如何使用 JavaScript 中的脚本在 InDesign 中创建自动目录

Question

我有以下代码，非常适合将 excel 导入 InDesign 并创建自动网格目录。

var doc = app.activeDocument;

// get a text from the XLSX file
var inputFile = File("~/Desktop/test.xlsx");
var temp_frame = doc.textFrames.add();
temp_frame.place(inputFile);
var text = temp_frame.parentStory.contents;
temp_frame.remove();

// make a table from the text
var rows = text.split('\r');
var table = [];
for (var i = 1; i < rows.length; i++) table.push(rows[i].split('\t'));

// width and height of cards, gaps, properties of the grid
var card_width = 70;
var card_height = 80;
var gap = 5;
var cols = 2;
var rows = 3;
var cards_per_page = cols * rows;

// calculate and add pages
var cards = table.length;
var pages_to_add = Math.ceil(cards / cards_per_page) - 1;
while(pages_to_add--) doc.pages.add();

var page_num = 0; // start page
var start_point = [10,10]; // start point for a first card on a page

main_loop:
for (var i = 0; i < cards; i++) {

    for (var row = 0; row < rows; row++) {

        for (var col = 0; col < cols; col++) {

            // break the loop if there is no more rows in the table
            if (table.length == 0) break main_loop;

            var table_row   = table.shift(); // take a first row from the table
            var title       = table_row[0];
            var description = table_row[1];
            var price       = table_row[2];

            // make a card
            var card = make_card(title, description, price);

            // send the card to the some page and move at some place
            card.move(doc.pages[page_num]);
            card.move(start_point);
            card.move(undefined, [(card_width + gap)*col, (card_height + gap)*row]);
        }
    }

    if (i > (page_num-1) * cards_per_page) page_num++; // increase the page number

}


// the function to create and return a card
function make_card(title, description, price) {
    var doc = app.activeDocument;

    var title_frame = doc.textFrames.add();
    title_frame.geometricBounds = [20, 80, 30, 150];
    title_frame.contents = title;

    var description_frame = doc.textFrames.add();
    description_frame.geometricBounds = [30, 80, 80, 150];
    description_frame.contents = description;

    var price_frame = doc.textFrames.add();
    price_frame.geometricBounds = [80, 80, 100, 150];
    price_frame.contents = price;

    var group = doc.groups.add([title_frame, description_frame, price_frame]);
    return group;
}

但是如果我想要 3 页呢？每个页面都会有不同的模板第 1、4、7 页...将有此模板第 2、5、8 页 ... 第 3、6、9 页 ... 将使用网格模板我不知道如何在 javascript 中解决它。

这是模板 IDML：https://app.box.com/s/muqvroawbwv8zydwdizfc3xsmyzmenmy

代码如下：

var doc = app.activeDocument;

// get a text from the XLSX file
var inputFile = File("~/Desktop/test.xlsx");
var temp_frame = doc.textFrames.add();
temp_frame.place(inputFile);
var text = temp_frame.parentStory.contents;
temp_frame.remove();

// split the text by rows
var rows = text.split('\r');
rows.shift(); // remove the first row (a header of the table)

// add pages if there is more than 10 rows
var i = rows.length - 10;
while (i > 0) {
    doc.pages[0].duplicate(LocationOptions.AT_END);
    i -= 1; if (i < 0) break;
    doc.pages[1].duplicate(LocationOptions.AT_END);
    i -= 5; if (i < 0) break;
    doc.pages[2].duplicate(LocationOptions.AT_END);
    i -= 4;
}

// fill all the text frames with texts from the rows
var frames = doc.textFrames;
var i = 0;
while (rows.length > 0) {
    var row = rows.shift().split('\t');
    frames[i++].contents = row[0]; // title
    frames[i++].contents = row[1]; // text
    frames[i++].contents = row[2]; // price
}

// remove empty frames
while (frames.length > i) frames[i].remove();

脚本将 Excel table 中的文本放入模板的文本框架中。如果超过 10 行，脚本将添加页面。

脚本取决于模板中帧的顺序。它填充从第一页上的第一帧[0]到最后一帧的帧。如果您更改顺序，文本将出现在错误的位置。

这是前 10 个 rows/cards 的填充方式：
