Trigger Onclick Programmatically

Question

I have a div that provides some functionality when clicked.
However I want to call this click also when I initialize the page.

<div id="test1" @onclick="MyFunction()">
...
</div>

code {
...
protected override async Task OnAfterRenderAsync(bool firstRender)
{
if (firstRender)
{
test1.Click(); // I WANT TO TRIGGER THE CLICK IN HERE
//for this specific application I couldnt call MyFunction() directly in here... it needs to be called via the click event
}
}

Any help ?

Thx

Hi @ANB , from your description of this question, I think you want to use DOM.Click() instead of calling the onclick method directly in OnAfterRenderAsync() method. Please refer to this simple demo.

Create a js file called MyScript.js in wwwroot:

var BlazorTest = BlazorTest || {};  
BlazorTest.setClick = function (element) {  
    element.click();  
};  

refer this js file in index.cshtml

Then in your Razor Component
