Why can't I use this variable in my for loop?


Why can't I use this variable in my for loop?

will be helpful for those in need First of all, you need to run 'for' loop inside the click handler. Currently you bind a click handler inside a 'for' loop, so try this:
code :
$('button').on('click', function(i) {
    $('#funbox').text('');
    var formappend = parseInt($('input[name=inputform]').val());
    if(isNaN(formappend)) return false;

    for (var i = 0; i < formappend; i++){      
        var newblock = $("<div class='block'></div>").text("");
        $('#funbox').append(newblock);
    }
});

Why does local variable inside foreach loop conflict with variable declared outside the loop?

it should still fix some issue While you can only refer to the outer foo after you declared it, locals are allocated at the beginning of a function which means the inner foo will overshadow the outer one, even if it hasn't been declared yet.

Does that help This functionality can now easily be achived in Ember (since 1.13) using the new and awesome inline helpers mut and get:
The way to achieve this is in two basic steps:
code :
{{#each rows as |r|}}
<tr>
  {{#each headers as |h|}}
  <td>
    <input onkeyup={{action (mut (get r h)) value="target.value" }}>
  </td>
  {{/each}}
</tr>
{{/each}}

this will help In Java, if I want to create nested loops where the inner loop variable depends on the outer loop variable (e.g. in typical bubble sort implementations), I can do something like this:
code :
for i in range(0, n):
    for j in range(i, n):
        #do something

I hope this helps . I think this is what you are attempting to do. I really don't understand why you are doing what you are doing which is half the battle when trying to help someone code something.
code :
@ECHO off
SETLOCAL EnableDelayedExpansion
FOR /L %%j IN (1,1,5) DO (
    FOR /F %%i IN ('FINDSTR /C:"%%j:" tests.txt') DO (
        SET PH=%%i
        SET mon=!PH:~2,1!
        ECHO mon=!mon!
        FOR /F "delims=" %%G IN ("!mon!") do SET test%%j=!PH:~6,%%G!
        ECHO test%%j=!test%%j!
    )
)
