如何使用 javascript 进行动态变化的下载 link？

Question

我正在制作一个 Flash 画廊网站，我希望页面底部的文字是 Flash 的下载 link。此文本更改为当前正在显示的当前 Flash 的标题。我希望 href 标签动态更改以匹配正在播放的特定 Flash 的文件路径，以便用户可以下载它。这是我第一次尝试下载 links，更不用说那些随变量动态变化的下载了。所以简而言之，我希望 link 更改为 links 数组中存在的文件路径。

包含我的动态 links 起始代码的函数称为 DOWNLOAD

HTML

嗨，我很喜欢，这对我有用对于 HTML 文件，你只需要添加第一张图片的 href，因为文件总是在他启动时加载第一张图片，你还需要将属性下载添加到标签中，所以这就像

<div id="titleCon">

    <a href="unknittingmouse1.swf" id="downLink" download="">
    <div id="title">Hit random button</div>
    </a>
</div>

对于javascript，您需要像这样编辑下载函数然后在每个按钮点击事件中调用它，像这样：

$(document).ready(function () {
    var links = [
'swfs/#1%20(Special%20Japanese%20Extended%20Dance%20Mix).swf',
'swfs/$D6.swf',
'swfs/(MAD)%20Huh.swf'
];

 var displaytext = [
'#1 (Special Japanese Extended Dance Mix)',
'$D6',
'(MAD) Huh'
];

var c = 0
    var flashmovie, test, temp;

    function init() {
        flashmovie = document.getElementById('flashmovie');
        document.getElementById('back').onclick = function () {
            if (c == 0) {
                c = links.length;
            }
            c--
            displayFiles();
            download();
        }

        document.getElementById('next').onclick = function () {
            if (c == links.length - 1) {
                c = -1;
            }
            c++;
            displayFiles();
            download();
        }

        document.getElementById('rand').onclick = function () {
            temp = c;
            while (c == temp) {
                c = Math.floor(Math.random() * links.length);
            }
            displayFiles();
            download();
        }
    }

    function displayFiles() {

        test = links[c].substring(links[c].lastIndexOf('.') + 1, links[c].length);
        document.getElementById('title').innerHTML = displaytext[c];

        flashmovie.innerHTML =
            '<object type="application/x-shockwave-flash" data="' + links[c] + '">' +
            '<param name="movie" value="' + links[c] + '">' +
            '<\/object>';
    }

    function download() {

            document.getElementById('downLink').setAttribute('href', links[c]);
        }


    window.addEventListener ?
        window.addEventListener('load', init, false) :
        window.attachEvent('onload', init);
});`

希望对您有所帮助:)

正确的javascript

这使用了 Soltani Neji 的编辑下载功能以及更改下载属性的标签，没有它就无法工作。不过不知道这对我来说是正常还是特殊

var c = 0;
    var flashmovie, test, temp;

    function init() {
        flashmovie = document.getElementById('flashmovie');
        document.getElementById('back').onclick = function () {
            if (c == 0) {
                c = links.length;
            }
            c--
            displayFiles();
            download();
        }

        document.getElementById('next').onclick = function () {
            if (c == links.length - 1) {
                c = -1;
            }
            c++;
            displayFiles();
            download();
        }

        document.getElementById('rand').onclick = function () {
            temp = c;
            while (c == temp) {
                c = Math.floor(Math.random() * links.length);
            }
            displayFiles();
            download();
        }

    }

    function displayFiles() {

        test = links[c].substring(links[c].lastIndexOf('.') + 1, links[c].length);
        document.getElementById('title').innerHTML = displaytext[c];

        flashmovie.innerHTML =
            '<object type="application/x-shockwave-flash" data="' + links[c] + '">' +
            '<param name="movie" value="' + links[c] + '">' +
            '<\/object>';
    }

    function download() {
        document.getElementById('downLink').setAttribute('href', links[c]);
        document.getElementById('downLink').setAttribute('download', displaytext[c]);
    }

    window.addEventListener ?
        window.addEventListener('load', init, false) :
        window.attachEvent('onload', init);
});
