Character Limit using JQuery in SharePoint

2 comments  
In this post, we will learn how to implement Character Count (here in this example, maximum allowed 2000 characters) using JQuery in SharePoint.

Prerequisite:
1. Create a SharePoint List with a column named "Comments" - data type Multi line text with plain text as the option selected
2. SharePoint Designer 2013 for editing the SharePoint list with span and to identify the ID of the field created

Solution:
1. Open the SP site in SharePoint designer, navigate to the list -> Create a custom new form -> Edit it.
To know how to create a custom new form in SharePoint Designer, read this article.
2. Below is the HTML code for my "Comments field in SharePoint Designer: 

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
<tr>
    <td width="190px" valign="top" class="ms-formlabel">
        <H3 class="ms-standardheader">
   <nobr>Enter your comment:</nobr>
  </H3>
    </td>
    <td valign="top" class="ms-formbody" style="background-color:#ffffff; width:400px;">
        <SharePoint:FormField runat="server" id="ff6{$Pos}" ControlMode="New" FieldName="Comments" __designer:bind="{ddwrt:DataBind('i',concat('ff6',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Comments')}" />
        <SharePoint:FieldDescription runat="server" id="ff6description{$Pos}" FieldName="Comments" ControlMode="New" />
        <span title="2000" id="commentsCount">2000</span><span> Characters Left</span>
    </td>
</tr>
Make a note that I have added a Span tag below the SharePoint control to display the Characters. Also, we have declared it as 2000 characters for this example.
Now, add a script tag or a separate file (then refer it inline) -> add the below code in it save it:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

$(document).ready(function() {
 //Character count for comments text
 $("textarea[name*='ff6']").keyup(function () {
  characterCount('ff6', '#commentsCount');
 });
});

//Character count for multiline text 
function characterCount(controlID,spanId)
{
  var controlVal = $("textarea[name*='" + controlID + "']");
  var cmax = $(spanId).attr("title");
  if(controlVal.val().length >= cmax) {
      controlVal.val(controlVal.val().substr(0, cmax));
   }
  $(spanId).text(cmax - controlVal.val().length);            
}
In this above JS, "ff6" is the ID of the SharePoint control.
Save the form and JS, try typing inside the control you can see the characters been automatically counted and decreases as you type. Cool Isn't it? 😉

Accessing Radio Buttons using JQuery in SharePoint Online

19 comments  
I couldn't find anything obvious for accessing SharePoint Radio Buttons so chucked this together, hopefully useful for someone else :)
Note: The below code/solution is applicable to accessing radio button in a custom SharePoint List forms. To know how to create a custom form in SharePoint Online, read this article 
Accessing Radio Button control in SharePoint is little tricky than accessing the radio buttons in HTML. The reason being, radio buttons are rendered as a table instead of a single control as shown below (radio button and it's preview in developer tools - Chrome):

 So, each radio button is rendered inside SPAN tag in a table. To access the normal SharePoint controls, we will use either ID or title property but for Radio Buttons it is little complicated.
1. The actual radio button control is in "input" tag 
2. The values (Example here: Yes, No) are inside "label" tag 
3. But each control (Yes & No) are represented by ID which is generated by SharePoint 
4. If you keenly look at the ID, there is "ff41" which is the ID of the control generated randomly by SharePoint.

 Now, open the designer, add an ID to the TD of the Radio button so that we can query it easily using JSOM as shown below:

1
2
3
4
//Radio button change event
$("td[id='tdApproved'] input:radio[name*='ff4']").change(function(){
     // do something
});


1
2
3
//Clear the values of radio button - reset the values of radio button
$("td[id='tdApproved'] input[name*='ff4']")[0].checked = false;
$("td[id='tdApproved'] input[name*='ff4']")[1].checked = false;


1
2
3
4
//Checking the value of radio button
if($("td[id='tdApproved'] input:radio[name*='ff4']:checked +  label").text() != 'Yes'){
    // do something
} 


1
2
//Focus Radio button 1st element in control
$("td[id='tdApproved'] input:radio[name*='ff4']:eq(0)").focus();


1
2
3
4
5

//Align all Radio Buttons in the page horizontally
function HorizontalAlignChoices() {
    var objSpans = $(".ms-RadioText");
    objSpans.each(function () {
        if ($(this).is("span")) {
            $(this).closest("tr").css({ "float": "left" });
        }
    });
}

*** "tdApproved" is the ID of the SharePoint Radio Button Control, "ff4" is the unique ID of the SharePoint Control in your List form. Change this ID according to your form to get the exact result.

