1.全局支持 enter快捷键触发事件
// 全局指令
app.directive('ngEnter', ['$window',"$timeout", ($window,$timeout) => {
return {
restrict: 'A',
link ($scope, element, attrs) {
element.bind('keypress', (ev) => {
ev = ev || $window.event;
if (event.keyCode === 13) {
$timeout(function () {
$scope.$eval(attrs.ngEnter);
});
//引入$timeout 解决渲染问题
ev.preventDefault ? ev.preventDefault() : ev.returnValue = false;
return false;
}
$window.event ? ev.cancelBubble=true : ev.stopPropagation();//清除冒泡
});
element.on('$destroy', function () {
element.unbind('keypress');
$scope.$destroy();
});
}
};
}]);
2.点击按钮之后禁用按钮，防止多重提交
app.directive('clickAndDisable', function() {
return {
scope: {
clickAndDisable: '&'
},
link: function(scope,element, iAttrs) {
element.bind('click', function() {
element.prop('disabled',true);
scope.clickAndDisable().finally(function() {
element.prop('disabled',false);
})
});
}
};
});
3.判断 ng-repeat 渲染完成后操作
app.directive('repeatFinish',function(){
return {
link: function(scope,element,attr){
if(scope.$last == true){
console.log("ng-repeat遍历完成");
scope.$eval( attr.repeatFinish )
}
}
}
});
