javascript - toLocaleString() 不工作

Question

更新:

原文:

你能告诉我为什么 toLocaleString() 在这里不起作用吗？它适用于所有其他地方。我需要它来提供 1000 个分隔符。任何线索或解决方法？

 forEach(budgetList, async (b: Budget) => {
          const budget: Budget = find(this.oldBudgetList, (budget: Budget) => {
            return b.budgetGroup.name == budget.budgetGroup.name;
          });
          if (budget == null) {//new item
            const log = this.logProvider.getLogDetails(`Budget : ${b.budgetGroup.name}`, `Added ${b.amount.toLocaleString()}`, 'project', project.id);
            await this.logProvider.createLog(log, project.id);//add log
          } 
        });

运行时:

另一个地方，效果很好!

const log = this.logProvider.getLogDetails('Project : Budget', `Budget changed from ${this.oldBudgetValue.toLocaleString()} to ${project.budget.toLocaleString()}`, 'project', project.id);
await this.logProvider.createLog(log, project.id);//add log

Answer 1

如果该值是 String 类型，您可以执行以下操作

Number(b.amount).toLocaleString()

(这是在 OP 的案例中起作用的)

其他选项可能是

parseInt('number as string').toLocaleString()

parseFloat('number as string').toLocaleString()
