如何检查使用$(function AddItemsToCart() {
$('#AddToCartBtn').click(function () {
var cartData = new Array();
if ($("#PartsTable> tr").length > 0) {
var popupMsgTxt = '';
var counter = 0;
$('#PartsTable').find('tr').each(function () {
var row = $(this);
if (row.find('input[type="checkbox"]').is(':checked')) {
var cartDataInfo = new Object();
var $tds = $(this).find('td');
cartDataInfo["CustomerReference"] = $tds.eq(0).find('div').text();
cartDataInfo["Quantity"] = $tds.eq(2).find('div').text();
var $hidden_fields = $(this).find('input:hidden');
cartDataInfo["ItemID"] = $hidden_fields.eq(1).val();
cartDataInfo["ItemCode"] = $hidden_fields.eq(0).val();
popupMsgTxt = $tds.eq(0).find('div').text();
cartData[counter] = cartDataInfo;
counter = counter + 1;
}
});
var cartDataArray = { 'cartData': cartData };
var fleetGuid;
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "OrderFormServices.asmx/AddItemsToCart",
data: JSON.stringify(cartDataArray),
dataType: "json",
success: function (result) {
fleetGuid = result.d;
doWork();
console.log(fleetGuid);
}
});
function doWork(){
var items = [], options = [];
//Iterate all td's in first column
$('#PartsTable tr td:nth-child(1)').each(function () {
items.push($(this).text());
});
//restrict array to unique fleet numbers
items = $.unique(items);
//iterate unique array and build array of select options
$.each(items, function(i, item) {
//// THIS IS WHERE I AM GETTING THE 'UNDEFINED' ERROR ////
options.push('<tr><td align="left" valign="top">' + item + '</td><input type="hidden" name="GUID" value="'+ fleetGuid +'"><td class="delete" align="center" style="background-color: transparent;"><i class="fa fa-times text-red cur-pon"></i></td></tr>');
});
//finally empty the select and append the items from the array
$('#OrderSummaryTbody').append(options.join());
$("#PopupInnerTextModel").text(popupMsgTxt);
$("#popup").fadeIn(750).delay(1750).fadeOut(500);
}
}
});
});
插入集合的值是否已成功保存？
MongoTemplate在MongoTemplate中插入，保存或任何方法都不会返回true或false。
答案 0 :(得分：0)
这里会抛出一个异常是方法流程：
template.insert(object)
|
|
templateinsert(Object objectToSave, String collectionName)
|
|
protected <T> void doInsert(String collectionName, T objectToSave, MongoWriter<T> writer)
|
|
protected Object insertDBObject(final String collectionName, final DBObject dbDoc, final Class<?> entityClass)
|
|
这是insertDBObject的源代码
protected Object insertDBObject(final String collectionName, final DBObject dbDoc, final Class<?> entityClass) {
if(LOGGER.isDebugEnabled()) {
LOGGER.debug("Inserting DBObject containing fields: {} in collection: {}", dbDoc.keySet(), collectionName);
}
return this.execute(collectionName, new CollectionCallback() {
public Object doInCollection(DBCollection collection) throws MongoException, DataAccessException {
MongoAction mongoAction = new MongoAction(MongoTemplate.this.writeConcern, MongoActionOperation.INSERT, collectionName, entityClass, dbDoc, (DBObject)null);
WriteConcern writeConcernToUse = MongoTemplate.this.prepareWriteConcern(mongoAction);
WriteResult writeResult = writeConcernToUse == null?collection.insert(new DBObject[]{dbDoc}):collection.insert(dbDoc, writeConcernToUse);
MongoTemplate.this.handleAnyWriteResultErrors(writeResult, dbDoc, MongoActionOperation.INSERT);
return dbDoc.get("_id");
}
});
}
在写入失败时会抛出异常，它们是运行时异常。运行时激活由MongoExceptionTranslator翻译 。任何不抛出任何异常的插入都是成功的。
