Create a section index and jump to page menu from a string

Question

I have a string containing the section titles and page counts per section as follows:

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

i would like to be able to create a section index and use the titles as links to the appropriate pages in the whole document.

any suggestions? My initial thought was to split the string into the section headers and page counts, then split these and append the titles to a unordered list? That would take care of the section titles but what about the page counts?

    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(' ');

    ???????

Please send your suggestions.

If your application is a web application and you are not trying to create an index IN a pdf document, this will help.

Simplest way is to make use of anchors and links.

Read these please: link anchor

Then see full code example bellow. You can copy all of it in a test.html file, then open it in your browser to see how it behaves.

<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

Here's what ended up working for me...

I changed the string to include "title;count" seperated by a |
I am outputing this as an unordered list

 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>'); } }
