您可以在下面找到代码示例.

    $(function () {
        $("#show_banners").showcase({
            css: {
                "margin-left": "auto",
                "margin-right": "auto"
            },
            animation: {
                type: "fade",
                interval: 4500,
                speed: 1800
            },
            images: [{
                url: "../images/content/example1.jpg",
                description: "example1",
                target: "_self",
                link: ""
            }, {
                url: "../images/content/example2.jpg",
                description: "example2",
                target: "_self",
                link: ""
            }, {
                url: "../images/content/example3.jpg...

DIV的ID是show_banners.

Answer 1

为了从JavaScript中的图像中提取src:

var img_src = document.getElementById('elementId').src;

在jQuery中:

var img_src = $('#elementId').attr('src');

希望有所帮助.
