自定义过滤器:我可以为过滤器设置自定义按钮吗? [英] Custom filter: can I have custom buttons for filter?

问题描述

我正在尝试在 ag-grid angular.
除了 Apply 按钮，我还想为过滤器添加其他按钮.即如果我可以在某种 UI 中解释这一点，

I am trying to have my own custom filter on ag-grid angular.
Apart from Apply button, I also want to have other buttons for the filter. i.e. if I can explain this in some sort of UI,

|--自定义过滤器-------------------.
|过滤文本:_____________ |
|申请 |清除 |清除所有|
|_______________________|

|--Custom Filter-------------------.
| Filter Text: _____________ |
| Apply | Clear | Clear All|
|_______________________|

通过使用ag-grid的默认过滤器组件，我知道如果我在ColDef中提供filterParams，我可以有两个我需要的按钮.

By using default filter component of ag-grid, I know that I can have two buttons I need if I provide filterParams in ColDef.

filterParams: {
    applyButton: true,
    clearButton: true
}

但是另一个自定义(Clear All)按钮呢?有什么办法可以实现吗?

But what about the other custom (Clear All) button? Is there any way I can achieve it?

推荐答案

经过几个小时的搜索和试错后实现.

Achieved it after few hours of search and trial-error.

看看这里给出的例子:ag-Grid Angular 自定义过滤器组件查看 PartialMatchFilterComponent 及其代码.

Have a look at the example given here: ag-Grid Angular Custom Filter Component Have a look at the PartialMatchFilterComponent and its code.

对模板和组件进行一些代码更新后，我们就可以实现了.

After some code updates for template and component, we can achieve it.

更新模板:

<button (click)="apply()">Apply</button>
<button (click)="clear()">Clear</button>
<!-- any other buttons you want to keep -->

组件代码中的小更新:只需在Apply按钮点击时调用this.params.filterChangedCallback().

Little update in the component code: Just need to call this.params.filterChangedCallback() on Apply button click.

apply(): void {
    this.params.filterChangedCallback();
}
clear(): void {
    this.text = '';
    this.params.filterChangedCallback();
}
onChange(newValue): void {
    if (this.text !== newValue) {
        this.text = newValue;
        // this.params.filterChangedCallback(); - remove
    }
}
