我开始研究可访问性.aria-labelledby和aria-describe在Chrome和Firefox中运行良好,但在IE浏览器中没有被NVDA正确阅读.
<div id="div1">div 1</div>
<div id="div2">div 2</div>
<div>div 3</div>
<button aria-labelledby="div1 div2 buttonName1"><span id="buttonName1">Test1</span></button>
<br>
<button aria-describedby="div1 div2 buttonName2"><span id="buttonName2">Test2</span></button>
