表单serializeArray不工作

Question

<form name = "indexSummaryForm">
<table class = "rtmindex">                                                  
    <tr>
        <td class = "rtmcolumntwo">
            <select id = "intraDayFXRateType" name = "intraDayFXRateType" class = "rtmindexselect">
                <option id = "4" selected>SPOT</option>
            </select>
        </td>
        <td class = "rtmcolumnfour">
            <input id = "preMarketOpenInterval" name = "preMarketOpenInterval" class = "rtmindexcell" type = "text" value = "0" />
        </td>
        <td class = "rtmcolumnsix">
            <select id = "intraDayFXRateBehaviour" name = "intraDayFXRateBehaviour" class = "rtmindexselect">
                <option id = "1" selected>Spot Rate</option>
                <option id = "2">Prev. Day WMSpot</option>
            </select>
        </td>
    </tr>

</table>
</form>

当我尝试提交表单时，警告( "test：“+ $('#indexSummaryForm').serializeArray())；返回null。请检查并告知代码中有什么问题？

Answer 1

这段代码

$('#indexSummaryForm').serializeArray())

是使用没有ID属性的ID="indexSummaryForm"，请求对象。

Answer 2

您没有带有id indexSummaryForm的窗体。

 $('[name=indexSummaryForm]') // Should work

否则，可以将id添加到窗体并使用id selector。
