I'm trying to use 2Captcha service to solve an h captcha V2.
Works like this:
you get a value to solve the captcha
Then you find a textarea element in the HTML code to insert that value (here's my problem)
you insert the value in that element
You press submit button and the captcha is solved
First I'm going to present a working example, then I'll present where I have the problem.
This is the HTML code to find and insert the obtained value:
textarea id="h-captcha-response" name="h-captcha-response" style="display: none;"></textarea>
This is the python code used to insert the value:
value = get_value()
insert_solution = 'document.getElementById("h-captcha-response").innerHTML="' + value + '";'
driver.execute_script(insert_solution)
What this exactly does is taking you from this:
and this is the result:
Finally you press the submit button and it's done. This example works
This is my problem:
In my case the HTML document has a variable ID, like this one:
<textarea id="h-captcha-response-0tesbrpxsk8" name="h-captcha-response" style="display: none;"></textarea>
Notice that the id has an alphanumerical part (0tesbrpxsk8) that always changes making it more difficult to select.
I tried to find some regular expression to use inside of document.getElementById()
With no success
I also tried to use:
document.getElementByTagName("textarea").innerHTML=".....
I'm stucked here and tried other approaches with no success because I probably because I don't implement well those solutions or they just don't work.
I'll appreciate some insights, thanks
This will fill out all of those (recaptcha / hcaptcha):
driver.execute_script('''
let [captcha] = arguments
[...document.querySelectorAll('[name="h-captcha-response"],[name="g-recaptcha-response"]')].map(el => {
el.innerHTML = captcha
})
''', value)
Try this:
const textarea = document.querySelector('[id^="h-captcha-response-"]')
textarea.value = "This is inside the textarea!"
<textarea id="h-captcha-response-0tesbrpxsk8" name="h-captcha-response"></textarea>
First of all: You set the value of an textarea with textarea.value = "some value"
You should use document.querySelector() to select elements. (You have much more abilities there)
You can select id starting with, with this query: [id^="start"]

I'm trying to change the value of an element on a third-party web page using a JavaScript Add-on to display a hyperlink
I already have the link on the page i would like to be able to click it
I think I'm on the right track using document.getElementById although I'm not sure how to then change the id into a "a href" and then how to pass it back into the value.
Sorry, this is a bit of a tricky situation so I'll try my best to explain it. On a third-party web-page which we use for our HR related tasks, there is a section titled "File Link" although this isn't a link. When you copy and paste the address into a browser it displays the file. What i am trying to do is create a hyperlink on the "File Link" section to remove the need to copy and paste the link. Because this is a third party website. We have access to the JavaScript on the website and need to change the address into a hyperlink. I'm not entirely sure this is possible.The element id is "__C_cb_file_link" and i would like to insert the link address into the element using a variable then add the link parameters into the variable then reinsert it into the element/value.
function linkIt() {
var intoLink = document.getElementById("__C_cb_file_link");
var hLink = "<a href="+intoLink+"</a>;
intoLink.value = hLink;
}
window.onload = linkIt();
<td><div class="sui-disabled" title="">m-files://view/37FF751C-A23F-4233-BD8B-243834E67731/0-46524?object=C46A7624-D24B-45F3-A301-5117EFC1F674</div>
<input type="hidden" name="__C_cb_file_link" id="__C_cb_file_link" value="m-files://view/37FF751C-A23F-4233-BD8B-243834E67731/0-46524?object=C46A7624-D24B-45F3-A301-5117EFC1F674"/></td></tr>
In below code first we read input value with new link (however we can read this value from other html tags), then we remove this element (and button) and add to parent element (of removed input) the new link
function linkIt() {
let intoLink = __C_cb_file_link.value;
let parent = __C_cb_file_link.parentNode;
__C_cb_file_link.remove();
btn.remove();
parent.innerHTML += `${intoLink}`;
}
<input id="__C_cb_file_link" value="https://example.com">
<button id="btn" onclick="linkIt()">Link It</button>
There are a number of issues with your code:
1) The code snippet in your question doesn't run because of a missing " at the end of the second line of the linkIt() function.
2) intoLink is a hidden field so anything you add to it will not be visible in the page
3) Even if point 2 were not true, setting the value of a form field will not cause HTML to appear on the page (at best you might get some plain text in a textbox).
4) "<a href="+intoLink+"</a>" doesn't work because intoLink is a complex object which represents the entire hidden field element (not just its value property). You can't convert a whole object into a string directly. You need to extract the value of the field.
A better way to do this is by creating a new element for the hyperlink and appending it to the page in a suitable place. Also I recommend not adding your event via onload - when written using this syntax only one onload event can exist in a page at once. Since you're amending another page which isn't under your control you don't want to disable any other load events which might be defined. Use addEventListener instead, which allows multiple handlers to be specified for the same event.
Demo:
function linkIt() {
var intoLink = document.getElementById("__C_cb_file_link");
var hLink = document.createElement("a");
hLink.setAttribute("href", intoLink.value);
hLink.innerHTML = "Click here";
intoLink.insertAdjacentElement('beforebegin', hLink);
}
window.addEventListener('load', linkIt);
<td>
<div class="sui-disabled" title="">m-files://view/37FF751C-A23F-4233-BD8B-243834E67731/0-46524?object=C46A7624-D24B-45F3-A301-5117EFC1F674</div>
<input type="hidden" name="__C_cb_file_link" id="__C_cb_file_link" value="m-files://view/37FF751C-A23F-4233-BD8B-243834E67731/0-46524?object=C46A7624-D24B-45F3-A301-5117EFC1F674" /></td>
</tr>
P.S. m-files:// is not a standard protocol in most browsers, unless some kind of extension has been installed, so even when you turn it into a hyperlink it may not work for everyone.
