jQuery 过滤每个不为空的字符串
jQuery filter for each string that's not null
我如何为每个不为空的字符串应用 jQuery 过滤器?
基本上,我有以下代码,并希望它适用于预先设置的任意数量的 "selectors"。
可用的选择器列表将在一个数组中。
if (typeselector === '' && colorselector === '') {
$('.product').filter(selector).show();
} else if (typeselector === '') {
$('.product').filter(selector).filter(colorselector).show();
} else if (colorselector === '') {
$('.product').filter(selector).filter(typeselector).show();
} else {
$('.product').filter(selector).filter(typeselector).filter(colorselector).show();
}
感谢任何suggestions/help!
为了简化,您可以使用链接:
var products = $('.product').filter(selector);
if (typeselector !== '') {
products = products.filter(typeselector);
}
if (colorselector !== '') {
products = products.filter(colorselector);
}
products.show();
甚至是这样的:
var products = $('.product').filter(selector);
var selectors = [typeselector, colorselector];
selectors.each(function(selector) {
if (selector !== '') {
products = products.filter(selector);
}
});
products.show();
