FAQs on jQuery Tutorial - 31 - Click Video Lecture - Importance of jQuery in Website Development - IT & Software
| 1. What is jQuery and why is it important for web development? |  |
Ans. jQuery is a fast, small, and feature-rich JavaScript library that simplifies HTML document traversal, event handling, animating, and Ajax interactions for web development. It is important for web development because it allows developers to write less code, achieve more functionality, and enhance the user experience on websites.
| 2. How to include jQuery in an HTML file? | |
Ans. To include jQuery in an HTML file, you can either download the jQuery library and host it on your server, or you can use a content delivery network (CDN) to include it directly from a remote server. For example, you can include jQuery using a CDN by adding the following code within the `<head>` tag of your HTML file:
```html
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
```
| 3. How to select elements using jQuery selectors? | |
Ans. jQuery provides a wide range of selectors to select elements based on their attributes, classes, IDs, and more. You can use the `$()` function with a selector as an argument to select elements. For example, to select all the paragraphs in an HTML document, you can use the following code:
```javascript
$("p")
```
This will return all the `<p>` elements in the document.
| 4. How to bind a click event to an element using jQuery? | |
Ans. To bind a click event to an element using jQuery, you can use the `.click()` method. You can pass a function as an argument to the `.click()` method, which will be executed when the element is clicked. For example, to bind a click event to a button with the ID "myButton", you can use the following code:
```javascript
$("#myButton").click(function(){
// Code to be executed when the button is clicked
});
```
| 5. How to make an Ajax request using jQuery? | |
Ans. jQuery provides the `.ajax()` method to make Ajax requests. You can pass an object with various properties to the `.ajax()` method to configure the Ajax request. For example, to make a GET request to a URL and handle the response, you can use the following code:
```javascript
$.ajax({
url: "https://api.example.com/data",
method: "GET",
success: function(response){
// Code to handle the response
},
error: function(error){
// Code to handle the error
}
});
```
This will make an Ajax request to the specified URL and execute the success function when the request is successful, or the error function when there is an error.
Text Transcript from Video
hi this is Alex from PHP academy' de org
and this is a video tutorial for the new
Boston in this tutorial we're going to
be looking at the jQuery click event now
as discussed in previous tutorials we
are keeping the in inline JavaScript
we're basically eradicating and we're
not trying to keep it as minimal as
possible we're just getting rid of it so
in this tutorial we're going to look at
the click event which is an extremely
well used or highly used event due to
the fact that when we click on things we
want them to hide show update etc now in
this tutorial we're going to look at a
button that's going to be able to be
clicked we're going to use jQuery to
listen for the events so we're going to
create an event handler and then we're
going to show a particular bit of
information such as a paragraph so let's
go ahead and first of all create our
markup which is going to allow us to see
what we need to do so the first thing
we're going to create is a button and
this button is going to be type button
and the value of this is going to be
hide the ID of this we're going to give
it an ID of hide message now remember
that ID uniquely references this button
so this element on the page so we can
use jQuery to reference when we want the
hide message button to be clicked or
we're going to look out for when it is
clicked the next thing we're going to do
is create a paragraph let me just bring
this down and this is going to be this
is a message so essentially what we're
doing is we're clicking this button to
show this div or to hide this div sorry
let's go back and click refresh our page
in our browser you can see that we've
got the paragraph here this is a message
and also the hide button as well so when
we click that that should hide okay so
now what we want to do is ensure we have
jQuery included on our page at the at
the bottom of our
body bottom of our body area we now want
to create a separate file that's going
to handle the clicking of this button so
we can call it anything we like we're
not really talking about file structure
or naming conventions but I'm just going
to go ahead and create a file inside the
jas folder and I'm just going to call
this click J s so click J s is going to
handle the event and the function that
we carry out when this button is clicked
so let's go ahead and do that now so the
first thing we want to do is reference
the element so we use a dollar sign and
then in brackets we use a textual
representation of the element name and
this starts with a hash and remember the
name of the button was hide underscore
message so we just go ahead and write
hide underscore message now we need the
event handler and this is dot click and
then we end it with two parenthesis and
a line terminator semicolon now dot
click handles this event
so when hide message is complete
everything inside this put in this in in
these parentheses will be taken into
account now what we need is a function
that lets us carry out an event once
this click handler has has realized that
the button has been clicked so we need
to create a function inside of this here
so we create a function as we usually
would with parentheses we obviously
don't take any arguments because we're
just going to be carrying out a block of
code essentially we need a starting
block and an ending block using curly
brackets but what I'm going to do is I'm
going to bring these down a couple of
lines and in so now we have this
workspace in here to write the code we
want to happen when the hide message
button is clicked so essentially this
could be written all on one line like
this and but you can now understand why
we bring it down and start to work in
here so now what we want to do is
actually hide the button so or hide the
paragraph so again reference the
paragraph so
hache message remember we cooled the
paragraph only we didn't so we need to
give that an ID so the idea of message
so we've given the i/o this paragraph an
ID of message then we reference it with
here hash message and then we just say
dots hide and then we use brackets
you'll notice the color difference
between click and hide hide is a
function well I mean click is an event
handler and hide is actually a function
so ok now that we've done that when the
hide message is clicked we're going to
actually hide this message now there's
one thing we need to do beforehand and
that's include this click j/s file onto
our page so we type in here script type
is equal to text JavaScript so the type
attribute is JavaScript and we also need
to give that a source as well as ending
the paragraph just ending the script tag
just there that's j/s forward slash
click J s so now that this now that this
is all set up we have no inline code at
all but we have an event handler to
handle the clicking of this button let's
go ahead and test it in our browser I'm
just going to go ahead and refresh the
page
when I click hide you'll see that the
message is hidden now a bit later on
we're going to be looking more at the
hide function in jQuery and things that
we can pass to it different parameters
we can pass to it however for now we
have just created out a first event
handler which is click now there are
many more event handlers that you'll see
coming up in the rest of this series but
for now this is probably the most basic
and most used event handler which is a
clicking on a specific element now
you'll also notice that we don't just
have to apply this to buttons we could
of course get rid of this input here and
use a link so let's go ahead and type
hide
and the hrf is nothing we just put hash
in here so we don't reload the current
page but we don't not do anything and
the ID of this is going to be hide
message now this code will work with the
change we've just made we're referencing
hide message and we're saying when it's
clicked hi the message so let's go and
look at the difference that we've just
made there we've got a link instead of a
button when we click it we get exactly
the same effect and you'll see this hash
here that I was talking about earlier
that will crop up and you've probably
seen it on a lot of other websites but
that's not really anything to worry
about
so we've now created a link that hides a
message and I highly encourage you to go
ahead and create some other elements on
a page how you'd also you know hide an
element it can be used with most HTML
elements
and this is a video tutorial for the new
Boston in this tutorial we're going to
