假设我想在多选屏幕（类型 = 4）中验证至少选择了一个复选框。如何在以下示例中定义相关验证的条件？

<question title="Preferrable Colors" type="4" key="#1">
  <answer nextQuestionKey="END" key="#1_1"  position="0">
    <text>Pink</text>
  </answer>
  <answer nextQuestionKey="END" key="#1_2"  position="1">
    <text>Red</text>
  </answer>
  <answer nextQuestionKey="END" key="#1_3"  position="2">
    <text>Violet</text>
  </answer>
  <text>Select the colors you prefer </text>
  <validation type="ERROR">
    <condition>true</condition>
    <text>Sorry, you have to select at least one color</text>
  </validation>
</question>

在此静态场景中满足您的要求的一种简单方法是使用 isAnswerSelectedByClientKey 方法查看每个答案的“已检查状态”。此方法将返回真或假，在我的方法中，我将所有“状态”写入一个数组，然后检查是否存在真。

            <question title="Preferrable Colors" type="4" key="#1">
            <answer nextQuestionKey="END" key="#1_1" position="0">
                <text>Pink</text>
            </answer>
            <answer nextQuestionKey="END" key="#1_2" position="1">
                <text>Red</text>
            </answer>
            <answer nextQuestionKey="END" key="#1_3" position="2">
                <text>Violet</text>
            </answer>
            <text>Select the colors you prefer </text>
            <validation type="ERROR">
                <condition>hasValue(selArray, true) == false</condition>
                <text>Sorry, you have to select at least one color</text>
            </validation>
            <onLeaveOkPrepareAssignment>
                selArray = null;        
                selArray['1'] = isAnswerSelectedByClientKey($answer:'#1_1', null);
                selArray['2'] = isAnswerSelectedByClientKey($answer:'#1_2', null);
                selArray['3'] = isAnswerSelectedByClientKey($answer:'#1_3', null);          
            </onLeaveOkPrepareAssignment>
        </question>

您可以将条件定义为：

<condition>getQuestionValueNew() == ""</condition>

因此，当未选择任何内容时true，它将返回，如果选择了某些内容，则返回false。
