You can use the File reader object.

var reader = new FileReader();
var fileSource = <here is your file path>

reader.onloadend = function(evt) {

if(evt.target.result == null) {
   // If you receive a null value the file doesn't exists
} else {
    // Otherwise the file exists
}         
};

// We are going to check if the file exists
reader.readAsDataURL(fileSource);
