How to access value of the global variable in other function javascript

Question

Here is one of the similar example

var global=0;
function somefunction()
{
    global++;
}

var temp=global;
function somefunctiontwo()
{
    var x=temp;
}

here I am getting x=0 I want x=1

how can I assign newly assigned value of global variable to x

Answer 1

Use an object as global variable; that will be assigned by reference instead of 'by value' as for the simple (number) type:

var global = { value: 0 };

var temp = global;

in function:

global.value++;

now is:

temp.value == 1

Answer 2

temp and global refer to two different variables. Assigning to global will not change the value in temp .

Simply change var x=temp to var x=global . It's not clear why you need an intermediate variable.

Answer 3

var global=0;
var temp;
function somefunction(){
  global++;
}



function somefunctiontwo() {
    var x=temp;
    console.log(x);
}

somefunction();
temp=global;
somefunctiontwo();

This will give what you expect. Pay attention on how/where you call the functions.

Answer 4

Your structure seems a little off, not sure if this is for a reason we can't see... Will presume it is. Can have a function that resyncs the temp value to global.

function syncGlob(){
    return temp = global;
}

Returns temp as well so you can call it when creating x.

var x = syncGlob();

Answer 5

You're setting the value of temp to global PRIOR to the on ready firing - at this point global is 0. If you increment global at on ready, temp already has a value of 0.

When you click somefunction2 and assign x the value of temp, temp has a value of 0, because at the time of temp initiation, global had a value of 0 NOT 1
