|
A library to easily build DOM objects through the magic of Lua meta tables.
|
|
|
|
# Usage
|
|
|
|
```lua
|
|
-- any HTML tag can be used here
|
|
dom.span {
|
|
-- tag attributes can be set like this:
|
|
class = "my-class",
|
|
id = "my-id",
|
|
-- Plain text body elements can be added like this
|
|
"Span content",
|
|
-- And elements can be nested
|
|
dom.strong { "I am strong" }
|
|
}
|
|
```
|
|
|
|
# Examples
|
|
${widget.html(dom.marquee{
|
|
"I'm in a ",
|
|
dom.span {
|
|
style="color:red;",
|
|
"marquee"
|
|
}
|
|
})}
|
|
|
|
# Implementation
|
|
```space-lua
|
|
dom = setmetatable({}, {
|
|
__index = function(self, tag)
|
|
return function(spec)
|
|
local node = js.window.document.createElement(tag)
|
|
for key, val in pairs(spec) do
|
|
if type(key) == "string" then
|
|
-- This is an attribute
|
|
if key:startsWith("on") then
|
|
node.addEventListener(key:sub(3), val)
|
|
else
|
|
node.setAttribute(key, val)
|
|
end
|
|
elseif type(val) == "string" then
|
|
-- Text body
|
|
node.appendChild(js.window.document.createTextNode(val))
|
|
else
|
|
-- Implicit assumption: this is a DOM node
|
|
node.appendChild(val)
|
|
end
|
|
end
|
|
return node
|
|
end
|
|
end
|
|
})
|
|
```
