我有一个简单的HTML结构与div元素.我想在div每个父级的子节点中找到值的总和div,但前提是父节点至少有三个子节点.
这就是我尝试过的,但它得到了每个div的总和:
var sum = 0;
$("div > div > div").each(function () {
sum += parseInt($(this).text(), 10);
});
console.log(sum);<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
<div>
<!-- want to calculate this --->
<div>1</div>
<div>1</div>
<div>1</div>
<div>1</div>
</div>
<div>
<!-- don't want to calculate this --->
<div>1</div>
<div>1</div>
<div>1</div>
</div>
<div>
<!-- want to calculate this --->
<div>1</div>
<div>1</div>
<div>1</div>
<div>1</div>
</div>
</div>所以在上面的例子中,我打印答案8.
