How can I get the values selected in the drop-down list, using a JavaScript function? User can select multiple values from both the elements. Following are the elements I'm using. Thanks in advance.

<select name="icOptions" id="icOptions" style="display: none" multiple="multiple">
  <option value="Choose an Option" selected="selected">Choose a Team </option>
  <option value="IDX">IDX</option>
  <option value="Support">SUPPORT</option>
  <option value="webapps">WEBAPPS</option>
</select>

<select name="ocOptions" id="ocOptions" style="display: none" multiple="multiple">
  <option value="Choose an Option" selected="selected">Choose a TeamMember </option>
  <option value="sanjay740">sanjay740</option>
  <option value="milind740">milind740</option>
</select>

Answer 1

var fld = document.getElementById('icOptions');
var values = [];
for (var i = 0; i < fld.options.length; i++) {
  if (fld.options[i].selected) {
    values.push(fld.options[i].value);
  }
}
// do something with values
