Question

我有一个字符串，其中包含每个部分的标题和页数，如下所示：

    string = "section1;section2;section3;section4|2 3 1 4"

我希望能够创建一个部分索引并使用标题作为整个文档中相应页面的链接。

有什么建议吗？我最初的想法是将字符串拆分为节标题和页面计数，然后拆分它们并将标题附加到无序列表？这将照顾部分标题，但页面计数呢？

    var options = string.split('|');

    var sections = options[0];

    var section_titles = sections.split(';');

    for (a=0;a<section_titles.length;a++){
    $('ul').append('<li><div class="title">'+sections[a]+'</div></li>');
    };

    var counts = options[1];

    var section_counts = counts.split(' ');

    ???????

请发送您的建议。

如果您的应用程序是一个Web应用程序而您没有尝试在pdf文档中创建索引，这将有所帮助。

最简单的方法是使用锚点和链接。

请阅读这些： link anchor

然后看下面的完整代码示例。您可以在test.html文件中复制所有文件，然后在浏览器中打开它以查看其行为。

<body>

<script type="text/javascript">
document.write("\<script src='http://code.jquery.com/jquery-latest.min.js' type='text/javascript'>\<\/script>");
</script>
<style>
section{font-size:100px;}
</style>


First things first, your data setup seems odd. If you can change that string's setup, try going the JSON way. For example:
<script>
var jsonString = '{ "section1":2, "section2":3, "section3":1, "section4":4 }';

var objectFromJson = jQuery.parseJSON(jsonString);
var ul = $('<ul>'); 
for (var prop in objectFromJson)
{
    var li = $("<li>");
    var divTitle = $("<div>");
    divTitle.addClass("title");
    var titleLink = $("<a>");
    titleLink.text(prop);
    titleLink.attr("href","#" + prop + "/" + objectFromJson[prop])
    divTitle.append(titleLink)
    li.append(divTitle);
    ul.append(li);
    }
$("body").append(ul);
</script>

If that is not possible, let's continue on what you have
<script>
var str = "section1;section2;section3;section4|2 3 1 4"
var options = str.split('|');

var sections = options[0];
var numbers = options[1];

var section_titles = sections.split(';');
var numbersArr = numbers.split(' ');

var ul = $('<ul>'); 
for (var a=0; a < section_titles.length; a++)
{
    if(numbersArr.length > a)
    {
        var li = $("<li>");
        var divTitle = $("<div>");
        var titleLink = $("<a>");
        titleLink.text(section_titles[a]);
        titleLink.attr("href","#" + section_titles[a] + "/" + numbersArr[a])

        divTitle.addClass("title");
        divTitle.append(titleLink)
        li.append(divTitle);
        ul.append(li);
    }
    }
$("body").append(ul);
</script>

Answer 2

这是最终为我工作的......

我将字符串更改为包含＆＃34; title; count＆＃34;由|
我将此输出为无序列表

var str = "section1;2|section2;3|section3;1|section4:4"
var d = 0;
var ul = $('<ul>');
var sec = toc.split('|');
var a = 0;
  for (a = 0; a < sec.length; a++) {
var secArr = sec[a].split(';');
  var sectiontitle = secArr[0];
  var sectioncount = secArr[1] * 1;
var jump = d;
d = d + sectioncount;
  if (sectiontitle == ''){
  } else {
  $('#sections').find('ul').append('<li><div class="toc"><div     class="title">'+sectiontitle+'</div></div><span class="jumper"
style="display:none;">'+jump+'</span></li>');
  }
  }
