如何在单击列中的图像时突出显示 PrimeNG 数据表行? [英] How to highlight a PrimeNG datatable row on click of an image in the column?

问题描述

我有 10 列的 PrimeNG 数据表.最后一列包含图像.单击图像时，我必须突出显示该行.

I have PrimeNG datatable with 10 columns. Last column contains images. On click of the image I have to highlight the row.

如果我在数据表中添加选择模式单一"，单击行时它会突出显示该行.我不要那个.我希望它仅在用户单击最后一列的图像时突出显示.

If I add selection mode 'single' in the datatable, on click of row it highlights the row. I do not want that. I want it to be highlighted only when the user clicks on the image at the last column.

<p-column>
        <ng-template let-row="rowData" pTemplate type="body">
          <img src="assets/images/info_icon.jpg" style="height:20px;width:20px">
        </ng-template>
  <p-column>

推荐答案

您需要做的是在您的图像上设置一个 click 事件，该事件将切换关联行的属性.我们将该属性称为 isSelected.

What you have to do is to set a click event on your image that will toggle a property of the associated row. Let's call that property isSelected.

图像列的 HTML 代码变为

Your HTML code for your image column becomes

<p-column field="isSelected" header="" [style]="{'width':'32px','cursor': 'pointer'}">
  <ng-template pTemplate="body" let-rowData="rowData">
    <img src="https://image.flaticon.com/icons/svg/106/106705.svg" (click)="rowData.isSelected=!rowData.isSelected"/>
  </ng-template>
</p-column>

然后将 rowStyleClass PrimeNG 属性添加到您的 p-dataTable 中，这将调用一个函数，我们将其命名为 isRowSelected

Then add the rowStyleClass PrimeNG property to your p-dataTable which will call a function, let's name it isRowSelected

<p-dataTable [value]="cars" [rowStyleClass]="isRowSelected">

isRowSelected 函数将返回一个类名，具体取决于您是选择还是未选择该行

The isRowSelected function will return a class name, depending on if you selected or unselected the row

isRowSelected(rowData: any) {
  return (rowData.isSelected) ? "rowSelected" : "rowUnselected";
}

最后，创建这两个 CSS 类:rowSelected 和 rowUnselected

Finally, create these two CSS classes : rowSelected and rowUnselected

tr.rowUnselected > td {
  color: black;
  background-color: white !important;
}

tr.rowSelected > td {
  color: black;
  background-color: #dff0d8 !important;
}
