I am selecting options from select -> option
, and each time page reloads, first when I click the dropdown, I collect all elementHandles that I want to select. I want to go through all of them.
I can only select the first one and then I get this error:
JSHandles can be evaluated only in the context they were created
So I am trying to recreate ElementHandles each time page reloads. I have this code:
Function 1:
case:click
try {
await page.evaluate((el) => {
return el.click()
}, 'select');
await page.waitFor(1500);
} catch (e) {
console.log(e);
}
break;
case: getNavigation
let navigation = await page.$$('select > option');
break;
case: doActions
let i = 0;
for (elements in navigation) {
let result = await function2(commands, i, page)
i++;
}
break;
Then Function 2:
async function function2(commands, i, inPage){
let page = inPage;
if (!page) {
const browser = await puppeteerLambda.getBrowser({ headless: true, slowMo: 100, args: ['--no-sandbox', '--disable-setuid-sandbox', '--single-process', '--start-fullscreen', '--window-size=1413,749']}); //TODO: setup Proxy
console.log('opening new page');
page = await browser.newPage();
....
}
let navigation;
case: click
try {
await page.evaluate((el) => {
return el.click()
}, 'select');
await page.waitFor(1500);
} catch (e) {
console.log(e);
}
case: getNavigation
navigation = await page.$$('select > option'); //recreating elementHandle array
case: selectOption
const optionValue = await page.evaluate(value => value.value, navigation[i]);
await page.select('select', optionValue);
case: extract
......
Again I get to select options 2 times and then I get this error:
Error: Protocol error (Runtime.callFunctionOn): Cannot find context with specified id
Can anyone help me how to handle this?
Represents a reference to a JavaScript object. Instances can be created using Page. evaluateHandle(). Handles prevent the referenced JavaScript object from being garbage-collected unless the handle is purposely disposed.
JSHandle represents an in-page JavaScript object. JSHandles can be created with the page. evaluateHandle method. var windowHandle = await page.
JSHandle@node means an element handle. Also, refer to the typescript types https://github.com/puppeteer/puppeteer/blob/main/src/common/Page.ts#L1075. All reactions.
According to the Official Documentation for JSHandle
:
JSHandles are auto-disposed when their origin frame gets navigated or the parent context gets destroyed.
Therefore, every time the page reloads, you will need to reobtain the JSHandle
