上传html到SPIFFS,html - Importing JQuery via SPIFFS ESP8266 - Stack Overflow

I have a working code that works well. The essence of the code is that the person connects to the Wi-Fi network, transfers him to the Captive Portal in which he enters some text that is sent to esp8266. But this does not work that way, since I want to do all this without connecting to the network, then importing JQuery from the server is not suitable, you need to do this by connecting JQuery through a file. So for this I loaded it into the esp8266 file system, but I could not find information on how to include this file in the html code now. Please tell me how to do this?

dnsServer.start(DNS_PORT, "*", apIP);

webServer.onNotFound([]() {

webServer.send(200, "text/html", handleRoot);

});

webServer.on ("/send", handleSend);

webServer.begin();

}

void loop() {

dnsServer.processNextRequest();

webServer.handleClient();}
