请问jq easyui validatebox怎么判断是否重复

[Leo201228]

field:'id_card',
title:'身份证',
width:140,
editor:{
type:'validatebox',
options:{
required:true,
},
},
就是检查数据库里是否有重复的值，一旦重复报错

有个remote配置就是远程检查的，第一个参数url，第二个是发送这个input值的键名称。看API视乎是这样，remote没有详细说明。如果没用自己定义一个规则，用ajax同步请求服务器获取是否重复信息在return true/false 自己看validatebox的api：http://www.jeasyui.com/documentation/index.php validType string,array Defines the field valid type, such as email, url, etc. Possible values are: 1) a valid type string, apply a single validate rule. 2) a valid type array, apply multiple validate rules. The multiple validate rules on a field are available since version 1.3.2. 3) a key/value pairs, the key is the validing type name, the value is an array consisting validating parameters. Code example: <input class="easyui-validatebox" data-options="required:true,validType:'url'"> <input class="easyui-validatebox" data-options=" required:true, validType:['email','length[0,20]'] "> <input class="easyui-validatebox" data-options=" required:true, validType:{ length:[10,30], remote:['http://.../action.do','paramName'] } ">
