Answer 1

如果要按属性值过滤ng-repeat中的数组，则需要向ng-model指明要过滤的属性：

<input type="text" ng-model="buscaralumno.Nota" >

下拉列表应该表示如下：

<tr ng-repeat="Alumno in lsalumnos.ALUMNOS | filter:buscaralumno">

Answer 2

如果我知道您希望下拉列表选择要过滤的属性（Nota或Codigo），则需要使用自定义过滤功能。

类似的东西：

$scope.parametroFilter = function(input){
    return (input[$scope.parametro].indexOf($scope.buscaralumno) != -1);
};

并使用如：

<tr ng-repeat="Alumno in lsalumnos.ALUMNOS | filter:parametroFilter">

或者，您可以使用函数返回动态过滤器对象：

$scope.getParametroFilter = function(){
    var filter = {};
    filter[$scope.parametro] = $scope.buscaralumno;
    return filter;
};

并使用如：

<tr ng-repeat="Alumno in lsalumnos.ALUMNOS | filter:getParametroFilter()">

根据下拉列表按文字进行角度过滤
