[Feature Request] Progress supporting customize text format

[imageslr]

Existing Component

是

Component Name

Progress

Description

当前进度条的 text 只支持显示百分比形式：75%，希望能够提供一个 format 属性，允许自定义文字格式，如：
<progress percent="75" format="$percent 折"></progress>
显示 “75折"。

format 属性还可以是回调函数的形式，其参数为当前百分比。

I hope I can customize the text format of Progress component, instead of only unique format "75%". For instance, the component provides format attribute and it can be String or Function. If it is a function, the argument will be current percent.

<progress percent="70" format="$percent 折"></progress>
and the text of the component will be 75折。

Translation of this issue:

Existing Component
yes

Component Name
Progress

Description
The text of the current progress bar only supports the display percentage form: 75%, it is hoped that it can provide a format attribute and allow custom text format, such as:

<progress percent= "75" format= "$percent fold" ></progress>
Show "25% off".

The format attribute can also be a form of callback function whose parameter is the current percentage.
I hope I can customize the text format of Progress component.

<progress percent= "70" format= "$percent fold" ></progress>
And the text of the component will be `75 fold.

动态 更新 format 会导致

You may have an infinite update loop in a component render function.

添加format属性或者slot都可以试验一下，在项目场景中我也遇到了这个需求
