callback 函数可以写自己的方法校验
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(); }); };
remote服务器校验
服务端验证代码(使用spring mvc)如下:
/* * 返回String类型的结果 * 检查用户名的合法性,如果用户已经存在,返回false,否则返回true(返回json数据,格式为{"valid",true}) */ @RequestMapping(value = "/checkNameExistsMethod1", produces = "application/json;charset=UTF-8") public @ResponseBody String checkNameValidMethod1(@RequestParam String name) { boolean result = true; List<Employee> lstEmployees = employeeService.getAllEmployees(); for (Employee employee : lstEmployees) { if (employee.getName().equals(name)) { result = false; break; } } Map<String, Boolean> map = new HashMap<>(); map.put("valid", result); ObjectMapper mapper = new ObjectMapper(); String resultString = ""; try { resultString = mapper.writeValueAsString(map); } catch (JsonProcessingException e) { e.printStackTrace(); } return resultString; }
这里需要说明的是bootstrap的remote验证器需要的返回结果一定是json格式的数据 :
{"valid":false} //表示不合法,验证不通过 {"valid":true} //表示合法,验证通过
如果返回任何其他的值,页面验证将获取不到验证结果导致无法验证。
附一段完整的远程remote验证的代码加说明:
$(function(){/* 文档加载,执行一个函数*/ $('#defaultForm').bootstrapValidator({ message: 'This value is not valid', feedbackIcons: {/*input状态样式图片*/ valid: 'glyphicon glyphicon-ok', invalid: 'glyphicon glyphicon-remove', validating: 'glyphicon glyphicon-refresh' }, fields: {/*验证:规则*/ username: {//验证input项:验证规则 message: 'The username is not valid', validators: { notEmpty: {//非空验证:提示消息 message: '用户名不能为空' }, stringLength: { min: 6, max: 30, message: '用户名长度必须在6到30之间' }, threshold : 6 , //有6字符以上才发送ajax请求,(input中输入一个字符,插件会向服务器发送一次,设置限制,6字符以上才开始) remote: {//ajax验证。server result:{"valid",true or false} 向服务发送当前input name值,获得一个json数据。例表示正确:{"valid",true} url: 'exist2.do',//验证地址 message: '用户已存在',//提示消息 delay : 2000,//每输入一个字符,就发ajax请求,服务器压力还是太大,设置2秒发送一次ajax(默认输入一个字符,提交一次,服务器压力太大) type: 'POST'//请求方式 /**自定义提交数据,默认值提交当前input value * data: function(validator) { return { password: $('[name="passwordNameAttributeInYourForm"]').val(), whatever: $('[name="whateverNameAttributeInYourForm"]').val() }; } */ }, regexp: { regexp: /^[a-zA-Z0-9_\.]+$/, message: '用户名由数字字母下划线和.组成' } } }, password: { message:'密码无效', validators: { notEmpty: { message: '密码不能为空' }, stringLength: { min: 6, max: 30, message: '用户名长度必须在6到30之间' }, identical: {//相同 field: 'password', //需要进行比较的input name值 message: '两次密码不一致' }, different: {//不能和用户名相同 field: 'username',//需要进行比较的input name值 message: '不能和用户名相同' }, regexp: { regexp: /^[a-zA-Z0-9_\.]+$/, message: 'The username can only consist of alphabetical, number, dot and underscore' } } }, repassword: { message: '密码无效', validators: { notEmpty: { message: '用户名不能为空' }, stringLength: { min: 6, max: 30, message: '用户名长度必须在6到30之间' }, identical: {//相同 field: 'password', message: '两次密码不一致' }, different: {//不能和用户名相同 field: 'username', message: '不能和用户名相同' }, regexp: {//匹配规则 regexp: /^[a-zA-Z0-9_\.]+$/, message: 'The username can only consist of alphabetical, number, dot and underscore' } } }, email: { validators: { notEmpty: { message: '邮件不能为空' }, emailAddress: { message: '请输入正确的邮件地址如:123@qq.com' } } }, phone: { message: 'The phone is not valid', validators: { notEmpty: { message: '手机号码不能为空' }, stringLength: { min: 11, max: 11, message: '请输入11位手机号码' }, regexp: { regexp: /^1[3|5|8]{1}[0-9]{9}$/, message: '请输入正确的手机号码' } } }, invite: { message: '邀请码', validators: { notEmpty: { message: '邀请码不能为空' }, stringLength: { min: 8, max: 8, message: '请输入正确长度的邀请码' }, regexp: { regexp: /^[\w]{8}$/, message: '请输入正确的邀请码(包含数字字母)' } } }, } }) .on('success.form.bv', function(e) {//点击提交之后 // Prevent form submission e.preventDefault(); // Get the form instance var $form = $(e.target); // Get the BootstrapValidator instance var bv = $form.data('bootstrapValidator'); // Use Ajax to submit form data 提交至form标签中的action,result自定义 $.post($form.attr('action'), $form.serialize(), function(result) { //do something... }); }); });
