推荐答案

function getSearchUniversity() {
  country = jQuery('[name=countryKey]').val();
  state = jQuery('[name=stateKey]').val();
  level= jQuery('[name=level]').val();
  degType= jQuery('[name=degType]').val();
  jQuery.ajax({
    type: "POST",
    url:baseurl+ 'welcome/searchUnivtab', 
    cache: false,
    data: {countryKey: country, stateKey: state, level: level, degType: degType},
    error: function()
    {
      //notify('Error: Your request could be processed.. try again..!!');
    },
    success: function(html)
    {
      jQuery('[name=universityList]').html(html);
      return false;
    }
  }); 
}
