jquery实现ajax提交表单信息的简单方法(推荐)

; (function ($) { 
 
  $.fn.ajaxForm = function (options) { 
    var defaults = { 
      modelname: 'model',//后台对象接收名称 
      url: '/',//提交地址 
      postType: 'POST',//提交方式 
      dataType: 'JSON',//数据返回类型 
      async: false,//是否异步 
      optionObj: [],//自定义参数 
      callback: function () { },//成功回调 
    }; 
    var options = $.extend(defaults, options);//合并参数 
 
    if (options.url == '') { 
      alert('请填写提交地址'); 
      return; 
    } 
    var postvals = {}; 
 
    //textbox/隐藏域/textarea/radio选中值 
    $(this).find('input[type="text"],input[type="hidden"],textarea,input[type="radio"]:checked').each(function () { 
      if ($(this).val() != undefined) { 
        var name = $(this).attr('name'); 
        if (name == undefined || name == '') { 
          return false; 
        } 
        var value = $(this).val(); 
        var json = '{"' + name + '":"' + value + '"}'; 
        var obj = $.parseJSON(json); 
        postvals = $.extend(postvals, obj); 
      } 
    }); 
 
    var resObj; 
    if (options.optionObj != undefined || options.optionObj!=[]) { 
      resObj = $.extend(postvals,options.optionObj); 
    } else { 
      resObj = postvals; 
    } 
 
    $.ajax({ 
      type: options.postType, 
      dataType: options.dataType, 
      data: resObj, 
      async: options.async, 
      url: options.url, 
      success: function (json) { 
        if (json.IsError) { 
          alert(json.Message); 
        } else { 
          options.callback(); 
        } 
      } 
    }); 
  }; 
 
})(jQuery);
