Java软件小白通过本文主要向大家介绍了bootstrapvalidator,jsp syntax validator,validator,hibernate validator,formvalidator等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
效果图：
如图，这是使用Validator插件，所完成的功能，效果很强大，也很方便，这边推荐使用这种方式，最后介绍一下原始js验证写法。
首先，导入插件：
<link href="<%=basePath %>bootstrap/css/bootstrap-datetimepicker.min.css" rel="external nofollow" rel="stylesheet" media="screen"></div>
<script src="<%=basePath %>bootstrap/js/bootstrapValidator.min.js"></script> <script src="<%=basePath %>bootstrap/js/bootstrapValidator.zh_CN.js"></script> bootstrapvalidator源码：https://github.com/nghuuphuoc/bootstrapvalidator boostrapvalidator api：http://bv.doc.javake.cn/api/</div>
jsp：

我这边没有使用表单提交验证，而已点击button按钮，Ajax提交，注意一下。
js：
$(function(){/* 文档加载，执行一个函数*/
// $(".submit_review").attr({"disabled":"disabled"});
$('#defaultForm').bootstrapValidator({
message: 'This value is not valid',
feedbackIcons: {/*输入框不同状态，显示图片的样式*/
valid: 'glyphicon glyphicon-ok',
invalid: 'glyphicon glyphicon-remove',
validating: 'glyphicon glyphicon-refresh'
},
fields: {/*验证*/
company_name: {/*键名username和input name值对应*/
validators: {
notEmpty: {/*非空提示*/
message: '公司名称不能为空'
},
// stringLength: {/*长度提示*/
// min: 6,
// max: 30,
// message: '用户名在6到30之间'
// }/*最后一个没有逗号*/
}
},
company_id: {
validators: {
notEmpty: {
message: '公司ID不能为空'
},
}
},
equipment_ip: {
validators: {
notEmpty: {
message: '设备IP不能为空'
},
regexp: {
regexp: /^(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])$/,
message: '设备IP不合法'
}
}
},
}
})
});
</div>
$("#btn_reset").click(function(event) {
/* Act on the event */
$('#defaultForm').data('bootstrapValidator').resetForm(true);
});
$("body").on('click', '#btn_submit_add', function(event) {
/* Act on the event */
$('#defaultForm').bootstrapValidator('validate');
var flag = $("#defaultForm").data('bootstrapValidator').isValid();
if (!flag) {
toastr.error("填写有误，请重新填写！");
} else {
$.post('addEquipmentInfoCheck.action', {
"equipmentInfoCheck.companyId": $("#company_id").val(),
"equipmentInfoCheck.companyName": $("#company_name").val(),
"equipmentInfoCheck.machineRoom": $("#computer_room").val(),
"equipmentInfoCheck.equipmentCabinet": $("#cabinet").val(),
