I'm working on an electron application where I want to start a child node process (to run a Discord.JS bot).
I have the following code:
index.html:
<tr>
<th class="title-bar-cell" style="text-align: left;">
<i onclick="window.close()" id="close-button" class="far fa-window-close"></i>
<i onclick="ipcRenderer.send('minimize')" id="minimize-button" class="far fa-window-minimize"></i>
<p id="title-bar-text">Toggle Control Panel</p>
</th>
<th class="title-bar-cell right-indent" style="text-align: right;">
<i id="new-bot-button" class="fas fa-plus bar-icon"></i>
<i id="select-bot-button" class="fas fa-box-open bar-icon"></i>
<i id="start-bot-button" class="fas fa-play bar-icon"></i>
<i id="stop-bot-button" class="fas fa-stop bar-icon"></i>
<i id="about-button" class="fas fa-info bar-icon"></i>
</th>
</tr>
botController.js:
document.getElementById('start-bot-button').addEventListener('click', () => {
ipcRenderer.send('startBot');
})
However, JavaScript is throwing an error saying that I can't add the attribute addEventListener to null. Why?
Also, do I need to import something for ipcRenderer? Or is it just given.
Where in the HTML are you loading botController.js? If you're loading it in the <head> tag, remove it and put it at the bottom of your HTML body (inside the tag). It may be returning null because the DOM has not loaded yet.
Also to use ipcRenderer, add the following line to the top of botController.js:
const { ipcRenderer } = require('electron');

I'm trying to use Font Awsome in my web poject,
I've added the link:
<script src="https://use.fontawesome.com/bedf006dec.js"></script>
When I add font awesome directly to my HTML like this:
<div class="topbar">
<div class="topbar__elements container">
<div class="topbar__left">
<a href="#">
<i class="fa fa-map-marker" aria-hidden="true"></i>
<span> Middle East Airlines Ground Handling</span>
</a>
<a href="mailto:meag#meag.com.lb" target="_top" rel="noopener noreferrer">
<i class="fa fa-envelope" aria-hidden="true"></i>
<span> meag#meag.com.lb</span>
</a>
<a href="tel:00961 1 622700">
<i class="fa fa-phone" aria-hidden="true"></i>
<span> +961 1 622700</span>
</a>
</div>
<div class="topbar__right">

It works fine:
I'm also using tiny slider and I want to change the text of the previous and next buttons to have Font Awsome icons, I know that I can create custom buttons with tiny slider directly in the HTML code but I'm trying to use the default controls of tiny slider, therefore to try and change the text of these 2 buttons I'm using javascript:
const prevBtn = document.querySelector(".tns-controls").firstChild;
const nextBtn = document.querySelector(".tns-controls").lastChild;
prevBtn.innerHTML = "<i class='fa-solid fa-angle-left' aria-hidden='true'></i>";
nextBtn.innerHTML = '<i class="fa-solid fa-angle-right" aria-hidden="true"></i>';
But it doesn't work and give me this:
Even though when I open the developer tools it looks like as if it worked.
A demo of my dilemma here
Let's say I have the following html:
<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<link href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">
<body>
<div class="main" id="thingSection">
<h1>
Test Header
</h1>
<button class="btn-icon"><i class="fa fa-fw fa-lg fa-windows"></i> <i class="fa fa-fw fa-lg fa-toggle-off"></i> <i class="fa fa-fw fa-lg fa-apple"></i></button>
<div class="content" id="content1">
Some content
</div>
</div>
<hr />
<div class="main" id="thingSection1">
<h1>
Another Test
</h1>
<button class="btn-icon"><i class="fa fa-fw fa-lg fa-windows"></i> <i class="fa fa-fw fa-lg fa-toggle-off"></i> <i class="fa fa-fw fa-lg fa-apple"></i></button>
<div class="content" id="content2">
Some content
</div>
</div>
<hr>
<div class="main" id="thingSection2">
<h1>
Another test, you say?
