检查网址字符串中的重复值

Question

我有url字符串，我想知道它是否包含重复的端口（例如端口），然后多次出现这种情况，例如在这种情况下54001或77777是否存在一次以上？ 我在破折号和下划线js

HTTP：//gr-t6fa45e73.go.grp.corp：54001 / OAuth的/授权RESPONSE_TYPE =代码＆REDIRECT_URI = HTTP％3A％2F％2Fro-d3ma32e85.mo.grp.corp％3A77777％2Flogin％2Fcallback＆CLIENT_ID = zs6.node＆测试= 54001

像这样吗 此纯JS函数尝试搜索与url端口匹配的url参数

 function search() { var url = unescape(document.getElementById("url").innerHTML); var patternPort = /:\\d+/g; var ports = url.match(patternPort); for (i=0; i<ports.length; i++){ var patternParam= new RegExp("=" + ports[i].substr(1), 'g'); if(url.match(patternParam)){ alert(ports[i].substr(1) + " is repeated"); } } } 

 <pre id="url">http://gr-t6fa45e73.go.grp.corp:54001/oauth/authorize?response_type=code&redirect_uri=http%3A%2F%2Fro-d3ma32e85.mo.grp.corp%3A77777%2Flogin%2Fcallback&client_id=zs6.node&test=54001</pre> <button onclick="search()">Search repeated ports on params</button>
