javascript - How are parameters passed to knockout functions? -


for binding : 

<a data-bind='click: $root.thisvalue '>

the corresponding knockout function takes 'link' parameter : 

this.thisvalue = function(link) {

how 'link' parameter set ? does'nt seem set within data binding ?

its not element, data context associated element

http://jsfiddle.net/fpyks/

viewmodel = function() {     this.data = "data";         }  viewmodel.prototype = {     handle: function(item) {         console.log(item.data);     } };

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
