I’m dealing with a straightforward situation where I need to traverse a table of elements, click on each item, and input a value. In a typical browser setup, you can utilize QuerySelector
on the document or any node. For example:
const rows = document.querySelectorAll('.rows');
Then, to interact with elements within each row, you can do:
rows.forEach(item => {
item.querySelector('.item_1').click();
item.querySelector('.item_2').click();
item.querySelector('.item_3').click();
});
In my case, the JavaScript click method isn’t functioning properly, and I need to simulate a mouse click. In Puppeteer, I understand that you should use the page.click()
method, but Page
isn’t accessible in the browser environment like within page.evaluate()
or $$eval()
.
While I can retrieve elements similarly using const rows = page.$$('.rows');
, I’m uncertain how to loop through these to target second-level elements from the node as the reference for the next selection. Is it achievable in Puppeteer’s context? You can’t directly use:
page.click('.item_1');
since that would select the first row’s item. I wish to perform a CSS query in a manner akin to:
rows.forEach((item, page) => {
page.click(item.querySelector('.item_1'));
...
}, page);
Is this feasible? If yes, what would the correct syntax look like? Most responses I found revolve around using the JavaScript Click function rather than Puppeteer’s specific click functionality.
You can achieve this using Puppeteer’s evaluate
combined with node-specific operations. Here’s a straightforward solution:
const rows = await page.$$('.rows');
for (const row of rows) {
await row.$eval('.item_1', item => item.click());
await row.$eval('.item_2', item => item.click());
await row.$eval('.item_3', item => item.click());
}
This code selects all elements with the class .rows
, then iterates over these elements. For each row, it targets and clicks the specified items using .$eval
to interact with each element directly.
Yes, you can definitely achieve this using Puppeteer, and it requires employing page.$$()
and elementHandle.$eval()
for precise interactions with node-specific elements. Here’s a streamlined approach to accomplish your task efficiently:
const rows = await page.$$('.rows');
for (const row of rows) {
await row.$eval('.item_1', item => item.click());
await row.$eval('.item_2', item => item.click());
await row.$eval('.item_3', item => item.click());
}
Here’s how it works:
- Select Elements: Use
await page.$$('.rows')
to grab all elements matching the class .rows
.
- Iterate Efficiently: Loop through each element using a
for...of
loop to handle promise resolutions neatly.
- Direct Element Interaction: For each node,
.$eval()
lets you perform actions directly on second-level elements, simulating a real mouse click.
This practical method ensures you click on specific child elements within each .row
element, maintaining accuracy and optimized performance, akin to native browser interactions!
You can achieve the desired behavior with Puppeteer using page.$$()
and elementHandle.$eval()
. Here's a concise example:
const rows = await page.$$('.rows');
for (const row of rows) {
await row.$eval('.item_1', item => item.click());
await row.$eval('.item_2', item => item.click());
await row.$eval('.item_3', item => item.click());
}
This code grabs all elements with the class .rows
, iterates over them, and uses .$eval()
to click on specified child elements, enabling precise interaction with nested nodes.
