How to check if current page is the default page of the current site using jsom or REST?

Question

In SP2013, how can I check if the current page is the default page of the current site using javascript object model or REST api?

Thanks

Answer 1

At first get the current page from _spPageContextInfo

var currentPage = _spPageContextInfo.serverRequestPath

Now make a GET request in following end-point to get default or welcome page

_api/Web/RootFolder/WelcomePage

After getting the response, check if both are same.

PS: It works in team & publishing site both.

Sample code is jQuery & REST API

SP.SOD.executeFunc("SP.js", "SP.ClientContext", function() {
    var currentPage = _spPageContextInfo.serverRequestPath
    $.ajax({
        url: _spPageContextInfo.webAbsoluteUrl + "/_api/Web/RootFolder/WelcomePage",
        type: "GET",
        headers: {
            "accept": "application/json;odata=verbose",
        },
        success: function(data) {
            if (currentPage.indexOf(data.d.WelcomePage) > -1) {
                console.log("Current page is default");
            } else {
                console.log("Current page is not default");
            }
        },
        error: function(error) {
            alert(JSON.stringify(error));
        }
    });
});

SP.SOD.executeFunc is important, you are executing code on publishing site
