我想使用 window.localStorage.setItem 保存数据，但我发现此错误：

JavaScript ERROR: TypeError: 'null' is not an object (evaluating 'window.localStorage.setItem')

在我的 connexion.js 中

$("#btn-connexion").on('click', function() {    
    var username = $('#Identifiant').val();
    var password = $("#mdp").val();         

    console.log("********username*******password****");
    console.log(username);

    $.ajax({
        "url": serverPath + "/taxiws/clients/login/password/" + username + '/' + password,
        "type": "GET",
        "dataType": "json",
        "success": function(data) {
            console.log("****Resultat****");
            console.log(JSON.stringify(data));                   

            window.localStorage.setItem("login", username);
            window.localStorage.setItem('password', password);
            window.location.href = "reservationclient.html";
        }
    });
});
