OfficeJS - 删除和重新排列 Word 文档中的部分 [英] OfficeJS -Delete and rearrange sections in a Word document

问题描述

我想使用 office.js 删除和重新排列 Word 文档的各个部分.例如，一个 Word 文档有 3 个部分.这是部分标题的列表:

I want to delete and rearrange the sections of a Word document using office.js. For example, a Word document have 3 sections. And here is the list of sections headers:

1. 摇滚部分一
2. 摇摆部分二
3. 摇滚乐第三部分

用户将其更改为:

1. 摇滚乐第三部分
2. 摇滚部分一

最后，我想在我的 Word 文档中看到影响.我可以轻松地向用户显示部分标题列表.用户可以更改(重新排列或删除)标题列表.我已经尝试了一种方法来做到这一点.我更改了 sections 的 items 并尝试加载 sections.代码如下:

And finally I want to see the impact in my Word document. I can easily show user the list of headers of sections. And user can change(rearrange or delete) the list of headers. I have tried a way to do this. I changed the items of sections and tried to load the sections. Here is the code:

function RearrangeSections(sectionHeaderList) {
    Word.run(function (context) {

        var sections = context.document.sections;
        context.load(sections);
        return context.sync()
            .then(function () {
                if (sections != null) {                        
                    var headers = [];
                    for (var i = 0; i < sections.items.length; i++) {

                        // Grab the header from the current section
                        var header = sections.items[i].getHeader('primary');

                        // Add loading this header to the  queue 
                        context.load(header);

                        // Push this header into the headers collection
                        headers.push(header);
                    }


                    var sectionItems = sections.items; //Get section items into a new list
                    context.sync().then(function () {
                        for (var i = 0; i < sectionHeaderList.length; i++) { 

                            for (var j = 0; j < headers.length; j++) {
                                var targetHeader = sectionHeaderList[i].name;  //
                                if (headerText == targetHeader) {
                                    context.document.sections.items[i] = sectionItems[j]; // Change the section items
                                }
                            }
                        }
                        context.load(context.document.sections); // Finally load the sections
                        return context.sync().then(function () {
                            //
                        });
                    });
                }

            }).catch(function (myError) {
                //otherwise we handle the exception here!                    
            });


    }).catch(errorHandler);

}

在方法参数中，sectionHeaderList 是一个对象列表，其中包含更新的(用户更改后)标题列表.在这里，我只是尝试重新排列.

In the method parameter, sectionHeaderList is a list of objects which has the updated(after user change) header list. Here I just tried to rearrange.

这段代码不做任何事情.我是否以正确的方式尝试?

This code do not do any thing. Am I trying in a proper way?

推荐答案

我解决了这个问题.我选择了部分正文的 Ooxml ，然后清除文档正文并将部分正文作为我的序列.我使用部分正文的第一行来匹配部分.您可以使用节标题.这也会起作用.示例代码如下:

I solved the problem. I picked the Ooxml of the section bodies and then clear the document body and put the section bodies as my sequence. I used first line of the section body for matching the sections. You may use section header. That will also work. Here is the sample code:

function RearrangeSections(sectionHeaderList) {
    Word.run(function (context) {
        var body = context.document.body;
        var sections = context.document.sections;
        context.load(body);
        context.load(sections);
        return context.sync()
            .then(function () {
                if (sections != null) {
                    var itemsCount = sections.items.length;
                    var bodies = [];
                    var bodiesOoxml = [];
                    for (var i = 0; i < sections.items.length; i++) {

                        var body = sections.items[i].body;
                        context.load(body);                            
                        bodies.push(body);
                    }

                    // Sync/Exectute the queued actions                       
                    var sectionItems = [];
                    sectionItems = sections.items;

                    context.sync().then(function () {
                        for (var i = 0; i < bodies.length; i++) {
                            var ooxml = bodies[i].getOoxml();
                            bodiesOoxml.push(ooxml);
                        }


                        context.sync().then(function () {                                
                            context.document.body.clear();
                            for (var i = 0; i < sectionHeaderList.length; i++) {
                                for (var j = 0; j < bodies.length; j++) {

                                    var bodyText = bodies[j].text;
                                    var headerText = bodyText.split("\r")[0];
                                    var targetHeader = sectionHeaderList[i].name;


                                    if (headerText == targetHeader) {
                                        var val = bodiesOoxml[j].value;
                                        body.insertOoxml(val, Word.InsertLocation.end);
                                    }
                                }
                            }
                            context.load(context.document.sections);
                            return context.sync().then(function () {
                                console.log("Done");
                            })
                        });                            
                    }).catch(function (e) {
                        //Show error

                    });
                }

            }).catch(function (myError) {

                //Show error
            });


    }).catch(errorHandler);

}
