Bootstrap 所需的验证程序文件名在应该验证时不会失败

Question

我正在使用验证器插件来验证我的表单。我有一个简单的表单，只有一个输入框，type=file。

我已经设置了一个规则，我认为该规则将表单字段设置为必填。当加载表单时，我在没有输入文件名或浏览到文件的情况下单击“提交”按钮，表单得到验证。

我需要表单验证失败并生成一条错误消息，指出需要选择一个文件。

非常感谢任何帮助。

Answer 1

首先你不需要 rule

rules: {
    uploadfile: {
        required: true
    }
},

其次，你必须设置notEmpty以便bootstrapValidator检查文件输入

notEmpty: {
  message: 'You must select a valid payroll file to upload'
},

第三，你必须为 extensions 设置 type，在你的情况下，文件扩展名是 'txt,xls,csv', ，而且我认为 csv 不受支持，你可能需要自定义它的验证规则。（见底部的编辑）

BootstrapValidator Supported file formats

$(document).ready(function () {
    $('#contactForm').bootstrapValidator({
      container: '#messages',
      feedbackIcons: {
        valid: 'glyphicon glyphicon-ok',
        invalid: 'glyphicon glyphicon-remove',
        validating: 'glyphicon glyphicon-refresh'
      },
      fields: {
        uploadfile: {
          validators: {
            notEmpty: {
              message: 'You must select a valid payroll file to upload'
            },
            file: {
              extension: 'txt,xls,csv',
              type: 'text/plain,application/vnd.ms-excel,text/csv'
            }
          }
        }
      }
    });
});

编辑： 您可以将 csv 扩展验证为类型“text/csv”，无需自定义验证。
