我正在尝试在MultiLevelPushMenu插件中提取当前元素的根路径.
https://github.com/adgsm/multi-level-push-menu 所有者已经使用Method将根级别路径提取到文档中 /**
* 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);
我已经尝试按照指南使用相同但我得到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,任何帮助？ 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);
}
});
});
here is what I’m getting 解决方法
以下更新的示例应该为您提供：
/All Categories/Devices/Mobile Phones/Super Smart Phone 单击最后一个元素 – 而不是您当前获得的对象字符串… $(document).ready(function(){
// HTML markup implementation,overlap mode
$( '#menu' ).multilevelpushmenu({
containersToPush: [$( '#pushobj' )],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);
}
});
});
