What is the best way to render PartialView to a La

问题:

There is a layout page in my MVC5 project and I want to render all the page contents (partial views) by clicking menu links (hyperlink) on the left side as shown below. There are some methods using Ajax, etc. but I am not sure which approach meets my needs best. Is there any example regarding to this problem containing the Layout page and Controller methods?

You have to first wrap your body content in div and assign any id to it:

<div id="divContentArea">
@RenderBody()
</div>

Now in Script Menu click event:

$(".menuLinkItem").click(function (e) {
    e.preventDefault();        
    var controllerName = $(this).attr('data-controllername');
    var actionName = $(this).attr('data-actionname'); 

    if (String(actionName).trim() == '') {
        return false;
    }
    if (typeof (controllerName) == "undefined") {
        return false;
    }

    var url = "/" + controllerName + "/" + actionName;

    //Open url in new tab with ctrl key press
    if (e.ctrlKey) {
        window.open(url, '_blank');
        event.stopPropagation();
        return false;
    }            

    $.ajax({
        url: url,
        type: 'POST',
        success: function (data) {
            var requestedUrl = String(this.url).replace(/[&?]X-Requested-With=XMLHttpRequest/i, "");
            if (typeof (requestedUrl) == "undefined" || requestedUrl == 'undefined') {
                requestedUrl = window.location.href;
            }

            // if the url is the same, replace the state
            if (typeof (history.pushState) != "undefined") {
                if (window.location.href == requestedUrl) {
                    history.replaceState({ html: '' }, document.title, requestedUrl);
                }
                else {
                    history.pushState({ html: '' }, document.title, requestedUrl);
                }
            }

            $("#divContentArea").html(data);                

        },
        error: function (xhr) {
        }
    });

});

Controller:

[AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post)]
public PartialViewResult Index()
{
        if (HttpContext.Request.HttpMethod == "GET")
        {
            return View();
        }
        else
        {
            return PartialView();
        }
}
