目前我正在使用 AnularJS 更新 JSON 文件中的值，一旦单击“提交”按钮，我想清除整个 DOM 并刷新 UI 并更新内容。你能在这里帮忙吗
这里 Value1 和 Value2 来自两个不同的函数，但有时 . Value2 将为空，并且仅存在 Value1。但单击提交按钮后，Value2 仍将显示为旧值，Value1 仍将显示为更新值。
AngularJS 有没有办法在更新值之前刷新 DOM。这样一旦我点击提交我应该只看到 Value1
var app = angular.module('myApp', ['angular-loading-bar']);
app.controller("Controller", ["$scope", "$http", "$window",
function ($scope, $http, $window) {
$scope.firstFunction = function () {
$http({
method: 'POST',
url: 'one.php',
//headers : {'Content-Type':'application/x-www-form-urlencoded'},
data: {
"accountnumber": $scope.accountnumber,
"environment": $scope.selectedVal,
},
}).then(function (response) {
var data = response.data;
$scope.post = response.data;
$scope.value1 = response.data
//$scope.secondFunction(data);
}, function (error) {
var data = error.data;
console.log("Error" + data);
})
}
$scope.secondFunction = function () {
$http({
method: 'POST',
url: 'two.php',
//headers : {'Content-Type':'application/x-www-form-urlencoded'},
data: {
"accountnumber": $scope.accountnumber,
"environment": $scope.selectedVal,
},
}).then(function (response) {
var data = response.data;
$scope.post = response.data;
$scope.value2 = response.data
console.log($scope.cellularIPAddressValue);
//$scope.secondFunction(data);
}, function (error) {
var data = error.data;
console.log("Error" + data);
})
}
}

无需刷新 UI，因为 Angular 数据绑定(bind)即可完成这项工作。
更改ng-click="firstFunction();secondFunction();"
到 ng-click="value1=null;value2=null;firstFunction();secondFunction();" 可能会有所帮助。
