Update SharePoint list item using REST API

Solution:

Here I create 2 variables as follow:

1)      url : REST API with list name

2)      data : this variable contain the column name with respective values

var url = "/_api/Web/Lists/GetByTitle('CRUDList')/getItemById('1')";

var data = {

__metadata: { 'type': 'SP.Data.CRUDListListItem' },

            Title: 'Update title'

};

Function:

function updateItem(url, updateData) {

$.ajax({

url: _spPageContextInfo.webAbsoluteUrl + url,

type: "PATCH",

headers: {

                        "accept": "application/json;odata=verbose",

                        "X-RequestDigest": $("#__REQUESTDIGEST").val(),

                        "content-Type": "application/json;odata=verbose",

                        "X-Http-Method": "PATCH",

                        "If-Match": "*"

                    },

                    data: JSON.stringify(updateData),

                    success: function (data) {

                        console.log(data);

                    },

                    error: function (error) {

                        alert(JSON.stringify(error));

                    }

                });

            }

Function call:

updateItem(url,data);
