Java pressing "Check All" button

How would I get Screen Scraper to simply press the "Check All" button? (Screen Scraper Free Version)

Here's the live site I'm trying to do this on. I want to "Check All" then hit "View Names". http://tinyurl.com/ss-example1 That's only one days worth of data and the names that populate on that site vary daily. Example day 2: http://tinyurl.com/ss-example2

When I use the screen scraper proxy, the POST data changes depending on which names populate in that list. Basically, the "Select All" option isn't a value in the post data as it is in the "Hello World" tutorial you have posted.

Any ideas? Maybe I should invoke a Script to select all and view names? what might that code look like?

The button is JavaScript, and

The button is JavaScript, and screen-scraper won't run it. You just need to emulate the POST request, and can use addPOSTHTTPParameter for it. I might scrape the from values, save the whole dataSet as a session variable, and before he next scrapeable file run a script like:

// Script to dynamically create POST parameters for next page

// Function to actually create the parameter
makeParam(name, value, index)
{
   scrapeableFile.addHTTPParameter(new com.screenscraper.common.HTTPParameter(name,value,index,com.screenscraper.common.HTTPParameter.TYPE_POST));
}

// Dataset that contains each parameter as a dataRecord
params = session.getVariable("Next page parameters");
// Clear so large values don't linger in memory
session.setVariable("Next page parameters", null);

session.log("+++There are " + params.getNumDataRecords() + " parameters");

// Loop through each paramter
for (i=0; i<params.getNumDataRecords(); i++)
{
        param = params.getDataRecord(i);
       
        key = param.get("NAME");
        // The the key is "eventtarget", I need to set the value from a seperate location
        if (key.equals("__EVENTTARGET"))
                value = session.getVariable("PAGE");
        else
                value = param.get("VALUE")!=null ? param.get("VALUE") : "";
       
        session.log("Making param: " + key + "=" + value);
        makeParam(key, value, i+1);
}

Thanks.

Thanks.
