如果字段留空，如何不显示glyphicon-ok？

Question

我有一个＆＃34; txtPhone＆＃34;输入过滤器不是必需的，但只能接受电话号码，所以：

let text = textField.text
let newText = String(text.characters.first!).capitalizedString + String(text.characters.dropFirst())

Bootstrap验证

 <label class="control-label">Phone</label>
<input type="text" id="txtPhone" class="form-control intonly" maxlength="12" placeholder="Phone" name="Phone">

但是当我点击文本框中显示的提交按钮时。

  Bootstrap Validation

     Phone: {
                     enabled: false,
                    validators: {
                        regexp: {
                            regexp: /^((091|\+91)?|\((091|\+91)?\)|(91)?|\(91\)|0)? ?[7-9][0-9]{9}$/,
                            message: 'The Indian Phone No must contain 10 digits'
                        },

                    }
                },


        .on('keyup', '[name="Phone"]', function () {
                var isEmpty = $(this).val() == '';
                $('#form1')
                       .formValidation('enableFieldValidators', 'Phone', !isEmpty);
                // Revalidate the field when user start typing in the Phone field
                if ($(this).val().length == 1) {
                    $('#form1').formValidation('validateField', 'Phone')
                }
            })
