numberbox remote Question

[fen9ye]

My code is like this:
<input type="text" class="easyui-numberbox" name="candNum"
            data-options="
               min:0,
               max:99999,
               required:true,
               validType:{
                  length:[1,5],
                  remote:['info_validateCandNum.action','candNum']
               },
               delay:400,
               formatter:function(value){
                  var str = value.toString();
                  while(str.length<5){
                     str = '0'+str;
                  }
                  return str;
               }
            ">
the server side can get the param,and will return 'true' at last
 PrintWriter out = response.getWriter();
 out.println("true");
however,the numberbox is still in the invalid state.Can anyone solve my problem?

When I turn out.println("true") to out.print("true"),it works,I don't know why.

The 'remote' validation is defined as:

Code:

$.extend($.fn.validatebox.defaults.rules,{
	remote: {
		validator: function(value, param){
			var data = {};
			data[param[1]] = value;
			var response = $.ajax({
				url:param[0],
				dataType:'json',
				data:data,
				async:false,
				cache:false,
				type:'post'
			}).responseText;
			return response == 'true';
		},
		message: 'Please fix this field.'
	}
})

It requires the server to return the 'true' string with no "\n" character.

can be original fixed to:

Code:

}).responseText;
return response.replace(/\s/g, '') == 'true';
