In this post, I will explain how to restrict multiple users on a people picker field in a SharePoint Form (NewForm or EditForm).

Firstly, we need to get the people picker field id



Use the below code and set the AllowMultipleUsers to false

var pp;

 SP.SOD.executeFunc('clientpeoplepicker.js', 'SPClientPeoplePicker', function () {

pp = SPClientPeoplePicker.SPClientPeoplePickerDict["UserName_xxxxxxx_$ClientPeoplePicker"];

 pp.AllowMultipleUsers = false;

        });

Another way is to get the count of users in the people picker field and restrict the save on PreSaveAction()

TotalUserCount will give the number of users in the peoplepicker field.

function PreSaveAction() {

var count = pp.TotalUserCount;

    if (count > 1) {
        alert("Multiple users in people picker field");
  return false;
    }
  return true;
}

In SharePoint 2013, Microsoft introduced the new Workflow manager for managing the SharePoint 2013 workflow which needs to be installed separately. At the same time, the workflow service (2010 workflow) was retained as same. So by doing this, we have the option to create both SharePoint 2013 and SharePoint 2010 workflows using SharePoint Designer 2013.

Many new features were introduced in 2013 workflows such as stages and REST calls within workflow which definitely makes workflow a powerful tool for a developer.

Another interesting feature is the ability to trigger a 2010 workflow from the 2013 workflow. This will give the developer capability to club both the workflows together in order to achieve complex functionalities.

But there is one drawback, we don't have an out of box option in SharePoint 2013 workflow to start another 2013 workflow. Only a SharePoint 2010 workflow can be started.
But we do have an interesting alternative approach to achieve this using REST API call from a S…

JavaScript replace function can be used to replace a part of string inside a string variable.Take an example string - "one, two, three, four" Using JavaScript replace function
var str= "one, two, three, four"; str= str.replace(',',''); - but this will replace only the first occurrence of "," which will give the result as 
"one two, three, four"
if you want to remove all occurrences of the string, following RegExp can be used.
var str="one, two, three, four";str.replace(/,/g ,""); This will give output as "one two three four"
