Passing JavaScript variable inside the function

Question

I'm facing a problem that with my Laravel project in JavaScript part.

My issue is that I have a form and when taking the variable outside the function it becomes empty ("") and works only inside the function

<form method="POST" action="#">
  @csrf

SHOW

and when taking a variable only works inside the function and outside always empty here's my script part:

<script type="text/javascript">
    var package1 = $('input[name="package"]:checked').val();
    var name1 = $('input[name="name"]').val(); //name
    var phone1 = $('input[name="phone"]').val(); //phone
    var email1 = $('input[name="email"]').val(); //email
    var password1 = $('input[name="password"]').val(); //password
    $("#show").click(function() {
        console.warn(name1);//result ""


        // if i write var package1 = $('input[name="package"]:checked').val(); and others inside the function here it works. 
     });
 </script>

This seems like the very basics of scoping - the variables outside are page-load time set, while inside the click handler it's click-time — josh.trow

Try in this way

$(document).ready(function(){
// Get value on button click and show alert
$("#myBtn").click(function(){
    var str = $("#myInput").val();
    alert(str);
});

});
