On my node.js server I have the following code:
//Generate a token
var token = capability.generateToken();
//Serve the page
var html = fs.readFileSync('learn.htm').toString();
response.writeHead(200, {"Content-Type": "text/html"});
response.end(html);
}
Now on the client side (in learn.htm) I want to access the token variable. My question is, how do I pass the variable to the client in the response? There must be a simple way of doing this but I’m struggling to wrap my head around it.
You could send some JavaScript to the client which sets the variable. Or you could store it in a
data-attribute e.g. of the body tag (<body data-token="...">) and then access it via$('body').data('token')in case you have jQuery on the client side.If you need it for a form you can also store it in a hidden input field.
