jQuery offers many methods to help developers effectively create a dynamic web experience. The jQuery html () method replaces all HTML in the selected element. This is useful if you want to dynamically change what the user sees after interacting with the page.

In this guide, we will learn how to use html () and its syntax. We’ll also take a step-by-step approach to using html (). jQuery html () is a fundamental method of the jQuery library and is often used. After you’ve learned the basics, you’ll be ready to start practicing with html ().

What is jQuery html ()?

jQuery html () sets the HTML content of each element into a set of matching elements. Care should be taken to provide a query that is sufficiently precise to replace only the HTML you want.

Only content is edited with html (). If there is a style sheet, the new content will have the same style as the previous content. It’s also worth mentioning that html () only works on HTML document - it doesn’t work with XML.

html () jQuery syntax

Remember that jQuery methods are first called on a selector. The selector can be as large as a

tag or as specific as ). Once we have selected the desired element, we can call html () and pass an HTML string as a parameter to html (). For a detailed explanation of CSS selectors, see our guide .

html () accepts a literal string as a parameter or a variable containing the string. Passing a literal string of "New Content" will be rendered as passing a variable referring to "New Content".

Suppose we have this simple

We can replace the entire

tag:

The code above shows the new HTML as:

If there was a style associated with the original

tag , it would no longer be active with the new content. It is also possible to pass a simple string:

Our code HTML is now as follows:

We can see that there is has some differences in the new content. Passing a literal string is a great way to keep the style of the previous content. Remember that a literal string is just a string containing characters. If the new content is to be a child element, using an HTML string allows you to do this.

Now that the basic syntax has been covered, let’s take a look at an example.

jQuery html () example

We have seen how html () replaces the content in the selected element in our "New Content" example . This can be achieved by passing a literal string or an HTML string as a parameter. Let’s take a look at an example where we keep the original style.

Looking at our initial HTML page, we will only see the word "Hello" stylized with the color blue.

In this example, we want to replace the word " Hello " with new content, while keeping the original style. To do this, we select the paragraph with the name of the blue class.

We have selected the paragraph belonging to the blue class and replaced "Hello" with "Hello AGAIN". Since html () replaces the content included in the element names, the blue color will remain.

< Figure class = "wp-image-block"> A83aaFCGA71IBKWgL4WyaFqn GeP4fN7kwWBtZnN4Xmhk9dfSP85teVs83FA2w8myG0SsPwzmfMP8RagLyBGr0JCb8XgEpQ88AFUpD 5iatEp Im3xzfqRKD35rOb9xjhLoN1Na

What if we want to replace all the text in the paragraph ? If we select the

element, it will replace the above text with three instances of " Hello AGAIN. ‚"

Here we select the entire paragraph of tags in the HTML file and replacing the content of each with "Hello AGAIN". or placing envelop content pe in these tags.

Just as we hoped. Let’s go up one level in our selector to our JXF9suUYnrtQvrU 8sIs3 NEA0BBS2hKkyRaigcZX26RHBcDZ376i87EpwGAsBEBYNaIjVUs FAsrMupPlC9CduIwFUCCBGj Ol64YUdUPWEKZYgZX26RHBcDZ376i87EpwGAsBEBYNaIjVUs FAsrMupPlC9CduIwFUCCBGj XGT XGT Ol64YUdUPWEKZYXX6D has our element>. </ p Knowing how to <code>html () </code>, one can infer that the code above - above replace the three <p>tag with the one passed as a parameter. Read our <a href= guide on learning HTML to learn more about the above

En one line of code, we’ve replaced three different paragraph elements and used our own original class style .

< h2> Conclusion

jQuery html () is a commonly used method to replace the content of HTML pages to create a dynamic experience. Since html () replaces content included in HTML elements, it is important to be careful with jQuery selectors and style classes. This will prevent any unwanted style change.

We learned what jQuery is, its syntax and an example of use. Spend time practicing and developing this widely used method.

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
