Hello all, this is my first post to this list. I am fairly new to
WWW::Mechanize, but I have been in pretty good shape so far. I have run
into a page that has a javascript link to another page and I can't get by
it. I am trying to use push_input to get by that way, but I can't seem to
translate the javascript to see what I should configure. Below is the
javascript snippet. Any help is appreciated.

Thanks.

<script language="JavaScript" type="text/javascript">
function setAndSubmit(actionName, formObj, varNameAndValueArray)
{
for(var i = 0; i < varNameAndValueArray.length; ++i)
{
eval("document."+formObj.name+"."+varNameAndValueArray[i]+". value=\""+varNameAndValueArray[++i]+"\";");
}

//if NN4
if(document.layers)
{
var whichDummy;
//if there is more than one form variable named dummy
//find the first one that hasn't been renamed and use it
if( formObj.dummy.length != null )
{
var done = false;
for(i=0; i < formObj.dummy.length && !done; ++i)
{
if( formObj.dummy[i].name == "dummy" )
{
whichDummy = i;
done = true;
}
}
if( !done )
{
alert("Error: All dummy variables used up!");
}

eval("document."+formObj.name+".dummy[whichDummy].name=\""+a ctionName+".x\"");
}
//if there is only one dummy field, just use it
else
{

eval("document."+formObj.name+".dummy.name=\""+actionName+". x\"");
}
formObj.submit();
}
}
</script>


Above is the function that gets passed the variables, here is the
snippet that calls the function.


<input type=hidden name=GroupId value="">
<td valign=top>
<!-- ugly script to write out image link for netscape or image button for IE-->
<script language="JavaScript" type="text/javascript">
//if NN4
if(document.layers)
{
document.write("<input type=\"hidden\" name=\"dummy\" value=\"1\" />");
document.write("<a
href=\"javascript:setAndSubmit('EDIT_STORE_RULES_GROUP',
document.updateAccount, ['GroupId', '524789']);\"><img
src=\"/nhin/jsp/images/editstorehours.gif\"
alt=\"EDIT_STORE_RULES_GROUP\" border=\"0\" /></a>");
}
else
{
document.write("<input type=image
src=\"/nhin/jsp/images/editstorehours.gif\"
name=\"EDIT_STORE_RULES_GROUP\"
onclick=\"javascript:setAndSubmit('EDIT_STORE_RULES_GROUP',
document.updateAccount, ['GroupId', '524789']);\"
alt=\"EDIT_STORE_RULES_GROUP\" />");
}
</script>

Have you tried sniffing your browser's HTTP requests to see what happens
when that JS executes? Firefox has a nice plugin called Tamper Data
that does this.
