我正在使用Javascript创建一个搜索+下拉列表,并且出于某种原因,单击Tree
元素时没有触发像它应该的链接。回到我在codepen上找到的样本后,它有同样的问题:search-box-with-suggestions
我使用了一些过滤逻辑和<li>
将列表项添加为链接。
我非常感谢任何帮助!我也试过使用jQuery.append()
事件无济于事。
以下是我的一些代码:
onclick()
&#13;
// Search Bar Filter Logic
function searchPlayers() {
var input, filter, ul, li, a, i;
input = document.getElementById("searchBarInput");
filter = input.value.toUpperCase();
div = document.getElementById("dropdownItems");
li = div.getElementsByTagName("li");
// remove all current items
for (i = li.length - 1; i > -1; i--) {
div.removeChild(li[i]);
}
// check for min length
if (filter.length < 3) {
$('#dropdownItems').append("<li><a>Please input at least 3 characters.</a></li>");
} else {
// Here I add filtered items to the drop dwon
$('#dropdownItems').append("<li><a href='playerPage.html?playerID=" + "playerID" + "'>" + "Player Name" + " - " + "Player Position" + "</a></li>");
}
}
// Search Bar focus lost
$(document).on("focusout", "#searchBarInput input", function() {
var div = document.getElementById("dropdownItems");
var li = div.getElementsByTagName("li");
// remove all current items
for (i = li.length - 1; i > -1; i--) {
div.removeChild(li[i]);
}
});

答案 0 :(得分:2)
仅当输入字段具有:focus
时(即,当用户在输入字段内单击时),该链接才可见。您需要调整显示结果列表的css选择器以在结果列表中包含:hover
(因此在填充列表后,用户将鼠标移到列表上,当用户单击该列表时,列表仍然可见输入并输入结果):
.search input:focus + .results,
.search .results:hover { display: block }
// Search Bar Filter Logic
function searchPlayers() {
var input, filter, ul, li, a, i;
input = document.getElementById("searchBarInput");
filter = input.value.toUpperCase();
div = document.getElementById("dropdownItems");
li = div.getElementsByTagName("li");
// remove all current items
for (i = li.length - 1; i > -1; i--) {
div.removeChild(li[i]);
}
// check for min length
if (filter.length < 3) {
$('#dropdownItems').append("<li><a>Please input at least 3 characters.</a></li>");
} else {
// Here I add filtered items to the drop dwon
$('#dropdownItems').append("<li><a href='playerPage.html?playerID=" + "playerID" + "'>" + "Player Name" + " - " + "Player Position" + "</a></li>");
}
}
// Search Bar focus lost
$(document).on("focusout", "#searchBarInput input", function() {
var div = document.getElementById("dropdownItems");
var li = div.getElementsByTagName("li");
// remove all current items
for (i = li.length - 1; i > -1; i--) {
div.removeChild(li[i]);
}
});
