检测是否IP或者域名源码

源码是通过创建ScriptControl对象,通过JS来实现的。

function check(ip) {
var ipArray, j;
if (ip.indexOf(" ") >= 0) {
    ip = ip.replace(/ /g, "");
}
if (ip.toLowerCase().indexOf("http://") == 0) {
    ip = ip.slice(7);
}
if (ip.toLowerCase().indexOf("https://") == 0) {
    ip = ip.slice(8);
}
if (ip.slice(ip.length - 1) == "/") {
    ip = ip.slice(0, ip.length - 1);
}
if (/[A-Za-z_-]/.test(ip)) {
