Problem while sending data through jquery

Question

I am sending data through jquery. my equivalent code is...

$('#pcpmnum').blur(function(){
//alert("HIiiiiii");
var pcpmnum = $("#pcpmnum").val();
if(pcpmnum === "" | pcpmnum === null)
    { 
        alert("Please Enter Mobile Number");
    }
else
    {
        alert(pcpmnum);
        $.post("searchpcp.php", {cntctnumber: "+pcpmnum+"}, function(){
            alert("Success");
                    }
    }

});

on my php file I have simply used.

echo "HIIII";

Is this $.post function is equivalent to Ajax function?

$.post is a shortcut for $.ajax so you don't have to fill in as many options. — Richard Dalton

$.post is a shorthand for $.ajax with certain presets (api.jquery.com/jQuery.post). From the code it should be calling the searchpcp.php properly, but why do you pass the pcpmnum as a string instead of passing its value (without the quotes and the +es)? — m90

simply do

  {cntctnumber: pcpmnum, second:"second variable" }

and in the php file you can get the value as

$contact = $_POST["cntctnumber"]; // you will get the value of pcpmnum here
$sec = $_POST["second"]; // you will get "second variable" here

in the success call back the argument data in your case contains the server response e.g. in you php file you are echoing

...
echo"howdy";

on the client side data will be holding this response

 $.post("searchpcp.php", {cntctnumber: pcpmnum, second:"second variable" }, function(data){
            alert(data);//howdy
           });
