字体超值提交按钮

Question

I would like display a font awesome icon as the submit input value. I tried the following code as per this SO question Font-awesome, input type 'submit'

Demo http://jsfiddle.net/sw87W/1077/

$(document).ready(function() {
  $('.btn-primary').val('');
});

I do not have any control over the html that is generated, therefore I can not change the input to a button

您可以只使用Unicode转义序列 ：

$('.btn-primary').val('\uf0c7');
