How To CheckIn And CheckOut a SharePoint page using JavaScript(JSOM)

Hi Friends,

Recently I have come across a requirement where I need to update the properties of a Sharepoint page. In this post we are going to see how to checkin and checkout a page in sharepoint using JSOM.
Below are the code snippets.

CheckOut:
function checkOut(){
        var ctx = SP.ClientContext.get_current();
        var page = ctx.get_web().getFileByServerRelativeUrl(window.location.pathname);
        //you can use any path. Here I am using current page.
        page.checkOut();
        ctx.load(page);
        ctx.executeQueryAsync(Function.createDelegate(this, checkOut_Success),
                                            Function.createDelegate(this, checkOut_Fail));
}
function checkOut_Success(sender, args){
 alert("Checked Out");
//do your actions
}
function checkOut_Fail(sender, args){
   alert("Fail checkout");
}

CheckIn:
function checkIn(){
         var ctx = SP.ClientContext.get_current();
        var web = ctx.get_web();
        var page = web.getFileByServerRelativeUrl(window.location.pathname);   
        //you can use any path. Here I am using current page.  
        page.checkIn();
        page.publish();
        ctx.executeQueryAsync(Function.createDelegate(this, checkIn_Success),
                                            Function.createDelegate(this, checkIn_Fail));
}
function checkIn_Success(sender, args){       
    alert(" checked in "); 
}
function checkIn_Fail(sender, args){   
    alert("Fail  checked in "+args.message);
}

Hope this helps...
