[英]How to get current row HTML Table cell element?
I have a angular material table.我有一张angular的材质表。 If I click one row, i wanted to fetch the HTMLTableCellElement of the selected row .
如果我单击一行,我想获取所选行的 HTMLTableCellElement。 I tried using viewChild but the problem is i am getting whole table html element.

In your example when you click on the a tag you can also send that tag to your function:在您的示例中,当您单击 a 标签时,您还可以将该标签发送到您的 function:
<mat-cell *matCellDef="let element" id="{{ element.position }}">
<a href="javascript:;" (click)="viewhtmlData($event.target)">{{
element.name
}}</a>
</mat-cell>
Then, inside your function you can get the parent of that a tag which is the mat-cell containing it, like so:然后,在您的 function 中,您可以获得该标签的父级,该标签是包含它的 mat-cell,如下所示:
viewhtmlData(aTag: HTMLElement) {
console.log('Selected Row HtML data', aTag.parentElement);
}
<!-- CONSOLE OUTPUT -->
<mat-cell _ngcontent-c69="" class="mat-cell cdk-column-name mat-column-name" role="gridcell" id="3">
<a _ngcontent-c69="" href="javascript:;">Lithium</a>
</mat-cell>
There are two changes you can make from the sample you have provided.您可以根据您提供的示例进行两项更改。
Change: 1 (in.html side) Pass event via the function: viewhtmlData()更改:1(in.html 端)通过 function 传递事件:viewhtmlData()
<a href="javascript:;" (click)="viewhtmlData()">{{ element.name }}</a>
to到
<a href="javascript:;" (click)="viewhtmlData(element)">{{ element.name }}</a>
Change 2:(in.ts side) Pass the element through the function更改 2:(in.ts 端)通过 function 传递元素
// This function will show entire table contents
viewhtmlData() {
console.log('Selected Row HtML data',this.table);
}
to到
// The element data from .html is passed through the function
viewhtmlData($event) {
console.log('Selected Row HtML data',$event);
this.selectedElement =$event;
var Row = document.getElementById($event.position) as HTMLTableCellElement;
this.selectedCellHtml = Row;
console.log('Selected Row HtML data',this.selectedCellHtml);
}
