Question

我有一大块盒子。每个方框打开一个模态。每个模态都有图像。

问题是页面加载所有图像并且它需要永远。如何在打开特定模态时才能加载模态图像？也许还有一个spinner gif？

我正在使用 custombox.js 插件。

$(document).ready(function() {
    $('.info').on('click', function(e) {
        Custombox.open({
            target: $(this).data('href'),
            effect: 'push',
            speed: 500,
            overlayColor: '#2C3E50',
            overlayClose: false,
            //overlayEffect: '',
            //overlayOpacity: 1,
        });
        e.preventDefault();
    });
});

编辑：示例模态代码

    <div id="portfolioItemClose" class="close"><span></span>

    <div class="portfolioTitle wow fadeInLeft" data-wow-delay=".5s" data-wow-duration=".3s">ikuw solutions

解决方案是在加载时删除所有模态框图像源，并将其值保存在属性data-src中。然后，当您打开模态窗口时，由于相应的data-src值，您可以将源设置为仅打开的模态图像。这样的事情：

$(document).ready(function () {
    // Considering that your modal divs have a class 'modal'
    $(".modal img").not(":visible").each(function () {
        $(this).data("src", this.src);
        this.src = "";
        // or remove the whole attribute with $(this).removeAttr("src")
    });

    // Set an attribute `data-sourcesAreSet` to each modal div in order to prevent setting the images sources if they are already set
    $(".modal").each(function () {
        $(this).data("sourcesAreSet", false);
    });

    $('.info').on('click', function (e) {

        var correspondingModal = $($(this).data('href'));

        // Only set the images sources if they are not already set.
        if (correspondingModal.data("sourcesAreSet") == false) {
            correspondingModal.find("img").each(function () {
                this.src = $(this).data("src");
                // or add the attribute with $(this).attr("src", $(this).data("src"))
            });
            correspondingModal.data("sourcesAreSet", true);
        }

        Custombox.open({
            target: $(this).data('href'),
            effect: 'push',
            speed: 500,
            overlayColor: '#2C3E50',
            overlayClose: false
        });
        e.preventDefault();
    });
});

以下是可与上述代码一起使用的模式框的示例：

<a data-href="#modal" class="info">Click here</a>

<div id="modal" class="modal-demo modal">
    <button type="button" class="close" onclick="Custombox.close();">
        <span>&times;</span><span class="sr-only">Close</span>
    </button>
    <h4 class="title">Modal title</h4>
    <div class="text">
        Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

如果您还希望在加载图片时显示微调器gif，则可以为每个图像执行建议in this answer的操作，或者，您可以使用带微调器的模态框创建一个div你可以隐藏在自定义框中的gif＆＃34;完成＆＃34;回调函数，虽然我并不完全确定在所有图像加载完毕后触发此函数。

仅在模态打开后加载图像
