我有两个循环:
typeid.data[i].TypeId
填充下拉列表,在最后一个下拉列表中添加一个选择我的下拉列表没有根据其记录填充,我也不知道为什么。
var selectinnerhtml = "<span><select id = \"answer" + QuestionId + "\" name = \"answer" + QuestionId + "\" class=\"answer" + QuestionId + " form-control input-small\" > </select></span>";
$.ajax({
type: "GET",
dataType: 'json',
contentType: 'application/json; charset=utf-8',
url: '/MYaPI/EmployeeDetails/' + data[i].TypeId,
success: function(datasa) {
var optionhtmls = '<option value="' +
0 + '">' + "--Select--" + '</option>';
$(".answer" + QuestionId).append(optionhtmls);
$.each(datasa, function(j) {
var optionhtmls = '<option value="' +
datasa[j].Oid + '">' + datasa[j].Title + '</option>';
$(".answer" + QuestionId).append(optionhtmls);
});
}
});
var newRows2select = "<tr class='rows'><a href = '' >" +
" <td QuestionCategoryTitle = " + selectdata.QuestionCategoryTitle + " QuestionHeader = " + selectdata.QuestionHeader + " ContentTypeId=" + selectdata.FkSource + " QuestionTypeId=" + selectdata.FkQuestionType + " QuestionOID=" + selectdata.QuestionOid + " CategoryOID=" + selectdata.FkQuestionCategory + " class=\"question-block\"><small style=\"color:slateblue;font-weight: bolder;display:none\">CATEGORY: " + selectdata.QuestionCategoryTitle + ",</small>" +
" <i class=\"deleteRow fas fa-trash float-right\"></i> " +
"<p> " + selectdata.QuestionHeader + "</p>" + selectinnerhtml + " </td></a> \"</tr>";
$("#table23").append(newRows2select);
答案 0 :(得分:0)
您正在尝试访问页面上尚未存在的DOM对象。
您正在尝试这样做:
$(".answer" + QuestionId).append(optionhtmls);
但是“ answer” + QuestionId不在页面上。它位于您的变量中。
为什么不先构建选项,然后再构建选择标记?
