Question

为什么，当我在var title = $("myInput").value()输入时，API标记无法获得价值？如果我直接插入值 - var title = "some text"，它就可以了！

＆＃13;

(function() {
    var flickerAPI = "https://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=?&api-key=d1c0be70688307ed71f305474f32c559&secret=04bb4c80a0753d23";
    $("#submit").click(function() {
        var title = $("myInput").value();
        $.getJSON(flickerAPI, {
          tags: title,
          tagmode: "all",
          format: "json"
        }).done(function(data) {
          $.each(data.items, function(i, item) {
            $("<img>").attr("src", item.media.m).appendTo("#images");
            if (i === 3) {
              return false;
            }
          });
        });
      }
    });
  });
};

简单的拼写错误...你缺少哈希，它将目标识别为ID：

var title = $("#myInput").value();

为什么闪烁的API标签不能获得输入值？
