How to simulate mouse click/key stroke to choose how many listings per page in Puppeteer?

Question

I have difficulty to simulate the mouse click/key stroke to choose how many lists per page after page.goto() . Here is the HTML source code for the per page option:

<label class="control-label pull-right" style="margin-right: 10px; font-weight: 100;">
    <small>Show</small>&nbsp;
    <select class="input-sm grid-per-pager" name="per-page">
        <option value="https://www.mysite-com/admin/order?per_page=10" >10</option>
        <option value="https://www.mysite-com/admin/order?per_page=20" selected>20</option>
        <option value="https://www.mysite-com/admin/order?per_page=30" >30</option>
        <option value="https://www.mysite-com/admin/order?per_page=50" >50</option>
        <option value="https://www.mysited-com/admin/order?per_page=100" >100</option>
    </select>
    &nbsp;<small>Piece</small>
</label>

The default is 20 listings per page, and I would like to change it to 100 listings per page which requires mouse click the box and hit down arrow key twice to choose 100 . Here is some code for the purpose:

await page.mouse.click("label.control-label .grid-per-pager");
await page.keyboard.press("ArrowDown");
await page.keyboard.press("ArrowDown");

It gave me a few errors. What is missing here?

Answer 1

page.select()

The best method to use in this case is page.select() .

This method accepts the selector for the select element as the first parameter and the value of the option you would like to select as the second parameter:

await page.select('select[name="per-page"]', 'https://www.mysited-com/admin/order?per_page=100');
