I am trying to find out the right way to approve a listitem workflow task clicking on a button using JavaScript (client object model). An approver should be able to approve/reject his own task by clicking on a link or a button associated with the current item.
-
1var item = list.getItemById(dataTaskId); item.set_item('Completed', true); item.set_item('PercentComplete', 1); item.set_item('Status', "Approved"); item.set_item('WorkflowOutcome', "Approve"); tried updating Nintex outcome column "WorkflowOutcome" with both Approve/ Approved. Task list is updated correctly. But my Nintex workflow did not move forward. It is not able to switch to Approve or Reject branch. Please advicePradeep Kini– Pradeep Kini2019-09-14 16:54:07 +00:00Commented Sep 14, 2019 at 16:54

How to approve workflow task item using JSOM
The following example demonstrates how to approve task item using JSOM
function approveTask(listTitle,itemId, success,error){
var ctx = SP.ClientContext.get_current();
var list = ctx.get_web().get_lists().getByTitle(listTitle);
var item = list.getItemById(itemId);
item.set_item('Completed',true);
item.set_item('PercentComplete',1);
item.set_item('Status','Approved');
item.set_item('WorkflowOutcome','Approved');
item.update();
ctx.executeQueryAsync(
function() {
success();
},
error
);
}
Example
approveTask('Workflow Tasks',1,function(){
console.log('Task has been approved');
},
function(sender,args){
console.log(args.get_message());
});

Workflow task is getting approved, but the Nintex workflow's flexi task is not getting proceeded in the 'Approve' branch.Jefin Mathew– Jefin Mathew2020-11-28 08:55:30 +00:00Commented Nov 28, 2020 at 8:55
var siteURL = "https://xxxxxxxxxxxxxxxxxxxx"; //Your site URL here
var varComments = 'Task approved from test'; //Approver comments
var varOutcome = 'Approve'; //Workflow flexi task outcome
var varTaskListName = 'Workflow Tasks'; //Workflow Tasks list name
var varTaskId = 44; //Workflow task item ID
var webSvc = siteURL + "/_vti_bin/NintexWorkflow/Workflow.asmx";
var rqst = '<?xml version="1.0" encoding="utf-8"?>';
rqst += '<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:m="http://nintex.com">';
rqst += '<soap:Header>';
rqst += '</soap:Header>';
rqst += '<soap:Body>';
rqst += '<m:ProcessFlexiTaskResponse2>';
rqst += '<m:comments>'+varComments+'</m:comments>';
rqst += '<m:outcome>'+varOutcome+'</m:outcome>';
rqst += '<m:spTaskId>'+varTaskId+'</m:spTaskId>';
rqst += '<m:taskListName>'+varTaskListName+'</m:taskListName>';
rqst += '</m:ProcessFlexiTaskResponse2>';
rqst += '</soap:Body>';
rqst += '</soap:Envelope>';
$.ajax({
type: "POST",
url: webSvc,
contentType: "text/xml;charset=UTF-8",
data: rqst,
dataType: "xml",
success: function(data,status,xhr) {console.log('OK: ' + status);},
error: function (data) {console.log(data.responseText);}
});
Using JSOM you can update any list item.
In particular to approve a task item, you should update following fields
taskItem["WorkflowOutcome"] = "Approved";
taskItem["FormData"] = "Completed";
taskItem["Status"] = "Approved";
taskItem["PercentComplete"] = 1;
taskItem["Completed"] = true;
