title: Input validation message toggle for blur and focusIn
body: <p>I want to trigger the validation only for input "blur" instead of typing on it. So I have used the method <code>validateTrigger:'onBlur'</code> and its worked fine for me as expected. After user focus/click again the input, the validation message should disappear, any solution?</p>
  
  <pre><code>&lt;FormItem&gt;
  {getFieldDecorator('email', {
      rules: [
          {
            type: 'email', message: 'Valid E-mail required!',
          },
          { required: true, message: 'E-mail required!', whitespace:true }
      ],
      validateTrigger:'onBlur'
  })(
      &lt;Input
          placeholder="Email"
      /&gt;
  )}
  </code></pre>
  
  <p></p>
