How to create a directive for disable all elements into div element

how to create a directive for disable all elements into div element ?

something like this :

<div div-disabled div-disabled-condition="state=='Stack'||state=='Over'||state=='Flow'">
  <input type="text"/>
  <input type="url"/>
  <div>
    <input type="text"/>
    <input type="url"/>
  </div>
<div>

Is it possible? I have no idea .

     angular
    .module('uiRouterApp.ctrl.add', ['uiRouterApp.ctrl.customDirective'])
    .controller('addCtrl', [
        '$scope',
        '$location',
        '$stateParams',
        '$state',
        function ($scope, $location, $stateParams, $state) {
            $scope.state = {};
         }
    ]).directive('divDisabled', function () {
        return {
        scope: {
              divDisabledCondition: '@'
             },
            link: function (scope, element, attrs) {

            }
        };
    });

Update :

please see this :

   <div class="col-sm-12 ng-isolate-scope" selected-object="SelectedAutoComplete" local-data="requirements.Item1" search-fields="NameFa,NameEn" title-field="NameFa" minlength="2" field-required="true" image-field="ImageUrl" disable-auto-compelete="response.State=='Success'||response.State=='Error'||response.State=='Warning'">

<div class="angucomplete-holder">
  <input id="_value" ng-model="searchStr" type="text" placeholder="select" class="form-control ng-dirty" ng-focus="resetHideResults()" ng-blur="hideResults()" autocapitalize="off" autocorrect="off" autocomplete="off" ng-change="inputChangeHandler(searchStr)" ng-disabled="response.State=='Success'||response.State=='Error'||response.State=='Warning'" style=""> 

  <!-- ngIf: showDropdown -->
  </div>
  </div>

directive :

.directive('contentsDisabled', function() {
        return {
            compile: function(tElem, tAttrs) {
                var inputs = tElem.find('input');
                for (var i = 0; i < inputs.length; i++) {
                    inputs.attr('ng-disabled', tAttrs['disableAutoCompelete']);
                }
            }
        }
    })

why When the state is 'Success' or 'Error' or 'Warning' Input not disabled ?

回答1:

You can create a directive that alters its content during compile time by adding the condition. Something along these lines (untested):

module.directive('contentsDisabled', function() {
  return {
    compile: function(tElem, tAttrs) {
      var inputs = tElem.find('input');
      inputs.attr('ng-disabled', tAttrs['contentsDisabled']);
    }
  };
});

See a JSFiddle here: http://jsfiddle.net/HB7LU/6380/

This has the drawback that you just copy the expression from contents-disabled into ng-disabled attributes of any inputs - if somebody uses a directive that in turn creates <input> elements, you won't pick them up.

It'd be less fragile to get hold of the FormController instance and iterate through all its controls, but sadly AngularJS doesn't expose the controls in a form. Maybe file a feature request?

回答2:

You also can use a tag fieldset :

<form>
    <fieldset ng-disable="foo">
        <input name="the_one"/>
        <input name="the_second"/>
    </fieldset>
    <input name="the_thrid"/>
</form>

With this way, when the variable foo is TRUE, inputs "the_one" and "the_second" will be disabled.

回答3:

Why don't you use ng-disabled on your required expression on each input?

https://docs.angularjs.org/api/ng/directive/ngDisabled

If you truly do want a grouping directive, use the compile function of the directive to insert the ng-disabled attribute on each child. Or use a paren't child directive to signify which children to apply the ng-disabled to.

There is a new option to control enable/disable input field for angucomplete-alt. http://ghiden.github.io/angucomplete-alt/#example13
