查看您的页面，我看不到 jsFiddle 附带的 JavaScript。
我看到一个名为“imagemapster”的插件，但它似乎与您的小提琴示例中的代码无关。
进一步调查确认您没有在小提琴中包含来自 JS 窗口的相关 JavaScript。
您需要添加此脚本：
// javascript
// Set up some options objects: 'single_opts' for when a single area is selected, which will show just a border
// 'all_opts' for when all are highlighted, to use a different effect - shaded white with a white border
// 'initial_opts' for general options that apply to the whole mapster. 'initial_opts' also includes callbacks
// onMouseover and onMouseout, which are fired when an area is entered or left. We will use these to show or
// remove the captions, and also set a flag to let the other code know if we're currently in an area.
var inArea, map = $('#beatles'),
captions = {
paul: ["Paul McCartney - Bass Guitar and Vocals",
"Paul McCartney's song, Yesterday, recently voted the most popular song "
+ "of the century by a BBC poll, was initially composed without lyrics. "
+ "Paul used the working title 'scrambled eggs' before coming up with the final words."],
ringo: ["Ringo Starr - Drums",
"Dear Prudence was written by John and Paul about Mia Farrow's sister, Prudence, "
+ "when she wouldn't come out and play with Mia and the Beatles at a religious retreat "
+ "in India."],
john: ["John Lennon - Guitar and Vocals",
"In 1962, The Beatles won the Mersyside Newspaper's biggest band in Liverpool "
+ "contest principally because they called in posing as different people and voted "
+ "for themselves numerous times."],
george: ["George Harrison - Lead Guitar and Vocals",
"The Beatles' last public concert was held in San Francisco's Candlestick "
+ "Park on August 29, 1966."]

// Bind to the image 'mouseover' and 'mouseout' events to activate or deactivate ALL the areas, like the
// original demo. Check whether an area has been activated with "inArea" - IE<9 fires "onmouseover"
// again for the image when entering an area, so all areas would stay highlighted when entering
// a specific area in those browsers otherwise. It makes no difference for other browsers.
map.mapster('unbind').mapster(opts).bind('mouseover', function() {
if (!inArea) {
map.mapster('set_options', all_opts).mapster('set', true, 'all').mapster('set_options', single_opts);
}
}).bind('mouseout', function() {
if (!inArea) {
map.mapster('set', false, 'all');
}
});
