            Custom Button Example: Mass Delete

            Available in: Salesforce Classic

            Custom buttons and links are available in: All Editions

            Visualforce pages and s-controls are available in: Contact Manager, Group, Professional, Enterprise, Performance, Unlimited, and Developer Editions

            Note
            Note

            JavaScript custom buttons are supported in all editions, in Salesforce Classic only. The mass delete function described here doesn’t work in editions where the API isn’t enabled.

            1. Define a button for cases with these attributes.
              Display Type List Button

              Select Display Checkboxes (for Multi-Record Selection) so users can select multiple records in the list before clicking the button.
              Behavior Execute JavaScript
              Content Source OnClick JavaScript
              Use this sample code:
              {!REQUIRESCRIPT("/soap/ajax/9.0/connection.js")} 

var records = {!GETRECORDIDS( $ObjectType.Event )}; 
var taskRecords = {!GETRECORDIDS( $ObjectType.Task)}; 
records = records.concat(taskRecords); 


if (records[0] == null) { 
alert("Please select at least one record.") } 
else { 

var errors = []; 
var result = sforce.connection.deleteIds(records); 
if (result && result.length){ 
var numFailed = 0; 
var numSucceeded = 0; 
for (var i = 0; i < result.length; i++){ 
var res = result[i]; 
if (res && res.success == 'true'){ 
numSucceeded++; 
} else { 
var es = res.getArray("errors"); 
if (es.length > 0) { 
errors.push(es[0].message); 
} 
numFailed++; 
} 
} 
if (numFailed > 0){ 
alert("Failed: " + numFailed + "\nSucceeded: " + numSucceeded + " \n Due to: " + errors.join("\n")); 
} else { 
alert("Number of records deleted: " + numSucceeded); 
} 
} 
window.location.reload(); 
}
            2. Add the button to your activity list views.
            3. Add the button to any page layout that contains an activity-related list. The button deletes any selected task or event in the list.

            You can install custom buttons from the Mass Delete app at https://appexchange.salesforce.com/.
