I'm setting up a form on a static page, where users will "input" text + "select" option, then the "submit"button should modify the iframe "scr" url to https://example.com/"text value"+"option "
I went on some other pages, but couldn't find a simple script to it
<form>First name:<br>
<input type="text" name="firstname">
<select>
<option value="A">A</option>
<option value="B">B</option>
</select>
<input type="submit" value="Submit">
</form>
<iframe src="https://example.com/"> </iframe>
<script> ... </script>
