如何使用角度替换删除逗号

Question

here's the code: https://stackblitz.com/edit/angular-w5ecbw?file=src/app/app.component.ts

item.component.ts

ngOnInit() {
    const data = ['.23.2 ms','.23.001 ms', '.23.81 ms', '192,101.02 ms', '1291,291.02 ms'];
    for (let x = 0; x <= data.length; x++) {
      console.log(this.formatData(data[x].replace(/ .+/, '')))
    }
  }
  formatData(num: any) {
    const [num1, num2] = String(num).split('.');
    if (!num2) {
      return num1;
    } else {
      return `${num1}.${num2}`;
    }
  }

expected output should be:

.23.2
.23.001
    .23.81
    192101.02
    1291291.02

What I want to do here is to remove the comma.

Answer 1

Try this.

 const data = ['.23.2 ms','.23.001 ms', '.23.81 ms', '192,101.02 ms', '1291,291.02 ms']; const result = data.map( item => item.replace(/,|[^0-9\\.]|/g, "")); console.log(result.join(", "));

Answer 2

你可以像这样删除它：

string.replace(',', '');

Answer 3

User map , split , replace and join methods.

 const data = [ ".23.2 ms", ".23.001 ms", ".23.81 ms", "192,101.02 ms", "1291,291.02 ms" ]; updated = data.map(x => x.split(" ms")[0].replace(",", "")).join(''); console.log(updated);
