我在AJAX调用中使用<ul>
动态插入.html()
和列表项。我想计算动态插入的<ul>
中的列表项数。
代码:
<div id='layout'>
<a href='javascript:void(0);' class='close'><img src='images/close.png' width='17' /></a>
<div id='buslayout'></div>
<div id='boarding'>
<select name='boarding' id='boarding'>
<option value=''>Boarding points</option>
</select>
</div>
<div class='seats'><p>Selected seats: <span id='totalseats'></span></p></div>
<div class='seats'><p>Total: <span id='total'></span></p></div>
<div class='seats'><p><input type='submit' value='Continue booking' /></p></div>
<div class='clear'></div>
</div>
jQuery的:
$('#buslayout').html(data);
$('ul li').each(function(){
price += parseInt($(this).attr('price'));
console.log($(this).attr('price'));
});
动态生成的html。
<ul>
<li price='100'>Bus</li>
<li price='200'>Bus</li>
<li price='250'>Bus</li>
<li price='450'>Bus</li>
</ul>

统计列表项?
$('#buslayout').html(data).find('li').length
或者,如果你想在循环时这样做:
var liCount = 0;
$('ul li').each(function(){
price += parseInt($(this).attr('price'));
console.log($(this).attr('price'));
liCount ++;
});

您是否已将总座位定义为jQuery变量?
$totalseats = jQuery('.seats');
totalseats.each(function() { ...
**Edit**
Then load the file with $.ajax() and iterate over the returned data
$.ajax({
url: 'your file',
success: function(data){
$.each(data, function(){
// your func
});
}
});
