You can use the following object:

var idGenerator  = {
    seq: 0,
    generateId: function () {
       this.seq++;
       return (new Date()).toISOString().substring(0, 10) + '-' + ('000' + this.seq).substr(-4)
    }
}

after declaration like this, try

function generateID() {
   var TheTextBox = document.getElementById("generateidtxt");
   TheTextBox.value = TheTextBox.value + idGenerator.generateId();
   document.getElementById("generateid").disabled=true;    
}
