How to hide a label using Javascript?

Using Javascript, how do you make开发者_如何转开发 a label invisible on a button click?

I'm not sure what you want but here goes:

<label id="mylabel">Woot!!</label>

button.onclick = function() {
  document.getElementById("mylabel").style.display = "none";
}

Just from the top of my head

<input type="button" onclick="document.getElementById('labelname').style.display = 'none';" />

A label is rendered as span tag in HTML. If you know the id of any the control you can turn off its visibility through JavaScript by

document.getElementById('your-element-id').style.display='none';
