you can use this as a mechanism for javascript to dynamical push and pull information from the esp to the browser.


THis javascript function allows for a url to be retrieved and laced in to a variable. Java script can do any thing it wants with that variable.
Also depending on how you format the url you can send information to the esp.

Code: Select allfunction httpGet(theUrl)
{
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", theUrl, false ); // false for synchronous request
    xmlHttp.send( null );
    return xmlHttp.responseText;
}

how to receive data on my board?

- Sat Dec 05, 2015 8:13 pm #35777 The serialprint and input commands allow for sending data out on the serial and pulling information from serial.

These are under base commands in the documentation. Take a look and have the esp hooked up to a serial terminal on the PC so you can experiment with the commands.

The input command requires a cr+lf for the data to be placed in to the variable and is blocking.
