如何删除 w2grid (W2UI) 中的选定记录

Question

I want to delete selected records in a grid of the W2UI library, for which I am using w2grid ( https://w2ui.com/web/docs/2.0/grid ). My grid is called 'divInfoConfig' .

I have created a dynamic grid through a JSON.

What would I like to do?

I have a button with the removeSelectedRecords() function, which should behave that if I manually select 1 or more than 1 record, hitting the button should remove them.

How have I tried?

The function removeSelectedRecords() does the following:

function removeSelectedRecords() {
    var sel = w2ui['divInfoConfig'].getSelection();
    console.log('Selection: ' + sel);
    if (sel) {
        delete sel;
    }
    w2ui['divInfoConfig'].refresh();
}

The button is as follows:

<button class="w2ui-btn" onclick="removeSelectedRecords();">Remove Selected Records</button>

This is what the console log returns

Selection: 6,7

This is because I selected 2 records.

The problem:

The button does nothing. It should delete the selected records.

Any idea on what I am doing wrong?

Answer 1

You are using the native JS delete operator . You should be using w2ui delete() .

So in your case it's:

function removeSelectedRecords() {
    var sel = w2ui['divInfoConfig'].getSelection();
    console.log('Selection: ' + sel);
    if (sel) {
        w2ui.grid.delete(sel);
    }
    w2ui['divInfoConfig'].refresh();
}
