# cssfilter
|
||||
Sanitize untrusted CSS with a configuration specified by a Whitelist. 根据白名单过滤CSS
|
||||
|
||||
|
||||
## 安装
|
||||
|
||||
```bash
|
||||
$ npm install cssfilter --save
|
||||
```
|
||||
|
||||
|
||||
## 使用方法
|
||||
|
||||
```javascript
|
||||
var cssfilter = require('cssfilter');
|
||||
var css = cssfilter('position:fixed; /* this is comments */ width:100px; height:100px; background:#aaa;');
|
||||
console.log(css);
|
||||
// 输出：width:100px; height:100px; background:#aaa;
|
||||
// 因为position不在白名单允许范围
|
||||
```
|
||||
|
||||
或者：
|
||||
|
||||
```javascript
|
||||
options = {
|
||||
// 白名单，可选
|
||||
whiteList: {
|
||||
a: true, // true表示允许
|
||||
b: /^fixed|relative$/, // 正则test()返回true表示允许
|
||||
c: function (value) {
|
||||
// 返回true表示允许
|
||||
},
|
||||
d: false // 除以上三个以外，所有值均表示不允许
|
||||
},
|
||||
// 当匹配到一个在白名单中的属性时
|
||||
onAttr: function (name, value, options) {
|
||||
// name为属性名
|
||||
// value为属性值
|
||||
// 返回字符串表示覆盖此段CSS
|
||||
// 不返回任何值表示使用默认生成方法，即 name:value
|
||||
},
|
||||
// 当匹配到一个不在白名单中的属性时
|
||||
onIgnoreAttr: function (name, value, options) {
|
||||
// name为属性名
|
||||
// value为属性值
|
||||
// 返回字符串表示覆盖此段CSS
|
||||
// 不返回任何值表示使用默认生成方法，即将此段CSS去掉
|
||||
}
|
||||
};
|
||||
mycss = new cssfilter.FilterCSS(options);
|
||||
// then apply mycss.process()
|
||||
css = mycss.process('position:fixed; width:100px; height:100px; background:#aaa;');
|
||||
console.log(css);
|
||||
