在Word.run流之外使用段落

我试图首先找到一个段落,然后在用户单击按钮时,对该段落进行一些操作。

我尝试使用似乎是权威书籍的示例:迈克尔·兹拉特科夫斯基(Michael Zlatkovsky)的“ Building Office Addins”。

var global_paragraph = undefined;
async function analyzeDocument() {
Word.run(async function(context) {
    const paragraphs = context.document.body.paragraphs;
    context.load(paragraphs, 'text');
    return context.sync().then(() => {
        for (let i = 0; i < paragraphs.items.length; i++) {
        if (/*some condition that works only once*/) {
          global_paragraph = paragraphs.items[i];
          global_paragraph.track();
        }
    };});
}).catch(handleError);
};
async function handleButtonClick() {
    OfficeExtension.config.extendedErrorLogging = true;
    Word.run(global_paragraph, async function(context) {
        global_paragraph.load("text");
        return context.sync().then(() => {
            /* do something */
        });
    }).catch(handleError);
};

这导致了常规异常。

{"code":"GeneralException","message":"GeneralException","errorLocation":"Document._GetObjectByReferenceId","statement":"var v=context.root._getObjectByReferenceId(\"p!00000DB2\");","surroundingStatements":["// >>>>>","var v=context.root._getObjectByReferenceId(\"p!00000DB2\");","// <<<<<","v.load([\"text\"]);"],"fullStatements":["var v=context.root._getObjectByReferenceId(\"p!00000DB2\");","v.load([\"text\"]);"]}

我能够在Script Lab中重现您​​的问题。

我认为问题不在于您的代码,而在于Word API。好消息是,有一个简单的解决方法,尽管我仍然鼓励您在https://github.com/officedev/office-js/issues上提交一个错误,以确保产品团队可以调查一下。

解决方法代替

global_paragraph = paragraphs.items[i];

改为:

global_paragraph = paragraphs.items[i].getRange();

通过调用getRange(),它将创建一个具有正确标识的新对象,从而可以在以后对其进行跟踪。

我在Script Lab中使用的代码段(实际上与您使用的代码段相同)如下:

$("#button1").click(() => tryCatch(button1));
$("#button2").click(() => tryCatch(button2));

var global_paragraph: Word.Range;

async function button1() {
  await Word.run(async function(context) {
    const paragraphs = context.document.body.paragraphs;
    context.load(paragraphs, "text");
    return context.sync().then(() => {
      for (let i = 0; i < paragraphs.items.length; i++) {
        if (paragraphs.items[i].text.startsWith("Dear")) {
          global_paragraph = paragraphs.items[i].getRange();
          global_paragraph.track();
        }
      }
    });
  });
}

async function button2() {
  OfficeExtension.config.extendedErrorLogging = true;
  Word.run(global_paragraph, async function(context) {
    global_paragraph.load("text");
    return context.sync().then(() => {
      console.log(global_paragraph.text);
    });
  });
}

/** Default helper for invoking an action and handling errors. */
async function tryCatch(callback) {
  try {
    await callback();
  } catch (error) {
    // Note: In a production add-in, you'd want to notify the user through your add-in's UI.
    console.error(error);
  }
}

(当然,要对HTML进行相应的更改以添加两个按钮):

<button id="button1" class="ms-Button">
    <span class="ms-Button-label">Button1</span>
</button>

<button id="button2" class="ms-Button">
    <span class="ms-Button-label">Button2</span>
</button>

希望这会有所帮助,
