dojo中取DateTextBox中的值两种方法

前端之家收集整理的这篇文章主要介绍了dojo中取DateTextBox中的值两种方法前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

1、第一种方法

通过JavaScript中的document.getElementById("startDate").value取值

<script type="dojo/on" data-dojo-event="click" data-dojo-args="evt">
      var startDate = document.getElementById("startDate").value;
      var endDate = document.getElementById("endDate").value;
      alert("开始日期:" + startDate + "\n" + "结束日期:" + endDate);
</script>
2、第二种方法

通过dojo中的dijit.byId("startMonth").get('displayedValue')取值

 <script type="dojo/on" data-dojo-event="click" data-dojo-args="evt">
       var startMonth = dijit.byId("startMonth").get('displayedValue');
       var endMonth = dijit.byId("endMonth").get('displayedValue');
       alert("开始月份:" + startMonth + "\n" + "结束月份:" + endMonth);
</script>
