从HTML页面在模态窗口中显示图像

时间：2017-01-23 18:31:51

标签： javascript html css

在我的HTML中，我有几篇文章。每篇文章都包含一个图像，如果单击其中一个图像，则会出现一个模态窗口。所以我的问题是，如何从模态窗口中显示文章中的图像？

如果您想检查我的代码，请检查：

＆＃13;
＆＃13; 
 var article = document.querySelectorAll("article");
    var modal = document.querySelector(".modal");
    var cross = document.querySelector(".cross");
    var contentModal = document.querySelector(".modal .contentModal img");
    var image = document.querySelectorAll("article img");

    var funcModal = function (value) {
        article[value].addEventListener("click", function () {
            modal.style.visibility = "visible";
            modal.style.opacity = "1";
            contentModal.style.src = image;
        })
        cross.addEventListener("click", function () {
            modal.style.visibility = "hidden";
            modal.style.opacity = "0";
            modal.style.transition = "opacity 1s";
        })
    }

    for(var i = 0; i < article.length; i++) {
        funcModal(i);
    }

现在，您要在点击任何内容之前设置image变量一次（并将其设置为图像列表）。您希望每次单击文章时将该变量设置为所单击文章的图像。

var article = document.querySelectorAll("article");
    var modal = document.querySelector(".modal");
    var modalImage = modal.querySelector('img');
    var cross = document.querySelector(".cross");

    var funcModal = function(value) {
      article[value].addEventListener("click", function() {
        modal.style.visibility = "visible";
        modal.style.opacity = "1";
        // here, "this" will be a reference to the article clicked
        var image = this.querySelector('img');
        modalImage.src = image.src;
      })
      cross.addEventListener("click", function() {
        modal.style.visibility = "hidden";
        modal.style.opacity = "0";
        modal.style.transition = "opacity 1s";
      })
    }

    for (var i = 0; i < article.length; i++) {
      funcModal(i);
    }
