Question

我关注ICanHaz表单模板：

<script id="outcomeFormTemplate" type="text/html">
    <form id="xyz" class="form-horizontal well" data-async data-target="#outcomeFormDialog" method="POST">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal">×</button>
            <h3 id="myModalLabel">Add outcome</h3>
        </div>
        <div class="modal-body">
            <fieldset>
                <label>Amount</label>
                <div class="input-append">
                    <input type="text" placeholder="00.01" />
                    <span class="add-on">{{ currency }}</span>
                </div>
                {{>UserSelectTemplate}}
                {{>CategorySelectTemplate}}
                <label>Comment</label>
                <input type="text" placeholder="Comment here..." />
            </fieldset>
        </div>
        <div class="modal-footer">
            <button class="btn" data-dismiss="modal">Close</button>
            <button type="submit" class="btn btn-primary">Save outcome</button>
        </div>
    </form>
</script>

呈现如下：

<form id="xyz" class="form-horizontal well" data-async="" data-target="#outcomeFormDialog" method="POST">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal">×</button>
            <h3 id="myModalLabel">Add outcome</h3>
        </div>
        <div class="modal-body">

问题是.serialize()返回空字符串。这是为什么？我的html结构出了什么问题？

$("#xyz").serialize()
""

Answer 1

您需要设置表单字段的名称。否则它不知道如何命名字段。我没有尝试过，所以我不知道通常会发生什么，但这是有道理的。

例如：

<select name="user">

Answer 2

serialize() 查找输入的名称属性，因此请在其输入的输入中使用name属性。

<label>Amount</label>
<div class="input-append">
    <input type="text" name='amt' placeholder="0.01">
    <span class="add-on">zł</span>
</div>

如上所述在其输入的输入中使用name属性。

表单序列化不起作用
