angularjs-指令-防止重复提交，第一次点击提交后必须相隔几秒后才能点击

myApp.directive('noMoreSubmit', ['$interval', function ($interval) {
var tmpDire = {
restrict: 'A',
link: function(mScope, mElement, mAttrs){
mElement.bind('click', function (event) {
mElement[0].disabled = true;
$interval(function () {
mElement[0].disabled = false;
}, 3000);
})
}
};
