当我的标签srcset
上有属性时<img />
,为什么它不显示在浏览器中?似乎通过 React.js 正在剥离它。
<img src="/images/logo.png" srcset="/images/logo-1.5x.png 1.5x, /images/logo-2x.png 2x" />
解决方案是使用srcSet
而不是srcset
.
<img src="/images/logo.png" srcSet="/images/logo-1.5x.png 1.5x, /images/logo-2x.png 2x" />
参考:https ://facebook.github.io/react/docs/tags-and-attributes.html下HTML Attributes
另一个使用模板文字的丑陋解决方案:
<img
alt=''
src={require('../../assets/images/logo/logo.png')}
srcSet={`
${require('../../assets/images/logo/logo@2x.png')} 2x,
${require('../../assets/images/logo/logo@3x.png')} 3x
`}
/>
尝试使用带有字符串的 srcSet 可能对我不起作用,可能是因为 Webpack 的工作方式最终如此,导入它们并将它们包含在模板字符串中,如下一个示例所示:
import nat1 from "./img/nat-1.jpg";
import nat1Large from "./img/nat-1-large.jpg";
import nat2 from "./img/nat-2.jpg";
import nat2Large from "./img/nat-2-large.jpg";
import nat3 from "./img/nat-3.jpg";
import nat3Large from "./img/nat-3-large.jpg";
<div className="composition">
<img
srcSet={`${nat1} 300w, ${nat1Large} 1000w`}
sizes="(max-width: 56.25em) 20vw, (max-width: 37.5em) 30vw, 300px"
alt="Photo 1"
className="composition__photo composition__photo--p1"
src={nat1Large}
/>
<img
srcSet={`${nat2} 300w, ${nat2Large} 1000w`}
sizes="(max-width: 56.25em) 20vw, (max-width: 37.5em) 30vw, 300px"
alt="Photo 2"
className="composition__photo composition__photo--p2"
src={nat2Large}
/>
<img
srcSet={`${nat3} 300w, ${nat3Large} 1000w`}
sizes="(max-width: 56.25em) 20vw, (max-width: 37.5em) 30vw, 300px"
alt="Photo 3"
className="composition__photo composition__photo--p3"
src={nat3Large}
/>
</div>
