Office.js获取与内容控件相邻的范围

我有以下情形Word:

  • 带有一些内容控件的文本文档(也包括文本)
  • 内容控件始终与普通文本相邻(文本和内容控件之间没有空格)
  • 内容控件在创建时与相邻文本具有相同的样式(通过编辑其font.colorfont.namefont.size等),这些内容是从内容选择中读取的控件被插入)
  • 更新内容控件(更新其内容)时,其样式将重置,我需要再次应用文档样式(不是问题,可以正常工作)

问题在于,当内容控件更新时,当前文档的选择可以在任何地方,但是我需要确保它们重新应用与相邻文本相同的样式。

Office.js内是否有一种方法来获取与内容控件相邻的范围?这样,我就可以阅读它的样式并将其应用于内容控件。

答案 0 :(得分:1)

我的假设是,您希望文本紧接在内容控件之前。不幸的是,对象模型没有提供等效于a.map的“后退”(getNextTextRange)。

可以做到,但是有点麻烦。以下是我的脚本实验室示例代码:

getPreviousTextRange

在最后一个单词和内容控件之间有空格的情况下的代码:

async function
    getAdjacentRange() {
    await Word.run(async (context) => {

        var ccs = context.document.contentControls;
        ccs.load("items");
        await context.sync();
        console.log("Nr cc: " + ccs.items.length);
        let cc = ccs.items[0];

        //The starting point of the content control so that 
        //the range can be extended backwards          
        let ccRange = cc.getRange("Start");
        let ccParas = ccRange.paragraphs; cc.load("text,range,paragraphs");
        let ccPara = ccParas.getFirst();
        ccParas.load("items")

    //The content control must be in a paragraph: get that paragraph's
    //starting point so that the range can be extended in that direction
        let paraRange = ccPara.getRange("Start");
        let rng = paraRange.expandTo(ccRange);
   //Get the words in the range of the start of the paragraph to the 
   //start of the content control in order to get the last one before the content control
        let em = [" "];
        let words = rng.getTextRanges(em, true);
        words.load("items");
        await context.sync();
        let nrWords = words.items.length;

      //minus 2 to get second to last word since last word is directly adjacent to content control (no space)
        let lastWord = words.items[nrWords - 2];

        //Now get the content from the end of the second to last word to
        //the start of the content control, which will be the last word
        let word2BeforeCC = lastWord.getRange("End");
        let wordBeforeCC = word2BeforeCC.expandTo(ccRange);
        wordBeforeCC.load("text");
        await context.sync();
        console.log(cc.text + "/ Word before the content control: " + wordBeforeCC.text + " / nr Words: " + nrWords);
})
    }
