<script language="javascript" type="text/javascript"> function move（formObj,toObj）{ if（formObj.selectedIndex ！= -1）{ toObj.add（new Option（formObj.options[formObj.selectedIndex].text,formObj.options[formObj.selectedIndex].value））; formObj.remove（formObj.selectedIndex）; //var index = formObj.selectedIndex; } } </script> <form name="form1"> <table> <tr> <td> <select multiple name="left" size=7 ondblclick="move（this,this.form.right）"> <option value="0" selected>item1</option> <option value="1">item2</option> <option value="2">item3</option> <option value="3">item4</option> <option value="4">item5</option> </select> </td> <td > <input type="button" name="moveRigth" value=">>" onclick="move（this.form.left,this.form.right）"/> <input type="button" name="moveLeft" value="<<" onclick="move（this.form.right,this.form.left）"/> </td> <td> <select multiple name="right" size=7 ondblclick="move（this,this.form.left）"> <option value="0" selected>test1</option> <option value="1">test2</option> <option value="2">test3</option> <option value="3">test4</option> <option value="4">test5</option> </select> </td> </tr> </table> </form>
