[英]Display the JSON data in parent-child hierarchical structure
我们想要以父子层次结构显示JSON数据
var JsonArr = [{
"comment":"Comment 1",
"commentID":1,
"parentID":0,
"children":[{
"comment":"Comment 1-2",
"commentID":2,
"parentID":1,
"children":[{
"comment":"Comment 1-2-2",
"commentID":1,
"parentID":2
}]
}]
},
{
"comment":"Comment 2",
"commentID":4,
"parentID":0
}]

任何即时帮助将非常可观。 谢谢。
检查这个小提琴 。
不完全是tree
结构,但我们可以使用css
并传递通过level
信息来模仿它
function showComments(comments,level){//Extra parameter for level information
for(var i = 0; i < comments.length; i++) {
commentsContainer = loadComment(comments[i], commentsContainer,level)//render comment along with level information
if (comments[i]['children'] && comments[i]['children'].length) {
showComments(comments[i]['children'],level+1)//next level for children
}
}
}
function loadComment(commentObj, commentsContainer,level){//level of node
var profileFullName = "Rohit Jindal";
//add some padding multiplied with level for each comment element
var commentHTML = '<div class="commentbox" style="padding-left:'+(level*100)+'px;"><div class="commentphoto"><a href="#123"><img src="https://graph.facebook.com/100000816365798/picture?type=square"></a></div><div class="commentcontent"><a href="#123"><strong>' + profileFullName + '</strong></a> <small>Just now</small><br>' + commentObj.comment + '<br><a name="replyComment" commentid="' + commentObj.commentID + '">Reply</a><span id="votescore-' + commentObj.commentID + '" class="votescore"></span></div></div>';
commentsContainer.append(commentHTML);
return commentsContainer;
}
showComments(JsonArr,0);//call showComment with initial level 0
我已经修改了您的代码。 请看一下小提琴: https : //jsfiddle.net/swaprks/6dcdbks4/2/
JAVASCRIPT:
$(document).ready(function() {
var StmId = $('[name = "StatementId"]').val();
var JsonArr = [{
"comment":"Comment 1",
"commentID":1,
"parentID":0,
"children":[{
"comment":"Comment 1-2",
"commentID":2,
"parentID":1,
"children":[{
"comment":"Comment 1-2-2",
"commentID":1,
"parentID":2
}]
}]
},
{
"comment":"Comment 2",
"commentID":4,
"parentID":0
}]
var commentsContainer = $("<div></div>");
showComments(JsonArr);
function loadComment(commentObj, commentsContainer, isChild){
// console.log(commentObj);
var profileFullName = "Rohit Jindal";
var marginLeft = '';
if ( commentObj.parentID > 0 ) {
marginLeft = 'style="margin-left: '+commentObj.parentID*60+'px;"'
}
var commentHTML = '<div '+marginLeft+' class="commentbox"><div class="commentphoto"><a href="#123"><img src="https://graph.facebook.com/100000816365798/picture?type=square"></a></div><div class="commentcontent"><a href="#123"><strong>' + profileFullName + '</strong></a> <small>Just now</small><br>' + commentObj.comment + '<br><a name="replyComment" commentid="' + commentObj.commentID + '">Reply</a><span id="votescore-' + commentObj.commentID + '" class="votescore"></span></div></div>';
commentsContainer.append(commentHTML);
// console.log(commentsContainer.closest('.commentbox'));
return commentsContainer;
}
function showComments(comments, isChild){
for(var i = 0; i < comments.length; i++) {
// console.log(comments[i]['comment']);
commentsContainer = loadComment(comments[i], commentsContainer, isChild)
if (comments[i]['children'] && comments[i]['children'].length) {
showComments(comments[i]['children'], true)
}
}
}
$('.commentbox').append(commentsContainer);
});
