Where should I put javascript files?
You can create a new folder in the wwwroot directory, and then create your JavaScript file (e.g., myScript.js) inside this folder.
In the myScript.js file, define your JavaScript functions:
function myJsFunction() {
alert('JavaScript function called from Blazor!');
}
Where and how should I reference... reference files?
You can add a reference to the JavaScript file in the wwwroot/index.html file:
<script src="js/myScript.js"></script>
Then you can call the JavaScript function from a Blazor component:
@inject IJSRuntime JS
<button @onclick="CallJsFunction">Call JavaScript Function</button>
@code {
private async Task CallJsFunction()
{
await JS.InvokeVoidAsync("myJsFunction");
}
}
