How to disable an input box using angular.js

Question

I am using this field for an edit view and a create view

Answer 1

You need to use ng-disabled directive

<input data-ng-model="userInf.username" 
       class="span12 editEmail" 
       type="text" 
       placeholder="me@example.com" 
       pattern="[^@]+@[^@]+\.[a-zA-Z]{2,6}" 
       required 
       ng-disabled="<expression to disable>" />

Answer 2

I created a directive for this (angular stable 1.0.8)

<input type="text" input-disabled="editableInput" />
<button ng-click="editableInput = !editableInput">enable/disable</button>

app.controller("myController", function(){
  $scope.editableInput = false;
});

app.directive("inputDisabled", function(){
  return function(scope, element, attrs){
    scope.$watch(attrs.inputDisabled, function(val){
      if(val)
        element.removeAttr("disabled");
      else
        element.attr("disabled", "disabled");
    });
  }
});

<input type="text" input-disabled="editableInput" />
<button ng-click="editableInput = !editableInput">enable/disable</button>

app.controller("myController", function(){
  $scope.editableInput = false;
});

app.directive("inputDisabled", function(){
  return function(scope, element, attrs){
    scope.$watch(attrs.inputDisabled, function(val){
      if(val)
        element.removeAttr("disabled");
      else
        element.attr("disabled", "disabled");
    });
  }
});

Use ng-disabled or a special CSS class with ng-class

<input data-ng-model="userInf.username"  
       class="span12 editEmail" 
       type="text"  
       placeholder="me@example.com"  
       pattern="[^@]+@[^@]+\.[a-zA-Z]{2,6}" 
       required 
       ng-disabled="{expression or condition}"
/>

Answer 5

<input data-ng-model="userInf.username"  class="span12 editEmail" type="text"  placeholder="me@example.com"  pattern="[^@]+@[^@]+\.[a-zA-Z]{2,6}" required ng-disabled="true"/>

Answer 6

Your markup should contain an additional attribute called ng-disabled whose value should be a condition or expression that would evaluate to be either true or false.

    <input data-ng-model="userInf.username"  class="span12 editEmail" 
       type="text"  placeholder="me@example.com"  
       pattern="[^@]+@[^@]+\.[a-zA-Z]{2,6}" 
       required 
       ng-disabled="{condition or expression}"
/>

And in the controller you may have some code that would affect the value of ng-disabled directive.
