我可以从JavaScript设置渲染属性的值吗？

Question

我可以从JavaScript设置h:commandLink rendered属性的值吗？

<h:commandLink id="profileLink" rendered="#{bean.enable}">

Answer 1

No. The rendered attribute is for the server side, not for the client side. In plain HTML/JS in the client cide you can just toggle the CSS display property.

// Get element by client ID.
var element = document.getElementById('formid:buttonid');

// Hide it.
element.style.display = 'none';

// Show it.
element.style.display = 'inline'; // or 'block' if it's a HTML block element
