FAQs on jQuery Tutorial - 47 - Hide/Show a DIV Video Lecture - Importance of jQuery in Website Development - IT & Software
| 1. How can I hide a DIV element using jQuery? |  |
Ans. You can hide a DIV element using jQuery by using the `.hide()` method. This method sets the CSS `display` property of the selected element to "none", effectively hiding it from view. Here's an example:
```javascript
$("#myDiv").hide();
```
This code will hide the element with the ID "myDiv".
| 2. How can I show a hidden DIV element using jQuery? | |
Ans. To show a hidden DIV element using jQuery, you can use the `.show()` method. This method sets the CSS `display` property of the selected element to its default value, making it visible again. Here's an example:
```javascript
$("#myDiv").show();
```
This code will show the element with the ID "myDiv" if it was previously hidden.
| 3. Can I toggle the visibility of a DIV element using jQuery? | |
Ans. Yes, you can toggle the visibility of a DIV element using jQuery. The `.toggle()` method can be used to switch between hiding and showing an element. If the element is visible, it will be hidden, and if it is hidden, it will be shown. Here's an example:
```javascript
$("#myDiv").toggle();
```
This code will toggle the visibility of the element with the ID "myDiv".
| 4. How can I check if a DIV element is currently hidden using jQuery? | |
Ans. To check if a DIV element is currently hidden using jQuery, you can use the `.is()` method in combination with the `:hidden` selector. The `:hidden` selector selects all elements that are currently hidden. Here's an example:
```javascript
if ($("#myDiv").is(":hidden")) {
console.log("The element is currently hidden.");
} else {
console.log("The element is currently visible.");
}
```
This code will log a message indicating whether the element with the ID "myDiv" is hidden or visible.
| 5. Can I specify the speed of the hide/show animation in jQuery? | |
Ans. Yes, you can specify the speed of the hide/show animation in jQuery by using the optional `duration` parameter of the `.hide()` or `.show()` methods. The `duration` parameter specifies the animation duration in milliseconds. Here's an example:
```javascript
$("#myDiv").hide(1000);
```
This code will hide the element with the ID "myDiv" with a 1000 milliseconds (1 second) animation duration. You can adjust the duration value as per your requirement.
Text Transcript from Video
hi this is Alex from PHP academy' de org
with a video tutorial for the new Boston
in this example video we are going to
take a look at how to hide and show a
div with some text inside of it and also
then change the show and hide buttons
simultaneously so let's go ahead and
start to build up our message that we
want to display and then we're gonna
have a button or a link that's going to
allow us to hide and show it so we're
essentially toggling it
okay so let's create our div I'm going
to give this an ID of message just a
generic name for the text that's going
to be inside of it inside I am going to
just paste in some example text some
Latin text now the div ID I'm going to
style in line which I've always said I
don't recommend however for the purpose
of this tutorial and just to make things
quick I will just create a style inside
of here so the first thing I'm going to
do is just set a width I'm then going to
set a border to this and that's gonna be
one pixel solid and I'm gonna have it a
sort of gray color and I'm also gonna
set some padding so padding 10 pixels
okay so let's preview that in our
browser you can see that we've got some
text inside of a div with just a light
gray border okay so let's go over to our
text editor and create the link above
this div that's going to hide and show
it so I'm just going to create a link
here the link is going to be just a hash
because we're not actually linking to
anything but the idea of this is going
to be show or hide show and then here
the initial text that we're going to
display will be hide so now if we
preview that that's going to look like
that so the idea that we want to come
across is when we press hide this will
actually hide this whole area here the
bordered area and then this hide text
will change to show and then when we
click on show this will be
shown once again and then again this
will change to hide so it's really just
a case of this link changing and this
being shown or hidden and then shown
again so let's go ahead and create our
JavaScript file and I'm going to call
this message Jas and I'm gonna include
that in my page just under here so
script type is text forward slash
JavaScript and we'll include that by
putting that in the source so Jas
forward slash message Jas okay so now
that we've done that we want to go ahead
and actually edit our message gif file
to handle the events based around this
link so the first thing we want to do is
actually toggle this hide and show
button and what I mean by toggle is
we've looked at in this series how to
actually change something based on when
we for example click on it so what I'm
going to do is reference this button and
that's called hide show and then I'm
gonna say dot toggle so we're using the
dot toggle or the toggle event handler
now inside here we need two functions
the first function is going to be what
happens when this link is clicked for
the first time and then the second
function is going to be what happens
when it is clicked again and we revert
back to its original state
so we're toggling between two different
states so I'm going to create one
function and it's block and then I'm
going to separate this by a comma and
create another function and this block
now let's pull these blocks down so we
can work with it a bit easier so now in
here this is the first state so we'll
call that state 1 and in here this is
state 2 so when we click this button
state 1 will happen then we when we
click it again state 2 will happen when
we click the link again it will revert
back to the original state and it will
switch between the two so what we
actually want to do is we want to modify
the text here hide to show instead so we
can again reference hide show
but this time we use the text function
to change the text within this link so
essentially what we're doing is we are
changing this text here so we can
specify that when it's clicked we want
to show now in the second state we want
to do exactly the same thing so we can
just copy and paste this down here
however we want it to display hired
instead okay so let's go over to our
browser and preview these changes so at
the moment the button shows hide when I
click on it it now shows show when I
click on again it goes back to hide and
this will just continue because we've
used the toggle event handler okay so
that's all well and good but now we
actually need to hide this div now there
are two ways that we could do it we
could include it inside this buttons
functionality or we can do it outside
I'm going to do it outside for the
purposes of this tutorial and then I'm
going to show you the inside as well
okay so we need an event handler for our
message so we're referencing our message
div and we're going to say dot actually
no we don't we need to show you need to
say hide show so hide show dot click
okay and then this will in itself this
is in itself an event handler we need a
function inside of here that will do
something every time we click this hide
show button now what we can actually do
in this case is we can reference the
message div and actually just use the
toggle function now the toggle function
will work exactly the same as this event
handler but it'll just hide and show
this message div every time we click on
the hide show link so when we click this
link this will disappear then it will
toggle back to it being reappeared so
let's just check out how that works so
at the moment we've got a hide button
when we click on hide you can see that
the div has been hidden when we cook
show it's toggled back to its original
state and it's now visible and we can
continue to do this over and over again
now obviously including this
code here is entirely unnecessary what
we could actually do is we could copy
and paste this here and delete this here
and we could actually place it inside of
here
so what's happening is when we click
this a hide/show button the toggle event
is triggered we hide the div inside of
this bit here so we could hide the
message and then exactly the same in
here but we could show it so we've
actually every time we've pressed the
top at the hide/show link we change the
text to show and we hide the message div
when we press it again we hide it we
give the detects the display of hide but
we actually show the div so now if we
refresh you can see that this works in
exactly the same way so there's a
variety of different ways you can
actually create things like this however
this basic functionality is extremely
useful for any any anything you want to
hide and show now this could apply to
menu options for example you could have
a tiered menu with subcategories so when
you click on say the main category
you'll show a list of subcategories you
can then click on the main menu again to
hide these it can be used for a control
panel for example for a user if you have
particular settings you wanted the user
to change but you wanted to keep them
all hidden and shown you can actually
allow the user to show certain parts of
the settings that they can change so I'm
sure you've seen this example used on a
wide variety of websites however the
functionality behind it is actually
quite basic so just by using this code
we've enabled this div to be shown and
what are the visibility to be hidden and
shown and also change the text of the
button using the text function as well
