1. AngularJS 表达式的定义 AngularJS 表达式是一种在双大括号{{}}内部使用的轻量级 JavaScript 代码段,用于在视图中动态输出数据。它可以包含变量、函数调用、操作符和过滤器等元素。AngularJS 表达式通过数据绑定实现与应用程序后端数据的交互,使得数据的呈现和更新变得非常简单。 2. AngularJS 表达式的语法 AngularJS...
Angular expressions are generally considered safe because these expressions only have direct access to $scope and locals. However, one can obtain the ability to execute arbitrary JS code by obtaining a reference to native JS functions such as the Function constructor. ...
Scope(作用域): context where the model is stored so that controllers, directives and expressions can access it (存储模型的上下文,可供控制器,指令和表达式调用) Expressions(表达式): access variables and functions from the scope (能从作用域里访问变量和函数) Compiler(编译器): parses the template an...
AngularJS 使用表达式把数据绑定到 HTML。 AngularJS 表达式 AngularJS 表达式写在双大括号内:{{ expression }}。 AngularJS 表达式把数据绑定到 HTML,这与ng-bind指令有异曲同工之妙。 AngularJS 将在表达式书写的位置"输出"数据。 AngularJS 表达式很像JavaScript 表达式:它们可以包含文字、运算符和变量。
AngularJS expressions can be written inside double braces:{{expression}}. AngularJS expressions can also be written inside a directive:ng-bind="expression". AngularJS will resolve the expression, and return the result exactly where the expression is written. ...
