Parents
SVG.Parent
The SVG.Parent
class is the base wrapper for all elements that can contain other elements. SVG.Parent
inherits directly from the lowest level of all SVG.js classes: SVG.Element
.
SVG.Container
SVG.Container
adds another level to the parent inheritance stack. Where SVG.Parent
brings some low level methods like add()
, remove()
and has()
to name a few, SVG.Container
can and should be used if you want to add your own methods. That way the SVG.Parent
prototype remains clean. Therefore you should always inherit from SVG.Container
when implementing your own parent elements.
The parent inheritance stack is: SVG.Element
> SVG.Parent
> SVG.Container
.
SVG.Doc
The main SVG.js initializer function creates a root svg node in the given element and returns an instance of SVG.Doc
.
SVG() constructor
returns
SVG.Doc
which inherits from
SVG.Container
var draw = SVG('drawing')
Note: The first time SVG()
is called, a second, invisible <svg>
will be created. This is our parser as explained in the FAQ.
SVG.Nested
Nest SVG documents within each other.
nested() constructor
constructor on
SVG.Container
returns
SVG.Nested
which inherits from
SVG.Container
Nested SVG documents have exactly the same features as the main, top-level SVG document:
var nested = draw.nested()
var rect = nested.rect(200, 200)
SVG.G
Grouping elements can be useful if you want to transform a set of elements as if it were one. All element within a group, maintain their position relative to the group they belong to.
Note: Groups do not have a geometry of their own, it's inherited from their content. Therefore groups do not listen to x
, y
, width
and height
attributes. If that is what you are looking for, use a nested()
svg instead.
group() constructor
constructor on
SVG.Container
returns
SVG.G
which inherits from
SVG.Container
A group has all the same element methods as the root SVG document:
var group = draw.group()
group.path('M10,20L30,40')
Existing elements from the SVG document can also be added to a group:
group.add(rect)
SVG.Symbol
constructor on
SVG.Container
returns
SVG.Symbol
which inherits from
SVG.Container
Not unlike the group
element, the symbol
element is a container element. The only difference between symbols and groups is that symbols are not rendered. Therefore a symbol
element is ideal in combination with the use
element:
var symbol = draw.symbol()
symbol.rect(100, 100).fill('#f09')
var use = draw.use(symbol).move(200, 200)
SVG.Defs
The <defs>
element is a container for referenced elements. Descendants of a <defs>
node are not rendered directly. The <defs>
node lives in the main <svg>
document and can be accessed with the defs()
method.
defs() constructor
constructor on
SVG.Container
returns
SVG.Defs
which inherits from
SVG.Container
var defs = draw.defs()
The defs are also available on any other element through the doc()
method:
var defs = rect.doc().defs()
The defs node works exactly the same as groups.
SVG.A
Create a hyperlink that will be activated on all child elements.
link() constructor
constructor on
SVG.Container
returns
SVG.A
which inherits from
SVG.Container
A hyperlink or <a>
tag creates a container that enables a link on all children:
var link = draw.link('http://svgdotjs.github.io/')
var rect = link.rect(100, 100)
The link url can be updated with the to()
method:
link.to('http://apple.com')
Furthermore, the link element has a show()
method to create the xlink:show
attribute:
link.show('replace')
And the target()
method to create the target
attribute:
link.target('_blank')
Elements can also be linked the other way around with the linkTo()
method:
rect.linkTo('http://svgdotjs.github.io/')
Alternatively, a block can be passed instead of a URL for more options on the link element:
rect.linkTo(function(link) {
link.to('http://svgdotjs.github.io/').target('_blank')
})
