为了简单起见,我目前正在使用javascript。如何获取href值并将其存储在javascript变量中。我需要提取每个课程部分的所有属性href值以及每个部分中的每个项目。
<ul class="curriculum-items-list">
<li class="curriculum-section-container ng-scope">
<ul>
<li class="curriculum-item-container ng-scope">
<a href="http://www.mywebsite.com/videoSec1_1.mp4">
</li>
<li class="curriculum-item-container ng-scope">
<a href="http://www.mywebsite.com/videoSec1_2.mp4">
</li>
</ul>
</li>
<li class="curriculum-section-container ng-scope">
<ul>
<li class="curriculum-item-container ng-scope">
<a href="http://www.mywebsite.com/videoSec2_1.mp4">
</li>
<li class="curriculum-item-container ng-scope">
<a href="http://www.mywebsite.com/videoSec2_2.mp4">
</li>
</ul>
</li>
</ul>
渴望结果

您可以使用querySelectorAll
来引用a
元素,然后使用Array.prototype.map
将相关数据提取到数组中:
var hrefs = [].map.call(document.querySelectorAll(".curriculum-item-container a"), function (elem) {
return elem.href;
});
答案 1 :(得分:0)
var hrefs = [];
$(".curriculum-item-container a").each(function (i, a) {
hrefs.push(a.getAttribute("href"));
});

另一种使用 querySelectorAll
获取所有 href 的方法。
let hrefs = [];
document.querySelectorAll('.curriculum-item-container a').forEach(a => {
hrefs.push(a.href);
})
