我是Bootstrap在IE11中选择用户.

当我用ajax填充数据并打开它然后它自动向下移动病房,当我选择任何值时,它没有被选中.如何删除此错误？

jQuery.ajax({
        url: base_url + "UserBusinesses/ajaxState/" + countryId,
        dataType: 'json',
        beforeSend: function () {
            $('#UserBusinessStateId').html('<option value="">Loding... </option>');
            $('#UserBusinessStateId').selectpicker('refresh');
            $('#UserBusinessCityId').html('<option value="">Select city</option>');
            $('#UserBusinessCityId').selectpicker('refresh');
        },
        success: function (obj) {
            var addHtml = '';
            addHtml += '<option value="">Select state</option>';
            $.each(obj, function (key, value) {
                var selected = "";
                if (selectedState == key) {
                    var selected = "selected='selected'";
                }
                addHtml += "<option value='" + key + "' " + selected + ">" + value + "</option>";
            });
            jQuery("#UserBusinessStateId").html(addHtml);

            $('#UserBusinessStateId').selectpicker('refresh');

        }
    });

我正在使用paypal rest api,我不知道如何创建client_id和clientSecret.如果您有任何想法,请告诉我...

谢谢

$array1 = array("a"=>1, "b"=>2, "c"=>3, "d"=>4, "e"=>5);
print_r(array_filter($array1, "odd"));


function odd($var)
{
    // returns whether the input integer is odd//

    return($var & 1);
}

在返回值中有什么操作&符？它如何返回奇数

我在MongoDB中嵌入文档我怎么能在那里的pin码只删除一个地址:140901和更新其中的pin码为:152364

db.add_fun.insert({
"_id" : ObjectId("5a82e6dc1139b572569fa785"),
"name" : "Vikas",
"salary" : 72.0,
"address" : [ 
    {
        "address_id" : ObjectId("5a82f0e51139b572569fa78c"),
        "address" : "Mullanpur ",
        "pincode" : "140901",
        "country" : "India"
    }, 
    {
        "address_id" : ObjectId("5a82f0e51139b572569fa78d"),
        "address" : "mohali ",
        "pincode" : "152364",
        "country" : "India"
    }
]
})

我试试这个但不行

db.add_fun.update({},
        {
            $pull: {
                        address: {
                            $elemMatch: {
                                pincode: "140901"
                            }
                        }
            }
        },
        {
            multi:true
        }
    )

想要删除这个

{
"address_id" : ObjectId("5a82f0e51139b572569fa78c"),
"address" : "Mullanpur ",
"pincode" : "140901",
"country" : "India" …

我有 2 个查询，我想知道哪个查询最好

Model::select('id')->where('status','1')->first();


Model::lists('id')->where('status','1')->first();

请告诉我
