onclick当前使用jquery的DIV显示

html jquery javascript

Husna · 技术社区 · 6 年前

我在这里处理图像库。我想在.gallery容器中单击“图像当前图像显示”,该容器工作正常,但问题是当前图像标题不显示,因为我在jquery中以图像源为目标,试图添加标题,但无法实现。有人能给我指个方向吗?

$(document).ready(function() {
  $('.gallery-column img').on('click', function() {
    var expandImg = document.getElementById("expandedImg");
    expandImg.src = this.src;
    expandImg.parentElement.style.display = "block";
  });
});

* {
  box-sizing: border-box;
}

.gallery-wrap {
  width: 50%;
  height: 1066px;
  margin: 0 auto;
  display: flex;
}

.gallery-row {
  width: 52%;
  max-height: 497px;
}

.gallery-column {
  position: relative;
  padding: 10px;
}

.img-caption {
  position: absolute;
  bottom: 10%;
}

.gallery-column img {
  width: 100%;
  opacity: 0.8;
  cursor: pointer;
}

.gallery-column img:hover {
  opacity: 1;
}

.gallery-container {
  position: relative;
  width: 90%;
  height: 500px;
}

#expandedImg {
  width: 100%;
  height: 100%;
}

只需添加下面的代码,你的图像点击功能。

var _caption = $(this).next("div").html();
$("#expandedImgCaption").html(_caption);

expandedImgCaption 是扩展图像的标题ID

代码片段:

$(document).ready(function() {
  $('.gallery-column img').on('click', function() {
    var expandImg = document.getElementById("expandedImg");
    expandImg.src = this.src;
    expandImg.parentElement.style.display = "block";
    var _caption = $(this).next("div").html();
    $("#expandedImgCaption").html(_caption);
  });
});

* {
  box-sizing: border-box;
}

.gallery-wrap {
  width: 50%;
  height: 1066px;
  margin: 0 auto;
  display: flex;
}

.gallery-row {
  width: 52%;
  max-height: 497px;
}

.gallery-column {
  position: relative;
  padding: 10px;
}

.img-caption {
  position: absolute;
  bottom: 10%;
}

.gallery-column img {
  width: 100%;
  opacity: 0.8;
  cursor: pointer;
}

.gallery-column img:hover {
  opacity: 1;
}

.gallery-container {
  position: relative;
  width: 90%;
  height: 500px;
}

#expandedImg {
  width: 100%;
  height: 100%;

这个按预期工作

$(document).ready(function() {
  $('.gallery-column').on('click', function() {
    var expandImg = document.getElementById("hoc");
    expandImg.replaceChild(this, expandImg.childNodes[0])
  });
});

您可以将其转换为jquery插件并删除ID。这样,您就可以在一个页面上拥有各种库。我会瞄准 img 和 .img-caption 选择器并修改它们的属性。

(function($) {
  $.fn.child = function(s) {
      return $(this).children(s).first();
  };
  $.fn.gallery = function() {
    var $this = this;
    $this.find('.gallery-column').on('click', function(e) {
      var $container = $this.find('.gallery-container');
      $container.child('.gallery-display').prop('src', $(this).child('img').prop('src'));
      $container.child('.img-caption').html($(this).child('.img-caption').html());
    });
    return $this;
  };
})(jQuery);

$(document).ready(function() {
  $('.gallery-wrap').gallery(); // Convert to gallery.
});

* {
  box-sizing: border-box;
}

.gallery-wrap {
  width: 75%;
  height: 1066px;
  margin: 0 auto;
  display: flex;
}

.gallery-row {
  width: 52%;
  max-height: 497px;
}

.gallery-column {
  position: relative;
  padding: 10px;
}

.img-caption {
  position: absolute;
  margin: 0 2%; /* Added padding to the left and right */
  bottom: 10%;
}

.gallery-column img {
  width: 100%;
  opacity: 0.8;
  cursor: pointer;
}

.gallery-column img:hover {
  opacity: 1;
}

.gallery-container {
  display: block;
  position: relative;
  width: 90%;
  height: 500px;
}

.gallery-display {
  width: 100%;
  height: 100%;
