How to switch classes in Blazor on button click?

Question

I currently have an onclick event that switches classes like this:

....
<button id="@m.TargetCo.ButtonId" onclick="glyphChanger(this.id)" class="btn btn-default iconButton glyphicon glyphicon-chevron-right" ></button>
....
function glyphChanger(buttonID) {
    $("#" + buttonID).toggleClass('glyphicon-chevron-right glyphicon-chevron-up');
}

Answer 1

No JavaScript required. You can do this the Blazor way.

DropDownComponent.razor

Debug: @buttonCss
Test

@code {
    private string buttonCss = "glyphicon-chevron-right";
    private void ChangeButtonClass()
    {
        buttonCss = buttonCss == "glyphicon-chevron-right" ? "glyphicon-chevron-up" : "glyphicon-chevron-right";
    }
}
