ng-options with disabled rows

Question

Is it possible to use ng-options that it will render into disabled rows based on criteria?

this:

 <select ng-options="c.name group by c.shade for c in colors">

maybe possible to turn into something like this:

 <select ng-options="c.name group by c.shade for c in colors | disabled(c.shade)">

and let's say via a filter that could return disabled='disabled' for all the colors that have shade = "dark"

<select>
   <optgroup label="dark">
      <option value="0" disabled="disabled">black</option>
      <option value="2" disabled="disabled">red</option>
      <option value="3" disabled="disabled">blue</option>
   </optgroup>
   <optgroup label="light">
      <option value="1">white</option>
      <option value="4">yellow</option>
   </optgroup>
 </select>

Answer 1

@lucuma's answer (originally the accepted answer) was correct, but by now should be updated, because this was fixed in Angular 1.4. See the docs of ng-options which also contains an example.

I'm using Angular 1.5 and this works for me:

View

<select ng-model="$ctrl.selectedItem" ng-options="item as item.label disable when item.disabled for item in $ctrl.listItems">

Controller

vm.items = [ { id: 'optionA', label: 'Option A' }, { id: 'optionB', label: 'Option B (recommended)' }, { id: 'optionC', label: 'Option C (Later)', disabled: true } ]; vm.selectedItem = vm.items[1];

Answer 2

As pointed by @Lod Angular added support for this in 1.4.0-beta.5.

For angular js >= 1.4.0-beta.5.

<select ng-options="c.name disable when c.shade == 'dark' 
group by c.shade for c in colors">

And for angular js < 1.4.0-beta.5 refer the solution below:

Similar to the one given by @lucuma but without jQuery dependency.

Check this http://jsfiddle.net/dZDLg/46/

Controller

<div ng-controller="OptionsController">
    <select ng-model="selectedport" 
        ng-options="p.name as p.name for p in ports"
        options-disabled="p.isinuse for p in ports"></select>
    <input ng-model="selectedport">
</div>

Directive

angular.module('myApp', [])
.directive('optionsDisabled', function($parse) {
    var disableOptions = function(scope, attr, element, data, 
                                  fnDisableIfTrue) {
        // refresh the disabled options in the select element.
        var options = element.find("option");
        for(var pos= 0,index=0;pos<options.length;pos++){
            var elem = angular.element(options[pos]);
            if(elem.val()!=""){
                var locals = {};
                locals[attr] = data[index];
                elem.attr("disabled", fnDisableIfTrue(scope, locals));
                index++;
            }
        }
    };
    return {
        priority: 0,
        require: 'ngModel',
        link: function(scope, iElement, iAttrs, ctrl) {
            // parse expression and build array of disabled options
            var expElements = iAttrs.optionsDisabled.match(
                /^\s*(.+)\s+for\s+(.+)\s+in\s+(.+)?\s*/);
            var attrToWatch = expElements[3];
            var fnDisableIfTrue = $parse(expElements[1]);
            scope.$watch(attrToWatch, function(newValue, oldValue) {
                if(newValue)
                    disableOptions(scope, expElements[2], iElement, 
                        newValue, fnDisableIfTrue);
            }, true);
            // handle model updates properly
            scope.$watch(iAttrs.ngModel, function(newValue, oldValue) {
                var disOptions = $parse(attrToWatch)(scope);
                if(newValue)
                    disableOptions(scope, expElements[2], iElement, 
                        disOptions, fnDisableIfTrue);
            });
        }
    };
});

Note: This solution doesn't work with group by as rightly pointed by everyone. Refer the solution below by @DHlavaty if you are looking to make it work with group by.

