前台通过window.localStorage存储用户名

var storage = window.localStorage;
            if ($("#rember").is(":checked")) {
                storage["name"] = $("#name").val();
                storage["password"] = $("#password").val();
                storage["isstorage"] = "yes";
                alert(1);
            }
            else {
                storage["name"] = "";
                storage["password"] = $("#password").val();
                storage["isstorage"] = "";
                alert(2);
            }

　　开始加载的时候判断是否已存储用户名：

var storage = window.localStorage;
        if ("yes" == storage["isstorage"]) {
            $("#rember").attr("checked", true);
            $("#name").val(storage["name"]);
        }
        else {
            $("#rember").attr("checked", false);
            $("#name").val(storage["name"]);
        }

　　

<input type="checkbox" class="ace" id="rember" name="rember" />
