我正在尝试提取 MultiLevelPushMenu 插件中当前元素的根路径。
https://github.com/adgsm/multi-level-push-menu
所有者给出了将根级路径提取到文档中的方法
/**
* Find path to root of selected menu level object
* Provides chain collection of menu level objects (root menu level object to given menu level object), or false in case of error
*/
$('#menu').multilevelpushmenu('pathtoroot', $menuLevelObject);
我已尝试按照指南使用相同的方法，但我得到的是 HTMLLiobject，但无法深入挖掘路径。
我需要从这个集合中获取字符串格式的路径，有什么帮助吗？
这是我的代码..
$(document).ready(function(){
// HTML markup implementation, overlap mode
$( '#menu' ).multilevelpushmenu({
containersToPush: [$( '#pushobj' )],
menuWidth: '25%',
menuHeight: '100%',
onItemClick: function() {
// First argument is original event object
var event = arguments[0],
// Second argument is menu level object containing clicked item (
element)
$menuLevelHolder = arguments[1],
// Third argument is clicked item (
element)
$item = arguments[2],
// Fourth argument is instance settings/options object
options = arguments[3];
// You can do some cool stuff here before
// redirecting to href location
// like logging the event or even
// adding some parameters to href, etc...
var path = $('#menu').multilevelpushmenu('pathtoroot', $item);
alert(path);
}
});
});
最佳答案
下面更新的例子应该给你:
/All Categories/Devices/Mobile Phones/Super Smart Phone
单击最后一个元素 - 而不是您当前正在获取的对象字符串...
$(document).ready(function(){
// HTML markup implementation, overlap mode
$( '#menu' ).multilevelpushmenu({
containersToPush: [$( '#pushobj' )],
menuWidth: '25%',
menuHeight: '100%',
onItemClick: function() {
// First argument is original event object
var event = arguments[0],
// Second argument is menu level object containing clicked item (element)
$menuLevelHolder = arguments[1],
// Third argument is clicked item (element)
$item = arguments[2],
// Fourth argument is instance settings/options object
options = arguments[3];
// You can do some cool stuff here before
// redirecting to href location
// like logging the event or even
// adding some parameters to href, etc...
var path = $('#menu').multilevelpushmenu('pathtoroot', $item);
//console.log(path);
//console.log('element0: ', path[0]);
//console.log('element1: ', path[1]);
//console.log('----------------------------------');
//console.log('element0 inner html: ', $(path[0]).html());
var s = ''; // string to hold path
for(var i = 0, length = path.length; i < length; i++)
{
var html = $(path[i]).find('h2').html();
if(html) s += '/' + html.split('</i>')[1];
}
s += '/' + $item.find('a').text();
console.log(s);
}
});
