for loop, $i and _setFile

tower120

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.

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

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?

Please, provide email. I cant post it here, it consists several .sah files, and contains passwords for httpAuth.
