推荐答案

由于Vimeo视频的网址由 http://vimeo.com/ 后跟数字ID组成，可以执行以下操作

As URLs for Vimeo videos are made up by http://vimeo.com/ followed by the numeric id, you could do the following

var url = "http://www.vimeo.com/7058755";
var regExp = /http:\/\/(www\.)?vimeo.com\/(\d+)($|\/)/;

var match = url.match(regExp);

if (match){
    alert("id: " + match[2]);
}
else{
    alert("not a vimeo url");
}
