当我点击按钮时，使用AngularJs在浏览器中显示从SQL Server获取的表数据。我试过返回表数据，但它没有绑定。我需要桌子展示。请提前帮助我
var app = angular.module("myApp", []);
app.controller("myCntrl", function ($scope, $http) {
$scope.fillList = function () {
$scope.RoleName = "";
var httpreq = {
method: 'POST',
url: 'WebForm1.aspx?Meth=GL',
headers: {
'Content-Type': 'application/json; charset=utf-8',
'dataType': 'json'
},
data: {}
}
$http.get("WebForm1.aspx?Meth=GL")
.then(function (response) {
$scope.RolesList = response.data;
});
};
$scope.fillList();
$scope.click = function () {
alert("hi");
var _reqObj = new Object();
_reqObj.Name = $scope.dropdown;
_reqObj.Meth = "PD";
$.ajax({
method: 'POST',
url: 'WebForm1.aspx',
data: _reqObj,
success: function (response) {
$scope.Users =response.data;
}
});
}
});
