Dynamic create default check box

When you create a check box in IE using document. createelement, you cannot set checked = true to make the check box selected by default.

But in Firefox

Therefore, use innerhtml = '<input type = "checkbox" Checked = "true"> </input>' to create the default check box

Both IE and Firefox

<SCRIPT type = "text/JavaScript" src = "prototype-1.5.1.js"> </SCRIPT>
<SCRIPT type = "text/JavaScript">
Function createcheckbox ()
VaR ocheckbox = Document. createelement ("input ");
Ocheckbox. setattribute ("type", "checkbox ");
Ocheckbox. setattribute ("checked", true );

If (! Ocheckbox. Checked)
Ocheckbox. Checked = true;

$ ("Container"). appendchild (ocheckbox );
Alert (ocheckbox. Checked );

Function createcheckbox2 (){

$ ("Container"). innerhtml = '<input type = "checkbox" Checked = "true"> </input> ';


<Div id = "Container" style = "height: 100px; width: 100%">


<Input type = "button" onclick = "createcheckbox ()" value = "create check box"> </input>
<Input type = "button" onclick = "createcheckbox2 ()" value = "create check box 2"> </input>
