点击文本框显示模式框，在模式框选中单选值，显示在文本框中

如：jsp:
      <input class="i3" type="text" name="textfield" id='select4passer${index}'onclick='open_Dialog(this);' value="中国"/>
function open_Dialog(obj)
{
var win = window.showModalDialog("country.jsp",window,"dialogWidth=425px;dialogHeight=300px;center=yes;status=no");
if(win != null)
{
    //document.getElementById("parentTextBox").value = win;
   // alert(obj.id);
    var str=win.split(";");
    if(str.length>0){
    // alert(str[0]);
     //赋值
     document.getElementById(obj.id+"hidden").value=str[1];
     document.getElementById(obj.id).value=str[0];

    }
}
}
