如何使用javascript制作动态更改的下载链接？

我正在制作Flash画廊网站,我希望页面底部的文字成为Flash的下载链接.此文本更改为当前正在显示的当前Flash的标题.我希望href标记可以动态更改,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.这是我第一次玩下载链接,更不用说那些随变量动态变化的下载链接了.简而言之,我希望链接更改为links数组中存在的文件路径.

包含我的动态链接起始代码的函数称为DOWNLOAD

的HTML

<body>

    <div id="titleText">
        <h1>Anon Curb</h1>
    </div>
    <div id="flashmovie">
        <object type="application/x-shockwave-flash" data="swfs/welcomeflash.swf">'+
            <param name="movie" value="swfs/welcomeflash.swf">
        </object>
    </div>
    <!-- end #container -->
    <div id="buttonCon">

        <div id="buttons">
            <button id="next">next</button>

            <button id="rand">Random</button>

            <button id="back">Back</button>
        </div>

    </div>

    <div id="titleCon">
        <a href="#" id="downLink">
        <div id="title">Hit random button</div>
        </a>
    </div>
    <!-- end #wrapper -->

    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-beta1/jquery.min.js"></script>
    <script src="js/flashcollection.js"></script>
</body>

JAVASCRIPT

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

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

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

    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('rand', 'back', 'next').onclick = function () {
            document.getElementById('downlink').attr("href", links[c]);
        }
    }

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

解决方法:

正确的JavaScript

它使用Soltani Neji的编辑下载功能以及用于更改下载属性的标签,如果没有该属性,该属性将无法使用.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);
});