</h1>
<button class="btn-icon"><i class="fa fa-fw fa-lg fa-windows"></i> <i class="fa fa-fw fa-lg fa-toggle-off"></i> <i class="fa fa-fw fa-lg fa-apple"></i></button>
<div class="content" id="content3">
Some content
</div>
</div>
</body>
</html>
I am using the following jquery to change the toggle icon from FontAwesome from off to on:
$(function() {
$('.btn-icon').click(function() {
if ($(this).find($(".fa")).hasClass('fa-toggle-off')) {
$("i.fa-toggle-off").toggleClass('fa-toggle-on');
} else {
$("i.fa-toggle-on").toggleClass('fa-toggle-off');
}
});
});
When I click the button to toggle the icon, it works as expected, i.e. it changes all of the buttons on the page. However, I would like to dynamically determine which button has been pressed, and then change the content of a child div based on the position of the switch.
I want to avoid hardcoding id's for each button to avoid a ton of if/else statements in the script that must be updated each time I, say, add a new button or a new section. That is to say, I want to dynamically detect which button has been pressed, and affect only that button and its children.
I've noticed that console.log(this) yields only the HTML for the particular button that has been pressed, not all of the buttons.
I'm a novice with jquery. I haven't been able to find a solution to this problem yet, and I feel like there has to be a way to do this dynamically without hardcoding IDs.
EDIT: I've accomplished (partially) what I want to do with the following code:
$(function() {
$('.btn-icon').click(function() {
var t = $(this).find('.is-toggle');
if (t.hasClass('fa-toggle-off')) {
t.addClass('fa-toggle-on');
t.removeClass('fa-toggle-off');
}
else {
t.addClass('fa-toggle-off');
t.removeClass('fa-toggle-on');
}
});
});
Looks like I just didn't understand what exactly $(this) was (:
All you need is $(this) that selects the element that triggered the event. From there you can select down to the div you want.
EDIT: Here is how that might look in code, I pulled this from your fiddle and edited it
$(function() {
$('.btn-icon').click(function() {
$(this).children('.fa-toggle-off, .fa-toggle-on').toggleClass('fa-toggle-on fa-toggle-off');
});
});
Problem:
I am writing a tracking electron app where the user data is stored on a local JSON file. Essentially i have the cards (user info from json) loaded to display via html. My next step is to run the python backend, problem i am having is I currently can't load the correct array value, only the last one is currently loading into a variable that im trying to pass to python. Since im using forEach i shouldn't have to count or do i still need to do that?
What I expect to happen:
I want an alert to pop up with the current user.handle value. What happens now is it only pops up the last value in the array regardless of which card i press. How can i make each button press trigger the corresponding handle value?
When i test and swap out onclick="myFunction11()" with onclick=alert('${user.handle}') it prints the correct handle value. So i can assume i am just overwriting var city every time and left with the last one in the array. Any advice on how to correctly have myFunction11 pull the corresponding handle value i would love. thanks
Question:
How can i correctly have myFunction11 pull the correct handle value from the array? or is there a better way to achieve this?
Code:
$(document).ready(function() {
users.forEach(function(user) {
$('.team').append(`<div class="card">
<figure>
<img src="${user.image}" />
<figcaption>
<h4>${user.name}</h4>
<h5>${user.handle}</h5>
</figcaption>
</figure>
<div class="links">
<i class="fa fa-pencil"></i>
<i class="fa fa-truck"></i>
<i class="fa fa-trash-o"></i>
</div>
<div class="task">
<div>
</div>
</div>
<div class="bottom-links">
<i class="fa fa-pencil"></i> EDIT
<i class="fa fa-truck"></i> TRACK
</div>
</div>
<script>
function myFunction11() {
var city = '${user.handle}';
alert(city);
}
</script>
`);
});
Adding duplicates of the same function is indeed bad practice. Your way when you have three users you will have defined function myFunction11 three times. And in fact (as you guessed) you end up with the function only having the last value of city.
Instead, this should be better:
$(document).ready(function() {
$('.team').append(`<script>
function myFunction11(city) {
alert(city);
}
</script>`);
users.forEach(function(user) {
$('.team').append(`
...
