将类添加到动态 JSON 值

Question

我有一个动态用户列表，其中包含各种行业的各种职业，具体取决于他们的行业（健康、教育、建筑、科学等），我想添加一个颜色徽章，根据不同行业动态显示用户所在行业，快速区分用户一目了然。该代码在硬编码 html 环境中以文本值为目标时运行良好，但在尝试引用从动态 JSON.

加载的文本值时似乎出现故障

我已经包含了下面的代码。

如有任何帮助，我们将不胜感激！

谢谢，史蒂夫

添加新元素时添加class。

您可以使用一个对象来保存行业名称和相应徽章 classes 之间的映射，因此您不需要所有这些 if 语句并且可以将其用于静态和动态代码。

const industry_class = {
  "Health": "health-badge",
  "Education": "education-badge",
  "Construction": "construction-badge",
  "Science": "science-badge"
};

//THIS IS THE CODE TO REFERENCE EXTERNAL JSON FILE
var userJSON = 'https://mighty-oasis-08666.herokuapp.com/users'

//THIS IS THE CODE TO FETCH EXTERNAL JSON FILE
$.getJSON(userJSON, function(populateUsers) {

  //THIS IS THE CODE TO POPULATE JSON DATA INTO TEMPLATE LITERAL CARD
  var userCard = populateUsers.map(({id, name, username, email, phone, company, industry}) => {
    let cls = industry_class[industry.trim()] || "";
    return `
            <div class='col col-4 align-items-stretch strain-container'>
                <div id="${id}" class="card user-card">
                    <div class="card-body">
                        <h2 class="title">${name}</h2>
                        <h6 class="title">${username}</h6>
                        <h6 class="title">${email}</h6>
                        <h6 class="title">${phone}</h6>
                        <h6 class="title">${company}</h6>
                        <h6 class="industry-type title ${cls}">${industry}</h6>
                    </div>
                </div>
            </div>`;
  }).join("");
  $('#user-grid').append(userCard)
});

var $industryType = $('.industry-type');

$industryType.each(function() {
  var $this = jQuery(this);
  let industry = $this.text().trim();
  if (industry in industry_class) {
    $this.addClass(industry_class[industry]);
  }

});

.health-badge {
  background-color: purple;
  color: green;
  height: 80px;
  width: 80px;
}

.science-badge {
  background-color: black;
  color: yellow;
  height: 80px;
  width: 80px;
}

.construction-badge {
  background-color: blue;
  color: white;
  height: 80px;
  width: 80px;
}

.education-badge {
  background-color: orangered;
  color: black;
  height: 80px;
  width: 80px;
}
