单击列表项目时消失

标签： javascript jquery html css

好的，所以我正在尝试为一些随机生成的人建立一个叠加层。这是一个我正在研究的项目，你可以通过一些jQuery和AJAX动态地随机用户，我已经把它们列出来并列出但我需要能够点击它们，它们就像一个模态窗口一样出现。这就是问题所在。当你点击它们时我会显示它们但它们会在页面上消失。造成这种情况的原因是什么？如何解决？忽略模态的节奏我不担心CSS。 

let html = "";

$.ajax({
  url: 'https://randomuser.me/api/?results=5000',
  dataType: 'json',
  success: function(data) {
    html += "<ul>"
    for (i = 0; i < 12; i++) {

      html += "<li>";
      html += "<img src=" + '"' + data.results[i].picture.medium + '">';
      html += "<div id='main'>"
      html += "<h3>" + data.results[i].name.first + " " + data.results[i].name.last + "</h3>";
      html += "<p>" + data.results[i].email + "</p>";
      html += "<p>" + data.results[i].location.city + "</p>";
      html += "<p class='popup'>" + data.results[i].phone + "</p>"
      html += "<p class='popup'>" + data.results[i].location.street + ", " + data.results[i].location.state + " " + data.results[i].location.postcode + "</p>";
      html += "<p class='popup'>" + data.results[i].dob + "</p>"
      html += "</div>";
      html += "</li>";
    }
    html += "</ul>"
    $("#employeeList").html(html);

    $("li").on("click", function() {
      $(".overlay").css("display", "block");
      $(".modal").html(this);
      $(".modal").preventDefault();
    });

    $(".overlay").on("click", function() {

抱歉关于所有内容，但我被困住了。提前谢谢!!

这是因为你将“this”传递给了模态，所以我认为最好只复制这样的内容

    $("li").on("click", function () {
      var $li = '<li>' + this.innerHTML +'<li>';
      $(".overlay").css("display", "block");
      $(".modal").html($li);
      //$(".modal").preventDefault();
    });


let html = ""; 

$.ajax({

  success: function(data) {
    html += "<ul>"
    for(i = 0; i < 12; i++) {

       html += "<li>";
       html += "<img src=" + '"' + data.results[i].picture.medium + '">';
       html += "<div id='main'>"
       html += "<h3>" + data.results[i].name.first + " " + data.results[i].name.last + "</h3>";
       html += "<p>" + data.results[i].email + "</p>";
       html += "<p>" + data.results[i].location.city + "</p>";
       html += "<p class='popup'>" + data.results[i].phone + "</p>"
       html += "<p class='popup'>" + data.results[i].location.street + ", " + data.results[i].location.state + " " + data.results[i].location.postcode + "</p>";
       html += "<p class='popup'>" + data.results[i].dob + "</p>"
       html += "</div>";
       html += "</li>";
    }

答案 1 :(得分：0)

复制li并传入副本，而不是传入原始的li节点。同时接受回调中的event参数，并致电event.preventDefault而不是$(".modal").preventDefault以解除preventDefault is not a function错误。

$("li").on("click", function (event) {
    event.preventDefault()
    $(".overlay").css("display", "block");
    $(".modal").html($(this).clone());
});

你可能会改变一些事情。

  1. 您的循环中有一个全局i
  2. 你的循环中有一个重复的id='main'，产生无效的html，使用一个类
  3. 不确定.preventDefault();正在阻止什么......但是应该使用该事件呢？我评论了它。
  4. 为什么你的html宣告成功？
  5. 为什么在成功事件处理程序中有事件处理程序附件？
  6. 在重叠事件处理程序中，您再次搜索它，使用this
  7. 使用.show()和.hide()比使用css更容易，因为你已经在使用jQuery，添加一个.hidden类来隐藏起初。
  8. 一些分号丢失了 - 不是一件大事，但为什么强迫解析器插入它们。
  9. 您可以克隆节点并在其他位置显示其内容。
  10. img src=奇怪的引用，使用单引号

    11. 我还使用变量r来使代码更易于阅读

    var i=0;
    for (i=0; i < 12; i++) {
      let r = data.results[i];
      html += "<li>";
      html += "<img src='" + r.picture.medium + "'>";
      html += "<div class='main'>";
      html += "<h3>" + r.name.first + " " + r.name.last + "</h3>";
      html += "<p>" + r.email + "</p>";
      html += "<p>" + r.location.city + "</p>";
      html += "<p class='popup'>" + r.phone + "</p>";
      html += "<p class='popup'>" + r.location.street + ", " + r.location.state + " " + r.location.postcode + "</p>";
