How to find, replace and write text in to the text field by xpath-javascript?



Text-field with elements



HTML



This is my first question here. Any suggestions to improve are helpful.



I have added two images. First image shows that text-field/box along with HTML elements. I need to get the value "www.google.com/abc" and replace abc with xyz and write back to the same text-box.


www.google.com/abc


abc


xyz



1) I am able to do this, when element has unique attributes like ID, ClassName as below


unique


like ID, ClassName


var tmp1 = (document.getElementById('properties.landingPageUrl').value.toLowerCase()).replace('abc','xyz');
document.getElementById("properties.landingPageUrl").value=tmp1;



2) In the attached first image,<input type="text" autocomplete="off" class="a-input-text a-width-extra-large" value="" data-reactid=".0.5.2.0.1.4.1.0.0:$0.1.0.0:$/=10"> has ClassName a-input-text a-width-extra-large , which is not identical. For another text box also, it shows same ClassName. So, to make it unique used xpath: //span[contains(text(),"Third party click tracking URL")]/../../../div[2]//input , which points to a particular text-box (for field 'Third party click tracking URL').


<input type="text" autocomplete="off" class="a-input-text a-width-extra-large" value="" data-reactid=".0.5.2.0.1.4.1.0.0:$0.1.0.0:$/=10">


ClassName


a-input-text a-width-extra-large


xpath: //span[contains(text(),"Third party click tracking URL")]/../../../div[2]//input


How can i get the value from text-box and replace by some pattern and write back to the text-box (`in the second instance`) ?



I tried document.EelementByXpath, but not working


document.EelementByXpath


ERROR

Uncaught TypeError: document.getElementByXpath is not a function

eventHandle @ userscript.html?id=935b3faf-380a-4fa1-ba80-e2a14b01fe91:2944



So, is there any method which can be used for xpaths or any other way to achieve the second instance ?





Welcome! Error messages matter. Copy / paste the exact message into your question, please.

@cale_b Thank you. Can I do the same for xpath ? since document.getElementByXpath doesn't work, should document.evaluate to be used ? I'm not sure.

@Jackie: Help us help you by providing the exact error message as cale_b requested. You should also provide a Minimal, Complete, and Verifiable example. Thank you.

Why have you still not posted your error message? Also, your "MCVE" is neither complete nor verifiable. Moving on. Good luck.

The code you have shown cannot give the error message you claim. So, not only is that not an MCVE, it's not coherent either. In addition this is an obvious "XY Problem". Link to the target page and describe what your desired result is (hint: it has nothing to do with XPath).

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Dynamically update html content plain JS

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
