Question

我试图制作一个简单的列表，向我展示数组中每个div的div叠加层，但是我在定义每个div时遇到了问题。

我当前的java / jQuery脚本涉及为数组中的每个对象创建一个div以及一个背景图像（我也遇到链接问题。虽然我有一个在线链接工作的背景图片。）。

我想要做的是为列表中的每个项目提供一个叠加层，然后将来使用相同的代码来提供打开链接或显示图像预览的功能，但这是另一个列表的内容

那么，我怎样才能让叠加层为每个div工作而不是按类行动。我能够为每个对象数组创建一个包含所有所需设置的div，以及叠加层。

您可以在我的文档就绪函数中找到当前隐藏/显示每个叠加div的代码。

我想将其定义为个别divs＆＃39;在数组而不是全部。

$(document).ready(function() { 
  displayDesign();
  $( ".pagesListOverlay" ).mouseenter(function() {
    $( ".pagesListOverlay" ).hide()  ;
  });
});
var arrayVariableDesign = [
  {name: "object1", type:"type1", company:"company1", dateYear:"2017", dateMonth:"08", dateDay:"24", image:"../images/preview/noimg.png"},

    temp_Design = document.createElement('div');
    temp_Design.className = 'pagesListBtn mobilePagesListBtn';
    temp_Design.style.background = "url(" + arrayVariableDesign[i].image.src + ")"; // https://stackoverflow.com/questions/9790347/set-an-image-object-as-a-div-background-image-using-javascript
    temp_Design.style.backgroundSize = "100%";
    temp_Design.style.backgroundRepeat = "no-repeat";
    temp_Design.style.backgroundPosition = "50% 50%";
    temp_Design.style.backgroundColor = "#C02024";
    temp_Design.innerHTML = "<div class='pagesListOverlay mobilePagesListOverlayBtn'>" + arrayVariableDesign[i].name + " for " + arrayVariableDesign[i].company + "<br>" + arrayVariableDesign[i].type + "<br>" + arrayVariableDesign[i].dateDay + "/" + arrayVariableDesign[i].dateMonth + "/" + arrayVariableDesign[i].dateYear + "</div>";
    document.getElementById("demo").appendChild(temp_Design);
  }
}

＆＃13;

.pagesListBtn {
  z-index: 500;
  background-color: #C02024;  
  display: inline-block;         
}

.pagesListBtn:hover {
  background-color: #920400;    
}

.pagesListOverlay {
  padding-top: 0;
  margin: 0 auto;
  opacity: 0.8;
  display: inherit;
  background-color: white; 
  text-align: center;
  vertical-align: bottom;
  text-decoration:none;
  font-weight:900;
  line-height:30px;
}

.mobilePagesListBtn {
  min-height:150px;
  max-height:150px;
  width: 100%; /*295px*/
  padding: 0;
  margin-top: 25px;
  margin-bottom: -15px;
}

.mobilePagesListOverlayBtn {
  min-height:150px;
  max-height:150px;
  width: 100%; /*295px*/
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js"></script>
<div id="demo"></div>

＆＃13;

我也遇到了这个代码的其他两个问题。

图片链接不起作用，我只是从我的css文件中复制并粘贴
我到处都收到了很多严格的陈述。 - 我通过添加＆＃34;使用strict＆＃34;;我的代码。

感谢您的帮助。

您必须在父mouseenter上应用mouseleave和.pagesListBtn。从$(this)起，.pagesListBtn悬停，找到孩子pagesListOverlay来显示/隐藏它。

＆＃13;

$(document).ready(function() { 
  displayDesign();
  $( ".pagesListBtn" ).mouseenter(function() {
    $( this ).find(".pagesListOverlay").fadeOut(800)  ;
  });
  $( ".pagesListBtn" ).mouseleave(function() {
    $( this ).find(".pagesListOverlay").fadeIn(800)  ;
  });
  
  
});
var arrayVariableDesign = [
  {name: "object1", type:"type1", company:"company1", dateYear:"2017", dateMonth:"08", dateDay:"24", image:"../images/preview/noimg.png"},
  {name: "object2", type:"type1", company:"company1", dateYear:"2017", dateMonth:"01", dateDay:"20", image:"../images/preview/noimg.png"},
  {name: "object3", type:"type2", company:"company2", dateYear:"2016", dateMonth:"08", dateDay:"24", image:"../images/preview/noimg.png"},
  {name: "object4", type:"type3", company:"company3", dateYear:"2016", dateMonth:"03", dateDay:"04", image:"../images/preview/noimg.png"},
  {name: "object5", type:"type1", company:"company2", dateYear:"2017", dateMonth:"02", dateDay:"24", image:"../images/preview/noimg.png"},
  {name: "object6", type:"type2", company:"company1", dateYear:"2017", dateMonth:"08", dateDay:"20", image:"../images/preview/noimg.png"},
];
var arrayLength_Design = arrayVariableDesign.length;
var temp_Design;
    
function displayDesign() {
    
  for (i = 0; i < arrayLength_Design; i++) { 
    var sortDate_Design = arrayVariableDesign[i].dateYear + arrayVariableDesign[i].dateMonth + arrayVariableDesign[i].dateDay;
    temp_Design = document.createElement('div');
    temp_Design.className = 'pagesListBtn mobilePagesListBtn';
    temp_Design.style.background = "url(" + arrayVariableDesign[i].image.src + ")"; // https://stackoverflow.com/questions/9790347/set-an-image-object-as-a-div-background-image-using-javascript
    temp_Design.style.backgroundSize = "100%";
    temp_Design.style.backgroundRepeat = "no-repeat";
    temp_Design.style.backgroundPosition = "50% 50%";
    temp_Design.style.backgroundColor = "#C02024";
    temp_Design.innerHTML = "<div class='pagesListOverlay mobilePagesListOverlayBtn'>" + arrayVariableDesign[i].name + " for " + arrayVariableDesign[i].company + "<br>" + arrayVariableDesign[i].type + "<br>" + arrayVariableDesign[i].dateDay + "/" + arrayVariableDesign[i].dateMonth + "/" + arrayVariableDesign[i].dateYear + "</div>";
    document.getElementById("demo").appendChild(temp_Design);
  }
}

＆＃13;

.pagesListBtn {
  /*z-index: 500;*/
  background-color: #C02024;  
  /*display: inline-block;*/
  display:block;
}

.pagesListBtn:hover {
  background-color: #920400;    
}

.pagesListOverlay {
  padding: 0;   /* changed */
  margin: 0;    /* changed */
  height: 150px;    /* added */
  opacity: 0.8;
  display: inherit;
  background-color: white; 
  text-align: center;
  vertical-align: bottom;
  text-decoration:none;
  font-weight:900;
  line-height:30px;
}

.mobilePagesListBtn {
  height: 150px;      /* added */
  /*min-height:150px; 
  max-height:150px;*/
  width: 100%; /*295px*/
  padding: 0;
  margin-top: 25px;
  /*margin-bottom: -15px;*/
}

.mobilePagesListOverlayBtn {
  /*min-height:150px;
  max-height:150px;*/
  padding:0;    /* added */
  height: 150px;
  width: 100%; /*295px*/
}
