单个圆形链表排序(Sorting singly circular linked list)

 我想在每次编辑后对单个循环链表进行排序。 但我的代码不起作用。 我基于选择排序算法。 我已经这样做了好几个小时但似乎无法获得正确的代码。  
void editList(node *head, int value, int newValue)
{
    node *traverser = head;
    do {
        traverser = traverser -> next;
    }while(traverser -> data != value);

    traverser -> data = newValue;

    node *index;
    node *selection;
    node *temp = new node;

    for(index = head; index -> next != head; index = index -> next) {

        for(selection = head; selection -> next != head; selection = selection -> next) {
            if(index -> data > selection -> data) {
                temp -> data = index-> data;
                index -> data = selection -> data;
                selection -> data = temp -> data;

            }
        }//End of outer loop

    }//End of sorting

    return;
}//End of editList()

I'm trying to sort the singly circular linked list after each edit. But my code doesn't work. I based it on the selection sort algorithm. I've been doing this for hours but can't seem to get the correct code. 
void editList(node *head, int value, int newValue)
{
    node *traverser = head;
    do {
        traverser = traverser -> next;
    }while(traverser -> data != value);

    traverser -> data = newValue;

    node *index;
    node *selection;
    node *temp = new node;

    for(index = head; index -> next != head; index = index -> next) {

        for(selection = head; selection -> next != head; selection = selection -> next) {
            if(index -> data > selection -> data) {
                temp -> data = index-> data;
                index -> data = selection -> data;
                selection -> data = temp -> data;

            }
        }//End of outer loop

    }//End of sorting

    return;
}//End of editList()

 似乎你过早地调用generatePost（）函数（当文档加载时，但同时，这也是当你加载jQuery时...为什么你得到了“）”缺少错误..）。  
 所以我将HTML更改为：  
<head>
</head>
<body>
    <main>
        <div class="container">
            <div id="postcontainer">

            </div>
        </div>
    </main>
</body>
 
 而jQuery：  
$(document).ready(function() {
        function generatePost(title, time, text) {
        var postCount = 0;
        $('#postcontainer').append('<div id=' + "post_" + postCount +  '></div>').attr('class', 'content');
        $('#post_' + postCount).append('<h3>' + title + '</h3>').attr('id', 'post_h3_' + postCount);
        $('#post_h3_' + postCount).append('<span>' + time + '</span>');
        var paragraphs = text.split("||");

        for (var i = 0; i < paragraphs.length; i++) {
            var paragraphCount = 0;
            $('#post_' + postCount).append('<p>' + paragraphs[i] + '</p>').attr('id', 'post_p_' + postCount + '_' + paragraphCount);
            paragraphCount++;
        }
        postCount++;
    }  
         generatePost("Testing Title", "I don't know", "This is || a paragraph"); 
});
 
 只需在document.ready结束时调用该函数。 此外，正如您所看到的，我还遇到了一些关于如何分配帖子ID的问题，所以最后也将其切换为一个简单的字符串插值。  
 干杯，

Seems you were calling the generatePost() function too early (when document loads, but at the same time, thats also when you load your jQuery... why you were getting the ")" Missing error..).  
So I changed the HTML to:  
<head>
</head>
<body>
    <main>
        <div class="container">
            <div id="postcontainer">

            </div>
        </div>
    </main>
</body>
 
And the jQuery to:  
$(document).ready(function() {
        function generatePost(title, time, text) {
        var postCount = 0;
        $('#postcontainer').append('<div id=' + "post_" + postCount +  '></div>').attr('class', 'content');
        $('#post_' + postCount).append('<h3>' + title + '</h3>').attr('id', 'post_h3_' + postCount);
        $('#post_h3_' + postCount).append('<span>' + time + '</span>');
        var paragraphs = text.split("||");

        for (var i = 0; i < paragraphs.length; i++) {
            var paragraphCount = 0;
            $('#post_' + postCount).append('<p>' + paragraphs[i] + '</p>').attr('id', 'post_p_' + postCount + '_' + paragraphCount);
            paragraphCount++;
        }
        postCount++;
    }  
         generatePost("Testing Title", "I don't know", "This is || a paragraph"); 
});
 
Just calling the function at the end of the document.ready. Also, as you can see, I also ran into some issues about how the post's id was being assigned, so ended up switching that up as well, assigning it with some simple string interpolation.  
Cheers,
