当我点击tr时,我试图做一个slideToggle,它会扩展一些隐藏的内容。当前,当我这样做时,它会关闭/闪烁,打开和关闭4次。我正在努力做到这一点使得除了div#bounds之外的所有孩子(以及通过关联,它的所有孩子)将获得该onclick属性。
<tr id="attr_expander"><th>Alignment</th><td><input class="attribute" type ="text" disabled="true" />
<div id="bounds">
<label><input type="radio" name="toggle" value = "1"><span></span></label>
<label><input type="radio" name="toggle" value="2"><span></span></label>
<label><input type="radio" name="toggle" value = "4"><span></span></label><br />
<label><input type="radio" name="toggle"value = "16"><span></span></label>
<label><input type="radio" name="toggle"value = "32"><span></span></label>
<label><input type="radio" name="toggle"value = "64"><span></span></label><br />
<label><input type="radio" name="toggle"value = "256"><span></span></label>
<label><input type="radio" name="toggle"value = "512"><span></span></label>
<label><input type="radio" name="toggle"value = "1024"><span></span></label>
</div>
jquery是:
$("#attr_expander").find("*:not(div[id='bounds'])").click(function () {
$("#bounds").slideToggle();
});
让事情变得更好:
#bounds {
margin:4px;
background-color:#EFEFEF;
border-radius:4px;
border:1px solid #D0D0D0;
overflow:auto;
float:left;
}
#bounds label {
float:left;
width:2.25em;
height:3.0em;
border: 1px solid black;
}
#bounds label span {
text-align:center;
padding:3px 0px;
display:block;
width:2.25em;
height:2.75em;
}
#bounds label span:hover
{
background-color:Aqua;
border: 1px solid black;
}
#bounds label input {
position:absolute;
top:-20px;
}
#bounds input:checked + span {
background-color:#404040;
color:#F7F7F7;
}

难道你不能只检查点击事件的目标是什么,只有当节点名是表格单元格时才进行切换吗?
$("#attr_expander").click(function (e) {
if((e.target.nodeName)=="TH" || (e.target.nodeName)=="TD") $("#bounds").slideToggle();
});

您可以绑定到该元素,然后检查#bounds
是否是父项之一。这样,您只绑定一个事件侦听器,而不是每个元素绑定一个。
$("#attr_expander").on('click', function (e) {
var bounds = '#bounds',
$target = $(e.target);
if (!$target.is(bounds) && $target.closest(bounds).length === 0) {
$(bounds).slideToggle();
}
});
