我在 html 表中有一个表单。
我正在通过 jquery 将输入字段动态添加到表单中。当我在提交表单时使用 var dump 时，$_POST 数组没有添加的字段。为什么会这样？
这是我的 js 的样子：
$('#add-more-del-areas').live('click',function(e){
var del_area_count = $('[name=number_of_delivery_areas]').val();
var new_count = (parseInt(del_area_count)+1);
var tr_html = '<tr>'+
'<td style="padding:10px 0px 0px 10px;"><strong>Delivery Area '+new_count+'</strong></td>'+
'<td>'+
'<input name="d_area'+new_count+'" type="text" size="50" value=""/>'+
'<div class="area-display-container" id="test'+new_count+'-display"></div>'+
'<div>'+
'<input class="auto-suggest-input" type="text" autocomplete="off" id="test'+new_count+'"/>'+
'<div class="test-content" id="test'+new_count+'-content"></div>'+
'</div>'+
'</td>'+
'</tr>'+
'<tr id="del_area-'+new_count+'" bgcolor="#FF9933">'+
'<td style="padding:10px 0px 0px 10px;"><strong>Dilivery charges for area '+new_count+'</strong></td>'+
'<td><input name="m_order'+new_count+'" type="text" size="50" value="0"></td>'+
'</tr>';
//$('#del_area-'+del_area_count).after(tr_html);
$(tr_html).insertAfter('#del_area-'+del_area_count);
big_cms.auto_suggest_({id: 'test'+new_count,input_field: 'd_area'+new_count});
$('[name=number_of_delivery_areas]').val(new_count);
e.preventDefault();
});
虽然 html 很可悲而且仍然太长，但它是：
