我的页面中有一个讨论主题，其中一个主题是parentID＆amp;对它的答复是它的孩子。 在装饰HTML时，我从JSON文件中获取数据，其中提到了parentID，如果它是null，则它是父元素，否则child需要在其父ID“li”标记处附加。我无法准确地提供符合我目的的代码。
代码： 脚本：
//Write the data to discussion window
var message = $.parseJSON(data.d);
$("#ui-discussion").html(null);
$.each(message, function (index, item) {
if (item.ParentID == "NULL") {
var content = "<div><div id='empImage'><img src='" + item.emp_thumbnail_src + "'/></div>" + "<div>" +
"<label id='empName'>" + item.Enterprise_Id + "</label><label id='chatdate'>" + item.Date + "</label>" +
"<label>" + item.Display_Text + "</label><label id='discussionID'>" + item.DiscussionID + "</label></div></div>";
$('<li class="ui-discussion-parentmessage">' + content + '</li>').appendTo('#ui-discussion');
}
else {
var content = "<div><div id='empImage'><img src='" + item.emp_thumbnail_src + "'/></div>" + "<div>" +
"<label id='empName'>" + item.Enterprise_Id + "</label><label id='chatdate'>" + item.Date + "</label>" +
"<label>" + item.Display_Text + "</label></div></div>";
$('<ul><li class="ui-discussion-childmessage">' + content + '</li></ul>').appendTo('#ui-discussion');
}
以下是我的HTML：

答案 0 :(得分：0)
将此行$('<ul><li class="ui-discussion-childmessage">' + content + '</li></ul>').appendTo('#ui-discussion');更改为
$('<ul><li class="ui-discussion-childmessage">' + content + '</li></ul>').appendTo('#' + item.ParentID);
您还需要将您的ID提供给父母的<li>。
给予
var message = $.parseJSON(data.d);
$("#ui-discussion").html(null);
$.each(message, function (index, item) {
if (item.ParentID == "NULL") {
var content = "<div><div id='empImage'><img src='" + item.emp_thumbnail_src + "'/></div>" + "<div>" +
"<label id='empName'>" + item.Enterprise_Id + "</label><label id='chatdate'>" + item.Date + "</label>" +
"<label>" + item.Display_Text + "</label><label id='discussionID'>" + item.DiscussionID + "</label></div></div>";
$('<li class="ui-discussion-parentmessage" id="' + item.Enterprise_Id +'">' + content + '</li>').appendTo('#ui-discussion');
} else {
var content = "<div><div id='empImage'><img src='" + item.emp_thumbnail_src + "'/></div>" + "<div>" +
"<label id='empName'>" + item.Enterprise_Id + "</label><label id='chatdate'>" + item.Date + "</label>" +
"<label>" + item.Display_Text + "</label></div></div>";
$('<ul><li class="ui-discussion-childmessage">' + content + '</li></ul>').appendTo('#' + item.ParentID);
}
});
