问题描述
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?
解决方法
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
-
获取文档正文的OOXML
-
解析OOXL.value并生成xmlDocument(xmlDoc)
-
检测包含文本的现有文本框和形状:getElementsByTagName(“ wps:wsp”)
-
从(3)中提取文本
-
生成一个提取了文本的简单xml TextElement
-
用(5)代替(3)
-
将更新后的xmlDoc序列化为xmlString并获取更新后的OOXML.value
-
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,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); });
