Hi @chuxinhao,

Is the file an asset in your Playcanvas project?

If that’s the case you can more simply do this (make sure your asset names are unique):

if( this.app.assets.find('MyHtmlFile.html') !== null){

   // asset exists
}

If you are asking how to check if an external url exists, you need to make a GET request and check the result. Playcanvas provides an easy to use http requests class:
