javascript - Include a global variable value in onclick property - Stack Overflow

I am using javascript onclick attribute. How to use a global varibale in that? Global variable in JS file:

var globalVar;
globalVar = "Some String";

Now i want to use the above string my jsp page:

<a href="#" onclick="myFunction(globalVar)">Link</a>

But its just passing as string i.e., the parameter is just passing as globalVar as a string but not its value. Can any one tell me how to apply this global variable value inside the attribute?

• if you just need to access globalVar, you can even access its value in myFunction. You don't need to pas it as argument. It is already available to every function – Muhammad Usman Commented Nov 1, 2017 at 4:05

you can use alternate way like this in html

<a href="#" onclick="myFunction()">Link</a>

in javascript

<script>
        var globalVar='somestring';
        function myFunction(){
        console.log(globelVar);
        }
        </script>

Global arguments can be referenced inside an onclick function. Example:

var test_value = 3;

function test(val){
  console.log(val);
}

<a onclick="test(test_value)">TEST </a>

Wrap them in a function like myFunction1(), and change it to:

    <a href="#" onclick="myFunction1">Link</a>
    ....
    ....

    function myFunction1() {
          myFunction(globalVar);
    }

You can try like this, a global variable is something which is declared in a page, outsite of a javascript function ,and is fully accessible any where in that page. So for that, declare the variable outside of the function and call it from anywhere.like

<script>var globalVar = "global Variable";
 function(){
 ////
}
</script>

call variable as,

<script>function myFunction(){
   console.log(globalVar );
  }</script>

Hope this will help.Thanks.
