I have Puppeteer setup, and I was able get all of the rows using:
let rows = await page.$$eval('#myTable tr', row => row);
Now I want for each row to get "td
's" and then get the innerText
from those.
Basically I want to do this:
var tds = myRow.querySelectorAll("td");
Where myRow
is a table row, with Puppeteer.
One way to achieve this is to use evaluate that first gets an array of all the TD
s then returns the textContent
of each TD
:
const puppeteer = require('puppeteer');
const html = `
<html>
<body>
<table>
<tr><td>One</td><td>Two</td></tr>
<tr><td>Three</td><td>Four</td></tr>
</table>
</body>
</html>`;
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto(`data:text/html,${html}`);
const data = await page.evaluate(() => {
const tds = Array.from(document.querySelectorAll('table tr td'))
return tds.map(td => td.innerText)
});
//You will now have an array of strings
//[ 'One', 'Two', 'Three', 'Four' ]
console.log(data);
//One
console.log(data[0]);
await browser.close();
})();
You could also use something like:
const data = await page.$$eval('table tr td', tds => tds.map((td) => {
return td.innerText;
}));
//[ 'One', 'Two', 'Three', 'Four' ]
console.log(data);
