问题描述
我需要一个 thousand separator input mask 指令或 Ionic 3 应用程序.我尝试了 2 个指令.但他们都没有工作.你知道这方面的工作指令吗?
I need a thousand separator input mask directive or else with Ionic 3 app. I have tried 2 directives. But none of them were working. Do you know working directive for that?
例如50,000
.html
<ion-input type="tel" [ngModel]="data?.budget" formControlName="budget" (ngModelChange)="data.budget=$event"></ion-input>
我在 Git 上记录了问题.也请看:

推荐答案
这是我的格式化版本，也适用于 ionic.
Here is my version of formatting that works on ionic too.
打字稿:
format(valString) {
if (!valString) {
return '';
}
let val = valString.toString();
const parts = this.unFormat(val).split(this.DECIMAL_SEPARATOR);
return parts[0].replace(/B(?=(?:d{3})+(?!d))/g, this.GROUP_SEPARATOR) + (!parts[1] ? '' : this.DECIMAL_SEPARATOR + parts[1]);
};
unFormat(val) {
if (!val) {
return '';
}
val = val.replace(/^0+/, '');
if (this.GROUP_SEPARATOR === ',') {
return val.replace(/,/g, '');
} else {
return val.replace(/./g, '');
}
};
HTML:
<ion-input [(ngModel)]="budget" pattern="^[$-s]*[d,]*?([.]d{0,10})?s*$"
style="border:1px solid black" #myBudget="ngModel" (input)="budget = format(budget)"></ion-input>
<p style="color:red" *ngIf="myBudget.errors && myBudget.errors?.pattern">Enter numbers only</p>
它需要在错误管理和货币添加方面进行一些改进(它接受前导$"符号).我将正则表达式设置为接受小数点后 10 位的数字.
It need some improvements in error management and currency addition (it accepts leading '$' sign). I set the regexp to accept numbers with 10 decimals.
演示
如果您不希望输入小数而只输入数字，则此 DEMO 展示了如何.
If you wish no decimals and only numeric input, this DEMO shows how.
