angularjs传递参数通过指令和NG重复 [英] angularjs passing parameters through directive and ng-repeat

问题描述

让我们再试一次：

这里的工作plunker：

here's a working plunker: http://plnkr.co/edit/RTrdsLY8ONoeDLPYSFJi?p=preview

但是字段彼此连接。

当你看着DOM：

<input class="form-control ng-pristine ng-valid-maxlength ng-valid-minlength ng-valid ng-valid-required" type="text" name="fieldName" ng-model="fieldName" ng-minlength="3" ng-maxlength="20" required="">
                                                                                                                         ^^^^^^^^^^

当然！所有有NAME =字段名！

of course! All have name="fieldName"!

但是，为什么！？它应该是名字，姓氏和年龄！

But why!? it should be first_name, last_name and age!

是的，有在formField.html模板错误：

Yes, there's a mistake in formField.html template:

 <input class="form-control" type="{{fieldType}}" name="fieldName" ng-model="fieldName" ng-minlength=3 ng-maxlength=20 required/>
                                                       ^^^^^^^^^^^

因此​​，让我们将它变成{{字段名}}。因此form。字段出现的所有......成表格。{{字段名}}

So let's change it into {{fieldName}}. And consequently all occurences of form.fieldName... into form.{{fieldName}}.

嘛，哪里走了红框？

让我们来看看DOM -

Let's look at DOM -

<input class="form-control ng-pristine ng-valid-maxlength ng-valid-minlength ng-valid ng-valid-required" type="text" name="first_name" ng-model="fieldName" ng-minlength="3" ng-maxlength="20" required="">

名称是好的，但现在有错不工作...

name is ok, but now has-error doesn't work...

推荐答案

更新：：您可以使用这样的功能，从模型获取您的PARAMS。 （accroding你的数据结构）

Update: You can use a function like this to fetch your params from model. (accroding to your data structure)

另一个分叉plunker： http://plnkr.co/edit/mdKBoEffoUo2ilH7Jd3L?p = preVIEW

Another forked plunker: http://plnkr.co/edit/mdKBoEffoUo2ilH7Jd3L?p=preview

$scope.getModels = function(items) {
  var params = {};

  if (angular.isArray(items)) {
    for (var i = 0; i < items.length; i++) {
      var item = items[i];

      if(angular.isArray(item.fields)) {
        for (var j = 0; j < item.fields.length; j++) {
          var field = item.fields[j];
          params[field.id] = field.model;
        }
      }
    }
  }

  alert(JSON.stringify(params, '', 4));
};

由于动态输入名称尚未这里尚未实施（ Relatived PR ），我插入一个嵌套的 NG-形式 进行验证。而且因为如此，我认为你必须要管理形式使用submittion自己 ngModel 。

在这里检查分叉〔实施例： http://plnkr.co/edit/8cP5YMKUGu6LfBCsRxAZ p = preVIEW

模板：

<div class="form-group" ng-form="form" ng-class="{true: 'has-error', false: 'has-success'}[form.fieldName.$invalid]">
    <label class="control-label col-sm-2" for="fieldName">{{fieldLabel}}</label>
    <div class="col-sm-6">
      <input class="form-control" type="{{fieldType}}" placeholder="enter valid name" name="fieldName" ng-model="fieldModel" ng-minlength=3 ng-maxlength=20 required/>
      <span class="help-block">
        <span ng-show="form.fieldName.$error.required">Required field</span>
        <span ng-show="form.fieldName.$error.minlength">Too few chars - min is (6)</span>
        <span ng-show="form.fieldName.$error.maxlength">Too much chars - max is (20)</span>
        &nbsp;
      </span>
    </div>
</div>

HTML

<form-field ng-repeat="field in tabItem.fields" ng-model='field.model'
    field-type="field.type" field-name='field.id' field-label='field.label'>
</form-field>

JS：

KPNDirectives.directive("formField", function () {
    return {
      restrict: 'E',
      scope: {
        fieldModel: '=ngModel',
        fieldType: '=',
        fieldLabel: '=',
        fieldName: '='
      },
      templateUrl: 'formField.html'
    };   
});
