Hi Varonica

Not sure what you would like to validate, but there are a number of examples in the forums. But here are 3 examples (the temperature validation is similar to number range).

$.extend($.fn.validatebox.defaults.rules, {
   tempRange: {
      validator: function(value, param){
         return (value >= param[0] && value <= param[1]);
      },
      message: 'Temperature must be in the range of {0}°C and {1}°C.'
   },
   numRange: {
      validator: function(value, param){
         return (value >= param[1] && value <= param[2]);
      },
      message: '{0} must be between {1} and {2}.'
   },
   maxLength: {
      validator: function(value, param){
         return value.length <= param[0];
      },
      message: 'Maximum characters allowed is {0}.'
   }
});


This is the html part;
  <input id="minTemp" name="minTemp" class="easyui-validatebox tempVal" required="true" validType="tempRange[-50,70]">
  <input name="tolerance" size="10" class="easyui-validatebox" validType="numRange['Range',0,5000]">
  <textarea name="notes" style="height:80px;width:473px;" class="easyui-validatebox" validType="maxLength[300]"> ></textarea>

Hi Varonica, sorry you right, I did not understand what you meant. I guess what you did want to say was "...but cant find how to extend validtype just for text only!!!!". mzeddd solution only tests the first character, so if the user enters "W8", the function passes. I guess not what you want. You can use RegExp to solve this. You can try the following;

Code:

justText: {  
   validator: function(value, param){  
         return !value.match(/[0-9]/);
   },  
   message: 'Please enter only text.'  
}
