title: Attributes.renderIfPrefixIs()
|
||
|
|

|
|
The `Attributes.renderIfPrefixIs()` method will render attributes as a string
|
||
|
|
suitable for inclusion in an SVG tag, but only those attribute keys who start
|
||
|
|
with `prefix`.
|
||
|
|
|
||
|
|
## Signature
|
||
|
|
|
||
|
|
```js
|
||
|
|
string attributes.renderIfPrefixIs(string prefix)
|
||
|
|
```
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
```js
|
||
|
|
const attr = new Attributes()
|
||
|
|
.add('class', 'various')
|
||
|
|
.add('stroke', 'red')
|
||
|
|
.add('stroke-width', 2)
|
||
|
|
|
||
|
|
const line = `<path ${attr.renderIfPrefixIs('stroke')} d="M 0,0 L 100.0" />`
|
||
|
|
```
