ajax示例

        $.ajax({

                type:"post",

                datatype:"JSON",

                url:"produce.php?c=activitymanage&a=joinerInfo&aid="+aid+"&appid="+appid,

                success:function(msg){

                        var data = eval("(" + msg + ")"); //这句话解决了json返回数据为undefine的情况

                        var err_code = data[0].err_code;

                        var err_msg = data[0].err_msg;

                        var joinerInfo = data[0].data;

                        if( err_code == 0 )

                        {

                            var str='';

                            var len = joinerInfo.length;

                            for( var i=0; i<len;i++)

                                {

                                    if(i%2 ==0){str += '<tr class="odd">';}

                                    else{str += '<tr class="even">';}

                                    str +=    '<td class="sorting_1">  <input type="checkbox" attr_aid="'+joinerInfo[i].aid+'"/></td> ';

                                    str +=    '<td>'+joinerInfo[i].name+'</td>';

                                    str +=    '<td>'+joinerInfo[i].tel+'</td>';

                                    str +=    '<td>'+getDate(joinerInfo[i].time)+'</td>';

                                    str +=    '<td>'+joinerInfo[i].message+'</td>';

                                    str +=    '<td>'+joinerInfo[i].company+'</td>';

                                    str+=     '</tr>';

                                }

                            $("#joinInfo").html(str);



                        }else{

                            $("#joinInfo").html('');

                                alert(err_msg);

                                return false;

                        }

                },

                error:function(){

                        alert("网络请求失败，请重试！");

                    }

        })

 

提交的表单也可以序列化之后更方便简洁

    $("#addActivityCategory_dialog").dialog({

        autoOpen: false,

        modal: true,

        width:400,

        height:250,

        buttons: {

            确定: function () {

                //序列化表单                    

                var formData = $("#addActivityCategory_form").serialize();

                if($("#activityCategoryName").val() == ""){

                    alert("分类名称不能为空！");

                    return false;

                }

                //console.log(formData);return false;

                //发起ajax请求        

                $.ajax({

                    type:'post',

                    url: 'produce.php?c=activity&a=addActivityCategory',

                    dataType: "json", 

                    data:formData,

                    processData:true,

                    success:function(msg){    

                         var data = eval(msg);

                         var err_code = data[0].err_code;

                         var err_msg = data[0].err_msg;

                         var category = data[0].data;

                        if(err_code == 0){

                            alert(err_msg);

                            $("<option value='"+category.id+"'>"+category.name+"</option>").appendTo("#activityCategory_select")

                            //window.location.reload();

                        }else{

                            alert(err_msg);

                            return false;

                            /*$.each(msg.errors,function(k,v){

                                $('label[for='+k+']').append('<span class="error">'+v+'</span>');

                            });*/

                        }

                    },

                    error:function(){

                        alert("请求失败,请重新发送请求！");

                        return false;

                    }

                });

                

                $(this).dialog("close");

            },

            取消: function () {

                $(this).dialog("close");

            }

        },

        open: function () {

            

        },

        close: function () {

       

        }

    });
