append() is not a function jQuery
提问by Laurent Meyer
I'm quite new to JQuery (I come from Android World) and I do not understand why I'm stuck with Uncaught TypeError: $list.append is not a functionbecause I'm manipulating two jQuery Objects (as far as I know). So here is my code:
我对 JQuery 很陌生（我来自 Android World），我不明白为什么我会被困住，Uncaught TypeError: $list.append is not a function因为我正在操作两个 jQuery 对象（据我所知）。所以这是我的代码：
function transformInList(items, $list){
if ($.isArray(items)){
$.each(items, function(index, value){
var $li = $('<li />');
if (value.name && value.id){
$li.attr('id', value.id);
$li.text(value.name);
$li.attr('class', 'clickableJobs')
$list.append($li);
}
});
}
}
This code is called with this function:
使用此函数调用此代码：
$(document).ready(function(){
var $ul = ('<ul class="side-nav"></ul>');
var jobs = {"jobs":[{"name":"Kellner", "id":"j10"}, {"name":"Fahrer", "id":"j11"}, {"name":"Lehrer", "id":"j12"}]};
transformInList(jobs.jobs, $ul);
$('div#jobColumn').append($ul)
});
My error should be trivial (as is my code ) but I do not get it.
我的错误应该是微不足道的（就像我的代码一样），但我不明白。
Thanks for help :D

Just a typo. You're passing a string, right now.
只是一个错字。你现在正在传递一个字符串。
Change
改变
var $ul = ('<ul class="side-nav"></ul>');
to
到
var $ul = $('<ul class="side-nav"></ul>');
