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

Question

I am trying to take the elements on an array that contains a substring. For example:

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

And giving a string to look for str = "Ra" , I would like to create a new array only with {name: "Pablo Ramon", lastName: "Garcia"} after applying the filter.

If I am not wrong this is possible using a map but I do not know how to do it.

EDIT

My current structure is: Object

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

From the service

  betList: any;

The error that I get after using the next command is:

Command 1

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

Command 2

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

Error

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

Answer 1

You can filter array using .filter() and String's .includes() methods:

 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

Use a .filter() in simple way:

 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); 

Another solution without .includes() :

 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"}
