Delete the SharePoint ListItem using ECMA Script

Note:-
Use Delete() function in Delete Button onclick event, for DropDown Binding View my Previous article posted before this.

function Delete()

{

                ExecuteOrDelayUntilScriptLoaded(DeleteRecord, "sp.js");

}

function DeleteRecord()

{

                if(document.getElementById("ddlItemID").selectedIndex==0)

                {

                                alert('Please Select UserName');

                                return false;

                }

                var context = new SP.ClientContext.get_current();

    var web = context.get_web();

    var list = web.get_lists().getByTitle('Login');

    var LoginRecord = list.getItemById(document.getElementById("ddlItemID").options(document.getElementById("ddlItemID").selectedIndex).value);

    LoginRecord.deleteObject();

    context.executeQueryAsync(Function.createDelegate(this, this.DeleteSuccess), Function.createDelegate(this, this.DeleteFailed));

}

function DeleteSuccess()

{

                alert('Record Deleted Successfully');

                document.getElementById("tdItemID").innerHTML="";

                Bind();

                document.getElementById("ddlItemID").selectedIndex=0;

               

}

function DeleteFailed(sender, args)

{

                alert('Delete Failed');

}

Binding SharePoint ListItems to DropDownList using ECMA Script

Note:-
Use Bind() function in the Page Load. Before that Create a TD with ID tdItemID.

function Bind()

{

    ExecuteOrDelayUntilScriptLoaded(BindDropDown, "sp.js");

}

function BindDropDown()

{

                var context = new SP.ClientContext.get_current();

    var web = context.get_web();

    var list = web.get_lists().getByTitle('Login');

    var sQuery="<View><Query><OrderBy><FieldRef Name='ID' /></OrderBy></Query></View>";

     var camlQuery = new SP.CamlQuery();

      camlQuery.set_viewXml(sQuery);

      this.myColl = list.getItems(camlQuery);

      context.load(this.myColl, 'Include(Title, ID)');

      context.executeQueryAsync(Function.createDelegate(this, this.BindSuccess), Function.createDelegate(this, this.Bindfailed));

}

Bind();

function BindSuccess()

{

                var listEnumerator = this.myColl.getEnumerator();

                var strDropDown="";

                strDropDown+="<Select id='ddlItemID'>";

                strDropDown+="<Option>";

                strDropDown+="Select Username";

                strDropDown+="</Option>";

                while (listEnumerator.moveNext())

                {

                    var item = listEnumerator.get_current();

                    strDropDown+="<Option value='"+item.get_item('ID')+"'>";

                    strDropDown+=item.get_item('Title');

                    strDropDown+="</Option>";               

    }

   strDropDown+="</Select>";

                if(document.getElementById("tdItemID"))

                {

                                document.getElementById("tdItemID").innerHTML=strDropDown;

                }

}

function Bindfailed(sender, args)
{
    alert('failed. Message:' + args.get_message());
}

Search and Update using Client Object Model

Note:-
Use Edit() Function in Search Button Onclick event  and Update() Function in Update Button Onclick Event.

var strItemID="";

var myColl="";

 function Edit()

{

    ExecuteOrDelayUntilScriptLoaded(SearchRecord, "sp.js");

}

function Update()

{

    ExecuteOrDelayUntilScriptLoaded(UpdateRecord, "sp.js");

}

function SearchRecord()

{

                try

                {

                var context = new SP.ClientContext.get_current();

    var web = context.get_web();

    var list = web.get_lists().getByTitle('Login');

                var sQuery = '<View Scope=\'RecursiveAll\'>'+

                        '<Query>'+

                            '<Where>'+

                            '<Eq>'+

                                '<FieldRef Name=\'Title\'/>' +

                                '<Value Type=\'Text\'>' + document.getElementById("txtUserName").value +'</Value>'+

                            '</Eq>'+

                            '</Where>'+

                        '</Query>'+

                             '</View>';

        var camlQuery = new SP.CamlQuery();

        camlQuery.set_viewXml(sQuery);

        this.myColl = list.getItems(camlQuery);

        context.load(this.myColl, 'Include(Title, Password, ID)');

        context.executeQueryAsync(Function.createDelegate(this, this.SearchSuccess), Function.createDelegate(this, this.failed));

                }

                catch(ex)

                {

                                alert(ex.message);

                }

}

function SearchSuccess()

{

                document.getElementById("divItemID").innerHTML="";

                var listEnumerator = this.myColl.getEnumerator();

                while (listEnumerator.moveNext())

                {

                    var item = listEnumerator.get_current();               

                    document.getElementById("txtPassWord").value = item.get_item('Password');

                    document.getElementById("divItemID").innerHTML=item.get_item('ID');

                    break;

    }

}

function failed(sender, args) {

    alert('failed. Message:' + args.get_message());

function UpdateRecord()

{

                var context = new SP.ClientContext.get_current();

    var web = context.get_web();

    var list = web.get_lists().getByTitle('Login');

    var LoginRecord = list.getItemById(strItemID);

    LoginRecord.set_item('Password', document.getElementById("txtPassWord").value);

    LoginRecord.update();

    context.executeQueryAsync(Function.createDelegate(this, this.Updatesuccess), Function.createDelegate(this, this.Updatefailed));

}

function Updatesuccess()

{

                alert("Record Updated Successfully");

                document.getElementById("txtUserName").value="";

                document.getElementById("txtPassWord").value="";
