通过ajax获取单选按钮值

我想获取单选按钮值并将其通过AJAX发送到PHP。

我的AJAX正在运行,但当前正在0每行中插入一个,因此它不会从单选按钮中获取值。任何帮助,将不胜感激。

$("#save_privacy").submit(function() {

var message_pri = $("#message_pri").val();

var follow_pri = $("#follow_pri").val();

var post_pri = $("#post_pri").val();

var check7 = $("#check7").val();

var s = {

"message_pri": message_pri,

"follow_pri": follow_pri,

"post_pri": post_pri,

"check": check7

}

$.ajax({

url: 'edit_check.php',

type: 'POST',

data: s,

beforeSend: function() {

$(".privacy_info").html("<img src=\"style/img/ajax/load2.gif\" alt=\"Loading ....\" />");

},

success: function(data) {

$(".privacy_info").html(data);

}

});

return false;

});

<form id="save_privacy">

<table align="center" width="70%" cellpadding="0" cellspacing="0" border="0">

<tr>

<td style="padding: 5px;">

<b>Message Buttun: </b>

</td>

<td style="padding: 5px;">

<input type="radio" id="message_pri" name="message_pri" value="1" /> ON

<input type="radio" id="message_pri" name="message_pri" value="2" /> OFF

<input type="radio" id="message_pri" name="message_pri" value="3" /> FOLLOWERS

</td>

</tr>

<tr>

<td style="padding: 5px;">

<b>Follow Buttun: </b>

</td>

<td style="padding: 5px;">

<input type="radio" id="follow_pri" name="follow_pri" value="1" /> ON

<input type="radio" id="follow_pri" name="follow_pri" value="2" /> OFF

</td>

</tr>

<tr>

<td style="padding: 5px;">

<b>Who Can Post On Your Profile: </b>

</td>

<td style="padding: 5px;">

<input type="radio" id="post_pri" name="post_pri" value="1" /> Evry one

<input type="radio" id="post_pri" name="post_pri" value="2" /> Followers

</td>

</tr>

<tr>

<td colspan="2" style="padding: 5px;">

<input type="hidden" id="check7" value="save_privacy" name="check7" />

<input class="small color blue button" type="submit" value="Save" />

</td>

</tr>

</table>

<div class="privacy_info"></div>

</form>

回答:

首先,您有很多重复的id属性,这是不正确的。请改用类,然后使用:checked选择器来获取所选无线电的特定实例。

试试这个:

<input type="radio" class="message_pri" name="message_pri" value="1" /> ON  

<input type="radio" class="message_pri" name="message_pri" value="2" /> OFF

<input type="radio" class="message_pri" name="message_pri" value="3" /> FOLLOWERS

var message_pri = $(".message_pri:checked").val();

以此类推,作为您的其他radio输入。
