jquery.lyhucSelect.js

復(fù)制代碼代碼如下:

 
(function($) { 
$.fn.lyhucSelect = function(options) { 
var element = this; 
var elementid = "#" + element[0].id; 
var defaults = { 
dataSource:{}, 
subSelect:'#subcategory',

value:'0', 
parentid:0 
}; 
var options = $.extend(defaults, options); 
var defaultoption = new Option(); 
var defaultsuboption = new Option(); 
(function init(){ 
defaultoption.text=options.option.text; 
defaultoption.value=options.option.value; 
$(elementid).append(defaultoption); 
defaultsuboption.text=options.option.text; 
defaultsuboption.value=options.option.value; 
$(options.subSelect).append(defaultsuboption); 
$(options.dataSource).each(function(i){ 
var id=options.dataSource[i][0]; 
var mc=options.dataSource[i][1]; 
if(options.parentid==options.dataSource[i][2]) 
{ 
var newoption = new Option(); 
newoption.value=id; 
newoption.text=mc; 
$(elementid).append(newoption); 
} 
}); 
})(); 
return this.each(function(){ 
$(this).bind("change",function(e){ 
var currentVal=$(this).val(); 
var tmpDepth=0; 
$(options.subSelect).empty(); 
$(options.dataSource).each(function(i){ 
var id=options.dataSource[i][0]; 
var mc=options.dataSource[i][1]; 
if(currentVal==options.dataSource[i][2]) 
{ 
var newoption = new Option(); 
newoption.value=id; 
newoption.text=mc; 
$(options.subSelect).append(newoption); 
tmpDepth++; 
} 
}); 
if(tmpDepth==0) 
{ 
var parentoption = new Option(); 
parentoption.value=$(elementid).val(); 
parentoption.text=$(elementid).find('option:selected').text(); 
$(options.subSelect).append(parentoption); 
} 
}); 
}); 
}; 
})(jQuery);
