python , angular js 学习记录【1】

1.日期格式化

Letter Date or Time Component Presentation Examples
G Era designator Text AD
y Year Year 199696
M Month in year Month JulyJul07
w Week in year Number 27
W Week in month Number 2
D Day in year Number 189
d Day in month Number 10
F Day of week in month Number 2
E Day in week Text TuesdayTue
a Am/pm marker Text PM
H Hour in day (0-23) Number 0
k Hour in day (1-24) Number 24
K Hour in am/pm (0-11) Number 0
h Hour in am/pm (1-12) Number 12
m Minute in hour Number 30
s Second in minute Number 55
S Millisecond Number 978
z Time zone General time zone Pacific Standard TimePSTGMT-08:00
Z Time zone RFC 822 time zone -0800

2.scope之间通信(angular js)

父scope定义一个方法(假设controller为ParentCtrl)

$scope.$on('change-breadcrumb', function(event,data) {
$scope.breadcrumb = Util.breadcrumb("h"+$routeParams.id,data);
});

子scope触发父scope的方法(假设controller为ChildCtrl)

 $scope.$emit('change-breadcrumb',newValue);

此时可以执行父scope里面的方法,要注意的是在页面中的两个controller的位置

<div ng-controller="ParentCtrl">                <!--父级-->
<div ng-controller="ChildCtrl"></div> <!--子级-->
</div>

页面弹出框dialog不属于上面的页面布局,使用方法为

dialog.context_scope.$emit('change-breadcrumb',newValue);

更多细节请参见AngularJS的学习--$on、$emit和$broadcast的使用 - 疯狂的原始人

3.$.grep angular.forEach

$.grep() 方法是按照某种条件来过滤数组

nums = $.grep(nums, function (num, index) {
// num = 数组元素的当前值
// index = 当前值的下标
return isNaN(num);
});

angular.forEach方法用来循环数组

 angular.forEach($scope.templates, function (t) {
if ($scope.pool.template.id == t.id) {
$scope.pool.template = t;
     }
})

两者都有循环数组的功能,在angular js 中尽量用后者进行循环

4.使用session

angular.module('cvirt.login', ['ngCookies'])
.controller('loginController', loginController)
.controller('logoutController', logoutController);

在controller中声明session,并设置值即可

$cookieStore.put('token', escape(data.token));
$cookieStore.put('username', $scope.username);

获取session中的值

$cookieStore.get('username')
