目前有一个问题，我想要做一个简单的jQuery追加将div移动到另一个div。在这种情况下，当我在搜索框中键入时，建议的结果应显示在下方。然而，由于我自己改变了一些代码，它不再出现在左边，所以我做了一个简单的jQuery追加，让我的生活更轻松。
问题在于，当我进行简单搜索并且搜索框下方出现结果框时，我使用控制台来执行以下代码行：
$('#QuickSearch').appendTo($('#searchheader'));
在控制台中一切正常。但是当我把它放在搜索的javascript文件中时，它不执行那行代码。下面是与搜索相关联的jQuery：
var QuickSearch = {
minimum_length: 3,
search_delay: 125,
cache: new Object(),
init: function()
{
$('#search_query').bind("keydown", QuickSearch.on_keydown);
$('#search_query').bind("keyup", QuickSearch.on_keyup);
$('#search_query').bind("change", QuickSearch.on_change);
$('#search_query').blur(QuickSearch.on_blur);
$('#search_query').attr('autocomplete', 'off');
var scripts = document.getElementsByTagName('SCRIPT');
for(var i = 0; i < scripts.length; i++)
{
s = scripts[i];
if(s.src && s.src.indexOf('quicksearch.js') > -1)
{
QuickSearch.path = s.src.replace(/quicksearch\.js$/, '../');
break;
}
}
},
on_blur: function(event)
{
if(!QuickSearch.item_selected && !QuickSearch.over_all)
{
QuickSearch.hide_popup();
}
},
on_keydown: function(event)
{
if(event.keyCode == 13 && !event.altKey)
{
if(QuickSearch.selected)
{
try {
event.preventDefault();
event.stopPropagation();
} catch(e) { }
window.location = QuickSearch.selected.url;
return false;
}
else
{
QuickSearch.hide_popup();
}
}
else if(event.keyCode == 27)
{
if(document.getElementById('QuickSearch'))
{
try {
event.preventDefault();
event.stopPropagation();
} catch(e) { }
}
QuickSearch.hide_popup();
}
},
on_keyup: function(event)
{
if(QuickSearch.timeout)
{
clearTimeout(QuickSearch.timeout);
}
// Down key was pressed
if(event.keyCode == 40 && QuickSearch.results)
{
if(QuickSearch.selected && QuickSearch.results.length >= QuickSearch.selected.index+1)
{
QuickSearch.highlight_item(QuickSearch.selected.index+1, true);
}
if(!QuickSearch.selected && QuickSearch.results.length > 0)
{
QuickSearch.highlight_item(0, true);
}
try {
event.preventDefault();
event.stopPropagation();
} catch(e) { }
return false;
}
