How to dynamically insert an id into a table element using JavaScript?

In this article, we will learn how to dynamically insert IDs into table elements using JavaScript with the help of setAttribute API.

In web development, dynamically inserting IDs into HTML table elements can be a useful technique when we need to uniquely identify and manipulate specific rows or cells. By programmatically assigning IDs to table elements, we gain more control and flexibility in accessing and modifying table content.

Let's go through some examples to understand how to achieve this.

Example 1

In this example, we generate random IDs for table rows by counting the total number of available rows and appending that count to an empty string.

File name: index.html

Row
            
Data
         
      
      Add Row
      
   

Example 2

In this example, we will follow the above code pattern and generate random ids for table cells using 3 different methods with the help of classList method, classList object and id property of dataset object. < /p>

Row
            
Data
         
      
      Add Row Using classList object
      
         Add Row Using classList method
      
      Add Row Using the id property
      
   

in conclusion

In summary, using JavaScript to dynamically insert IDs into table elements enables efficient manipulation and interaction with specific elements in the table. In the provided example, we learned how to dynamically insert IDs into table rows and cells. By leveraging JavaScript methods like insertRow, insertCell, etc. and manipulating the id attribute, we generate unique IDs and associate them with the corresponding table elements.