Angular added support for this in 1.4.0-beta.5

<select ng-options="c.name disable when c.shade == 'dark' group by c.shade for c in colors">

Answer 4

I do not believe there is a way to do what you are asking just using ng-options. This issue was raised on the angular project and is still open:

https://github.com/angular/angular.js/issues/638

It seems that the work around is to use a directive which is referenced here and in the github issue: http://jsfiddle.net/alalonde/dZDLg/9/

Here is the entire code from the jsfiddle for reference (the code below is from alande's jsfiddle):

<div ng-controller="OptionsController">
    <select ng-model="selectedport" 
        ng-options="p.name as p.name for p in ports"
        options-disabled="p.isinuse for p in ports"></select>
    <input ng-model="selectedport">
</div>

angular.module('myApp', [])
.directive('optionsDisabled', function($parse) {
    var disableOptions = function(scope, attr, element, data, fnDisableIfTrue) {
        // refresh the disabled options in the select element.
        $("option[value!='?']", element).each(function(i, e) {
            var locals = {};
            locals[attr] = data[i];
            $(this).attr("disabled", fnDisableIfTrue(scope, locals));
        });
    };
    return {
        priority: 0,
        require: 'ngModel',
        link: function(scope, iElement, iAttrs, ctrl) {
            // parse expression and build array of disabled options
            var expElements = iAttrs.optionsDisabled.match(/^\s*(.+)\s+for\s+(.+)\s+in\s+(.+)?\s*/);
            var attrToWatch = expElements[3];
            var fnDisableIfTrue = $parse(expElements[1]);
            scope.$watch(attrToWatch, function(newValue, oldValue) {
                if(newValue)
                    disableOptions(scope, expElements[2], iElement, newValue, fnDisableIfTrue);
            }, true);
            // handle model updates properly
            scope.$watch(iAttrs.ngModel, function(newValue, oldValue) {
                var disOptions = $parse(attrToWatch)(scope);
                if(newValue)
                    disableOptions(scope, expElements[2], iElement, disOptions, fnDisableIfTrue);
            });
        }
    };
});

function OptionsController($scope) {
    $scope.ports = [{name: 'http', isinuse: true},
                    {name: 'test', isinuse: false}];

    $scope.selectedport = 'test';
}

Answer 5

Since February 2015 there has been a way to disable options in your ng-options tag.

This Link shows the addition of the feature on github

I found that using angular 1.4.7, the syntax had changed from 'disable by' to 'disable when'.

The syntax for this is:

'ng-options': 'o.value as o.name disable when o.unavailable for o in options'

Answer 6

A similar effect can be achieved using ng-repeat and ng-disabled on the option itself, avoiding the use of a new directive.

HTML

<div ng-controller="ExampleController">
    <select ng-model="myColor">
        <option ng-repeat="c in colors" ng-disabled="c.shade=='dark'" value="{{$index}}">
            {{c.name}}
        </option>
    </select>
</div>

Controller

function ExampleController($scope, $timeout) {
    $scope.colors = [
      {name:'black', shade:'dark'},
      {name:'white', shade:'light'},
      {name:'red', shade:'dark'},
      {name:'blue', shade:'dark'},
      {name:'yellow', shade:'light'}
    ];
    $timeout(function() {
        $scope.myColor = 4; // Yellow
    });
}

Fiddle

http://jsfiddle.net/0p4q3b3s/

Known issues:

• Does not use ng-options
• Does not work with group by
• Selects the index, not the object
• Requires $timeout for initial selection

Edit : Any object property can be selected (besides the index), but not the object itself. Also, if you have a simple array and not an array of objects, below method will work.

Change this line in HTML :

<option ng-repeat="c in colors" ng-disabled="c.shade=='dark'" value="{{c.name}}">

Change this line in Controller :

$scope.myColor = $scope.colors[4].name; // Yellow

Answer 7

I had an interesting situation. An array of dropdowns and I need it to disable the options that were already selected in each of the dropdowns, but I also need it to keep enable the one that was selected already...

here is my plunker: Enable/Disable values with ng-options

var app = angular.module('ngoptions', []);

app.controller('MainCtrl', function($scope) {

  // disable the fields by default
  $scope.coverage = [
    { CoverageType: '', CoverageName: 'No Coverage' },
    { CoverageType: 'A', CoverageName: 'Dependent Only' },
    { CoverageType: 'B', CoverageName: 'Employee Plus Children' },
    { CoverageType: 'C', CoverageName: 'Employee Only' },
    { CoverageType: 'D', CoverageName: 'Employee Plus One' },
    { CoverageType: 'E', CoverageName: 'Employee Plus Two' },
    { CoverageType: 'F', CoverageName: 'Family' },
];
            
