页面未使用本地存储更新

Question

我正在使用本地存储更新页面，但是页面会刷新，并且不会随着函数调用的更改而更新。但是，当我使用控制台手动添加此代码时，页面会更新。我认为在访问本地存储之前无法完全接收本地存储可能是个问题，但我不确定。

JavaScript：      

<script>
function searchHouse() {
        console.log("hit");

        var element = "";
        var list = document.getElementById('listOfHouses');

        var houses = JSON.parse(localStorage.getItem('HouseList'));
        var houseArray = houses.filter(function (house) {
            //var dropdown = document.getElementById('dropdown');
            var price = document.getElementById('selectPrice').value;
            var squareft = document.getElementById('selectSquareft').value;
            var bedroomsNumber = document.getElementById('selectBedrooms').value;
            var bathroomsNumber = document.getElementById('selectBathrooms').value;

            return house.Price < price && house.Squareft > squareft && house.BedroomsNumber == bedroomsNumber && house.BathroomsNumber == bathroomsNumber;

        });
        console.log(houseArray);
        for (var i = 0; i < Object.keys(houseArray).length; i++) {

            element += "<li>";
            element += "<label>Price : " + houseArray[i].Price + "</label>";
            element += "<br />";
            element += "<label>Square ft : " + houseArray[i].Squareft + "</label>";
            element += "<br />";
            element += "<label>Number of Bedrooms : " + houseArray[i].BedroomsNumber + "</label>";
            element += "<br />";
            element += "<label>Number of Bedrooms : " + houseArray[i].BathroomsNumber + "</label>";
            element += "<br />";
        }
        list.innerHTML = element;

 </script>
