javascript - Access Child Element's DOM Node in React -
i working react & svg.
in order centre viewbox on child <g>
, need 'bbox' value calling getbbox()
api function on child <g>
element. code looks this:
// <svg> element const svgparent = react.createclass({ componentdidmount : function(){ let elebbox = reactdom.finddomnode( this.refs.gele ).getbbox(); ... // child <g> element const templateparent = react.createclass({ render : function(){ return( <g ref = "gele"> ...
the above line let elebbox = reactdom.finddomnode( this.refs.gele )
returns error: typeerror: _reactdom2.default.finddomnode(...) null
and indeed, this.refs
inside 'svg' element empty obj. how access child <g>
element, can access dom node?
thanks,
if put ref on child can in parent so, no need dom node:
const svgparent = react.createclass({ componentdidmount : function(){ let elebbox = this.refs.gele ...
