Introduction
This article explains how to create an item in a list in SharePoint 2013 using CSOM-JavaScript.
Prerequisites
The following are the prerequisites:
- Ensure you have access to the Office 365 online.
- Ensure Napa tool is available in your site.
Procedure
The following is the procedure to be followed:
- Create an App For SharePoint Using Office 365 Tools. If you have missed out on how to create an app in SharePoint 2013, then Click here.
- Create a list and name it “MyCustomList”. Click here if you want to learn how to create a list.
- Create a field in the list. Click here if you want to learn how to create a field in a list.
- Click on the "Default.aspx" page.
 
 ![aspx page]() 
 
 
- Add Title and MyCustomField text boxes and a button to create an item and place it inside the “PlaceHolderMain” tag.
 Title : <input type="text" name="txtTitle" id="txtTitle"></input><br/><br/><br/> MyCustomField : <input type="text" name="txtCustom" id="txtCustom"></input><br/><br/><br/> <button id="btnCreateItem" onclick="createItem()">Create a New item</button><br/>
 
 ![create an item]() 
 
 
- Click on the "App.js" file.
 
 ![js file]() 
 
 
- Globally declare the content, web and list objects as shown below.
 
 var context = SP.ClientContext.get_current(); //gets the current contextvar web = context.get_web(); //gets the web object var list = web.get_lists(); //gets the collection of lists
 
 
- Now write the function to create an item in a list as in the following:
     function createItem() {         // Retrieve the list and add an item to it.         var targetList = list.getByTitle("MyCustomList");         //create a new item object         var listItemCreation = new SP.ListItemCreationInformation();         //add the item to the list using addItem method         var newItem = targetList.addItem(listItemCreation);         var listItemTitle = document.getElementById("txtTitle").value;         alert(listItemTitle);         var listItemCustom = document.getElementById("txtCustom").value;         alert(listItemCustom);         //using set_item method u can set the values to the item fields         newItem.set_item('Title', listItemTitle);         newItem.set_item('MyCustomField', listItemCustom);         newItem.update();         context.load(newItem);         context.executeQueryAsync(ItemCreationSuccess, ItemCreationFail);     }
 
 
- Here in this example we are creating an item in a list using the “ListItemCreationInformation” object.
- After creating the listitem object we need to add the object to the list using the additems method.
- Then set the values of the item field using the set_item method. 
- Then we need to load the new item object and execute the code by calling "executeQueryAsync".
 function ItemCreationSuccess() {         $('#message').text = "";         $('#message').text("Item got created");     }     function ItemCreationFail(sender, args) {         alert('Failed to create a new item. Error:' + args.get_message());     }
 
 
- That’s it! Now let's start testing.
Testing 
- Now to run the app click on the "Play" button available towards the left-most corner.
 
 ![Play button]() 
 
 
- The app is packaged, deployed, and installed on your Office 365 Site.
 
 ![app]() 
 
 
- Now you will be able to see the page where you can enter the details and store it in the list.
 
 ![page with enter detail]() 
 
 
- Enter the details and click on the “create a new item” button.
 
 ![Enter the details]() 
 
 
- To see the item that was recently created, just go to the following URL:
 
 Syntax: https://yoursite/Lists/ListName
 Example: https://mysite/Lists/MyCustomList
 
 ![item created]()
