Question

Oracle Apex 4.2和Oracle 12c

例如。

Within apex plsql region I have this code to creating drop down list 
  <button id="Clickme" onclick="myFunction()">Click me</button>
 <br>
 <select name="F01" class="mySelect">
    <option value="0"></option>
    <option value="1">Yes</option>
    <option value="2">No</option>
</select><br>
<select name="F01" class="mySelect">
    <option value="0"></option>
    <option value="1">Yes</option>
    <option value="2">No</option>
</select><br>
<select name="F01" class="mySelect">
    <option value="0"></option>
    <option value="1">Yes</option>
    <option value="2">No</option>
</select><br>
<select name="F01" class="mySelect">
    <option value="0"></option>
    <option value="1">Yes</option>
    <option value="2">No</option>
</select>

等等

在页面加载标题之后我有一个创建localsession的进程，因为默认值应该来自db表

例如。

localStorage.setItem('SetDefaults','[{"id":"1","attribute1":"Yes"},{"id":"2","attribute1":"Yes"},{"id":"3","attribute1":"N/A"},{"id":"4","attribute1":"N/A"}]');

因此，当页面加载时，所有下拉列表都为空，但是当单击“按钮”时，下拉项目应根据上述localStorage数据显示默认值。我在页面上有5列的原因，每列与第1列相同，但应根据按钮显示不同的数据。

请帮忙吗？

- 一些HTML代码 - //下拉列表类'Listcls'

<select name="F03" class="selectlist Listcls " "="" size="1" data-obs="1">
                    <option value=""></option>
                    <option value="Yes">Yes</option>
                    <option value="No">No</option>
                    <option value="N/A">N/A</option>
      </select>

- 单击按钮时获取默认值的javascript代码但是我无法确定如何在单击按钮时显示json值。

// Button class  'BtnCls'

    $('.BtnCls').on('click', function() {
      var vdef = [{"id":"1","attribute1":"Yes"},{"id":"2","attribute1":"Yes"},{"id":"3","attribute1":"N/A"},{"id":"4","attribute1":"N/A"},{"id":"5","attribute1":"N/A"},
      {"id":"6","attribute1":"N/A"},{"id":"7","attribute1":"N/A"},];
      var vdefault =  JSON.parse(JSON.stringify(vdef));
      for (var i = 0; i < vdefault.length; i++) {
            var obs = vdefault[i].attribute1;
    // dropdown list class  'Listcls'

      //  $('.Listcls').css('background-color', 'grey'); -- working for testing

         }

});

Oracle Apex Region基于PLSQL和HTML
