for loop, $i and _setFile

Hi!

When I use $i variable in for loop it increases each time
function uploadFile($elementID, $fileName){
    _setFile(_file($elementID), $settings.getUploadDir()+$fileName, "upload/file_from_swf?action=upload");
}


for (var $i=1; $i<=13; $i++) {
    _alert($i);

    $fname = "op_hd\\"+$i+".png";

    $oname = "picture_file_"+$i;

    _alert($i);
    uploadFile( $oname, $fname );
    _alert($i);
    _alert("ende");
}


After _setFile command $i increases. Without it all seems OK.
Also, if $i replace with $ij - it also ok.

    Hi tower120,

    Could you please be more specific about the issue.

    Well, normally it should alert in this order:
    1
    2
    3
    4
    5
    6
    etc.

    with _setFile inside loop it act like this:
    1
    3
    5
    7
    9
    etc.

    Put some file input in the form and try to do _setFile() inside for $i loop.

    Hi tower120,

    I had verified running below Sahi script on below mentioned html page :
    function uploadFile($elementID, $fileName){
    _setFile(_file($elementID), $fileName);
}

for (var $i=1; $i<=13; $i++) {
    _alert($i);
    $fname = "c:/qhdebug.log";
    //$fname should have a valid filepath in your system
    $oname = "fileupload0";
    uploadFile( $oname, $fname );
}

    Note: There are chances that $i might be used as global variable and some where else $i is getting incremented.

    <html>
    <form name="f1" action="test1.html">
    <input type="file" id="fileupload0" name="fileupload1">
    </form>
    </html>

    Here is the output that i am getting,

    1
    2
    3
    4
    5
    6
    etc.

    But 
    for (var $i=1; ...
    does not that mean that I use local variable $i inside loop?

    By the way, why I cant use variables without $ ?

    Hi tower120,

    When you write
    _alert(i);
    Sahi will search for the variable i on the browser (and will not get it)
    When you write
    _alert($i);
    Sahi will evaluate $i on the proxy and pass it to _alert on the browser.

    Also, Can you post the full Sahi script?
