C# Razor For Loop JavaScript

Introduction

C# Razor is a server-side programming language that allows developers to create dynamic web pages. It also gives you the ability to write server-side code and use JavaScript to manipulate client-side objects.

One of the most commonly used control structures in C# Razor is the for loop. In this article, we will discuss how to use the for loop with JavaScript in C# Razor.

Syntax of the For Loop in C# Razor

The syntax of a for loop in C# Razor is as follows:

@for(var i = 0; i < count; i++)
{
  // statements
}

• count is a variable that specifies how many times the loop should run.
• i is a variable that is used to keep track of the number of iterations.

Using JavaScript in a For Loop

You can use JavaScript to manipulate client-side objects within the for loop. For example, you can use JavaScript to change the background color of an object.

@for(var i = 0; i < count; i++)
{
  <script>
    var element = document.getElementById('div' + i);
    element.style.backgroundColor ='red';
  </script>
}

In the above example, JavaScript is used to get a reference to an HTML element with an ID of 'div' + i, where i is the current iteration. The background color of the element is then changed to 'red'.

Conclusion

Using the for loop with JavaScript in C# Razor allows developers to create dynamic web pages that can interact with client-side objects. By following the syntax of the for loop, developers can execute a block of code multiple times, allowing them to manipulate client-side objects such as colors or text.
