微信小程序实现答题样式

今天群里有人问了一个问题,怎么实现单选题和多选题在单击时选中,想着反正也没啥事,就写个demo试试看,代码如下:

首先在data里面添加问答题,如下:

data: {
    quest: [{
      id: 1,
      type: 1, //类型,1.单选,2.多选
      question: "1.你有女朋友吗?(单选)",
      answers: [{
        content: 'A.有'
      }, {
        content: 'B.没有'
      }]
    }, {
      id: 2,
      type: 1,
      question: "2.目前薪资在哪个范围?(单选)",
      answers: [{
        content: 'A.3-6k'
      }, {
        content: 'B.6-8k'
      }, {
        content: 'C.8-10k'
      }, {
        content: 'D.10k以上'
      }]
    }, {
      id: 3,
      type: 2,
      question: "3.你喜欢哪一种编程语言?(多选)",
      answers: [{
        content: 'A.Java'
      }, {
        content: 'B.C语言'
      }, {
        content: 'C.PHP'
      }, {
        content: 'D.Python'
      }, {
        content: 'E.JavaScript'
      }, {
        content: 'F.其他'
      }]
    }]
  },

然后在wxml文件里面显示问答题,代码如下:


  {{item.question}}
  
    {{item.content}}
  

对应的绑定事件如下:

answerSelected(e) {
    let outidx = e.currentTarget.dataset.outidx;
    let idx = e.currentTarget.dataset.idx;
    let question = this.data.quest[outidx];
    if (question.type == 1) {
      //单选
      for (let item of question.answers) {
        item.selected = false;
      }
      question.answers[idx].selected = true;
      this.setData({
        quest: this.data.quest
      });
    } else if (question.type == 2) {
      //多选
      question.answers[idx].selected = !question.answers[idx].selected;
      this.setData({
        quest: this.data.quest
      });
    }
  },

最终效果如下:
