createElement 範例

這個還蠻好用的
Support Browser：Chrome (目前只用這個測過)

<script type="text/javascript">
function makeForm(){
  // -  create the form element and it's attributes
  var f=document.createElement('form');
  f.setAttribute('name','myForm');
  f.setAttribute('action','createElement_test.html');
  f.setAttribute('target','_blank');
  f.setAttribute('method','get');

var formText=document.createTextNode('Enter your name: ');

  // -  next, create a text input where you'll enter your name
  var yourName=document.createElement('input');
  yourName.setAttribute('type','text');
  yourName.setAttribute('name','NAME');
  yourName.setAttribute('value','');

  // -  create a submit input to submit the form
  var b=document.createElement('input');
  b.setAttribute('type','submit');
  b.setAttribute('value','click to test this form');

  // -  finally, append the text node, the text input, and the submit input to the form
  f.appendChild(formText);
  // -  put a line break between the text node and the inputs
  f.appendChild(document.createElement('br'));
  f.appendChild(yourName);
  f.appendChild(b);
  document.getElementById('formTest').appendChild(f);
}
</script>

function add_radioBlock(whichID)

    infoPanel.innerHTML = '';
    var radio, form1, but_submit;
    var argv='';
    var map=2; //dynimages

    form1 = document.createElement('form');
    form1.setAttribute('method', 'post');
    form1.setAttribute('action', 'Shilin_district.jsp');

    for(var i = 0; i < Taiwan_county[whichID].length; i++)
    {
        argv="CountyImage('RightBlock'," + map + ", 0)";  //可以把變數用字串組合好後
        radio = document.createElement('input');
        radio.setAttribute('type', 'radio');
        radio.setAttribute('name', 'chooseOnecounty');
        radio.setAttribute('value', i+4);
        radio.setAttribute('id', i+4);
        radio.setAttribute('onMouseover', argv);  //再丟進去，（這樣就可以丟function了）
        form1.appendChild(radio);
        form1.innerHTML += Taiwan_county[whichID][i] + '<br>';
    }
    but_submit = document.createElement('input');
    but_submit.setAttribute('type', 'submit');
