如何使用JavaScript(无JQuery)遍历具有公共类的一堆DIV,然后根据值检查<span>
标记内的值,将href值更改为其他值。这是一个标记示例。
<div class="module-content">
<div class="js-tab-content S00">
<h2 class="heading">
<a href="http://someurl.com">
<span>Adelaide</span>
</a>
</h2>
</div>
<div class="js-tab-content N00">
<h2 class="heading">
<a href="http://anotherurl.com">
<span>Sydney</span>
</a>
</h2>
</div>
<div class="js-tab-content V00">
<h2 class="heading">
<a href="http://thisurl.com">
<span>Melbourne</span>
</a>
</h2>
</div>
</div>

var tabContentDivs = document.getElementsByClassName("js-tab-content");
for (var i = 0, tabContentDiv; tabContentDiv = tabContentDivs[i]; ++i) {
var spanEl = tabContentDiv.querySelector(".heading span");
var spanText = spanEl.innerText;
var aEl = tabContentDiv.querySelector(".heading a");
aEl.href += "#" + spanText; // for example
}

这是:
var divs = document.getElementsByClassName("js-tab-content");
for(var i=0;i<divs.length;i++){
var div = divs[i];
if(!div) break;
var span = div.getElementsByTagName("span");
var link = div.getElementsByTagName("a");
if(span[0].innerHTML == "Adelaide") link[0].href = "http://google.com";
}
