点击此元素时我试图隐藏一些元素（Google Chart上的categoryfilter的选项值）
<div class="goog-menuitem goog-option" role="menuitemradio" aria-checked="false" style="user-select: none;" id=":4">Middle East</div>
和
<div class="goog-menuitem goog-option" role="menuitemradio" aria-checked="false" style="user-select: none;" id=":0" aria-hidden="false"><div class="goog-menuitem-content" style="user-select: none;"><div class="goog-menuitem-checkbox" style="user-select: none;"></div>Africa</div></div>
所以我写了这段代码
google.visualization.events.addListener(namePicker, 'statechange', hidediv);
function hidediv() {
$("#:0.goog-menuitem.goog-option").click(function() {
document.getElementById('2000').hide();
document.getElementById('2010').hide();
document.getElementById('2017').hide();
});
$("#:4.goog-menuitem.goog-option").click(function() {
document.getElementById('2000').hide();
document.getElementById('2010').hide();
document.getElementById('2017').hide();
});
}
但我收到了错误
语法错误，无法识别的表达式：＃：0.goog-menuitem.goog-option

根据How do I select an element by an ID that has characters used in CSS notation?你需要写：
$("#\\:0.goog-menuitem.goog-option")
