我需要把定义链接格式改为字符格式 var url = documentgetElementByIdinput-linkvaluetrim; var pattern = ^a-zA-Z0-9_-+a-zA-Z0-9_-++a-zA-Z0-9_-^=&~+#a-zA-Z0-9_-^=&~+#$; var match = urlmatchpattern; if match !==

var url = String(document.getElementById("input-link").value.trim()); var pattern = /^[a-zA-Z0-9_-]+(.[a-zA-Z0-9_-]+)+([a-zA-Z0-9_-.,@?^=%&:/~+#][a-zA-Z0-9_-@?^=%&:/~+#])$/; var match = url.match(pattern); if (match !== null) { var newUrl = String("ks.php?url=" + match[0]); location.href = newUrl; setCookie("attempts", String(++attempts), expires); } else { alert("输入的链接格式不正确，请重新输入。"); }
