I have a table of rows with contact details and a call button in every row, which when clicked should call the customer.
I am using onclick on call the function defined in external js file (I know not the best practice and potentially due to outside scope, but I am passing the phone number as well)
I am getting error Uncaught Referenceerror: function is not defined
https://jsfiddle.net/e1z25y3w/3/
<table> <th> <td>#</td> <td>Name</td> <td>City</td> <td>Phone Number</td> <td>Call</td> </th> <tr> <td>1</td> <td>John</td> <td>Melbourne</td> <td>+61123456789</td> <td><a role="button" onclick="callPhone('+61123456789')">Call</a></td> </tr> <tr> <td>2</td> <td>Tanya</td> <td>Sydney</td> <td>+61987654321</td> <td><a role="button" onclick="callPhone('+61987654321')">Call</a></td> </tr> </table>
Jquery 3.4.1 included at the bottom of the page javascript file also included after jquery
$(function () { //const phoneNumberInput = document.getElementById("phone-number"); function callPhone(phonenumber) { alert(here); log("calling phone number " + phonenumber.value); //e.preventDefault(); phoneNumberInput = phonenumber; makeOutgoingCall(); } });
What is the best way to execute this?

Answer
because the “callPhone” function isn’t in the global scope, so when you to try call it, will give “callPhone is not defined”.
1- first solution is to write it on the global scope.
function callPhone(phonenumber) { console.log('running') }

2- The second solution is to store it in a global variable.
let referanceStore = null $(function () { //const phoneNumberInput = document.getElementById("phone-number"); function callPhone(phonenumber) { // any code here... console.log('running') } referanceStore = callPhone });
and use referancecStore to call your function ex:
referanceStore('+61987654321')

3- Third solution is to use the javascript click event and dataset instead.
