Node.js - 在app.js中获取href的ID

Question

I am using an href to link the user to a route. My problem is that I need to send a parameter to the dashboard while clicking on the link. The easiest way to do this would be to get the id or name of the href in the app.js and send it to the dashboard.

Here is my code:

 //the href in the index.ejs
 <a href="/dashboard" id="ANDROID">ANDROID</a> 

 //in the app.js
 app.get('/dashboard', function(req, res) {
     var url = req.url;
     console.log("url: " + url);    //prints out url: /dashboard
     var id = req.url.id;
     console.log("id: " + id);      //prints out id: undefined
 });

How can I grap the id or name of the href?

Answer 1

If I understand correctly, you need to pass the parameter to the URL. The ID of the "a" element is only a DOM ID and it is not in any way connected to the URL the link leads to.

You could try something like this:

<a href="/dashboard?id=ANDROID" id="ANDROID">ANDROID</a>

Then in the code:

app.get('/dashboard', function(req, res) {
    var id = req.query.id;
    ...
});
