Ajax success event not working on mobile phone

I have a problem. I'm developing a website for my photos. The registration is working well on computer, but I have some problems on my mobile device (android).

I'm using jquery ajax:

beforeSend: function(){
$("#load").css({"display":"block"});
}

The beforeSend function should display the loader div with a loading.gif. On Computer browser it is working well, but on my mobile device it doesn't hide and the success message does not show. It all works perfectly on computer browser. Perhaps you can help me.

This is the whole jquery code:

$(":button").click(function(e){

    e.stopImmediatePropagation();

      var benutzername = $("input[name=benutzername]").val();
      var passwort = $("input[name=passwort]").val();
      var email = $("input[name=email]").val();


      var characterReg = /^[A-Za-z0-9_]{5,20}$/;
        if(!characterReg.test(benutzername)) {
            $("input[name=benutzername]").val("");
            $(".text-input:nth(0)").html("Mindestens 5 Buchstabend, Zahlen. Keine Sonderzeichen oder Umlaute.");
                $("input[name=benutzername]").focus(function(){
                    $(".text-input:nth(0)").html("");
                });

        }else{
            var emailReg = /^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i;
            if(!emailReg.test(email)) {
                $("input[name=email]").val("");
                $(".text-input:nth(1)").html("Gebe bitte eine richtige E-Mail Adresse an.");
                    $("input[name=email]").focus(function(){
                        $(".text-input:nth(1)").html("");
                    });

            }else{
                var passwortReg = /^[A-Za-z0-9!@#$%^&*()_]{6,20}$/;
                    if(!passwortReg.test(passwort)) {
                        $("input[name=passwort]").val("");
                        $(".text-input:nth(2)").html("Mindestens 6 Zeichen plus Sonderzeichen (!@#$%^&*()_). Keine Umlaute");
                            $("input[name=passwort]").focus(function(){
                                $(".text-input:nth(2)").html("");
                            });

                    }else{
                        if ($('input:checkbox').is(':checked')) {
                               $.ajax({
                                    type: "POST",

There is a problem with your code, string does not have method 'contains'.

if(!html.contains("entry")){

In Firefox 18 - 36, the name of this method was called "contains". It was renamed to "includes"

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/includes#String.prototype.contains

Use indexOf instead, like it mentioned here How to check whether a string contains a substring in JavaScript?
