}</pre>
i纠正它作为val（''）回答1再到val（）我得到同样的错误关闭
JavaScript运行时错误：无法获取未定义或空引用的属性'客户'
JavaScript运行时错误：SignalR：加载集线器时出错。确保集线器引用正确，例如< script src ='/ signalr / js'>< / script> ;.
{throw new Error（SignalR：加载集线器时出错。确保集线器引用正确，例如< script src ='/ signalr / js'>< / script> ;.）;
建议我解决方案或示例
i corrected it answer 1 as val('') to val() again i getting same errors as follows
"JavaScript runtime error: Unable to get property 'client' of undefined or null reference"
"JavaScript runtime error: SignalR: Error loading hubs. Ensure your hubs reference is correct, e.g. <script src='/signalr/js'></script>."
"{throw new Error("SignalR: Error loading hubs. Ensure your hubs reference is correct, e.g. <script src='/signalr/js'></script>.");"
suggest me the solution or example
