In JQuery, you need to set the return data type (dataType) to json so the function knows what type of data to expect and process. From the manual:

"json": Evaluates the response as JSON and returns a JavaScript object. In jQuery 1.4 the JSON data is parsed in a strict manner; any malformed JSON is rejected and a parse error is thrown. (See json.org for more information on proper JSON formatting.)

You can do this with the full $.ajax() call, or you can use $.getJSON(). There is no HTTP POST shortcut to return JSON (i.e. $.postJSON doesn't exist), but you can supply the dataType parameter to $.ajax() or just add the parameter to $.post() . When you have a JSON object, use json.keyName to access the data.

$.ajax({
    url: "currentPage.php",
    data: { 
        'currentPage': 1
    },
    dataType: "json",
    type: "post",
    success: function(data) {
        $("body").append(data);  
    }
});
