Post data from client to Node server
I can post data to node server though i can't access the data in my app.get route.
orders.hbs (ajax):
$.post( "/show_items", { o_id: result } );
app.js:
app.post ('/show_items', function(req,res){
var order_num = req.body.o_id;
});
app.get('/orders',authenticationMiddleware(), function(request, response){
console.log(order_num);
...
}
The problem is that in my app.get i can't access the $order_num variable. How can i access the variable and use it?

I want to know the use-case before answering. As you sent the data in POST-API, it should ideally be available/used by all middlewares (functions) defined to POST-API.
@Yoni: You are trying to use info passed in POST API (under property req.body.order_num) in altogether different GET API.
But if you want to access it anyway then solution shared by @Bostrot works fine.
while invoking GET API, pass the row_id as
htttp://domain_name.com/v1/path/endpoint?row_id=12 In server code (In API), fetch and use row_id as var row_id = req.query.row_id– ravi_kumar_yadav

htttp://domain_name.com/v1/path/endpoint?row_id=12
var row_id = req.query.row_id
As order_num gets defined in app.post it is a local variable and only available under that scope. If you want to access it in app.get you need to define it before and then just set it:
order_num
app.post
app.get
var order_num;
app.post ('/show_items', function(req,res){
order_num = req.body.o_id;
});
...
app.get('/orders',authenticationMiddleware(), function(request, response){
console.log(order_num);
}
Hi thanks, though for some reason order_num doesn't save its change after app.post. So i am still stuck.

It most likely does. I guess what you are encountering is that
app.get is called before order_num has a value. You should consider putting the app.get request somewhere where you are sure that it already has a value like in app.post direclty.– Bostrot

app.get
order_num
app.get
app.post
I assume you are correct. My problem is that I want that data to constantly change. When the user clicks the row on the table, ajax sends a post to app.js and the variable order_num changes. How can that be done?

Hi, I have an html page with a table. I would like that when the user clicks on a row, it sends the id of the row to app.get route in my app.js node server.
