我有一个包含每个部分的部分标题和页数的字符串，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将标题用作整个文档中相应页面的链接。

有什么建议么？我最初的想法是将字符串拆分为节标题和页数，然后拆分这些并将标题附加到无序列表中？这将处理部分标题，但页数呢？

    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。

这就是最终为我工作的东西......

  • 我将字符串更改为包含由 | 分隔的“title;count”
  • 我将其输出为无序列表
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>');
  }
  }

如果您的应用程序是 Web 应用程序并且您不尝试在 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： 链接 锚

然后查看下面的完整代码示例。您可以将所有内容复制到 test.html 文件中，然后在浏览器中打开它以查看其行为方式。

<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>
