例如，您想要在按钮客户端上获取cookie值连按一下:

For example you want to get the cookie value on button client click even:

<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="GetCookie('StudentCookies')" />

在head 标记内使用以下脚本:

Use following script within head tag:

<script type="text/javascript">
    function GetCookieValue(check_name) {
        var a_all_cookies = document.cookie.split(';');
        var a_temp_cookie = '';
        var cookie_name = '';
        var cookie_value = '';
        var b_cookie_found = false; // set boolean t/f default f

        for (i = 0; i < a_all_cookies.length; i++) {
            // now we'll split apart each name=value pair
            a_temp_cookie = a_all_cookies[i].split('=');
            // and trim left/right whitespace while we're at it
            cookie_name = a_temp_cookie[0].replace(/^\s+|\s+

/g，'); // 如果提取的名称与通过的check_name相匹配 如果(cookie_name == check_name){ b_cookie_found = true ; // 我们需要处理cookie没有值但存在(无=符号)的情况: 如果(a_temp_cookie.length> 1 ){ cookie_value = 不转义(a_temp_cookie [ 1 ].replace(/^ \ s + | \ s +

/g, ''); // if the extracted name matches passed check_name if (cookie_name == check_name) { b_cookie_found = true; // we need to handle case where cookie has no value but exists (no = sign, that is): if (a_temp_cookie.length > 1) { cookie_value = unescape(a_temp_cookie[1].replace(/^\s+|\s+
