            cb(data[0].thumbnail_large);

    }
}

在javascript中(使用jQuery):

function vimeoLoadingThumb(id){    
    var url = "http://vimeo.com/api/v2/video/" + id + ".json?callback=showThumb";

    var id_img = "#vimeo-" + id;

    var script = document.createElement( 'script' );
    script.src = url;

    $(id_img).before(script);
}


function showThumb(data){
    var id_img = "#vimeo-" + data[0].id;
    $(id_img).attr('src',data[0].thumbnail_medium);
}

要显示它:

<img id="vimeo-{{ video.id_video }}" src="" alt="{{ video.title }}" />
<script type="text/javascript">
  vimeoLoadingThumb({{ video.id_video }});
</script>

最简单的JavaScript方式，我发现，获得缩略图，无需搜索视频id是使用:

//Get the video thumbnail via Ajax
$.ajax({
    type:'GET',
    url: 'https://vimeo.com/api/oembed.json?url=' + encodeURIComponent(url),
    dataType: 'json',
    success: function(data) {
        console.log(data.thumbnail_url);
    }
});

注意:如果有人需要获得与视频id相关的视频缩略图，他可以将$id替换为视频id，并获得一个包含视频详细信息的XML:

http://vimeo.com/api/v2/video/$id.xml

例子:

http://vimeo.com/api/v2/video/198340486.xml

源

如果你想通过纯js/jquery没有api使用缩略图，你可以使用这个工具从视频中捕获一帧，瞧!插入url拇指在任何你喜欢的来源。

这是一支码笔:

<img src="https://i.vimeocdn.com/video/531141496_640.jpg"` alt="" />

分解Karthikeyan P的答案，使其可以用于更广泛的场景:

// Requires jQuery

function parseVimeoIdFromUrl(vimeoUrl) {
  var match = /vimeo.*\/(\d+)/i.exec(vimeoUrl);
  if (match)
    return match[1];

  return null;
};

function getVimeoThumbUrl(vimeoId) {
  var deferred = $.Deferred();
  $.ajax(
    '//www.vimeo.com/api/v2/video/' + vimeoId + '.json',
    {
        dataType: 'jsonp',
        cache: true
    }
  )
  .done(function (data) {
    // .thumbnail_small 100x75
    // .thumbnail_medium 200x150
    // 640 wide
        var img = data[0].thumbnail_large;
        deferred.resolve(img);  
    })
  .fail(function(a, b, c) {
    deferred.reject(a, b, c);
  });
  return deferred;
};

使用

从Vimeo视频URL获取Vimeo Id:

var vimeoId = parseVimeoIdFromUrl(vimeoUrl);

从vimeo Id获取一个vimeo缩略图URL:

getVimeoThumbUrl(vimeoIds[0])
.done(function(img) {
    $('div').append('<img src="' + img + '"/>');
});
