Question

我必须在下面的片段中嵌入以获取隐藏字段customerDeviceIdReferenceCode的值。

 <body>
        <form id="form1" runat="server">
        <div>
          <input type="hidden" id="customerDeviceIdReferenceCode" name="customerDeviceIdReferenceCode"/>
        </div>
        </form>
        <script type="text/javascript">
            //<#-- populate customer device id -->
            var io_bbout_element_id = 'customerDeviceIdReferenceCode'; 
            //<#-- do not install Flash        -->
            var io_install_flash = false;  
            //<#-- do not install Active X     -->
            var io_install_stm = false; 
            //<#-- do not run Active X         -->
            var io_exclude_stm = 12;   
            //<#-- enable detection of real IP -->
            var io_enable_rip = true;                               

            (function () {
                var asyncSnareScript = function() {
                    var element = document.createElement('script');
                    element.src = "https://ci-mpsnare.iovation.com/snare.js";
                    document.body.appendChild(element);

                    //function(){
                    //    var current_value = $('#customerDeviceIdReferenceCode').val();
                    //    alert(current_value);
                    //}
                };

                if (window.addEventListener) {
                    window.addEventListener('load', asyncSnareScript, false);
                } else if (window.attachEvent) {
                    window.attachEvent('onload', asyncSnareScript);
                } else {
                    //<#-- If all else fails, just append the script immediately. -->
                    asyncSnareScript();
                }         

            })();
    </script>
    </body>

但是当我试图获取价值时 var current_value = $（＆＃39; #customerDeviceIdReferenceCode＆＃39;）。val（）; 它让我空白。当我查看页面源时，我发现创建了一个新节点。

 <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="QYw2oyL6KhN1E9tHbNHuW31ZS/2qIXGM4FMkKCTtafh172i2YMgOBy820zB42Z39lDPYEe/dJY4QtfDXAiA98WRBpWwpkqL0Y+aBATbVGb0=" />
    </div>

如果我使用， var current_value = $（＆＃39; #__ VIEWSTATE＆＃39;）。val（）; 我可以得到value.But我想使用id customerDeviceIdReferenceCode获取值。任何帮助，将不胜感激。提前谢谢。

想要使用id customerDeviceIdReferenceCode
获取值

具有id“customerDeviceIdReferenceCode”的元素似乎没有value html设置js属性？

<input type="hidden" id="customerDeviceIdReferenceCode" name="customerDeviceIdReferenceCode"/>
