[英]How to use push technology with embedded product using php, javascript, html?
问题描述
I am looking to implement push technology with embedded product. 
我希望通过嵌入式产品实现推送技术。 can anyone please help me? 谁能帮帮我吗？ Actually I am working on a GUI using php, smart, prototype.js, html, css from where a user of wi-fi product can change the settings on board. 实际上，我正在使用php，smart，prototype.js，html，css在GUI上进行工作，而wi-fi产品的用户可以在其中更改板载设置。 and the size of that product is very less only 8MB where we have around 6MB's files already. 而且该产品的大小非常少，只有8MB，而我们已经拥有大约6MB的文件。 Actually every time we are sending the AJAX request to wi-fi board to get the latest information about GPSvalues but sometimes nothing has been changed in board but AJAX requesting to board. 实际上，每次我们向wi-fi董事会发送AJAX请求以获取有关GPS值的最新信息时，有时AJAX要求登机的情况都没有改变。 So my question is that is there any way that board will let browser know whenever new data is there?? 所以我的问题是，只要有新数据存在，董事会有什么办法让浏览器知道？ Please reply if you have the answer.... 如果您有答案，请回复。
