<script>
//in one script
var someVarName_10 = 20;
</script>
I want to get access to this variable from another script by name of variable. With window object its simple, is it possible with local variable?
I mean access this var by code like this:
<script>
alert(all_vars['someVar' + 'Name' + num]);
</script>
Do you want to do something like this?
<script>
//in one script
var someVarName_10 = 20;
alert(window["someVarName_10"]); //alert 20
</script>
Update: because OP edited the question.
<script>
num=10;
alert(window['someVar' + 'Name_' + num]); //alert 20
</script>
This is not my own answer, its Arthur Araújo's answer, but I think its relevent here.
Eval alternative:
exp = '1 + 1'
x = Function('return ' + exp)()
console.log(x)
If this is what you said:
<script type="text/javascript">
var hello = 'test';
</script>
<script type="text/javascript">
alert (hello);
</script>
It works because script are finally available to the document and you can access their vars.
