setAttribute onClick with a variable as parameter?

Question

Is this possible? And if so, how?¨ Is it possible to setAttribute onclick=myFunction() with a variable as parameter?

var variableCross = localStorage.getItem('cross'+localStorage.getItem('number'));
del.setAttribute("onClick","myFunction(variableCross);");

myFunction(variableCross); sends variable like a string? doesn't it?

thx

Do you know the name of the JS variable at the time you are adding this attribute? — StingyJack

and how to do it if i shouldn't set events with setAttribute? — Dwadelfri

Create a global variable inside the javascript scope, and reference the variable inside the function. if you need the value. del.setAttribute("onClick","myFunction("+VARIABLE+");"); — DJ.

Assuming this bit of code does what you want

var variableCross = localStorage.getItem('cross'+localStorage.getItem('number'));

Then this should work for you

del.addEventListener("click", function(event) {
  myFunction(variableCross);
  event.preventDefault();
});

You retrieve you local storage values and pass them as string to you function by simply:

    this.getElementById('button1').setAttribute("onClick","alert("+variableCross.toString()+");");

here is the example:
