这是我的表单
<?php
$sql15 = "select * from reviewed_title";
$query15 = sqlsrv_query( $link, $sql15);
$count = 1;
while( $row = sqlsrv_fetch_array( $query15, SQLSRV_FETCH_ASSOC) ) { ?>
<div class = "title_body">
<div class = "title_top">
<div class="form-group">
<h3><?php
$title_id = $row['id'];
echo $count .". ".$row['title'];
?>
</h3>
</div>
</div>
<?php
$sql16 = "select * from item_reviewed WHERE title_id = $title_id";
$count2=1;
$query16 = sqlsrv_query( $link, $sql16);
$query17 = sqlsrv_query($link, $sql16, array(), array( "Scrollable" => SQLSRV_CURSOR_KEYSET ));
$row_num = sqlsrv_num_rows($query17);
//$row_num = 5;
while( $row2 = sqlsrv_fetch_array( $query16, SQLSRV_FETCH_ASSOC) ) { ?>
<div class = "title_bottom"
<?php if($row_num != $count2){?> style="border-bottom: 1px solid #000000;" <?php }?> >
<div class="form-group">
<input type="hidden" name="item_reviewed_id" value="<?php echo $row2['id'];?>" class="item_reviewed_id">
<div class = "title_bottom_left">
<h6> <?php echo $count.".".$count2 .". ".$row2['items'];
?></h6>
</div>
<div class= "title_bottom_center">
<label class="col-sm-2 label2" for="email">Y,N,N/A:</label>
<!--<select name="action" class="select <select_<?php echo $row2['id'];?>" id="select_<?php echo $count."".$count2;?>">-->
<select name="action" class="select" >
<option value="">Select</option>
<option value="yes">Yes</option>
</select>
</div>
<div class ="title_bottom_right">
<label class="col-sm-2 label3" for="email">Comment:</label>
<!--<textarea name="comment" class="form-control comment commentttt comment_<?php echo $row2['id'];?>>" <id="comment_<?php echo $count."".$count2;?>" placeholder="Comment"></textarea>-->
<textarea name="comment" class="form-control comment commentttt" placeholder="Comment"></textarea>
</div>
</div>
</div>
<?php $count2++;}?>
</div>
<?php $count++; }?>
这里我得到33个输入字段，33个选择字段和33个隐藏字段。从表item_reviews这里我得到33行。我的jQuery代码是…
var ittem_id = new Array();
var j = 1;
$(".item_reviewed_id" ).each(function( i ) {
ittem_id[j] = $(this).val();
j++;
});
alert(j);
这里我得到1552个值。如何在jQuery中获得33个值?
如果您有1552项，并且该循环只输出33行，那么您必须在页面中使用类.item_reviewed_id的其他元素。使用两个类来确保你选择了正确的元素。JQuery map是映射元素值的一种非常简单的方法
<input type="hidden" name="item_reviewed_id" value="<?php echo $row2['id'];?>" class="item_reviewed_id thisclass">
var ittem_id = $('.item_reviewed_id.thisclass').map(function(){
return $(this).val();
});
console.log(ittem_id); //this will be an array with your values!
