Question

I have an app with web view, where I display a feedback HTML page, I need just to display a wait indicator when user touch the HTML submit button, and maybe better also to disable the submit button in HTML form.

either a solution from iOS side or HTML/Javascript side will be OK.

Answer 1

If you have a form with the name and id “myForm”, a button with id “myButton” (that button cannot be of type or name “submit”) and an empty div with id “waitMessage” where you could insert a wait message or a gif, then you could use something like this:

var myButton1 = document.getElementById("myButton");

myButton1.onclick = function (){
   getElementById("waitMessage").innerHTML = "Whatever waiting message or html code you want";
   myButton1.disabled=true;
   document.forms["myform"].submit();
}
