如果我的问题重复,我道歉。我研究了所有相同的问题并做了以下事情: 1.删除所有禁用的输入字段。 2.检查是否有重复的id。没有id重复。 3.每个表单字段都有一个名称。 但是下面的代码返回空字符串:
$('#answer_sheet_btn').click(function(e){
e.preventDefault();
console.log( $( this ).serializeArray() );
});
这是我的表格:
<form method="post" action="/wordpress/wp-admin/admin.php?page=active-exam&exam_id=1" id="question_paper">
<p></p><table class="bix-tbl-container" style="height: 40px" border="0" width="533" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td class="bix-td-qtxt" valign="top">If 60 J of energy are available for every 15 C of charge, what is the voltage?</td>
</tr>
</tbody>
</table><p></p>
<input name="opt1[]" type="checkbox" value="1">60 V <input name="opt1[]" type="checkbox" value="2">4 V <input name="opt1[]" type="checkbox" value="3">15 V <input name="opt1[]" type="checkbox" value="4">.25 V <hr>
<p>Which resistive component is designed to be temperature sensitive?</p>
<input name="opt2[]" type="checkbox" value="1">Rheostat <input name="opt2[]" type="checkbox" value="2">Thermistor <input name="opt2[]" type="checkbox" value="3">Potentiometer <input name="opt2[]" type="checkbox" value="4">Photoconductive cell <hr>
<input type="hidden" name="q_ids" value="1,2">
<p class="submit">
<input type="submit" name="answer_sheet" id="answer_sheet_btn" class="button-primary" value="submit">
</p>
</form>
这杀了我的一天。我想我在做一些愚蠢的错误。请指出。
N.B:我尝试删除隐藏的字段
<input type="hidden" name="q_ids" value="1,2">

.serializeArray()方法创建一个JavaScript对象数组,可以编码为JSON字符串。它运行在jQuery表单和/或表单控件集合上。
您应该处理表单提交操作,然后序列化表单:
$('#question_paper').submit(function(e){
e.preventDefault();
console.log( $(this).serializeArray() );
});
$('#question_paper').submit(function(e){
e.preventDefault();
console.log( $(this).serializeArray() );
});
