在javascript中读取struts2 <s:datetimepicker中的值

<s:datetimepicker id="time1" name="time1" toggleType="explode" value="today" /> 
<s:datetimepicker id="time2" name="time2" toggleType="explode" value="today" />

我们在javascript中可以通过以下方式读取和赋值

var time1= dojo.widget.byId("time1");
var stringtime1 = time1.getValue();//读取
var time2= dojo.widget.byId("time2");
time2.setValue(stringtime1 ); //赋值

以上代码，取出time1中的值，赋给time2

Struts2 API中的一个例子:
Examples:

<s:datetimepicker name="order.date" label="Order Date" />
<s:datetimepicker name="delivery.date" label="Delivery Date" displayFormat="yyyy-MM-dd"  />
<s:datetimepicker name="delivery.date" label="Delivery Date" value="%{date}"  />
<s:datetimepicker name="delivery.date" label="Delivery Date" value="%{'2007-01-01'}"  />
<s:datetimepicker name="order.date" label="Order Date" value="%{'today'}"/>

Getting and getting the datetimepicker value, from JavaScript:

<s:datetimepicker id="picker" label="Order Date" />

<script type="text/javascript">
  function setValue() {
     var picker = dojo.widget.byId("picker");
     
     //string value
     picker.setValue('2007-01-01');
     
     //Date value
     picker.setValue(new Date());
  }
  
  function showValue() {
     var picker = dojo.widget.byId("picker");
     
     //string value
     var stringValue = picker.getValue();
     alert(stringValue);
     
     //date value
     var dateValue = picker.getDate();
     alert(dateValue);
  }
</script>

Publish topic when value changes:

<s:datetimepicker id="picker" label="Order Date" valueNotifyTopics="/value"/>

<script type="text/javascript">
dojo.event.topic.subscribe("/value", function(textEntered, date, widget){
    alert('value changed');
    //textEntered: String enetered in the textbox
    //date: JavaScript Date object with the value selected
    //widet: widget that published the topic 
});
</script>
