If the text area which your are trying to bind focus to is loaded dynamically [using ajax or something], then you have to bind the live event of focus. Something like this
如果您尝试将焦点绑定到的文本区域是动态加载的 [使用 ajax 或其他东西]，那么您必须绑定焦点的实时事件。像这样的东西
$('#status').live('focus', function() {
alert('focused!');
});
});

Your jquery is written correctly. See this similar fiddle. Check with a debugger (in Chrome or Firebug), is the focusmethod being called? You can try putting the code in a $('document').ready()function.
您的 jquery 编写正确。看到这个类似的小提琴。检查调试器（在 Chrome 或 Firebug 中），是否focus正在调用该方法？您可以尝试将代码放入$('document').ready()函数中。
<textarea id="status" placeholder="Write here..." name="new_entry"></textarea>
<textarea id="status2" placeholder="Write here..." name="new_entry"></textarea>
$('#status').focus(function() {
$('#status2').val("wheee");
});
