrameworkId,logFrameActionStatusReferenceId : 13,remarks : 'ACCEPTED->APPROPRIATION',actedByEIC },
{logicalFrameworkId,logFrameActionStatusReferenceId : 14, remarks : 'ACCEPTED->RECOMMENDATION', actedByEIC },
{logicalFrameworkId,logFrameActionStatusReferenceId : 3,remarks : 'ACCEPTED->AIP 1ST DRAFT', actedByEIC}
];


this.programservice.saveStatus(item)
.toPromise()
.then(
res => {console.log("success")})
.catch(() => console.log("error"));
});

您可以传递整个数组，然后从后端应用程序按顺序保存它们。但是如果你不能做到这一点，试试这个：

saveNextItem(i: number) {
    this.programservice.saveStatus(item) 
      .toPromise()
      .then(
        res => {
          console.log("success")
          if(i < regularBudgetStatus.length-1) this.saveNextItem(i++);
        })
      .catch(() => console.log("error"));
  }

然后只需调用saveNextItem(0)来按顺序保存整个数组。用regularBudgetStatusi.logFrameActionStatusReferenceId，更改'item‘变量我不是为了简单而更改它。
