问使用Puppeteer将iFrame中的元素作为目标

EN

await page.waitForSelector("body > div.body.clearfix.container_20 > div.main.grid_12 > iframe");
            // need to target IFRAME

            const frameHandle = await page.$('iframe[class="orderFrame"]');
            const frame = await frameHandle.contentFrame();
            console.log('iFrame load succesfull')

            // paste ORG
            const OrgInput1 = "#Netui_Form_0 > table > tbody > tr:nth-child(4) > td > table > tbody > tr > td > table > tbody > tr:nth-child(3) > td:nth-child(2) > input[type=text]";
            await frame.waitForSelector(OrgInput1);
            await frame.type(OrgInput1, orgNumber, {delay:100});
            // click Next
            await frame.waitFor(2000);
