In the case of the Element component, complete selection, unselection, deselect

I wrote it basically as a theory. Mainly business code is trival and complex, difficult to thoroughly understand all on my own Now write a practical, a recent project, without use of the code generator and other components, is a blank page allows you to write in primary form, need to implement several functions, all, all pack up, all the choices, deselect, reverse choice

Select the appropriate component first, which is recommended

It is recommended to read through the following method first

deselect

Just copy element’s built-in methods. It smells good

if (rows) { rows.forEach(row => { this.$refs.multipleTable.toggleRowSelection(row); }); } else { this.$refs.multipleTable.clearSelection(); }},Copy the code

The other two methods are modified on a deselect basis

select all

checkAll() {
				
            this.tableData.forEach(item => {
	    this.$refs.multipleTable.toggleRowSelection(item, true);
				});
			},
Copy the code

The selected

Anti – select on the basis of all slightly modified on the line

invertSelection() {
			this.tableData.forEach(item => {
			this.$refs.multipleTable.toggleRowSelection(item);
				});
			}
Copy the code

After writing out, I found that it was actually very simple, but I spent a lot of effort to write
