Question

我是JavaScript的新手，并试图想出如何将Alt属性添加到数组中。这是我到目前为止所拥有的。我该如何在哪里添加？我正在考虑在body / table中添加alt ='“但显然这不起作用。

<script type="text/javascript">

        var pictures = new Array();
        pictures[0] = new Image();
        pictures[0].src = "image.jpg";
        pictures[1] = new Image();
        pictures[1].src = "image2.jpg";



<body>
    var x = "<table>";
        for (var y=0; y<rows; y++) {
            x += "<tr> ";
            for (var j=0; j<columns; j++) {
                var ix = (y * rows + j) % pictures.length;
                var id = y + "-" + j;

                x += "<td> <img src=' " + pictures[ix].src + 
                     "' " +
                     " id='" + id + "' " +
                     " height='300' width='300' ></td>";

＆＃34; Alt和＃34;如果图像无法正确显示，则属性中的文本将显示。

                     x += "<td> <img src=' " + pictures[ix].src + 
                     "' " +
                     " id='" + id + "' " +
                     " height='300' width='300' alt='image_" + j + "'  ></td>";
