Javascript语法错误？

Question

Hey what am I doing wrong? My JS file stopped working, I've tried different ways but it doesn't work. I want to start the function with a button click with "id".

$(document).ready(function () {
    $("#paybutton").click(function () {}
    var params = ("projectpaymentoption=1197&id=");
    var usernamepay = window.localStorage.getItem("username");
    var paymenturl = params + usernamepay;
    }

    $.ajax({
        type: 'post',
        url: 'http://www.bla.de/phone/encode.php',
        data: {
            data: {
                "usernamepay": usernamepay
            },
        }
        success: function (result) {
            console.log(result);
        }
    });

Formatted Code below. Please use some IDE from next time.

$(document).ready(function... function has been closed with }); at the bottom. $("#paybutton").click(function(){.. has been closed appropriately with });

Removed extra data: { declaration, put a , before success: function(). Corrected other indentations as well.

$(document).ready( function() {
    $("#paybutton").click(function() {
        var params = ("projectpaymentoption=1197&id=");
        var usernamepay = window.localStorage.getItem("username");
        var paymenturl = params + usernamepay;
        $.ajax({
             type: 'post',
             url: 'http://www.bla.de/phone/encode.php',
             data: {"usernamepay": usernamepay},
             success: function(result) {
             console.log(result);
              }
        });                         
    });
});
