在生成链接的HTML时,可以通过在target
中指定iframe的名称来获取它。
所以在你的iframe中添加一个name
属性,如下所示:
<iframe id="iframe" name="iframe" src="mylink" width="100%" height="400"></iframe>
然后添加一个target
属性。
document.getElementById('mylink').innerHTML = '<a href="' + link[intlinkIndex] + '" target="iframe">' + link[intlinkIndex] + '</a>';
function writeLink() { if (intlinkIndex >= link.length) { let btn = document.getElementById('btn'); btn.style.display = 'none'; mylink.style.display = 'none'; } document.getElementById('mylink').innerHTML = '<a href="' + link[intlinkIndex] + '">' + link[intlinkIndex] + '</a>'; document.getElementById('iframe').src = link[intlinkIndex]; intlinkIndex++; }
