What is jQuery removeClass ()?

The jQuery removeClass () method removes class attributes from a selected element. The removal of class attributes can be global or specific as needed. Class attributes are assigned in the HTML file and styled through CSS.

Using jQuery to communicate between HTML and CSS offers the possibility of creating more responsive web applications. By incorporating removeClass () and removing the class attribute, developers can essentially "turn off" the CSS styling of HTML. removeClass () is often used in conjunction with addClass ().

addClass () is the inverse of removeClass and shares syntax practices. Learn more about addClass () in this guide .

How jQuery removeClass () works

removeClass () removes class attributes from a selected element. Let’s say we have a

Let’s start with jQuery selector $ to select all

tags . Calling removeClass () without parameters will simply remove all class attributes from the selected items. In the current state of our code, our

tags are not styled.

Let’s remove a single class attribute from our

tags.

$ (’p’). removeClass (’primaryClass’)

Here we have passed the class name primaryClass to our removeClass () method. This removes all class attributes from the

tags with the class name primaryClass. Now only these

tags are not styled, leaving the other

tags belonging to a different class intact.

removeClass () can accept many class names such as parameters. Write them with a space in between like this:

$ (’p’). RemoveClass (’classOne classTwo classThree’)

This removes the class from all

tags with a class name of classOne, classTwo, or classThree.

Now that we’ve covered the basic syntax of removeClass () , let’s take a look at some examples.

Examples jQuery removeClass ()

Let’s expand our example

tag to include all three syntaxes. Iniziamo impostando la nostra pagina HTML di base.

Our basic HTML looks like this:

CmUO6KnoG0y098QveHGoBHPYQ4 982pv9Xd3gUGTMYW2UYAp L05v3QYQSYRBB9BLm4SsAPfHDQejca7t4 EJA8IluWGl0jIOJ2MY8e4pHsGC730W8p PPP 6cxeCVkzWLLxJ4YB

not pass removeClass () all parameters, we can remove all class attributes from the

tag .

$ (’p’). removeClass ()

Now our HTML page looks like this:

AsZNxz95Ij0qAOYLr H2eYDrGUMuNygpsqi9sYRBnqLPJeqkvbZ2gqvlaXDRWbrwPRmwNPyJRW8NPM I02an0K7HuL IpzquKmAzxYKFBRciyHPhYbNkKZRFLkDPxr XWhtiEVdu

Exactly what we expected! Now let’s remove the class attributes from all

tags belonging to the "green" class.

$ (’p’). RemoveClass (’green’)

This should remove the green color from the words "Hello" and "Goodbye". The purple highlight on the word "World" and the strikethrough on "Goodbye" will remain intact. & nbsp;

F6QbWUn4xwuOKf0j8A7y2kdXbXhRhdoYLTUkgbhCNxuFrsjk2FSLRcncbV5NW9WwochuE K2c4khsDbb075 SqOPnQBOXw1To22uX5ZKUdCkLcepCvA3enlx18epjkZ4xGkYLAgc

Excellent! We pass two class names to removeClass (). We can remove the purple highlight and strikethrough in a line of code:

$ (’p’). removeClass (’highlight strike’)

We should now see the color green go back to "Hello" and & ldquo; Goodbye & rdquo ;.

We have seen removeClass () remove all or part of the class attributes according to the parameters passed. Let’s recap what we’ve learned so you can practice your new skill!

Conclusion

jQuery removeClass () removes class attributes from the selected element. If no parameter is passed to removeClass (), it simply removes all attributes from the element. It is able to select multiple class names as parameters, so a combination of deletion is possible in a single line of code.

Class attributes can be more complex than colors. These can be animations or any number of behaviors you want. By removing class attributes, we are essentially "turning off" those behaviors. As you become more familiar with the removeClass () method, try using removeClass () with a jQuery event listener to create a dynamic user experience .

How can I make a time delay in Python?

5 answers

I would like to know how to put a time delay in a Python script.

2973

Answer #1

import time
time.sleep(5)   # Delays for 5 seconds. You can also use a float value.

Here is another example where something is run approximately once a minute:

import time
while True:
    print("This prints once a minute.")
    time.sleep(60) # Delay for 1 minute (60 seconds).

2973

Answer #2

You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.

from time import sleep
sleep(0.1) # Time in seconds
