       onBeforeLoad: function(param){//queryForm' form id
   第一种方案：   

 $($('#queryForm').serializeArray()).each(function(){ 
         param[this.name]=this.value; 
              });

   第二种方案：

    queryParams : getFormJson($("#fm_s")[0]),

    },
    onBeforeSelect:function(){
     return false;
    }

 function getFormJson(form) {
  var o = {};
  var a = $(form).serializeArray();
  $.each(a, function() {
   if (o[this.name] !== undefined) {
    if (!o[this.name].push) {
     o[this.name] = [ o[this.name] ];
    }
    o[this.name].push(this.value || '');
   } else {
    o[this.name] = this.value || '';
