Common validation in the Jquery Easyui framework

For Validatebox space, verify that the maximum value of its input character length exceeds the field length set in the database. Here's how:

1 /**2 * Verify input character length3 */4 $.extend ($.fn.validatebox.defaults.rules, {5 maxLength: {6Validatorfunction(value, param) {7 if(Value.length >= param[0]) {8 //showmsg ("Input information length must not exceed" + param[0] + "characters", 0,-1);9 if($ ("#owner"). Validatebox ("GetValue"). Length > Param[0]) {Ten$ ("#owner"). Validatebox ("SetValue", "" "); One } A return false; - } - //return value.length <= param[0]; the },  -Message: " - } -});

The label settings on the JSP page are as follows:

1  <  ID= "owner"2  class= "Easyui-validatebox"3  Invalidmessage= "cannot exceed 30 characters!" "4  data-options=" Autowidth:true,required:true,5  Validtype : ' maxlength[30] '>