<i class="fa fa-pencil"></i>
...`);
});
define function outside loop and pass user index as parameter
function myFunction11(index) {
var city = users[index].handle;
alert(city);
}
$(document).ready(function() {
users.forEach(function(user,i) {
$('.team').append(`<div class="card">
<figure>
<img src="${user.image}" />
<figcaption>
<h4>${user.name}</h4>
<h5>${user.handle}</h5>
</figcaption>
</figure>
<div class="links">
<i class="fa fa-pencil"></i>
<i class="fa fa-truck"></i>
<i class="fa fa-trash-o"></i>
</div>
<div class="task">
<div>
</div>
</div>
<div class="bottom-links">
<i class="fa fa-pencil"></i> EDIT
<i class="fa fa-truck"></i> TRACK
</div>
</div>`);
});
});
HTML of that part is:
<div class="review-small-text">
<span class="stars-rate">
<span property="starsRating">
<i class="fa fa-star-yellow fa-star"></i>
<i class="fa fa-star-yellow fa-star"></i>
<i class="fa fa-star-yellow fa-star"></i>
<i class="fa fa-star-yellow fa-star"></i>
<i class="fa fa-star-yellow fa-star"></i>
</span>
</span>
<span property="reviewRating" typeof="Rating" style="display:none;">
<span property="ratingValue">5</span>
<span property="bestRating">5</span>
<span property="worstRating">0</span>
</span>
<span property="itemReviewed" typeof="Service" class="">Liposuction</span> </div>
I'm trying to extract the second span's ratingValue of a particular review using selenium and i tried to extract that value by using this css selector:
'div.review-small-text>span:nth-of-type(2)>span:nth-of-type(1)'
but it is giving me an empty string.
have also tried this one
'div.review-small-text>span:nth-child(2)>span:nth-child(1)'
so I think the problem is not in the css-selector. Display none is creating an issue here.
Is there any possible way to extract that value?
Python source code that i have tried so far is:
from selenium import webdriver
import time
url = "myurlhere"
driver = webdriver.Chrome()
driver.get(url)
time.sleep(3)
all_reviews_listings = driver.find_elements_by_xpath("//div[#id='tab_reviews']/div[#class='provider_all_Reviews']/div[#id='pnlReviews']/div")
for review in all_reviews_listings:
review_rating = review.find_element_by_css_selector('div.review-small-text>span:nth-of-type(2)>span:nth-of-type(1)').text
print("Review Rating: ", review_rating)
Here is the css to get the ratingValue.
Using JavaScript:
review_rating = driver.execute_script("""return document.querySelector(".review-small-text > span[property='reviewRating'] > span[property='ratingValue']").textContent""")
Without JavaScript: Alternatively you can also do this.
driver.find_element_by_css_selector(".review-small-text > span:nth-child(2) > span[property='ratingValue']").get_attribute("textContent")
The ancestor tag is having the attribute style="display:none;, so to extract all the reviewRatings you can use the following solution:
driver.execute_script("arguments[0].removeAttribute('style')", driver.find_element_by_css_selector("div.review-small-text span[property='reviewRating'][typeof='Rating']"))
print([element.text for element in driver.find_elements_css_selector("div.review-small-text span[property='reviewRating'][typeof='Rating'] span")])
I have slide out navigation on my page which is loaded automatically i.e. on the page load.I want that it should only open when user clicks on the menu bar(in my case it's hamburger sign).
Html code:
<i class="fa fa-bars toggle_menu"></i>
<div class="sidebar_menu">
<i class="fa fa-times"></i>
js code:
$(document).ready(function() {
$(".fa-times").click(function() {
$(".sidebar_menu").addClass("hide_menu");
$(".toggle_menu").addClass("opacity_one");
});
$(".toggle_menu").click(function() {
$(".sidebar_menu").removeClass("hide_menu");
$(".toggle_menu").removeClass("opacity_one");
});
});
I believe you need to add class hide_menu in your HTML itself so that the sidebar_menu will be hidden at the time of page load. So modify HTML like:
<i class="fa fa-bars toggle_menu"></i>
<div class="sidebar_menu hide_menu">
<i class="fa fa-times"></i>
