我有一个问题，这是我无法手动更改的固定代码。问题是是否可以用 JavaScript 替换代码中的实际文本？

  <td nowrap="nowrap">Код безопасности<span class="myWinError">*</span>:</td>

    <div class="myBtnCont x-unselectable" unselectable="on" id="subbutmyAdvF3" onclick="document.getElementById('submmyAdvF3').click();"><a href="javascript://" onclick="return false;">Отправить</a></div>

有任何想法吗？？？

这是这些元素所在的实际弹出框

<div id="_uwndWnd1" class="xw-plain x-unselectable xw-resize xw-active" unselectable="on" style="position: absolute; width: 400px; z-index: 2; left: 0px; overflow: visible;"><div class="xw-disabled" style="overflow: hidden; position: absolute; z-index: 30010; width: 400px; height: 168px; display: none;" unselectable="on"></div><div class="xw-tl" unselectable="on"><div class="xw-tr" unselectable="on"><div class="xw-tc" unselectable="on"><div class="xw-sps" unselectable="on"></div><div class="xw-hdr xw-draggable" unselectable="on"><div class="xt xt-close xt-close2" unselectable="on"></div><div class="xt xt-maxi" unselectable="on" style="display: none;"></div><div class="xt xt-rest" unselectable="on" style="display: none;"></div><div class="xt xt-mini" unselectable="on" style="display: none;"></div><span class="xw-hdr-text" unselectable="on" title="">Užsakyti kuponas</span></div></div></div></div><div class="xw-ml" unselectable="on"><div class="xw-mr" unselectable="on"><div class="xw-mc" unselectable="on"><div class="xw-body" unselectable="on"><div style="overflow: hidden; height: 127px;" unselectable="on"><div class="myWinCont" style="display: none; overflow: hidden;" align="left" unselectable="on"><div align="left" unselectable="on"><div class="myWinLoad" unselectable="on"></div></div></div><div class="myWinCont" style="overflow: auto; width: 378px; display: block; height: 100%;" align="left" unselectable="on">

从给定的标记来看，下面的 JS 代码应该进行替换：

<script>
    document.getElementsByClassName("myWinError")[1].parentNode.innerHTML = 'Кот Шредингера <span class="myWinError">*</span>';
    document.getElementsByClassName("myBtnCont")[0].firstChild.innerHTML = 'Заправить';
</script>
