Expected token-error when inserting a variable into a string - Javascript


var value = liste[eigenschaft];
document.getElementById("demo6").innerHTML = value;
var data = '{"products":[{"ingramPartNumber":"7U0169"}, {"ingramPartNumber":"6XH440"}]}';

I made a successful request for an API from one of our online-distributors. In the var data (as shown above) I can list the name/value-pairs (e.g.: ingramPartNumber and the actual partNumber) and I get back the corresponding data.

However, we want to make the call a bit more dynamic. We implemented a search and we want to have the value of the search (in the example above the var value) as an actual value in var data.

However, if I substitute the product-number with the variable (as shown below), it throws an error (expected token identifier) .. What am I missing?

var value = liste[eigenschaft];
document.getElementById("demo6").innerHTML = value;
var data = '{"products":[{"ingramPartNumber":"7U0169"}, {"ingramPartNumber":"'value'"}]}';

Solution

  • You are doing this

       var data = '{"products":[{"ingramPartNumber":"7U0169"}, {"ingramPartNumber":"'value'"}]}';
    

    Where you should be using interpolation or concatenation

       var data = '{"products":[{"ingramPartNumber":"7U0169"}, {"ingramPartNumber":' + value + '}]}';
