const toggleInfo = (index, event) => { setVisibleLightIndexes((prev) => { if (prev.includes(index)) { return prev.filter((i) => i !== index); } else { return [...prev, index]; } }); const clickedElement = event.target.closest(".chauvetLights"); if (clickedElement) { clickedElement.classList.toggle("expanded"); } toggleBackgroundColor(event); }; TypeError: Cannot read properties of undefined (reading 'target') at k (home-OO3WpeNb.js:1:102576) at onClick (home-OO3WpeNb.js:1:104620) at Object.Em (index-h-qGlws7.js:38:9852) at km (index-h-qGlws7.js:38:10006) at Cm (index-h-qGlws7.js:38:10063) at Wa (index-h-qGlws7.js:38:31422) at fd (index-h-qGlws7.js:38:31839) at index-h-qGlws7.js:38:36751 at Vs (index-h-qGlws7.js:41:36768) at Df (index-h-qGlws7.js:38:8988)
The error message "TypeError: Cannot read properties of undefined (reading 'target')" means that the code is trying to access the target
property of an undefined value. In this case, it seems that the event
parameter passed to the toggleInfo
function is undefined or null.
To resolve this error, you need to make sure that the event
parameter is being properly passed to the toggleInfo
function. Check where the toggleInfo
function is being called and ensure that the event object is being passed correctly.
It's also possible that the error is occurring because the event listener is not properly set up for the element triggering the event. Double-check that the event listener is assigned to the correct element and that it is triggered as expected.
Without more context or the full code, it's difficult to provide a more specific solution. If you can provide more information or share more of the code, I can try to help you further troubleshoot the issue.
what is target in <a>
In the context of HTML, the target
attribute is used in the <a>
(anchor) tag to specify how the linked URL should be opened.
Here's an example:
code Copy code
<a href="https://www.example.com" target="_blank">Link</a>
In this example, the target
attribute is set to _blank
, which tells the browser to open the linked URL in a new tab or window.
Other possible values for the target
attribute include:
_self
: Opens the linked URL in the same window/tab._parent
: Opens the linked URL in the parent window/tab (used in framesets)._top
: Opens the linked URL in the full body of the window/tab (used in framesets).Please note that the target
attribute is optional and if it is not specified, the linked URL will open in the same window/tab by default.
what is target on html?

How can I target an object key on an alert?
You can target an object key in an alert box by using the object name followed by the key name in square brackets. Here's an example:
javascript Copy code
let person = {
name: 'John',
age: 30
};
// Targeting object key in alert box
alert(person['name']); // will display 'John'
You can also use dot notation to access the object key instead of square bracket notation:
javascript Copy code
let person = {
name: 'John',
age: 30
};
// Targeting object key in alert box using dot notation
alert(person.age); // will display 30
what do we use the target for in React?
In React, we use the target
attribute to define the target window or frame that is going to be used after submitting a form. This is commonly used when creating a link that should open in a new tab or when submitting a form that should open in a new window.
For example, if you want a link to open in a new tab, you can use the target='_blank'
attribute.
html Copy code
<a href="https://www.shecodes.io" target="_blank">Visit SheCodes</a>
Here, the link will open in a new tab when clicked.
how to make a new tab when clicking on a link

To make the link red, you can use CSS to style the anchor tag. Set the color property to red in your CSS file or by adding a style attribute to the anchor tag.
html Copy code
<a href="https://www.example.com" target="_blank" style="color: red;">Link Text</a>
This code will create a red link that will open "https://www.example.com" in a new browser window or tab when clicked. Note that this changes the color of the link text, not the color of the new window that opens.
Can I have multiple id selectors to target it in my Javascript
Yes, you can have multiple ID selectors to target an element in Javascript. You can use the querySelectorAll() method to select multiple ids like this:
js Copy code
const elements = document.querySelectorAll('#id1, #id2, #id3');
what is target in javascript?
In JavaScript, the target
property of a Event
object identifies the element that initiated an event. When a certain event is triggered on a certain element, the target
property of the Event
object is set to that element. This property can be used to tell the origin of the event.
For example:
javascript Copy code
<h1 onclick ="alertEvent(event)">
Click me
</h1>
<script>
function alertEvent(e){
alert(e.target.innerHTML);
}
</script>
In the above example, when the h1
is clicked, the onclick
event will be triggered. As a result, the alertEvent()
function will be called and the target
property will be set to h1
, allowing you to use the e.target.innerHTML
statement to retrieve the text of the h1
, that is, "Click me".

Not likely. AI can automate tasks and make developers' jobs more efficient but it can't fully replace the human ability to deal with complex software. And AI will still require human developers to supervise and improve it further.
So developers may see their tasks change but they won't be replaced by AI. 👩💻🤝💻
