我目前正在使用Isotope过滤出版物列表,但希望能够将标准的,记录在案的链接过滤器方法与select元素结合起来,因为我的第二个过滤器列表很长。
我正在努力解决的问题是处理两种不同类型的元素,将选择的值组合到一个选项数组中。我可以使过滤器彼此独立工作(下面的代码),但它们需要协同工作。如何将两个不同的操作(单击或更改)和两个属性(class =或value =)组合到一个选项数组中以传递给isotop过滤器?
var $container = $('#library');
// select ccskills publications by default
$container.isotope({ filter: '.ccskills' });
var $optionSets = $('#library-options .option-set'),
$optionLinks = $optionSets.find('a');
$optionLinks.click(function(){
var $this = $(this);
// don't proceed if already selected
if ( $this.hasClass('selected') ) {
return false;
}
var $optionSet = $this.parents('.option-set');
$optionSet.find('.selected').removeClass('selected');
$this.addClass('selected');
// make option object dynamically, i.e. { filter: '.my-filter-class' }
var options = {},
key = $optionSet.attr('data-option-key'),
value = $this.attr('data-option-value');
// parse 'false' as false boolean
value = value === 'false' ? false : value;
options[ key ] = value;
$container.isotope( options );
return false;
});
// using the 'chozen' plugin to style my select element
$(".chzn-select").chosen().change(
function() {
var industry = $("option:selected", this).val();
$container.isotope({filter: industry});
}
);

您需要一个多维数组,每个过滤器类型都有一个数组维度。我之前已经完成了这个,并且有一个现场演示示例here!
见here!对于js。
在我的js文件中,你会对名为getComboFilters(filters)的结束函数感兴趣
function getComboFilter( filters ) {
var i = 0;
var comboFilters = [];
var message = [];
for ( var prop in filters ) {
message.push( filters[ prop ].join(' ') );
var filterGroup = filters[ prop ];
// skip to next filter group if it doesn't have any values
if ( !filterGroup.length ) {
continue;
}
if ( i === 0 ) {
// copy to new array
comboFilters = filterGroup.slice(0);
}
else {
var filterSelectors = [];
// copy to fresh array
var groupCombo = comboFilters.slice(0); // [ A, B ]
// merge filter Groups
for (var k=0, len3 = filterGroup.length; k < len3; k++) {
for (var j=0, len2 = groupCombo.length; j < len2; j++) {
filterSelectors.push( groupCombo[j] + filterGroup[k] ); // [ 1, 2 ]
}
}
// apply filter selectors to combo filters for next group
comboFilters = filterSelectors;
}
i++;
}
comboFilters.sort();
var comboFilter = comboFilters.join(', ');
return comboFilter;
}
这个函数处理各种过滤器阵列的所有推送,拼接和排序,但要使用它你需要将它添加到你的过滤器例程......好吧我说常规但它的例程真的因为你似乎打电话过滤方法2分开:
$container.isotope({ filter: '.ccskills' });
以后:
$container.isotope({filter: .industry});
如果要一起过滤类型,所有过滤器类型都必须相互了解,这意味着它们必须位于相同的javascript机箱内,并且过滤器方法只需要调用一次哪个时候它会针对你所有的过滤器类型条件进行测试。
使用getComboFilter(filters)函数调用组合过滤器方法,如下所示:
var $container = $('#library');
var filters = {};
var comboFilter = getComboFilter( filters );
$container.isotope({ filter: comboFilter });
最后,完全集成到您的文件中可能是这样的:
var $container = $('#library');
var filters = {};
var comboFilter = getComboFilter( filters );
$container.isotope({ filter: comboFilter });
// This next part targets all the possible filter items
// i.e. '.option-set a' just like your example
$('.option-set a').click(function(){
// exit directly if filter already disabled
if ($(this).hasClass('disabled') ){
return false;
}
var $this = $(this);
var $optionSet = $(this).parents('.option-set');
var group = $optionSet.attr('data-filter-group');
// store filter value in object
var filterGroup = filters[ group ];
if ( !filterGroup ) {
filterGroup = filters[ group ] = [];
}
var comboFilter = getComboFilter( filters );
$container.isotope({ filter: comboFilter });
});
function getComboFilter( filters ) {
var i = 0;
var comboFilters = [];
var message = [];
for ( var prop in filters ) {
message.push( filters[ prop ].join(' ') );
var filterGroup = filters[ prop ];
// skip to next filter group if it doesn't have any values
if ( !filterGroup.length ) {
continue;
}
if ( i === 0 ) {
// copy to new array
comboFilters = filterGroup.slice(0);
}
else {
var filterSelectors = [];
// copy to fresh array
var groupCombo = comboFilters.slice(0); // [ A, B ]
// merge filter Groups
for (var k=0, len3 = filterGroup.length; k < len3; k++) {
for (var j=0, len2 = groupCombo.length; j < len2; j++) {
filterSelectors.push( groupCombo[j] + filterGroup[k] ); // [ 1, 2 ]
}
}
// apply filter selectors to combo filters for next group
comboFilters = filterSelectors;
}
i++;
}
comboFilters.sort();
var comboFilter = comboFilters.join(', ');
return comboFilter;
}
希望这有助于某人!这个演示很漂亮。
