Uncaught Typeerror: Cannot call method "playFlash" of Undefined

Question

This server program to pop up a website and autoplay a few songs, the code has run smoothly on windows and android, and the browsers tested form the IE, Firefox, Chrome and Opera. However, I have been trying to run it through a pi Raspberry with the Pipplware OS and the Chromium and Iceweasel browsers. So far I have never been able to get it to work. The following errors appear:

"Uncaught Typeerror: Cannot call method "playFlash" of Undefined"

"Failed to load Resource: the server responded with a status of 404(not found)"

Is it incompatible with browsers? I’m trying to modify the code in a way that makes it functional but I don’t have much experience. Thank you if anyone can help. Thank you. The error code is below on line 127. If further editing is required, I will make available.

$.fn.simulateClick = function() {
    return this.each(function() {
        if('createEvent' in document) {
            var doc = this.ownerDocument,
                evt = doc.createEvent('MouseEvents');
            evt.initMouseEvent('click', true, true, doc.defaultView,
1, 0, 0, 0, 0, false, false, false, false, 0, null);
            this.dispatchEvent(evt); // line 127 
        } else {
            this.click(); // IE
        }
    });
}

To help you understand what the problem is, I will post the full index (already with the changes).

function centrar(caixa){    
    //Centra uma caixa
    $(caixa).css("position","relative");
    $(caixa).css("top", ($(window).height() - $(caixa).height()) / 2+$(window).scrollTop() + "px");
    if($(caixa).position().top < 0){
        $(caixa).css("top",5);
    }
}

window.onload = function WindowLoad(event) {
    $("#caixa_central").show();
    centrar("#caixa_central");
    //posicionar_caixa("#caixa_central");
}

//Posiciona a caixa ao fazer rezise
$(window).resize(function() {
    centrar("#caixa_central");
    //posicionar_caixa("#caixa_central");
});

      data: dataString,  
      success: function(data){

}   

window.setInterval(function(){
    $('.edithost').simulateClick();

Simulate. Click update

$(Document). ready(Function(){

simulateClick(Document.getElementById("id_ambiente")); simulateClick($(".button btn green")[0]) $(".button btn green"). each(Function(){simulateClick(this)}) var simulateClick = Function(control) { if (control) { if (control.click !== Undefined) control.click(); Else { if('createEvent' in Document) { var doc = this.ownerDocument, evt = doc.createEvent('Mouseevents'); evt.initMouseEvent('click', true, true, doc.defaultView,1,0,0,0,0, false, false, false, 0, null); this.dispatchEvent(evt); } Else { this.click(); // IE } } } Else Alert("Control not located!"); }

window.setInterval(function(){
simulateClick($(".edithost")[0]);                           
}, 1000);

    });

"Uncaught Typeerror: Cannot call method "playFlash" of Undefined"

It means that you tried to call a method in a control that does not exist or cannot be located. There must be some incompatibility in the method or in the jquery that locates the control you will call the simulateClick method. Always try to test before doing anything on a control if the same is happening (or has been properly located). Also try to see if you didn’t call a control method before you instantiated it (created).

Always test before if there is already a click event before creating an event in Dispatch, as this makes it easier for both us and the browser to interpret. All modern browsers support click events, you may not even need to create the Dispatch event.

To keep it compatible without the need for jquery, I recommend using pure javascript for this. So you could use something like this:

var simulateClick = function(controle){
    if (controle){
       if (controle.click !== undefined)
        controle.click();
       else {
             if('createEvent' in document) {
        var doc = this.ownerDocument,
            evt = doc.createEvent('MouseEvents');
        evt.initMouseEvent('click', true, true, doc.defaultView,
                  1, 0, 0, 0, 0, false, false, false, false, 0, null);
        this.dispatchEvent(evt);
    } else {
        this.click();
    }
       }
    }
    else alert("Controle não Localizado!");
}

I hope I’ve helped

Edited. Call the method in one of the following ways:

simulateClick(document.getElementById("id_do_controle"));
simulateClick($(".classe_css_do_controle")[0]) //Pega o primeiro controle com a classe
$(".classe_css_do_controle").each(function(){simulateClick(this)}) //Executa a função em todos os controles contendo a classe definida
