用于NOWRAP的javascript replace（）方法和脚本

Question

I have a problem , this is fixed code that I can't change manually. The question is if it possible with JavaScript replace the actual text inside code??

  <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>

Any Ideas???

Answer 1

Judging by given markup, following JS code should make the replacement:

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