How to use jQuery to Search and Replace HTML elements?

In this article, we will discuss on how to use jQuery to search and replace HTML elements. Just like in Vanilla JavaScript (pure JavaScript), jQuery also comes up with selectors for selecting the HTML tags so that we can manipulate the content and properties of the HTML tags. Using the jQuery selectors  we can select elements by tag name, Id name, Class name and also by the location of the tag. 

In the following example, we use two jQuery methods: one to add content to the existing HTML tags and another to add new HTML tags in the body.

1. text( ) : The method selects the tag and the argument to the text function appends text to the pre-existing tags. The argument is HTML safe meaning the content will be exactly copied to the tag irrespective of HTML code passed as an argument.

2. html( ) : The method selects the tag and the argument to the html function adds the content to the selected tag. It is HTML specific meaning that it will check if the argument is an HTML content and add it accordingly.

    <button class="two">Add Me!</button>
    <br>
    <span></span>
    <script type="text/javascript">
        $(".one").click(function()
        {
            $("h1").text("Geeks for Geeks!");
        });
  
        $(".two").click(function()
        {
            $("span").html("<h3>You can also Contribute.</h3>");
        });
    </script>
</body>
</html>

Other Important jQuery functions : 

3. css( ) : The method is used to select and manipulate the CSS properties of the element.

4. attr( ) :  The method returns and changes the attribute of an HTML tag.

5. val( ) :  The method returns value of all the tag which have the value attribute. It can also set the value by passing argument to it.

If one wants to add multiple CSS properties to a tag then the more appropriate method is to give properties to a class and then remove, add or toggle class into a tag. This property makes jQuery very easy to use and handle.

jQuery provides addClass( ),  removeClass( ),  and toggleClass( ) to add, remove and toggle a class to a tag in HTML.
