How do I open browser dialog to load without NW.JS/FileChoos

var global = Function('return this')(); //get global scope.

global.openFileDialog = function(fileType) { 
 // this function must be called from  a user
 // activation event (ie an onclick event)

    // Create an input element
    var inputElement = document.createElement("input");

    // Set its type to file
    inputElement.type = "file";

    // Set accept to the file types you want the user to select. 
    // Include both the file extension and the mime type
    inputElement.accept = fileType;

    // set onchange event to call callback when user has selected file
    inputElement.addEventListener("change", function (event) {

    [...this.files].forEach(file => {
        //var s = file.name;
var url = URL.createObjectURL(file);
        c2_callFunction("GetFileFromDialog", [url]);
    });

     } );

    // dispatch a click event to open the file dialog
    inputElement.dispatchEvent(new MouseEvent("click")); 
};[/code:46st2m3i]

An execute javascript with "openFileDialog();" on sprite clicked or whatever.

Is a bit of workaround but seems works on any browsers and NW.JS. 

If somebody know another solution/way, let me know.
