如何使用angular.js禁用输入框

Question

我正在使用此字段进行编辑视图和创建视图

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

在控制器中我有这个代码来禁用输入元素:

function($rootScope, $scope, $location, userService)
{

//etc 
    $(".editEmail" ).attr("disabled", disable);  // no idea how to do in angular
}

请帮忙.

Answer 1

使用ng-disabled或带有ng-class的特殊CSS 类

<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 2

您需要使用ng-disabled指令

<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>" />

我为此创建了一个指令(角度稳定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");
    });
  }
});
