#4 Images with Unsafe URLs (Umlauts etc.)
RazorBlade Fluent Tag API @Tag.Img().Src(...)
and Srcset(...)
v3
One of the magic bits of the Html5 tags is that they are smart. For example, url properties like Src()
or Href()
will safely encode if they are not yet encoded.
This is super important for CMS solutions where the image file may easily contain umlaut characters or spaces.
Note that it's Srcset()
and not SrcSet
. For consistency, everything is always lower case.
Initial Code
The following code runs at the beginning and creates some variables/services used in the following samples.
@{
// demo of path with umlauts and japanese characters
var kaizenUrl = "überschrift-small.png?name=改善";
var path = App.Path + "/blade/assets/tag-img/";
var kaizenFullPath = path + kaizenUrl;
var kaizenFullHd = kaizenFullPath.Replace("small", "large");
}
This file is called überschrift-small.png?name=改善
Output
@Tag.Img().Src(kaizenFullPath)
Output
<img src='/Portals/tutorials/2sxc/Tutorial-Razor/blade/assets/tag-img/%C3%BCberschrift-small.png?name=%E6%94%B9%E5%96%84'>
<pre>@Tag.Img().Src(kaizenFullPath).ToString()</pre>
And now the same thing with
Srcset
which allows high-density images:
Output
@Tag.Img().Srcset(kaizenFullPath, 1).Srcset(kaizenFullHd, 2)
