Solution

Using JavaScript:

// Get the element
let element = document.querySelector(‘#elementId’);

// Get the value of the element
let value = element.value;

// Remove the class from the value
let newValue = value.replace(/\bclassName\b/g, ”);

// Set the new value
element.value = newValue;

//using string instead of reading value of the input aka var str = $(".foo").val();
var str = "2 + 5 = <span class="emphasis">7</span>";
//convert the string to html
var temp = $("<div>").html(str);
//find the span and unwrap it
temp.find(".emphasis").contents().unwrap();
//get the html string without the span
var updated = temp.html();
//display it
console.log(updated);

Removing a class from a value in an HTML tag can be a tricky task. Fortunately, there are a few methods that can be used to accomplish this. The first method is to use the removeAttribute() method. This method can be used to remove any attribute from an HTML element, including classes. To use this method, you must first select the element you want to remove the class from. Then, you can call the removeAttribute() method on the element, passing in the name of the attribute you want to remove. For example, if you wanted to remove the class “example” from an element, you would use the following code:

element.removeAttribute("class");

The second method is to use the classList object. This object contains a list of all the classes associated with an element. To remove a class from this list, you can use the remove() method. This method takes the name of the class you want to remove as an argument. For example, if you wanted to remove the class “example” from an element, you would use the following code:

element.classList.remove("example");

Finally, you can also use the replace() method to remove a class from an element. This method takes two arguments: the old class name and the new class name. If you pass in an empty string as the new class name, the old class will be removed. For example, if you wanted to remove the class “example” from an element, you would use the following code:

element.className.replace("example", "");

These are just a few of the methods you can use to remove a class from an HTML element. With a little bit of practice, you should be able to easily remove classes from any element.
