我在angularjs html结构中有两个输入框。
当我单击按钮或标签时，我希望我的文本框的angularjs中的新旧值相同，或者我想比较旧值与新旧值是否相同。
我正在使用角度1.4.7。
<input phone-input ng-show="mode == 'edit'" ng-model="leader.work"/>
<input phone-input ng-show="mode == 'edit'" ng-model="leader.mobile"/>
<a ng-show="mode == 'edit'" ng-click="mode = null;save_profile(leader)" style="cursor: pointer" title="Save">Save</a>
$scope.save_profile = function (leader) {
/* How to get/compare both text box old and new value are same or not*/
};
最佳答案
尝试这个
function TodoCrtl($scope) {
$scope.newValue = 'Initial Text';
$scope.save_profile = function(newvalue, oldvalue) {
//Here you can access old value and new value from scope.
$scope.new = 'New Value :' + $scope.newValue;
$scope.old = 'Old Value :' + $scope.oldValue;
//After accessing update the scope old value to new value with function parameters
$scope.newValue = newvalue;
$scope.oldValue = newvalue;
};
$scope.changeValue = function() {
$scope.newValue = 'Dynamic Change';
};
