Question

伙计所以我有12个段落，我需要做的是当我点击它时，文本必须加倍（元素加倍），基本上行数必须加倍，事情是当段落有1000个元素，它不能加倍。好的，我在这里有我的HTML代码：

<div id="pastraipos">
<p>is simply dummy text of the printing and typesetting industry. </p>
<p>it is a long established fact that a reader will be distracted.</p>
<p>There are many variations of passages of Lorem Ipsum available.</p>
<p>is simply dummy text of the printing and typesetting industry. </p>
<p>is simply dummy text of the printing and typesetting industry. </p>
<p>is simply dummy text of the printing and typesetting industry. </p>
<p>is simply dummy text of the printing and typesetting industry. </p>
<p>is simply dummy text of the printing and typesetting industry. </p>
<p>is simply dummy text of the printing and typesetting industry. </p>
<p>is simply dummy text of the printing and typesetting industry. </p>
<p>is simply dummy text of the printing and typesetting industry. </p>
<p>is simply dummy text of the printing and typesetting industry. </p>
</div>

所以我理解我需要事件，并循环该事件监听器，所以我可以对所有段落产生相同的效果。

var lala = document.getElementById('pastraipos');
var lala1 = lala.childElementCount;

function F2(){
    for (i = 0; i < lala1; i++){
    var cln = lala.children[i].cloneNode(true);
    lala.appendChild(cln)[i+1];
  }
}

for (var k = 0; k < lala1; k++) {
            lala.children[k].addEventListener('click', F2, false);
}

它使所有段落加倍的问题，并且无法弄清楚段落中有1000个元素（空间计数），感谢您的帮助！