Get Current Logged in User & Manager using REST API in SharePoint Online

4 comments  
Scenario: 
Environment: SharePoint Online 
Approach:      Populating Current logged in user in People Picker. Also populating user's Manager automatically using REST API and SP Services.
Solution:
1. Create an SharePoint custom list "Learning" (in my case).
2. Create two columns with the following names and data types shown below:
         Internal Name                      Title                                                   Type
CurrentLoggedinUser           Current Logged in User Person or Group (People Only)
Manager                              Manager Person or Group (People Only
3. When you try adding a new item in the list, it should look like:
Here the two people pickers are SP 2013 people picker type where it will show the matching users while typing few words automatically.
4. Now open the list in SharePoint Designer, Create a New Custom Form and make it as default as shown below in the screenshots:

Open the new custom form in Advanced Mode, where you can edit the List Form. Try viewing the page by clicking F5 or Preview in Browser icon in top left corner in the designer.
5. You can see the difference in People Picker. When you create a custom list form, the default forms are automatically changed to SharePoint old type. (for more details read this blog).
6. Now add the ID for both fields as shown below. Also, add the reference the JQuery in the form 
7. Now add the ID's for the two people picker values so that it will be useful for querying the SharePoint controls as shown below. 
 8. Add a JS file ("Learning.js") in the Site Assets Library and refer it in the new form. Add the below code in the newly created "Learning.js" file.

$(document).ready(function() {
 var userAccountName= $().SPServices.SPGetCurrentUser();
 //Set current logged in user and manager name in people picker
 LoadPeoplePickerDetails();
 //Show the form fields on document.ready()
 $("#onetIDListForm").show();
});
 
/****************** All function defintions starts here********************************/
//Function to set people picker values
function LoadPeoplePickerDetails()
{
 var url=_spPageContextInfo.webAbsoluteUrl + "/_api/SP.UserProfiles.PeopleManager/GetMyProperties"
 getReqData(url,function(data){    
 try 
 {
         //Get properties from user profile Json response  
         var userDisplayName = data.d.DisplayName;
         var AccountName = data.d.AccountName;
         $("#tdCurrentUser [id$='upLevelDiv']").html(AccountName);
         $("#tdCurrentUser [id$='checkNames']").click();
         var Manager = data.d.ExtendedManagers.results;
         $("#tdManager [id$='upLevelDiv']").html(Manager[Manager.length-1]);
         $("#tdManager [id$='checkNames']").click();             
 }
 catch(err){
   
  }               
     },
     function(data){
       //alert("some error occured in getting current User info");
     });
}

function getReqData(reqUrl,success, failure) {
 $.ajax({
  url: reqUrl, 
  method: "GET",
  headers: { "Accept": "application/json; odata=verbose" },
  success: function (data) {
   success(data);
  },
  error: function (data) {
   failure(data);
  }
 });
}
9. Save the JS and the custom new form as well.
10. Now, try adding a new item. The current logged in user and the current logged in user's manager name will be automatically set in the people picker as shown below.

11. It is basically, on document.ready(), REST API call is made and it populates the data on the form load.

Note: 
1. The people picker for Manager field is loaded after getting the value from current logged in user field. Hence if you have to change the user, the manager value is set during document.ready(). If you want to change the user and set the manager field, then write a method for setting value of manger and call it on value set in first people picker
2. I have implemented only in  Custom New Form only.

For ease of use, I have shared the js and the List Template. Please use this link to download.

In the above tutorial, you have learned how to create a Custom Form in SharePoint Online, make REST API calls and also set the values to the People Picker in the list form.
