我正在尝试使用jquery构建一个购物车,我正在努力弄清楚如何让它全部工作。
我有个地方可以在我的网站上购买广告空间。将有一个包含5列的表格(邮政编码列(输入),服务栏(选择框),广告尺寸(选择框),广告价格(输入只读)和用于添加或删除行的选项列。我让一切都运转正确,直到我想为大型或小型广告添加选项,并根据广告尺寸收取不同的价格。
<table style='width: 100%;' id='adsTable'>
<tr class='addedRow'>
<td>Zip</td>
<td>Service</td>
<td>Ad Size</td>
<td>Price</td>
<td>Options</td>
</tr>
<tr>
<td><input type='text' maxlength='5' class='zip' /></td>
<td>
<select name='serviceType' class='serviceType rounded'>
<option value="">Choose One...</option>
<option>Plumbing</option>
<option>Roofing</option>
<option>HVAC</option>
<option>Appliance Repair</option>
<option>Flooring</option>
<option>Electrical</option>
<option>Doors/Windows</option>
<option>Siding</option>
<option>Other</option>
</select>
</td>
<td>
<select name='' class='ad_size'>
<option value='4.99' class='ad_lg'>Large</option>
<option value='1.99' class='ad_sm'>Small</option>
</select>
</td>
<td>
<div class="input-prepend">
<span class="add-on"><i class="icon-usd"></i></span>
<input class='addPrice' value='4.99' type='text' readonly='readonly' />
</div>
</td>
<td class='options'>
</td>
</tr>
</table>
我将我的jquery剥离并重新启动了几次以尝试全部解决,但在选择广告尺寸后仍然坚持如何添加所有输入。在我来到这里之前,我结束了jquery
//Varible that stores the extra table row
var $adTableRow = "<tr class='addedRow'><td><input type='text' maxlength='5' /></td><td><select name='serviceType' id='serviceType' class='rounded'><option value=''>Choose One...</option><option>Plumbing</option> <option>Drain Cleaning</option><option>Roofing</option><option>HVAC</option><option>Appliance Repair</option><option>Flooring</option> <option>Electrical</option><option>Doors/Windows</option><option>Siding</option><option>Other</option></select></td><td><select name='' class='ad_size'><option value='4.99' class='ad_lg'>Large</option><option value='1.99' class='ad_sm'>Small</option></select></td><td><div class='input-prepend'><span class='add-on'><i class='icon-usd'></i></span><input class='addPrice' value='4.99' type='text' readonly='readonly' /></div></td><td class='options'><i class='icon-remove removeAd' title='Remove This Ad'></i></td></tr>";
$(document).ready(function() {
$('#addTotalBox').val("4.99");
//Assign the right price amount according to users selection
$(".ad_size").on('change', function() {
//Grab the value of the select box and store it in a variable
var ad_cost = $(this).val();
//Insert the value into the pricing box
$(this).parent().next().children().find('.addPrice').val(ad_cost);
//Set the total box to the right price according to ad size
$('input').each(function(index,data) {
var value = $(this).val();
});
});
$('.addRow').on('click', function() {
$("#adsTable").append($adTableRow);
firstRow = false;
//var addedAdPrice = $(this).parent().prev().children().find('.addPrice').val();
});
});
感谢您的提前帮助

根据我上面的评论,您需要将逻辑放入函数中,然后在添加新行时重新初始化该函数。
function reInit(){
$(".ad_size").on('change', function() {
console.log('test');
//Grab the value of the select box and store it in a variable
var ad_cost = $(this).val();
//Insert the value into the pricing box
$(this).parent().next().children().find('.addPrice').val(ad_cost);
//Set the total box to the right price according to ad size
$('input').each(function(index,data) {
var value = $(this).val();
});
});
}
然后,打电话给:
$('.addRow').on('click', function() {
$("#adsTable").append($adTableRow);
firstRow = false;
reInit();
//var addedAdPrice = $(this).parent().prev().children().find('.addPrice').val();
});
