Passing data in javascript

Question

Next, how can I pass data between two files with javascript? Example:

Archiv11:

<script>
var dado = 'dado';
</script>

Arquivo2:

<script>
alert (dado);
</script>

Answer 1

You have to consider two things:

• both are in the same scope (overall or common)
• the variable is closed before the alert();. Meaning that code loaded first.

If they are not in the same scope you can use a global object for that variable to be accessible:

Archiv11:

<script>
window.dado = 'dado';
</script>

Arquivo2:

<script>
alert(window.dado);
</script>

If you are using different HTML pages you can use API of localstorage and use localstoragein view of the example with window that I hit on.
