Imagine waiting for multiple selectors like this:
const element = await page.waitForSelector("div#test div#test2 div#test3 button, div#zest div#zest2 div#zest3 button")
How do I tell whether the first selector matched, or the second one? Do I need to $ twice and then compare the element?
You are using , separator which is the "multiple" operator.
To see which element you have, check the id of the parent.
const element = await page.waitForSelector("div#test div#test2 div#test3 button, div#zest div#zest2 div#zest3 button")
const parent = await element.$('xpath=..')
if (parent) {
const id = await parent.getAttribute('id')
console.log('id', id)
expect(id).to.eq('test3') // passes in test3 is present
// or if test3 is not present
expect(id).to.eq('zest3') // zest3 passes if test3 is not present
}
You can separate the selectors using a comma, which acts as an OR condition, and then extract the innerText of those elements. And then on the basis of the inner text, determine which selector was available.
const elementText = await page
.locator(
'div#test div#test2 div#test3 button,div#zest div#zest2 div#zest3 button'
)
.innerText()
if (elementText == 'some text') {
//Do something
}
In case you have an attribute-value pair that is unique to both, you can do like this:
const elementText = await page
.locator(
'div#test div#test2 div#test3 button,div#zest div#zest2 div#zest3 button'
)
.getAttribute('id')
if (elementText == 'zest') {
//Do something
}
There are several div classes "jadejhlu" containing a a=href link. How can I select only the first div class to get only one link? I tried
const selector = 'div.jadejhlu > a'
const links = await page.$$eval(selector, am => am.filter(e => e.href).map(e => e.href))
console.log(links)
like it is explained here: Puppeteer - Retrieving links from divs with specific class names
I get a list of links. I could also try to extract the first link of this list. Or I could try to insert a [0] to select only the first div.
Any ideas? Thanks in advance.
use $eval instead:
const selector = 'div.jadejhlu > a'
const links = await page.$eval(selector, (el) => el.href);
console.log(links)
You can use nth-child method to select the first element only.
Something like this:
const selector = 'div.jadejhlu > a:nth-child(1)'
I have a list of objects in my redux state. I am trying to filter them using a searchbox and dispatching an action on every change. My state does update when I type but doesn't go back (doesn't show all contents) when I delete. I believe that I'm modifying the state and so when search bar is empty again, there is nothing left to filter.
header.js
export const Header = () =>{
const locationsDropdown = useSelector(selectAllLocations);
const departmentsDropdown = useSelector(selectAllDepartments);
const employees = useSelector(selectAllEmployees)
const dispatch = useDispatch()
const [searchField, setSearchField] = useState("")
const handleChange = (e) => {
setSearchField(e.target.value)
dispatch(listFiltered(searchField))
console.log(employees)
}
snippet from employeeSlice.js (reducer action)
listFiltered:{
reducer(state, action) {
//filters the array but when search is deleted, items don't come back
return state.filter(item => item.fname.includes(action.payload))
}
}
If I try to use this function in header.js (where search field is located), everything works well.
const filtered = employees.filter(item => {
const itemName = item.fname
return itemName.includes(searchField)
})
Problem is that header.js component is not responsible for rendering items where needed and I don't how (if possible) to export 'filtered' result to other components
Is there any method (didn't find in API) or solution to click on element with text?
For example I have html:
<div class="elements">
<button>Button text</button>
<a href=#>Href text</a>
<div>Div text</div>
</div>
And I want to click on element in which text is wrapped (click on button inside .elements), like:
Page.click('Button text', '.elements')
Short answer
This XPath expression will query a button which contains the text "Button text":
const [button] = await page.$x("//button[contains(., 'Button text')]");
if (button) {
await button.click();
}
To also respect the <div class="elements"> surrounding the buttons, use the following code:
const [button] = await page.$x("//div[#class='elements']/button[contains(., 'Button text')]");
Explanation
To explain why using the text node (text()) is wrong in some cases, let's look at an example:
<div>
<button>Start End</button>
<button>Start <em>Middle</em> End</button>
</div>
First, let's check the results when using contains(text(), 'Text'):
//button[contains(text(), 'Start')] will return both two nodes (as expected)
//button[contains(text(), 'End')] will only return one nodes (the first) as text() returns a list with two texts (Start and End), but contains will only check the first one
//button[contains(text(), 'Middle')] will return no results as text() does not include the text of child nodes
Here are the XPath expressions for contains(., 'Text'), which works on the element itself including its child nodes:
//button[contains(., 'Start')] will return both two buttons
//button[contains(., 'End')] will again return both two buttons
//button[contains(., 'Middle')] will return one (the last button)
So in most cases, it makes more sense to use the . instead of text() in an XPath expression.
