Using getSelected() method of StandardSetController class

Question

I am new to salesforce. My purpose is to display all the values of the selected checkboxes on one page, to the pther VF page. I studied that this can be done by getSelected() method. But I am unable to use it. Please can someone explain me with an example of VF page.

Is there any other method to achieve this goal?

Answer 1

In custom button you can write something like this:

    // Assuming you have standardcontroller for Case object
    var records = {!GETRECORDIDS($ObjectType.Case)};

    var updateRecords = [];

    if (records[0] == null) {
        alert("Please select at least one Case to update.");
    } else {
        window.location = 'apex/MyVisualforcePage?recs='+records.join(',');
    }

After that you can get all selected record from the parameter named recslike that and do whatever you want:

List<String> caseIds = ApexPages.currentPage().getParameters().get('recs').split(',');
