js ajax的简单使用

function apply() {
    goods_no = $('#goods_no').val();
    num = $('#num').val();
    flow_no = $('#flow_no').val();
    if (flow_no == '') {
        alert('单号不能为空');
        return false;
    }
    $.ajax({
        cache: false,
        url: '/user/welcome/send_to_weiphone.html',
        dataType: 'json',
        type: 'post',
        data: {
            goods_no: goods_no,
            num: num,
            flow_no: flow_no
        },
        success: function (msg) {
            if (msg.code == 1) {
                alert('申请成功');
            } else if (msg.code == -1) {
                alert('申请失败，原因：已经发生了交易，不可修改，建议将物品手动下架后重新发

布');
            } else if (msg.code == -2) {
                alert('申请失败，原因：所填数量大于发布数量');
            }
        }
    });
}


function send_del(i) {
    var ok = confirm('确认要删除该发货地址？');
    if (ok == true) {

        var id = document.getElementById("table" + i).getElementsByTagName("TR")

[0].getElementsByTagName("INPUT")[0].value;

        $.ajax({
            url: '/user/welcome/send_delete_address.html',
            data: { id: id },
            type: 'post',
            cache: false,
            success: function (ret) {
                if (ret == 1) window.location.reload();
                else alert('删除失败！');
            }

        });
    }
}
