我正在使用keyup
事件处理程序并过滤一些元素。如果没有包含我要搜索的元素,则显示一条消息,提示没有结果,并在有结果时将其删除。除了在这种情况下,这工作得很好:
输入没有任何结果的内容。现在按住“退格键”可以快速删除字符。仍然显示“无结果”。似乎是时间问题,或者也许我不应该使用keyup
。有什么想法吗?
这是一个代码笔:https://codepen.io/west4me/pen/dQZxMZ
我认为这可能是关键:
$("#filter").keyup(function() {
var selectSize = $(this).val();
filter(selectSize);
});
$("#filter").keyup(function() {
var selectSize = $(this).val();
filter(selectSize);
});
function filter(e) {
var numVisible = 0;
var addCard = $('.ourTeamCards');
if (e) {
var regex = new RegExp('\\b\\w*' + e + '\\w*\\b', 'i');
$('.oneStaff').fadeOut(50).filter(function() {
var regExists = regex.test($(this).data('regions'));
if (regExists) {
numVisible += 1;
}
return regExists;
}).fadeIn(50);
if (numVisible == 0) {
$('.noResults').css('display', 'block');
} else {
$('.noResults').css('display', 'none');
}
} else {
$('.oneStaff').fadeIn(50);
}
}

最佳答案
您的else
部分应如下所示:(请参见带有注释的行//这是一个更改)。用表示如果搜索框中没有值,则应隐藏“无结果”。
function filter(e) {
var numVisible = 0;
var addCard = $('.ourTeamCards');
if(e) {
var regex = new RegExp('\\b\\w*' + e + '\\w*\\b', 'i');
$('.oneStaff').fadeOut(50).filter(function () {
var regExists = regex.test($(this).data('regions'));
if(regExists) {
numVisible +=1;
}
return regExists;
}).fadeIn(50);
if (numVisible == 0 && e) {
$('.noResults').css('display', 'block');
}
else {
$('.noResults').css('display', 'none');
}
}
else {
$('.oneStaff').fadeIn(50);
$('.noResults').css('display', 'none'); //THIS IS A CHANGE
}
}
