选择其他分区

Question

<div id="random numbers"> 
<div class="column-1"><a href="..."></a></div> 
<div class="column-1"><a href="...">this value I want to change</a></div> 
<div class="column-1"><a href="..."></a></div> 
</div> 

内每2格从早期的建议，我有这样的代码：

var elements = document.querySelectorAll('.column-1 a'); 
for (var i = 0; i < elements.length; i++) { 
    elements[i].outerHTML = "OVERRIDDEN"; 
    } 

我遇到的问题是，这种替换每个<a每个格<div id="random numbers">）里面，虽然我喜欢它只是为了替换每个随机数div中的第二列-1。

谢谢你提前！

Answer 1

document.querySelectorAll（'。column-1 a'）[1] .outerHTML =“OVERRIDDEN”;

Answer 2

i与

var elements = document.querySelectorAll('.column-1'); 
for (var i = 0; i < elements.length; i++) { 
    if(i%2) { // override 2nd, 4th, etc. 
    elements[i].outerHTML = "OVERRIDDEN"; 
    } 
}
