Angular - 仅打印 ag-Grid 数据

Question

我正在尝试以角度为 ag-Grid 使用打印功能。我的页面包含内容和 ag-Grid 数据。随便如果我应用打印功能，内容和网格数据都将用于打印。但我不确定如何只提供用于打印的 ag-Grid 数据。如果有人有想法，请帮助我。提前致谢。

这是根据文档的打印功能代码。

import { Component, ViewChild } from "@angular/core";
import "ag-grid-enterprise";

@Component({
  selector: "my-app",
  template: `


<button (click)="onBtPrint()">Print</button>

<ag-grid-angular
    #agGrid

这里的页面也包含带有内容的网格数据。现在如何仅发送 ag-grid 进行打印。

Answer 1

你的打印功能只能是这个

function setPrinterFriendly(api) {
    api.setDomLayout("print");
}

并使用这个 CSS：

@media print {
  body * {
    visibility: hidden;
  }
  #myGrid, #myGrid * {
    visibility: visible;
  }
  #myGrid {
    position: absolute;
    left: 0;
    top: 0;
  }
}
