jQuery: inherit functions to several objects
i made several table-based-widgets (listview-kind-of) which all have the sam开发者_Python百科e characteristics: styling odd/even rows, hover on/off, set color onClick, deleting a row when clicking on trash-icon.
so it's always the same (prototype-)code for each widget. is there a way to have the code only once then simply apply/inherit it to all widgets?
2nd, here's some of the code - could this be optimized?
var me = this;
$("tr",this.table).each(function(i)
{
var tr = $(this);
tr.bind("mouseover",function(){me.hover(tr,true)});
tr.bind("mouseout",function(){me.hover(tr,false)});
tr.bind("click",function(){me.Click(tr)});
});
$("tr").filter(":odd").addClass("odd");
You have 2 options:
First just create a plugin that handles that basic stuff and then create other plugins that do the specialized stuff for that listing.
Second use jQuery.extend to extend one plugin and create a new one.
To optimize this use event delegation ( jquery().live()
)
var me = this;
var id = this.table.attr('id');
$('#'.id)
.live("mouseover",function(){me.hover($(this),true)})
.live("mouseout",function(){me.hover($(this),false)})
.live("click",function(){me.Click($(this)});
$("tr").filter(":odd").addClass("odd");
