Hello,
In this post we are going learn how to do CRUD(Create, Read, Update and Delete) operations using SharePoint2013 REST API .
Before learning how to write the script, you should know where to write the script?
This depends on your requirement, lets suppose if you are implementing a visual web part then you can write the script on your user control( .ascx file) in script tag as shown below. You can write your script in a function and then call that function wherever you want.
In the below script I am calling the script on document ready function
<script type="text\javascript">
$(document).ready( function(){
// Calling function
GetListItembyID();
});
function GetListItembyID(){
//write your script to get the list item based on id here
}
</script>
Or else you can write the script in a Content Editor web part like as mentioned above.
Reading list item based on item id
Here is the following scenario, I just want to fetch some data based on item id from a list.
In this case we need to use GET http method to fetch/read items. Following are the sample snippets which I used to fetch some of the columns(Title, Name, Email ) information of the item having ID as 1 from the list titled EMPMaster.
$.ajax({
url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/GetByTitle('EMPMaster')/getitembyid('1')/?$select=Title, Name, Email",
type: "GET",
headers: {
"accept": "application/json; odata=verbose"
},
success: function(data){
alert(data.d.Title); //You will get title here
alert(data.d.Name); //You will get name here
alert(data.d.Email); //You will get email here
},
error: function(err){
alert("Error while fetching list item: " + JSON.stringify(err));
}
});
Reading multiple list items
In the below snippet I used to fetch columns(Title, Name, Email ) information of all items from the list titled EMPMaster.
$.ajax({
url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/GetByTitle('EMPMaster')/items?$select=Title, Name, Email",
type: "GET",
headers: {
"accept": "application/json; odata=verbose"
},
success: function(data){
// Looping multiple items
$.each(data.d.results, function(index, item){
alert(Item: " + index);
alert(item.Title); //You will get title here
alert(item.Name); //You will get name here
alert(item.Email); //You will get email here
});
},
error: function(err){
alert("Error while fetching list items: " + JSON.stringify(err));
}
});
Inserting list item
In the below snippet I have added list item having columns(Title, Name, Email ) values as "ABC", "XYZ", xyz@abc.com in to the list titled EMPMaster.
$.ajax({
url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/GetByTitle('EMPMaster')/items",
type: "POST",
alert("Item added successfully!");
},
error: function(err){
alert("Error while adding item: " + JSON.stringify(err));
}
});
Updating list item based on item id
In the below snippet I have updated list item column "Name" value to "XYZ1" having id as 1 in the list titled EMPMaster.
$.ajax({
url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/GetByTitle('EMPMaster')/items(1)",
type: "POST",
alert("Item updated successfully!");
},
error: function(err){
alert("Error while updating item: " + JSON.stringify(err));
}
});
Deleting list item based on item id
In the below snippet I have deleted list item having id as 1 in the list titled EMPMaster.
$.ajax({
url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/GetByTitle('EMPMaster')/items(1)",
type: "POST",
alert("Item deleted successfully!");
},
error: function(err){
alert("Error while deleting item: " + JSON.stringify(err));
}
});
So thats it for now. Hope you learn some basic operations using REST apis in SharePoint 2013.
Happy coding. Cheers!!! :)