You may use a XPath selector with page.$x(expression):
const linkHandlers = await page.$x("//a[contains(text(), 'Some text')]");
if (linkHandlers.length > 0) {
await linkHandlers[0].click();
} else {
throw new Error("Link not found");
}
Check out clickByText in this gist for a complete example. It takes care of escaping quotes, which is a bit tricky with XPath expressions.
You can also use page.evaluate() to click elements obtained from document.querySelectorAll() that have been filtered by text content:
await page.evaluate(() => {
[...document.querySelectorAll('.elements button')].find(element => element.textContent === 'Button text').click();
});
Alternatively, you can use page.evaluate() to click an element based on its text content using document.evaluate() and a corresponding XPath expression:
await page.evaluate(() => {
const xpath = '//*[#class="elements"]//button[contains(text(), "Button text")]';
const result = document.evaluate(xpath, document, null, XPathResult.ANY_TYPE, null);
result.iterateNext().click();
});
made quick solution to be able to use advanced css selectors like ":contains(text)"
so using this library you can just
const select = require ('puppeteer-select');
const element = await select(page).getElement('button:contains(Button text)');
await element.click()
The solution is
(await page.$$eval(selector, a => a
.filter(a => a.textContent === 'target text')
))[0].click()
Here is my solution:
let selector = 'a';
await page.$$eval(selector, anchors => {
anchors.map(anchor => {
if(anchor.textContent == 'target text') {
anchor.click();
return
}
})
});
There is no supported css selector syntax for text selector or a combinator option, my work around for this would be:
await page.$$eval('selector', selectorMatched => {
for(i in selectorMatched)
if(selectorMatched[i].textContent === 'text string'){
selectorMatched[i].click();
break;//Remove this line (break statement) if you want to click on all matched elements otherwise the first element only is clicked
}
});
Since OP's use case appears to be an exact match on the target string "Button text", <button>Button text</button>, text() seems like the correct method rather than the less-precise contains().
Although Thomas makes a good argument for contains when there are sub-elements, avoiding false negatives, using text() avoids a false positive when the button is, say, <button>Button text and more stuff</button>, which seems just as likely a scenario. It's useful to have both tools on hand so you can pick the more appropriate one on a case-by-case basis.
const xp = '//*[#class="elements"]//button[text()="Button text"]';
const [el] = await page.$x(xp);
await el?.click();
Note that many other answers missed the .elements parent class requirement.
Another XPath function is [normalize-space()="Button text"] which "strips leading and trailing white-space from a string, replaces sequences of whitespace characters by a single space" and may be useful for certain cases.
Also, it's often handy to use waitForXPath which waits for, then returns, the element matching the XPath or throws if it's not found within the specified timeout:
const xp = '//*[#class="elements"]//button[text()="Button text"]';
const el = await page.waitForXPath(xp);
await el.click();
With puppeteer 12.0.1, the following works for me:
await page.click("input[value='Opt1']"); //where value is an attribute of the element input
await page.waitForTimeout(1000);
await page.click("li[value='Nested choice 1']"); //where value is an attribute of the element li after clicking the previous option
await page.waitForTimeout(5000);
I had to:
await this.page.$eval(this.menuSelector, elem => elem.click());
You can just use the query selector.
await page.evaluate(() => {
document.querySelector('input[type=button]').click();
});
Edits ----
You can give your button a className and use that to select the button element since you know exactly what you're trying to click:
await page.evaluate(() => {
document.querySelector('.button]').click();
});
I want to test if an element had been rendered. So I want expect that if is present. Is there a command for this?
await page.goto(‘<http://localhost:3000/>');
const logo = await page.$(‘.logo’)
// expect(logo.toBeInDocument())
If you query one element with page.$(), you can simply use:
const logo = await page.$('.logo');
if (logo) {
}
Similarly if you query multiple elements with page.$$():
const logo = await page.$$('.logo');
if (logo) {
}
Since this example returns (after awaiting) an array of element handles, you can also use property length in the condition:
const logo = await page.$$('.logo');
if (logo.length) {
}
The key in all these examples is to await the promise that page.$() and page.$$() return.
Since the use of ElementHandle (page.$(), page.$$()) is discouraged by the Playwright Team, you could use the Locator object and the count() method:
expect(await page.locator('data-testid=exists').count()).toBeTruthy();
expect(await page.locator('data-testid=doesnt-exist').count()).toBeFalsy();
If you want to check if the element is rendered (I assume you mean visible) you could use the toBeVisible assertion:
await expect(page.locator('data-testid=is-visible')).toBeVisible();
