How to change my current code to support smart phone

I am using simplemde. My current code is
```

var simplemde;
setTimeout(function(){
if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
// some code..
}else{
if (simplemde){
location.reload()
}else{
simplemde = new SimpleMDE();
}
}
}, 300);

```
Please update this code, so that I can include toolbar for mobile devise also. I am newbie to code.
