javascript - 向容器中插入内容

下面是重新创建类似 google 的图像搜索的代码。如果您单击一个框，它会在该框和字段下打开。基本上我希望每个框在您单击它们时都有自己的图像和描述。

如何在该信息框中插入图像和标题或段落？

var container = $('.container');
var elements = container.children();
var oldWrapPos = 0;

$('.box').click(function() {
  container.children().removeClass('selected'); // reset selected element
  $(this).addClass('selected'); // mark new selected element
  var selectedPos = $(this).index(); // get selected position
  // find wrap element:
  //var containerWidth = container.width();
  //var elementsInRow = Math.floor(containerWidth / 100 );
  var elementsInRow = 4; // use this if container's width is fixed
  var row = Math.floor(selectedPos / elementsInRow) + 1;
  var wrapPos = (row * elementsInRow);

  // if selected is on last row, use as wrap the last element:
  var size = elements.length;
  if (wrapPos >= size) {
    wrapPos = size;
  }
  wrapPos = wrapPos - 1;
  console.log(selectedPos);
  console.log(elementsInRow);
  var pointerPos = 40 + ((selectedPos % elementsInRow) * 110)
  console.log(selectedPos % elementsInRow);
  console.log((selectedPos % elementsInRow) * 110);
  console.log('left: ' + pointerPos);
  console.log(size);
  // next line added by CrocoDillon, didn't do any cleanup of old calculations :P
  pointerPos = $(this).position().left + $(this).width() / 2 - 10;
  // end edit;
  if (wrapPos == oldWrapPos) {
    $('.info-pc').css("left", pointerPos + 'px');
  } else {
    oldWrapPos = wrapPos;
    elements.removeClass('edge');
    $(elements[wrapPos]).addClass('edge');
    $('.info-bg').slideUp(function() {
      $(this).remove();
    });
    $('.edge').after('<div class="info-bg"><div class="info-pc" style="left:' +
      pointerPos + 'px"></div><div class="info-cl"></div></div>');
    $('.info-bg').slideDown();
  }
});

$('html').click(function(e) {
  if (e.target == this)
    $('.info-bg').slideUp(function() {
      $(this).remove();
    });
});

.container {
  width: 440px;
  margin: 0 auto;
  position: relative;
}

.info-bg {
  width: 430px;
  height: 70px;
  background-color: red;
  float: left;
  position: relative;
  margin: 5px;
  display: none;
}

.info-cl {
  height: 100%;
}

.info-pc {
  position: absolute;
  border-bottom: 10px solid red;
  border-left: 10px solid transparent;
  border-right: 10px solid transparent;
  height: 0;
  width: 0;
  float: right;
  top: -10px;
}

.box {
  width: 100px;
  height: 170px;
  background-color: grey;
  float: left;
  margin: 5px;
  font-size: 40px;
}

.edge {
  background-color: yellow;
}

.selected {
  background-color: red;
}

最佳答案

d然后您可以在框的 html 中添加标题/描述信息，并从那里阅读。我在这条评论下添加了代码: //这里添加内容还将 info-bg 的高度更改为 min-height 以保持其灵 active

var container = $('.container');
var elements = container.children();
var oldWrapPos = 0;

$('.box').click(function(){
    container.children().removeClass('selected'); // reset selected element
    $(this).addClass('selected'); // mark new selected element
    var selectedPos = $(this).index(); // get selected position
    // find wrap element:
    //var containerWidth = container.width();
    //var elementsInRow = Math.floor(containerWidth / 100 );
    var elementsInRow = 4; // use this if container's width is fixed
    var row = Math.floor(selectedPos / elementsInRow)+1;
    var wrapPos = (row * elementsInRow);
    
    // if selected is on last row, use as wrap the last element:
    var size = elements.length;
    if (wrapPos >= size){wrapPos = size;}
    wrapPos = wrapPos - 1;
    console.log(selectedPos);
    console.log(elementsInRow);
    var pointerPos = 40 + ((selectedPos % elementsInRow) * 110)
    console.log(selectedPos % elementsInRow);
    console.log((selectedPos % elementsInRow) * 110);
    console.log('left: '+pointerPos);
    console.log(size);
    // next line added by CrocoDillon, didn't do any cleanup of old calculations :P
    pointerPos = $(this).position().left + $(this).width() / 2 - 10;
    // end edit;
    if (wrapPos == oldWrapPos){
        $('.info-pc').css("left", pointerPos+'px');
    } else {
        oldWrapPos = wrapPos;
        elements.removeClass('edge');
        $(elements[wrapPos]).addClass('edge');
        $('.info-bg').slideUp( function() { $(this).remove(); });
        $('.edge').after('<div class="info-bg"><div class="info-pc" style="left:'
                         +pointerPos+'px"></div><div class="info-cl"></div></div>');
       
        $('.info-bg').slideDown();
    }
    //adding content here
    var content = $('.info-bg').find('.info-cl');
    content.html(''); //empty previous content
    var title = $('<h2>');
    title.text($(this).data('title'))
    var description = $('<p>');
    description.text($(this).data('description'))
    content.append(title).append(description);
});

$('html').click( function (e) { 
    if ( e.target == this )
        $('.info-bg').slideUp( function() { $(this).remove(); });
});

.container{
    width: 440px;
    margin: 0 auto;
    position: relative;

.info-bg{