[UPDATE] I supose that your "__C_cb_file_link" was a paragraph so I get the previous text http://mylink.com and create a link with, is it what you want, right?
function linkIt() {
let fileLink = document.getElementById("__C_cb_file_link");
let hLink = fileLink.textContent;
fileLink.innerHTML = ""+hLink+"";
}
linkIt();
<div>
<p id="__C_cb_file_link">http://myLink.com</p>
</div>
Its probably something basic but wanted explanation of the use cases. Like sometimes hitting "enter" inputs the data, while sometimes mouseclicks work. I'm concerned about "Gotchas" that I would have overlooked. Like maybe it works in Firefox but not in Chrome for example.
I saw the following 2 ways, both are ways to input data into a form element.
First way
JavaScript
var $body = $(e.target).find('[name=body]'); //defines the content
var comment = { body: $body.val() };
HTML
<form class="form-send-message" id="addcomment" data-keyboard-attach>
<textarea id="body" name="body"></textarea>
</form>
Second way
JavaScript
var message = template.find('input').value;
HTML
<form class="message" data-keyboard-attach>
<input type="text" name="body" id="body">
<button class="icon" type="submit"></button>
</form>
Here you can see two ways to find the value of an input/textarea with an explanation:
'submit .new-post': function(event){
//returns name="postBody" content from the form you're submitting
var postBody = event.target.postBody.value;
//returns the value of an html element that exists in DOM, even if its inside a different template or form.
var postBody = $('.someClass').val()
}
Your first code Is jQuery, while your second code is Meteor. They both can accomplish the same thing under the right circumstances. Also, according to this answer, meteor's template.find is an alias for jQuery's $, meaning they are the exact same.
But, the codes don't do the same thing in this case.
Your first code finds the value an element with a name of "body" inside e.target. I am assuming e is an Event, but there is no way to tell with the current amount of code you gave.
The second code just gets the value of the first INPUT element it finds.
So, I got the page on my local server, and this page contains textarea and button. I am Trying to write onclick function to button, which would read whatever I typed in text area, and make record to database. Just like when I finish typing my question here, and press Ask Question. The problem is that I can't properly read text in text area, it basically sees only what was in there at the moment of loading a page, and just rewrite it. How should I get text, that I typed right before clicking the button? I just want to know how can I copy that text to some var, which I can PUT to database.
$.getJSON('/link/' + tenderId, function (data) {
var description = '';
description += '<textarea id="description" class="form-control" rows="3">' + data.description + '</textarea>';
$('#description').html(description);
});
Use this code inside your click event
var textareaValue = $('textarea#textareaId').val();
html
<textarea id="textareaId"></textarea>
SO answer: https://stackoverflow.com/a/144836/2772017
You need to use val() (I am guessing you are using text()) to get the text of a Text Area:
$('input#mybutton').click(function() {
var text = $('textarea#mytextarea').val();
});
Of course this is just guesswork as you did not supply any code! :)
Update:
The code you added is also incorrect as it adds a duplicate id of description inside a div with an id of description! ID's need to be unique on a page.
Assuming you want a new id here is a cleaner version of your code:
$.getJSON('/link/' + tenderId, function (data) {
var $textArea = $("<textarea>", {class: "form-control", id: "descriptionText", rows: "3"}).val(data.description);
$('#description').empty().append(description);
});
I can't figure out you method logic; it seems you are pulling some json data then appending it to a textarea while in issue description you said that you are trying to save the textarea content so you have to be sending it throug a POST request.
Also does the <textarea id="description"...> element is there in your page or you will be creating it at each button click?
If such is you case, you can try with the following snippet:
$.getJSON('/link/' + tenderId, function (data) {
var $description = $("<textarea>");
$description.attr({
id:'description',
class:'form-control',
rows:'3'})
.html(data.description);
//you will have then to append this jQuery element, e.g: $("#wrapper").append($description)
});
$('button').click(function(){
var myString = $('#description').val();
})
Then use myString whereever you like.
Check input tag which have value only as <br/> tag inside as value using jQuery
I am using an htmlEditor in my project, sometimes user just press enter key only in textarea field. It will get as <br/><br/><br/><br/> as value when saving.
I want to avoid this tags when saving.
How to validate this in jquery ?
If any other characters like <br/>Just <br/> Example <br/> is present then I want to save it with break tag itself.
using a regex like this would help.
/^(\<br\/>)+$/.test($("textarea").val());
Clean it like this:
// Get the HTML and remove <br /> variants
var htmlCleaned = $('#MyTextArea').val().replace(/<br\s?\/?>/, '');
Refer LIVE DEMO
var divTag = $("div");
var nDivTag = $(divTag[0].outerHTML);
$("br", nDivTag).remove();
alert(nDivTag.html());
I would like to change the value of a textarea when hovering over a link. I am not very proficient at javascript and do not quite understand the intricacies of 'this.' and 'document.' etc..
Currently I have a textarea 'info' that on page load is unpopulated and two links that should change its value. I can not seem to get it to work..
<textarea name="info"></textarea>
Foo.com
Bar.com
I'm sure there is a way to accomplish what I need to do but I can't find it.
Thanks in advance.
Create a function, that accepts the string you want, and sets the textarea:
// Select the textarea by its ID (that you need to give it)
var textarea = document.getElementById('info');
// Define the function that sets the value passed
function changeTextarea( str ) {
textarea.value = str;
}
Assign an ID to the textarea, and call the function in the onmouseover, passing the string you want to set:
<textarea name="info" id='info'></textarea>
Foo.com
Bar.com
