javascript - 契约(Contract)名称抛出未定义的错误？

Question

  Mortgage.new({ from: ownerAccount, gas: defaultGas }).then(
    function(loanInstance) {
        loanContractAddress = loanInstance.address;
        $('#sectionAAddress').html('<i class="fa fa-address-card"></i> ' +

抵押是合约名称

var Mortgage = artifacts.require("./Mortgage.sol");

module.exports = function(deployer) {
  deployer.deploy(Mortgage);
};

抵押.sol

pragma solidity ^0.4.4;

contract Mortgage {

  function Mortgage()
  {
    loanApplicant = msg.sender;
    loan.status = STATUS_INITIATED;
    balances[msg.sender] = 100000000;
  }

  /* address of the loan applicant */
  address loanApplicant;

我得到以下 js 错误界面

Uncaught ReferenceError: Mortgage is not defined at deployLoanContract (app.js:22316) at HTMLButtonElement. (app.js:22610) at HTMLButtonElement.dispatch (jquery.min.js:3) at HTMLButtonElement.r.handle (jquery.min.js:3) deployLoanContract @ app.js:22316 (anonymous) @ app.js:22610 dispatch @ jquery.min.js:3 r.handle @ jquery.min.js:3
