我有一個HTML頁面，當我改變選擇它得到這樣如何將新選項添加到jQuery中的選擇？
{"subCategories":{"433":"belt"},"products":{"435":{"Titre":"Ceinture r\u00e9versible unie 100% cuir","Modele":"CIBOBELT","Couleurs":0,"Marque":"CELIO","Prix":25.99,"PrixBarre":null,"ProductsId":435,"item":{"1":1,"2":2,"3":3,"4":4,"5":5},"arrayTaille":["TU"]},"436":{"Titre":"Coffret ceinture porte-cl\u00e9s et porte-cartes rayure","Modele":"CIBOTTOMAN","Couleurs":0,"Marque":"CELIO","Prix":35.99,"PrixBarre":null,"ProductsId":436,"item":{"1":1,"2":2,"3":3,"4":4,"5":5},"arrayTaille":["T1","T2","T3"]},"433":{"Titre":"Bo\u00eete cadeau ceinture","Modele":"BEBFLOCON","Couleurs":0,"Marque":"CELIO CLUB","Prix":30,"PrixBarre":null,"ProductsId":433,"item":{"1":1,"2":2,"3":3,"4":4,"5":5},"arrayTaille":["TU"]},"434":{"Titre":"Bo\u00eete cadeau ceinture","Modele":"BEBSCHUSS","Couleurs":0,"Marque":"CELIO CLUB","Prix":30,"PrixBarre":null,"ProductsId":434,"item":{"1":1,"2":2,"3":3,"4":4,"5":5},"arrayTaille":["TU"]}}}
和JSON數據時我得到的數據，我追加div 3選擇：
- 名稱：項目=數量
- 名稱：arrayTaille =尺寸
- 名稱：=尺寸，這是一個最一切時間= NULL
，這是形象的人進一步解釋：
的問題是沒有選擇工作。
這是我的JS代碼：
$("#categorySelected").change(function() {
var category = $("#categorySelected :selected").val();
$("#Products").html("");
$("#subCategorySelected option").remove();
$.ajax({
type: 'get',
url : Routing.generate('front_office_get_category', {baseDomaine : baseDomaineJS , _locale: 'en',category:category}),
success: function(data) {
$("#subCategorySelected").append($('<option value="0">Choisir une sous catégorie</option>'));
$.each(data.subCategories, function(key,value) {
$("#subCategorySelected").append($('<option>',{ value : value , text: value }));
});
var html = "";
$.each(data.products, function(key,value) {
html+='<form action="#" method="POST" id="'+key+'"><input type="hidden" name="idProduct" value="'+key+'"><div class="col-md-4 col-sm-6 hero-feature"><div class="thumbnail"><a href="#" data-toggle="modal" data-target="#modal-pdt"> <img src="http://placehold.it/800x500" alt=""></a><div class="caption"><h3 class="media-heading">'+value.Titre+'</h3><p>'+value.Modele+'- '+value.Couleurs+'- '+value.Marque+'<br/></p><p><b>'+value.Prix+'</b><br/><b> </b></p><div class="row margin-bottom-10"><div class="col-xs-12 col-lg-12 margin-bottom-10"><select class="form-control" id="selectedItemm/'+value.ProductsId+'"></select></div><div class="col-xs-12 col-lg-12"><select class="form-control"><option>Dimension</option><option> 2</option><option> 3</option><option> 4</option></select></div></div><div class="row"><div class="col-xs-12 col-lg-4 margin-bottom-10"><select class="form-control" name="qte" id="selectedItem/'+value.ProductsId+'"></select></div><div class="col-xs-12 col-lg-8"><a href="#" id="'+key+'" name="add_panier_btn" class="btn-block btn btn-success">Réserver en magasin</a></div></div></div></div></div></form>';
$("#Products").html(html);
});
$.each(data.arrayTaille, function(key,value) {
$("#selectedItemm/"+value.ProductsId+"").append($('<option>',{ value : key , text: value }));
});
}
});
});
你問，當你改變下拉的值，則不會觸發事件？ 在上面的JSON對象中，沒有'arrayTaille'。 （查看最後一個循環） – Nabid
所有事件都可以很好地工作，但是選擇項目和數組無法工作，它不會追加任何東西 –
您能分享HTML代碼嗎？ – trincot
