当从Dojo中的Checked Multi Select（“ dojox.form.CheckedMultiSelect”）中选择一个选项时如何写条件？

Question

我需要编写代码来对列表执行某些操作，具体取决于从Dojo中的Checked Multi Select（“ dojox.form.CheckedMultiSelect”）中选择的选项。在dojo中选择一个（或多个）选项时，如何编写条件？

<select multiple="true" name="multiselect" data-dojo-type="dojox.form.CheckedMultiSelect" data-dojo- 
 attach-point="mslt" dropDown="true"> 
    <option value="one" selected="selected" data-dojo-attach-point="chkWQT">Option-1</option>
    <option value="two" selected="selected" data-dojo-attach-point="chkWQL">Option-2</option>
</select>

Javascript：

if (//Option-1 is selected) {
  layerList.push.apply(List, Resources_GRP);

}

Answer 1

var opt = this.mslt.getOptions();
if (opt[1].selected) {
    //Statement
}
