Ajax请求不使用dataType“jsonp”或“json”

I'm trying to use JSON as a return type for an Ajax request (using jQuery) but my code always results in an error. I've tried changing the MIME type between json and jsonp but to no avail.

I'm also not sure if I'm formatting the data: part correctly. I understand that I need to wrap all of its information in a string for JSON, but I don't know if it's correct.

$.ajax({

    type: "POST",
    url: '-----',
    dataType: "jsonp",
    data: '{"jobtitle":"job"}',

    beforeSend:function(){ },


    success: function(data){
        var data = $.parseJSON(data);           

    },
    error: function(){
        alert("error with Ajax request");
    }

});

Edit: Here is my server-side code. I don't know how to return valid JSON from this.

<?php 


$jobtitle = $_POST["jobtitle"];
$city = $_POST["city"];
$state = $_POST["state"];



$url = "http://www.indeed.com/jobs?q=". $jobtitle ."&l=". $city ."%2C". $state;
$document = new DOMDocument;

$html = file_get_contents($url);
$document ->loadHTML($html);
$xpath= new DOMXPath($document);

$results = $xPath->query('//div[@id="searchCount"]');

$string = "";

if ($results){
    for ($i=0; $i < $results->length; $i++) {
            $node = $results->item($i)->textContent;


    }
    $exp = explode(" ", $node);

    print "Number of jobs: <b>".$exp[5]. "</b>";


}
