我得到了json值,我在rentFeatureOption上循环。这部分工作。
{
"bailId": 2,
"fromDate": "2016-03-11",
"toDate": null,
"lodgerId": 1,
"supportTwoPerson": false,
"lodgerPayforTwo": false,
"roomId": 1,
"appartmentId": 1,
"price": 500.0,
"paymentPeriod": "WEEK",
"address": "460 Ch. Chambly, Longueuil, 1",
"rentFeatureOption": [{
"rentFeatureOptionId": 1,
"featureOptionId": 2,
"price": 5.0
}]
}
我需要在html表上循环
<tbody>
<tr data-index="0" data-rent-feature-option-id="">
<td style="" data-feature-option-id="1">Air climatisé
<input type="hidden" name="rentFeatureOption[0].rentFeatureOptionId" value="">
<input type="hidden" name="rentFeatureOption[0].featureOptionId" value="1">
</td>
<td style="">
<input type="text" name="rentFeatureOption[0].price" value="">
</td>
</tr>
<tr data-index="1" data-rent-feature-option-id="">
<td style="" data-feature-option-id="2">Internet
<input type="hidden" name="rentFeatureOption[1].rentFeatureOptionId" value="">
<input type="hidden" name="rentFeatureOption[1].featureOptionId" value="2">
</td>
<td style="">
<input type="text" name="rentFeatureOption[1].price" value="">
</td>
</tr>
</tbody>
for (var i = 0; i < data.rentFeatureOption.length; i++) {
$('#lodgerRentOptionTableResult > tbody > tr').each(function() {
if ($(this).find('td')[0].data("feature-option-id") == data.rentFeatureOption[i].featureOptionId) {
}
});
}
条件我收到此错误
未捕获TypeError:$(...)。find(...)[0] .data不是函数
答案 0 :(得分:2)
[0]
返回一个dom元素。您可以改为使用.first()
或eq(0)
。
您也可以使用一次选择器而不是两个选择器:
$('#lodgerRentOptionTableResult > tbody > tr > td:first-of-type').each(function() {
if( $(this).data("feature-option-id")==data.rentFeatureOption[i].featureOptionId){
