我是jQuery的新手,需要帮助。我得到了这个代码,工作正常:
<script>
(function ($) {
// custom css expression for a case-insensitive contains()
jQuery.expr[':'].Contains = function(a,i,m){
return (a.textContent || a.innerText || "").toUpperCase().indexOf(m[3].toUpperCase())>=0;
};
function listFilter(header, list) { // header is any element, list is an unordered list
// create and add the filter form to the header
var form = $("<form>").attr({"class":"filterform","action":"#"}),
input = $("<input>").attr({"class":"filterinput","type":"text"});
$(form).append(input).appendTo(header);
$(input).change( function () {
var filter = $(this).val();
if(filter) {
// this finds all links in a list that contain the input,
// and hide the ones not containing the input while showing the ones that do
$(list).find("a:not(:Contains(" + filter + "))").parent().slideUp();
$(list).find.hasClass(Lot) + ("a:Contains(" + filter + ")").parent().slideDown();
} else {
$(list).find("li").show();
}
return false;
}).keyup( function () {
// fire the above change event after every letter
$(this).change();
});
}
//ondomready
$(function () {
listFilter($("#header"), $("#list"));
});
}(jQuery));
</script>

我只想过滤p class="Lot"
中的数字,但要显示整个li
。
我尝试使用.hasClass
,但它没有用。谢谢你的帮助。
答案 0 :(得分:0)
$(list).find.hasClass(Lot)
无法正常工作。没有定义Lot变量; - )
尝试
$(list).find.hasClass("Lot")
使用jQuery按类选择元素的最简单方法是
$('.Lot',list);
你可以把它结合起来:
$(".Lot:Contains(" + filter + ")", list).parent().slideDown();
