How to enable a disabled button by clicking on another button?
提问by user2565280
I have two buttons:
我有两个按钮：
<button onclick=initialize() id="1" data-role="button" data-mini="true" data-corners="false" data-theme="b">Show My Position</button>
<button onclick=calcRoute() id="2" data-role="button" data-mini="true" data-corners="false" data-theme="b">Evacuate !</button>
I want to have the second button disabled by default, and have it enabled if clicking on the first button. How do I accomplish this?
我想默认禁用第二个按钮，并在单击第一个按钮时启用它。我该如何实现？
