Question

我在这个本地存储阵列上遇到了困难。希望你能帮帮我。

这是我的代码..

var bank = document.getElementById('name_bank').value;

function AddBank(bank){ 
  var data = JSON.parse(localStorage.bank); 
    if(!$.inArray( bank, data )){
    data[]=bank;
  }
   localStorage.setItem("bank", JSON.stringify(data)); 
}

我的错误Uncaught SyntaxError: Unexpected token ]

</button>
<script>

console.log(bank);
  var data = [];
  aa = JSON.parse(localStorage.getItem("bank"))
  if(aa != null){
    data= aa;
  }
  if(bank != null){
  data.push(bank)
  }
