使用JavaScript代码判断输入的字符串是否含有特殊字符和emoji表情代码实例

js判断代码

reg = /[~#^$@%&!?%*]/gi;
if (reg . test(postdata . Name . trim())) {
    alert("姓名不能含有特殊字符");
} else {
    if (isEmojiCharacter(postdata . Name . trim())) {
        alert("姓名不能含有表情");
    } else {
//自己的代码
    }
}
function isEmojiCharacter(substring) {
    for (var i = 0; i < substring . length; i++) {
        var
        hs = substring . charCodeAt(i);
        if (0xd800 <= hs && hs <= 0xdbff) {
            if (substring . length > 1) {

                ls = substring . charCodeAt(i + 1);
                var
                uc = ((hs - 0xd800) * 0x400) + (ls - 0xdc00) + 0x10000;
