The frames in an html code are represented by the frames/iframe tag. Puppeteer can handle frames by switching from the main page to the frame. To work with elements inside a frame, first we have to identify the frame with the help of locators. The method contentFrame is used to access the elements inside the frame.
Syntax
The syntax to handle frames is as follows −
const f = await page.$("frame[name=''frame-bottom'']") const m = await f.contentFrame()
Let us see the html code of an element inside a frame and obtain the text – BOTTOM inside it.
The tagname highlighted in the above image is frame and the value of its name attribute is frame-bottom.
To begin, follow Steps 1 to 2 from the Chapter of Basic Test on Puppeteer which are as follows −
Step 1 − Create a new file within the directory where the node_modules folder is created (location where the Puppeteer and Puppeteer core have been installed).
The details on Puppeteer installation is discussed in the Chapter of Puppeteer Installation.
Right-click on the folder where the node_modules folder is created, then click on the New file button.
Step 2 − Enter a filename, say testcase1.js.
Step 3 − Add the below code within the testcase1.js file created.
//Puppeteer library const pt= require(''puppeteer'') async function frameHandle(){ //launch browser in headless mode const browser = await pt.launch() //browser new page const page = await browser.newPage() //launch URL await page.goto(''https://the-internet.herokuapp.com/nested_frames'') //identify frame const f = await page.$("frame[name=''frame-bottom'']") //move to frame const x = await f.contentFrame(); //identify element inside frame const n = await x.$("body") //get text const v = await (await n.getProperty("textContent")).jsonValue() console.log(v) } frameHandle()
Step 4 − Execute the code with the command −
node <filename>
So in our example, we shall run the command −
node testcase1.js
After the command has been successfully executed, the text within the frame – BOTTOM gets printed in the console.
