ng-bind:使用双冒号连接两个值

Question

ng-bind当两个冒号用双冒号连接时,我们如何使用？

<title ng-bind="::AppConfig.SITE_TITLE + ::AppConfig.PAGE_TITLE"></title>

上面的代码返回此错误:

Error: [$parse:syntax] Syntax Error: Token ':' not a primary expression at column 24 of the expression [AppConfig.SITE_TITLE + ::AppConfig.PAGE_TITLE] starting at [::AppConfig.PAGE_TITLE].

请注意,这工作正常:

<title ng-bind="::AppConfig.SITE_TITLE + ' | This is page title'"></title>

Answer 1

尝试: <title ng-bind="::(AppConfig.SITE_TITLE + AppConfig.PAGE_TITLE)"></title>
