Question

Is there any way to send a variable to another function? like for this example:

function test2(){
    $('body').append(lol);
}

function test1(){
    var lol = "test";
    test2();
}

Answer 1

You can either prepare an argument for test2():

function test2(elem)
{
    $('body').append(elem);
}

function test1()
{
    var lol = "test";
    test2(lol);
}

Or declare lol outside of the functions so it’s available to both..

var lol;

function test2()
{
    $('body').append(lol);
}

function test1()
{
    lol = "test";
    test2();
}
