使用Javascriipt循环更改数据内容

Question

I have this code:

<div>
<a href="#sizes" title="Select a Size" data-href="#sizes" class="size_selected" data-content="10.0">
</div>

I am trying to change the data-content using javascript. But i want the code to loop until the data-Content changes.

Answer 1

您可以使用dataset属性设置data属性：

<a id="my-link" href="#sizes" title="Select a Size" data-href="#sizes" class="size_selected" data-content="10.0">

document.getElementById('my-link').dataset.content = "5.0";
