![Console. Log Not Working for jQuery? [Duplicate]](https://docuprint.cloud68.co/uploads/console-log-not-working-for-jquery-duplicate_1200.jpg)
Here is my jQuery at the bottom of html page:
<script src="" type="text/javascript">
$(document).ready(function () {
$('#login').click(function() {
var co_id = $('#companies').val();
console.log(co_id);
});
});
</script>
When I type this jQuery into the console, then type co_id it works, but when I run this in browser and choose a company and click the correct button, and I would assume when I type co_id into chrome browser console, it would show my option value? But it is coming back as:
>co_id
ReferenceError: co_id is not defined
Here is html:
<select name="" id="companies">
<option value="--">--</option>
<option value="1">Company</option>
<option value="2">Company2</option>
<option value="3">Company3</option>
<option value="68">Company4</option>
<option value="69">Company5</option>
<option value="70">Company6</option>
</select><input id="login" type="submit" value="Login">

Don't write code if you set the src attribute.
<script src="" type="text/javascript">
</script>
<script type="text/javascript">
$(document).ready(function () {
$('#login').click(function() {
var co_id = $('#companies').val();
console.log(co_id);
});
});
</script>
Your problem is, that the Chrome console is always running in the global scope but co_id is scoped to the closure.
To inspect the values you have 3 options:
Declare co_id to be in the global scope. To do this simply remove the
varin front of the variable name and addvar co_idin the global scope. I don't recommend this, inevitably you'll forget to make the scope local again and you'll end up with a lot of global variables. They can be a source of a lot of fun bugs.Change the
console.log()to actually output the variable content like this:console.log(co_id);.The best solution: Set a break point in the function by clicking on the line number in the script pane.
