我有冲突。我编写了一个简单的脚本,它根据类名过滤 div。它有效,但当我添加第三方脚本时无效。这里的相关行是 .on 函数。第三方代码禁止我的代码运行。 html 代码中的两个目标选项标记。
我尝试删除代码中的“return false”,但没有成功。尝试将我的代码放在顶部......什么也没有。我考虑过使用event.stopPropagation()
。我读到过。这适用于我的情况吗?我该如何整合它?
我想提供一个功能性的jsfiddle,但不幸的是我没有接受过使用帽子网站的训练,因为我更习惯于notepad++和dreamweaver。
这是我的自定义脚本:
jQuery(document).ready(function (e) {
var t = e("#filter-container");
t.imagesLoaded(function () {
t.isotope({
itemSelector: "figure",
filter: "*",
resizable: false,
animationEngine: "jquery"
})
});
$("select").on("change", function () {
var select = $(this);
var selectedOption = select.find("option:selected");
var r = selectedOption.attr("data-filter");
t.isotope({
filter: r
});
return false
});
e(window).resize(function () {
var n = e(window).width();
t.isotope("reLayout")
}).trigger("resize")
});
还有第三方脚本:

这可能是什么?
希望有人能赐教。我目前正在尝试为我病重的弟弟创建一个网站。他一直想要一个音乐网站,所以我想我就为他创建一个。阻止我发布它的唯一因素是这两个脚本之间的冲突。
最佳答案
在评论中聊了很长时间之后......
第三方脚本
是一个插件,用于对下拉列表
(选择
)应用效果。基本上,它将附加元素转换为ul
,并将每个选项
作为li
粘贴在那里。
在您的代码段中,您尝试通过检查选择了哪个选项
来检索选定的值
,但这将不再起作用。
该插件将选定的值
保留在隐藏字段
中。
我会将您的代码更改为如下所示:
$(function () {
var t = $("#filter-container");
t.imagesLoaded(function () {
t.isotope({
itemSelector: "figure",
filter: "*",
resizable: false,
animationEngine: "jquery"
});
});
$(window).on('resize', function () {
var n = $(this).width();
t.isotope("reLayout");
}).trigger("resize");
});
<小时/>
然后在您的页面中查找以下代码并进行更改:
$(function () {
$('#cd-dropdown').dropdown({
gutter : 5,
onOptionSelect: function (opt) {
$("#filter-container").isotope({
filter: opt.data('value')
});
}
});
});
<小时/>
同位素
过滤器适用于您在选择
选项
中设置的类,但随着插件摆脱它并替换使用ul
,此数据现在丢失。
要使其正常工作,您需要稍微更改 select
标记:
<select id="cd-dropdown" class="cd-select">
<option value="*" selected>Pick a Genre</option>
<option value="*">All</option>
<option value=".epic">Epic</option>
<option value=".classic">Classic</option>
<option value=".regional">Regional</option>
<option value=".electronic">Electronic</option>
</select>
