bootstrapValidator自定验证方法写法

//表单验证issueInvoiceForm.validation = function(){ $('#issueInvoiceForm').on('init.field.bv', function(e, data) {    var $icon   = data.element.data('bv.icon'),      options  = data.bv.getOptions(),           // Entire options      validators = data.bv.getOptions(data.field).validators; // The field validators    if (validators.notEmpty && options.feedbackIcons && options.feedbackIcons.required) {     $icon.addClass(options.feedbackIcons.required).show();    }  }).bootstrapValidator({    container:'popover', feedbackIcons: {  required: 'glyphicon glyphicon-asterisk requiredStar',      valid: 'glyphicon glyphicon-ok',      invalid: 'glyphicon glyphicon-remove',      validating: 'glyphicon glyphicon-refresh'    },    fields: {     invoiceDate:{validators: {notEmpty: {message: '开票日期不能为空'}}},//开票日期     code:{validators: {notEmpty: {message: '发票编码不能为空'}}},     amount:{     validators:{      notEmpty: {message: '发票金额不能为空'},      numeric: {message: '发票金额只能输入数字'},      callback: {             message: '开票金额小于选中金额',             callback: function(value, validator) {              return false;             }           }     }     },     taxRate:{     validators:{      notEmpty: {message: '税率不能为空'},      numeric: {message: '税率只能输入数字'}     }     },     taxAmount:{     validators:{      notEmpty: {message: '税额不能为空'},      numeric: {message: '税额只能输入数字'}     }     },    },group:'.validateDiv' }).on('success.form.bv', issueInvoiceForm.issueInvoiceFormBtn).on('error.form.bv',function(){  $("#issueInvoiceFormBtn").removeAttr("disabled");//将保存按钮去除disabled   $(".has-error:visible:first").find(":input").focus();  });};
