模板过滤器 - addslashes


示例

转义 name 变量中的引号

<h1>{{ name|addslashes }}</h1>
运行示例 »

定义和用法

addslashes 过滤器在任何引号之前添加反斜杠 \ 字符。

当您处理 JavaScript 并必须转义引号字符时,这很有用。

示例

转义 name,否则在警示它时会出错

<button onclick="alert('{{ name|addslashes }}')">Click me!</button>
运行示例 »

如果没有上述示例中的 addslashes 过滤器,当有人点击按钮时,页面会出错。


语法

模板过滤器通过使用管道 | 字符后跟过滤器的名称来定义。

{{ value|addslashes }}
