Answer 1

您可以执行以下操作

Array.from(document.getElementsByClassName('ITSn')).forEach(element => {
element.innerText += ': ' + element.nextElementSibling.innerText;
   element.nextElementSibling.remove();
});

<div id="HTML_SPEC"
 class="ITSs">
<div class="ITSg">Specifications</div>
<div class="ITSr0">
    <div class="ITSn">Battery form</div> 
    <div class="ITSv">Cylinder</div>
</div>
<div class="ITSg">Batterie</div>
<div class="ITSr0">
    <div class="ITSn">battery voltage</div> 
    <div class="ITSv">1,5 V</div>
</div>
<div class="ITSr1">
    <div class="ITSn">Capacity</div> 
    <div class="ITSv">7800 mAh</div>
</div>
