如何从包含细分的对象数组中提取元素-Javascript和Angular 5

Question

我试图将包含子字符串的数组上的元素。 例如：

 myArray = [{name: "Pablo Ramon", lastName: "Garcia"}, {name: "Ernesto", lastName: "Salgado"}]

并给出一个字符串以查找str = "Ra" ，我想在应用过滤器后仅使用{name: "Pablo Ramon", lastName: "Garcia"}创建一个新数组。

如果我没记错，可以使用map但我不知道该怎么做。

编辑

我当前的结构是： 对象

export class Car{
  $key: string;
  title: string;
  description: string;
}

从服务

  betList: any;

使用下一条命令后出现的错误是：

命令1

 this.betList = this.betList.filter(o =>
   Object.values(o).some(s => s.includes(title))
 );

命令2

this.betList = this.betList.filter(o =>
   Object.values(o).some(s => s.indexOf(title) >= 0)
);

错误

 Property 'includes' does not exist on type '{} 

Answer 1

您可以使用.filter()和String的.includes()方法来过滤数组：

 let data = [{name: "Pablo Ramon", lastName: "Garcia"}, {name: "Ernesto", lastName: "Salgado"}]; let str = 'Ra'; let result = data.filter(o => Object.values(o).some(s => s.includes(str))); console.log(result); 

Answer 2

使用简单的.filter()方法：

 var data = [{ name: "Pablo Ramon", lastName: "Garcia" }, { name: "Ernesto", lastName: "Salgado" }]; var result = data.filter(o => Object.values(o).some(s => s.includes("Ra"))); console.log(result); 

没有.includes()另一种解决方案：

 var data = [{ name: "Pablo Ramon", lastName: "Garcia" }, { name: "Ernesto", lastName: "Salgado" }]; var result = data.filter(o => Object.values(o).some(s => s.indexOf("Ra") >= 0 )); console.log(result); 

Answer 3

[{name: "Pablo Ramon", lastName: "Garcia"}, {name: "Ernesto", lastName: "Salgado"}]
.filter (p => p.name.includes ('Ra'))

//{name: "Pablo Ramon", lastName: "Garcia"}
