.controller("MyController", function($scope, $http) {
$scope.myData = {};
$scope.myData.doClick = function(item, event) {
var responsePromise = $http.get("https://ajith-indian-mob-info.p.mashape.com/getInfo?mobno="+item, {headers: {'X-Mashape-Key': ''}});
responsePromise.success(function(data, status, headers, config) {

嗨,我是angular的新手,如何從文本框中獲取值到controller angular?
我在控制器中親自定義了對象用戶(為了更好地閱讀,這不是必需的)
$scope.user = {}
然后
<input type="number" class="form-control" ng-model="user.phonenum" name="phonenum" id="inputSuccess2">
會自動將此文本框的內容綁定到變量$scope.user.phonenum
,您可以輕松地訪問它:
$scope.myData.doClick = function() {
var responsePromise = $http.get("https://ajith-indian-mob-info.p.mashape.com/getInfo?mobno="+$scope.user.phonenum, {headers: {'X-Mashape-Key': ''}});
...
您可以使用$scope.ModelName
在控制器的范圍內獲取模型的值。
在任何需要電話號碼的位置執行此$scope.user.phonenum
但是,請檢查模型是否在控制器的范圍內。
使用Angular,您應該改變思維方式,在控制器中不使用視圖...使用模型(並讓指令更新該模型)。 因此,在您的示例中,文本框已映射到user.phonenum,因此您可以在控制器中執行類似$ scope.user.phonenum的操作。
