input type="text" ng-model="searchText" / button ng-click="check(searchText)" Check! /button {{ searchText }}
在controller中
$scope.check = function (searchText) { console.log(searchText); }
方式二:
引用stackoverflow的一句话,
“If you use ng-model, you have to have a dot in there.” Make your model point to an object.property and you'll be good to go.
在html中,
input ng-model="formData.searchText"/ button ng-click="check()" Check! /button
在controller中,
$scope.formData = {}; $scope.check = function () { console.log($scope.formData.searchText.$modelValue); }
但是我们常常会对ngModel当中的值进行验证,例如,
input type="password" pattern="[0-9]*" placeholder="请输入6位新密码" ng-model="password.new_password" ng-blur="validateLength()"
input type="password" ng-model="password.new_password" ng-keyup="compare(password)" name="repassword" ng-pattern="/^[0-9]{1,6}$/" /
发现ngModel当中的password.new_password不能实时绑定到controller中,原因为ngModel的值并没有符合pattern的规则。若符合规则,则正常绑定传递。
以上这篇Angularjs之ngModel中的值验证绑定方法就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持凡科。
