推荐答案
ng-if
仅限于 'A'
.所以只能作为属性使用,不能在注释中使用这里是ngIf的angularjs代码
ng-if
is restricted to 'A'
. so it can be used only as attribute, you can't use in comment Here's the angularjs code for ngIf
var ngIfDirective = ['$animate', function($animate) {
return {
transclude: 'element',
priority: 600,
terminal: true,
restrict: 'A', // --> This means restricting to Attribute
restrict
选项通常设置为:'E'
,'A'
,'C'
,'M'
The restrict
option is typically set to: 'E'
,'A'
,'C'
,'M'
EACM
之一将指令限制为特定的指令声明样式.如果您不限制任何,则使用默认值(元素和属性)
.
One of EACM
restricts the directive to a specific directive declaration style. If you don't restrict any, the defaults (elements and attributes) are used
.
E
- 元素名称(默认):
E
- Element name (default): <my-directive></my-directive>
A
- 属性(默认):<div my-directive="exp"></div>
C
- 类:<div class="my-directive: exp;"></div>
M
- 注释:<!-- 指令:my-directive exp -->
