我在这里尝试了大约 10 个其他问题的答案,但似乎没有任何效果。我已经尝试过每个地图和grep。
我想更改对象文字中的值,然后更新我的列表。
这是数组:
goals = [
{
goalguid: "691473a7-acad-458e-bb27-96bac224205b",
category: "personal",
datecreated: "2013-10-20",
startdate: "2013-10-28",
enddate: "2013-11-26",
goal: "go to store",
icon: "cart",
status: "completed",
username: "jtmagee",
userguid: "0c7270bd-38e8-4db2-ae92-244de019c543"
}, {
goalguid: "9e693231-e6d8-4ca9-b5c8-81ea7a80a36a",
category: "personal",
datecreated: "2013-10-20",
startdate: "2013-10-27",
enddate: "2013-11-27",
goal: "Brush Teeth",
icon: "doctor",
status: "inprogress",
username: "jtmagee",
userguid: "0c7270bd-38e8-4db2-ae92-244de019c543"
}, {
goalguid: "8d23005d-f6f3-4589-bb85-a90510bccc21",
category: "work",
datecreated: "2013-10-20",
startdate: "2013-10-26",
enddate: "2013-11-28",
goal: "Arrive on Time",
icon: "alarm",
status: "inprogress",
username: "jtmagee",
userguid: "0c7270bd-38e8-4db2-ae92-244de019c543"
}, {
goalguid: "ac879673-19eb-43f6-8b95-078d84552da0",
category: "school",
datecreated: "2013-10-20",
startdate: "2013-10-24",
enddate: "2013-11-29",
goal: "Do Math Homework",
icon: "book",
status: "missed",
username: "jtmagee",
userguid: "0c7270bd-38e8-4db2-ae92-244de019c543"
}
];
我正在关闭从用户单击的 li 获得的目标引导。我使用状态键更改 li 上的类。
这是我的 jQuery,它捕获了对复选框的点击:
$(".goals").delegate("input[type=checkbox]", "click", function() {
goalguid = $(this).parent().parent().data("goalguid");
emailGoal = $(this).parent().data('goal');
if ($(this).prop("checked")) {
$(this).parent().parent().removeClass("inprogress missed").addClass("completed").prop("checked", true);
updateStatus = 'completed';
return updateTheGoal();
} else {
$(this).parent().parent().removeClass("completed").addClass("inprogress").prop("checked", false);
updateStatus = 'inprogress';
return updateTheGoal();
}
});
这是我无法工作的地方。一些尝试完全清除了数组,但大多数尝试,包括这个,除了让我的列表闪烁之外什么都不做。displayGoalList 函数适用于其他用途。
updateTheGoal = function() {
var goalList;
$.each(goals, function() {
if (goals.goalguid === goalguid) {
return goals.status === updateStatus;
}
});
goals = JSON.parse(localStorage["goals"]);
goalList = $.grep(goals, function(e) {
return e.userguid === userguid;
});
localStorage.setItem(userguid + "Goals", JSON.stringify(goalList));
logSummary();
return displayMyGoalList();
};
任何帮助深表感谢。谢谢。
