如何检查节中的(required)输入字段的空值,然后使用jQuery在事件上为它们添加一个类？到目前为止,我尝试过:

jQuery("#sender_container input.required").val("").addClass("error");

但这似乎是设定价值,而不是检查它.有任何想法吗？

出于某种原因,使用文本阴影时,Firefox和Chrome会以不同方式呈现行高.

CSS:

#tracker {
    width:200px;
    color:#999;
    font:normal 12px Verdana,sans-serif;/* Swapped out Arial with Verdana */
}

#tracker ol {
    float: right;
    margin: 0;
    padding: 0;
    white-space: nowrap;
    list-style: none;
}

#tracker li {
    float: left;
    margin: 0 0 0 6px;
    padding: 0;
    height: 13px;
    width: 13px;
    color: #666;
    background-color: #ccc;
    border: 1px solid #c0c0c0;
    border-radius: 9px;
    -moz-border-radius: 9px;
    -webkit-border-radius: 9px;
    text-align: center;
    line-height: 13px;
    font-size: 9px;
    text-shadow: 1px 1px 1px #fff;
    overflow: hidden;
}

#tracker li.current {
    color: #fff;
    text-shadow: …

是否有任何方法可以将click事件附加到多个元素,然后将所有子元素都添加到该元素中,除了THIS(单击一个)的子元素以运行函数？

这是一个可怕的解释,但我正在寻找这样的事情:

$(".block_header").click(function(){
    $(".block_header span:not(this span)").toggleClass("collapse expand");
    $(".container:not(this+div.container)").slideToggle();
});

这是一个示例HTML:

<h3 id="sender_header" class="block_header"><span>Sender</span></h3>
<div id="sender_container" class="container">
    <p>Show or hide this, based on which H3 is clicked.</p>
</div>
<h3 id="receiver_header" class="block_header"><span>Receiver</span></h3>
<div id="receiver_container" class="container">
    <p>Show or hide this, based on which H3 is clicked.</p>
</div>
<h3 id="delivery_header" class="block_header"><span>Delivery</span></h3>
<div id="delivery_container" class="container">
    <p>Show or hide this, based on which H3 is clicked.</p>
</div>
<h3 id="items_header" class="block_header"><span>Items</span></h3>
<div id="items_container" class="container">
    <p>Show or hide this, based on which H3 is clicked.</p>
</div>
.... etc, …
