ajax获取数据

Question

   下面的data-hash="'data[i].datahash'"这样写为什么会报：Unexpected identifier
   要怎么获取

              $.ajax({
                type: "get",
                url: "nav.php",
                cache: false,
                dataType: "json",
                success: function(data) {
                    var data = data;
                    var html = '';
                    for (var i = 0; i < data.length; i++) {
                        html += '<div class="swiper-slide" data-hash="'data[i].datahash'">' + data[i].nav + '</div>';
                    }
                    
                    $(".swiper-wrapper").get(0).innerHTML = html;

                },
                error: function() {
                    alert("出错");
                }
            });

Answer 1

你后面那 都加上+号了

前面的咋就忘了呢

字符串和变量链接 要加上+号

Answer 2

html += '<div class="swiper-slide" data-hash="'data[i].datahash' 这段有问题，“＋”在哪里

Answer 3

html = html + '<div class="swiper-slide" data-hash="' + data[i].datahash + '">' + data[i].nav + '</div>';

Answer 4

html += '<div class="swiper-slide" data-hash="'data[i].datahash'">' + data[i].nav + '</div>';

div里少了+。 data-hash="'+ data[i].datahash +'"
