Description

I'm submitting a ... bug report

When a class attribute has more than 1 class, the program reports an error.

Expected Results

<div class="a b"> should work

Bug fix

File src/virtual_dom/vtag.rs:

80    pub fn add_classes(&mut self, classes: &str) {
81        let classes = classes.trim().split(" ");
82        for class in classes {
83            let class = class.trim();
84            if !class.is_empty() {
85                self.classes.insert(class.into());
86            }
87        }
88    }

Source code: It expect you input something like: <div class=("a", "b",), >, you can try it without trailing comma to see if it works?? (such as: <div class=("a", "b"), > I don't know 😁 ).

Or maybe we should accept class="a b c", then split them by space and add them, @deniskolodin ? Sorry for the hasty reply (I am not in good mood now, 😁 ), It is the proposal for fixing this by the OP himself, I just came up with the same idea!.

Actually I hate this thing too 😢 I think I have to split string of classes in templates in the nearest PR.
Related #121

1. class="a b c" then split before add: impact on performance as you mention in Can't use spaces directly in a class string #121. But if I remember correctly, it is the prefer way in HTML.
2. class=("a", "b",),: You hate it yourself!
3. In Experiment: shtml! #285 , I think I successfully (it pass the test, and I see the result in browser inspector) implement this syntax: class="a" "b" "c",. This way, it do not impact on performance, less awkward than (2.)

Maybe the solution is:

• Allow both: class="a b c", (with a warn about performance in README?) and class="a" "b" "c",
  then users may choose what they want

I didn't see the related open bug, sorry. The fix I've sent you, doesn't seem to impact compiling time.

Fixed with #289
