我正在尝试在文本框中找到重复值，检查ng-change上的每个输入值。然后显示消息“sos number有匹配”。但是仍然按顺序排序生成列表数据。结果，定期留言jsfiddle 到目前为止，我没有成功。以下是代码。 ：
html代码：
<form name="settingForm" ng-submit="mangeDeviceSettings()"><div class="form-group">
<div data-ng-repeat="i in sosLength track by $index">
<ng-form name="sosNumForm">
<span class="input-icon"> <input type="text" ng-disabled="!showPendingStatus" watch-change="change()"
class="form-control" name="SOSNumber" ng-minlength="10" ng-maxlength="13" placeholder="SOSNumber{{$index+1}} No." ng-pattern="/^[0-9]+$/"
ng-model="deviceSettings.sos[$index]" ng-change="sosChange($index,this)">
<i class="fa fa-mobile"></i></span>
<span ng-show="IsMatch{{$index}} && sampleSOS && sosNumForm.SOSNumber.$dirty">SOS Number has a match!</span>
<span ng-show="(sosNumForm.SOSNumber.$error.minlength || sosNumForm.SOSNumber.$error.maxlength) && sosNumForm.SOSNumber.$dirty">Mobile Number must be between 10 and 13 digits </span>
<span ng-show="!sosNumForm.SOSNumber.$error.minlength && !sosNumForm.SOSNumber.$error.maxlength && sosNumForm.SOSNumber.$error.pattern && sosNumForm.SOSNumber.$dirty">Number must contain only numbers</span>
</ng-form>
</div>
</div>
</div></form>
ng-change method：
$scope.sosChange=function(idx, obj){
$scope.sampleSOS = true;
$scope.fnfDuplicate=true;
obj.$parent.settingForm.$valid = obj.sosNumForm.$valid;
// console.log(obj.$parent.settingForm.$valid);
// console.log(obj.sosNumForm.$valid);
console.log($scope.deviceSettings.sos[idx]);
console.log($scope.deviceSettings.sos[i] );
// console.log(obj.sosNumForm.$valid);
// console.log($scope.deviceSettings.sos[idx]!="");
for (var i = 0; i < 3; i++) {
if(idx != i ){
if ($scope.deviceSettings.sos[idx] == $scope.deviceSettings.sos[i]
&& obj.sosNumForm.$valid && $scope.deviceSettings.sos[idx]!="") {
if(idx==0){
$scope.IsMatch0=true; $scope.sosDuplicate=true;
return false;
}
if(idx==1){
$scope.IsMatch1=true; $scope.sosDuplicate=true;
return false;
}
if(idx==2){
$scope.IsMatch2=true; $scope.sosDuplicate=true;
return false;
}
}
else{
if(idx==0){
$scope.IsMatch0=false; $scope.sosDuplicate=false;
return false;
}
if(idx==1){
$scope.IsMatch1=false; $scope.sosDuplicate=false;
return false;
}
if(idx==2){
$scope.IsMatch2=false; $scope.sosDuplicate=false;
return false;
}
}
// $scope.sosDuplicate=true;
}
}
}

如果我理解正确你只是想要验证两个字段具有相同的值...如密码和确认密码...我会粘贴一个片段（密码和确认密码），但从那里我相信你能得到你需要的东西
我也没有看到需要ngChange，因为这两个项目都在范围内，因此如果它们不相等，你只想进行验证。
<div class="form-group required" ng-class="{ 'has-error' : changePasswordForm.password.$invalid && submitted}">
<label class="col-md-3 control-label">New Password </label>
<div class="col-md-8">
<input class="form-control" name="password" ng-model="user.password" ng-minLength="6" type="password" required>
<p ng-show="changePasswordForm.password.$error.minlength && submitted" class="help-block">Password must be atleast 6 characters long.</p>
<p ng-show="changePasswordForm.password.$error.required && !changePasswordForm.password.$error.minlength && submitted" class="help-block">Password is required.</p>
</div>
</div>
<div class="form-group required" ng-class="{ 'has-error' : (changePasswordForm.confPassword.$invalid || user.password!== user.confPassword) && submitted}">
<label class="col-md-3 control-label">Confirm password </label>
<div class="col-md-8">
<input class="form-control" name="confPassword" ng-model="user.confPassword" type="password" required>
<p ng-show="changePasswordForm.confPassword.$invalid && submitted" class="help-block">This field is required.</p>
<p ng-show="changePasswordForm.confPassword.$valid && user.password!== user.confPassword && submitted" class="help-block">Passwords must match.</p>
</div>
</div>
并提交用于检查提交时间...不是必需的
所以在这里你看我们检查两个范围项是否不相等，因此我们显示错误......
控制器中的只需
$scope.onSubmit = function () {
$scope.submitted = true;
if ($scope.createProfileForm.createUserForm.$valid && $scope.user.password === $scope.user.confPassword) {
$scope.submitted = false;
}
}
