使用Word JS Api从文档中删除文本框

我正在尝试从文档中删除文本框,并用其文本替换它们。 我知道Word JS API也不提供直接的方法来处理文本框。 因此,我正在尝试通过更新文档的OOXML或删除所选范围并插入一段文本来做到这一点。

尽管我可以选择“形状”,图片,表格并执行此操作,但一旦涉及到“文本框”或所选对象包含一段文本,我将失败。例如我们在其中添加了一些文字的形状或艺术字。这是我删除范围后使用的代码

Word.run(function (context) {

        let rng = context.document.getSelection();

        return context.sync().then(function () {
            rng.delete();

            return context.sync().then(function () {

                rng.insertText("Foo - Bar", Word.InsertLocation.replace);

                return context.sync().then(function () {
                    console.log('done');
                });

            });
        });
    })

我得到的结果是仅替换了文本,但保留了它的容器(文本框)。 有想法吗?

我终于采取了以下解决方法。在Windows和macO上都可以很好且快速地运行

  1. 获取文档正文的OOXML

  2. 解析OOXL.value并生成xmlDocument(xmlDoc)

  3. 检测包含文本的现有文本框和形状:getElementsByTagName(“ wps:wsp”)

  4. 从(3)中提取文本

  5. 生成一个提取了文本的简单xml TextElement

  6. 用(5)代替(3)

  7. 将更新后的xmlDoc序列化为xmlString并获取更新后的OOXML.value

  8. 插入更新的OOXML.value,以文档替换现有的OOXML.value

    Word.run(函数(上下文){

         //Select document body and extract OOXML 
         const body = context.document.body;
         const ooxml = body.getOoxml();
    
         return context.sync().then(function () {
    
             //Initialize DOM Parser
             const parser = new DOMParser();
             const xmlDoc = parser.parseFromString(ooxml.value, "text/xml");
    
             //Get all runs
             const rows = xmlDoc.getElementsByTagName("w:r");
             for (let j = 0; j < rows.length; j++) {
                 const row = rows[j];
                 const rowHasTextBox = row.getElementsByTagName("wps:txbx").length > 0;
                 //If no textbox, shape, wordart exists skip current run
                 if (!rowHasTextBox) continue;
    
                 //Select textbox, shape, wordart and get paragraphs
                 const textboxContainer = row.getElementsByTagName("wps:txbx")[0];
                 const paragraphs = textboxContainer.getElementsByTagName("w:p");
    
                 // Create a new run which will replace the existing run
                 const newRow = xmlDoc.createElement("w:r");
                 const breakLine = xmlDoc.createElement("w:br");
                 //Append breakline and "{{"
                 newRow.appendChild(breakLine);
                 newRow.appendChild(startRow);
    
                 for (let p = 0; p < paragraphs.length; p++) {
                     //Check whether paragrapj has text
                     const paragraphHasText = paragraphs[p].getElementsByTagName("w:t").length > 0;
                     if (!paragraphHasText) continue;
                     //Extract text
                     let textExtracted = "";
                     const textBoxTexts = paragraphs[p].getElementsByTagName("w:t");
                     for (let k = 0; k < textBoxTexts.length; k++) {
                         const textBoxText = textBoxTexts[k].innerHTML;
                         textExtracted = textExtracted + textBoxText;
                         textExtracted = textExtracted + " ";
                     }
                      // Create a temp run which will hold the etxtracted text
                     const tempRow = xmlDoc.createElement("w:r");
                     const newText = xmlDoc.createElement('w:t');
                     newText.setAttribute("xml:space", "preserve");
                     newText.innerHTML = textExtracted;
                     textExtracted = "";
                     tempRow.appendChild(newText);
                     newRow.appendChild(tempRow);
                     const breakLine = xmlDoc.createElement("w:br");
                     newRow.appendChild(breakLine);
                 }
    
    
                 //Replace existing run with the new one
                 row.replaceWith(newRow);
             }
             //Serialize dom , clear body and replace OOXML
             const serializedXML = new XMLSerializer().serializeToString(xmlDoc.documentElement);
             body.clear();
             return context.sync().then(function () {
                 body.insertOoxml(serializedXML, Word.InsertLocation.replace);
                 console.log('done');
             });
         });
     })
     .catch(error => {
         console.log('Error: ', error);
         resolve(false);
     });
