I am new to node and ejs, I have below code, and need to know how to get the values from EJs file to post it to mongoDB

EJS file

JS file

$('form').on('submit', function(){

      var item = $('form input');
      var user = [{username:item.val()},{password:item.val()},{email:item.val()}];

      console.log(user);

      $.ajax({
        type: 'POST',
        url: '/register',
        data: user,
        success: function(data){
          //do something with the data via front-end framework

      });

      return false;

  });

As of now when I insert to mongo DB I get a new uuid but the values are going in as "0"

Answer 1

So the line var item = $('form input'); is actually a collection of each input, while the line var user = [{username:item.val()},{password:item.val()},{email:item.val()}]; is only grabbing the value of the first one (this is because of how jQuery can appear to hide a collection), instead I would try this (assuming you wanted to grab specific values out of that form):

var items = $('form');
var user = {
      username: $('[name=username]', items).val(),
      password: $('[name=password]', items).val(),
      email: $('[name=email]', items).val()
    };

With following change to your html

<form>
    <p>
        <label for="input-username"> Username </label>
        <input type="text" id="input-username" name="username"/>
    </p>
    <p>
        <label for="input-password"> Password </label>
        <input type="password" id="input-password" name="password" />
    </p>
    <p>
        <label for="input-email"> Email </label>
        <input type="text" id="input-email" name="email"/>
    </p>
    <button type="submit">Log In</button> 
</form> 

Also the for attribute in the <label> element is to associate with an <input> that has an id attribute with the same value. So considering that id s should be unique and only resolve to a single element I would suggest adding some kind of name spacing like input- to them.
