如下：
readonly="expression"

expression中如何根据控制器来获得呢，

if($scope.index == “0”){ $scope.ifReadOnly=function(){ return false; } }else{ $scope.ifReadOnly=function(){ return true; } }

readonly="expression" 写成readonly="ifReadOnly（）"不可以的。

如何修改才能让readonly根据expression不同的值去产生作用呢？

Let’s do this:

$scope.$watch('index', function(newIndex){ $scope.ifReadOnly = newIndex !== '0'; });

    html:

    js:

    // 默认值 $scope.demo = { readOnly: true }; $scope.handleRead = function () { if ($scope.demo.readOnly) { // todo readonly } else { // todo not readonly } };