            
  // values already set ex: pulled from db          
  $scope.rates = ['A','C', 'F'];     

  $scope.changeSelection = function (index, rate){
     $scope.rates[index] = rate;
     disableRecords();
  }
  
  // start by disabling records
  disableRecords(); 
  
  function disableRecords () {
      // set default values to false
      angular.forEach($scope.coverage, function (i, x) {
             i.disable = false; 
      });
      // set values to true if they exist in the array
      angular.forEach($scope.rates, function (item, idx) {
          angular.forEach($scope.coverage, function (i, x) {
              if (item == i.CoverageType) {
                   i.disable = true; 
              }
          });
      });
  }
  

});

You can disable using ngOptions in angular 1.4.1 or above

HTML template

<div ng-app="myapp">
<form ng-controller="ctrl">
    <select id="t1" ng-model="curval" ng-options='reportingType.code as reportingType.itemVal disable when reportingType.disable for reportingType in reportingOptions'>
        <option value="">Select Report Type</option>
    </select>

</form>

Controller code

angular.module('myapp',[]).controller("ctrl", function($scope){
$scope.reportingOptions=[{'code':'text','itemVal':'TEXT','disable':false}, {'code':'csv','itemVal':'CSV','disable':true}, {'code':'pdf','itemVal':'PDF','disable':false}];

})

Answer 9

Similar "without jQuery" solution as @Vikas-Gulati's, but it works with group by

In my case, group by doesn't work, because my first <option> was without value, just with Please select and item from dropdown text. This is a slightly modified version, that fixes this particular situation:

Usage is simmilar to @Vikas-Gulati answer: https://stackoverflow.com/a/20790905/1268533

Directive

angular.module('disabledModule', [])
    .directive('optionsDisabled', function($parse) {
        var disableOptions = function(scope, attr, element, data, fnDisableIfTrue) {
            var realIndex = 0;
            angular.forEach(element.find("option"), function(value, index){
                var elem = angular.element(value);
                if(elem.val()!="") {
                    var locals = {};
                    locals[attr] = data[realIndex];
                    realIndex++; // this skips data[index] with empty value (IE first <option> with 'Please select from dropdown' item)
                    elem.attr("disabled", fnDisableIfTrue(scope, locals));
                }
            });
        };
        return {
            priority: 0,
            require: 'ngModel',
            link: function(scope, iElement, iAttrs, ctrl) {
                // parse expression and build array of disabled options
                var expElements = iAttrs.optionsDisabled.match(/^\s*(.+)\s+for\s+(.+)\s+in\s+(.+)?\s*/);
                var attrToWatch = expElements[3];
                var fnDisableIfTrue = $parse(expElements[1]);
                scope.$watch(attrToWatch, function(newValue, oldValue) {
                    if(newValue)
                        disableOptions(scope, expElements[2], iElement, newValue, fnDisableIfTrue);
                }, true);
                // handle model updates properly
                scope.$watch(iAttrs.ngModel, function(newValue, oldValue) {
                    var disOptions = $parse(attrToWatch)(scope);
                    if(newValue)
                        disableOptions(scope, expElements[2], iElement, disOptions, fnDisableIfTrue);
                });
            }
        };
    });

Answer 10

As I cannot upgrade to latest angularJS, so created a simpler directive to handle it.

.directive('allowDisabledOptions',['$timeout', function($timeout) {
    return function(scope, element, attrs) {
        var ele = element;
        var scopeObj = attrs.allowDisabledOptions;
        $timeout(function(){
            var DS = ele.scope()[scopeObj];
            var options = ele.children();
            for(var i=0;i<DS.length;i++) {
                if(!DS[i].enabled) {
                    options.eq(i).attr('disabled', 'disabled');
                }
            }
        });
    }
}])

Answer 11

I also hid disabled options adding fallowing line:

$(this).css("display", fnDisableIfTrue(scope, locals) ? "none" : "block");

It was necessary as I couldn't simply filter them out, as the initial value of this select could be one of the disabled options.
