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...
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。实例{{ 5 + 5 }} 或 {{ firstName + " " + lastName }}...
Expressions 表达式: 访问Scope中的variables和functions Compiler 编译器: 解析模版template,实例化指令directives和表达式expressions Filter 过滤器: 把一个表达式expression的值按照一定的格式展示给用户; View 视图: 用户看到的。(也可以叫HTML DOM) Data Binding 数据绑定: 同步模型Model和视图View中的数据。
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. ...
