Asp net core 2 0 set focus on a input element

Introduction

ASP.NET is a popular programming language used for building web applications. One common requirement in web development is to set focus on a specific input element. In this article, we will explore how to achieve this using ASP.NET Core 2.0.

Setting Focus on an Input Element

To set focus on an input element in ASP.NET Core 2.0, we can use JavaScript. We will add a script tag to our HTML page and use the focus() method to set focus on the desired input element.

In the above example, we assume that the input element has an id of “myInput”. The getElementById() method is used to select the input element, and the focus() method is called to set focus on it.

Example

Let's consider a scenario where we have a form with multiple input elements, and we want to set focus on the first input element when the page loads.

    Name:
    


    
    Email:
    


    
    Message:
    


    
    

In the above example, we have a form with three input elements: name, email, and message. We have added a script tag at the end of the HTML code to set focus on the “name” input element using its id.

When the page loads, the cursor will automatically be placed in the “name” input field, allowing the user to start typing without having to manually select the input field.

Conclusion

Setting focus on an input element in ASP.NET Core 2.0 can be achieved using JavaScript. By using the focus() method, we can easily set focus on the desired input element. This improves the user experience by automatically selecting the input field when the page loads.

By following the examples provided in this article, you can easily implement this functionality in your ASP.NET Core 2.0 web applications.
