Replace quotation marks with \"

Question

I am working with a html-page with some javascript on it. What I'm trying to do is to show a message and a button after pressing submit-button. On pressing this new button the document state should go to its previous state. My attempt:

function Submin()
{
  var str=document.Inputs.innerHTML;
  newstr = str.replace("\"", "\\\"");
  document.Inputs.innerHTML="<p style=\"text-align:center\">The data has been successfully submitted <br /><input type=\"button\" value=\"Back\" onclick=\"document.Inputs.innerHTML=\\\"" + newstr + "\\\" \/></p>";
}

I am totally confused by escaping and double escaping things. But in my opinion it should work somehow like this. Can sombody help me on this solution?

First, you can use single quotes inside your double quoted string. Second, don't use inline event handlers here. Your best bet is to use a real event handler:

function Submin() {
    var str=document.Inputs.innerHTML;
    document.Inputs.innerHTML="<p style='text-align:center'>The data has been successfully submitted <br /><input type='button' value='Back' ></p>";
    document.Inputs.getElementsByTagName("input")[0].onclick = function() {
        document.Inputs.innerHTML = newstr;
    };
}

Thanks, you were a great help! – Danny Lo Dec 09 '12 at 14:26 — Danny Lo, Dec 09 '12 at 14:26
