_submitSpan.appendChild(submit);

i created a form and append a input button, but i found it can’t work in IE6, when click the button, the form auto submitted. can anybody help me.thank you.

Instead of explicitly setting the onclick attribute, try binding dynamically to the nodes’ onclick event instead. Or perhaps you should be looking at the onsubmit event of the form.

function bindEvent(target, event, handler) {
    if (typeof target.addEventListener != 'undefined') {      
        target.addEventListener(event, handler, false);
    } else if (typeof target.attachEvent != 'undefined') {
        target.attachEvent('on' + event, handler); 
    } 
}


function check(e) {
   // Cancel W3 DOM events
   if (typeof e.preventDefault != 'undefined') {
        e.preventDefault();
   }
   // Cancel for old IE event model
   e.returnValue = false;

   return false;
}

var submit = document.createElement("input");
submit.type = "image";
submit.src = "submit1.gif";

_submitSpan.appendChild(submit);

// Bind click event to submit button...
bindEvent(submit, 'click', check);

// ...or perhaps you want to bind submit event to form
bindEvent(submit.form, 'submit', check);
