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?
答案 0 :(得分:0)
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, 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);
});
