在 MS Word Office.js 插件中实现键盘快捷键

Question

I'm trying to implement a feature in a Word add-in where I track what the user typing in MS Word and then perform automatic replacements. For example, the user could type

:smile: :frown:

and I would automatically replace them with

:) :(

I've implemented a handler to receive documentSelectionChanged events, and I'm currently using the following event handler:

function refLabelShortcut() {
  var range, results, par;
  Word.run(function (context) {
    range = context.document.getSelection();
    range.paragraphs.load('items');
    return context.sync()
    .then(function() {
      par = range.paragraphs.items[0];
      console.log(par.text); // THIS WORKS!
      results = par.search('the*', {matchWildCards: true});
      //results = par.search('the');
      results.load('items'); // SOMETHING WRONG HERE?
      console.log('1');
    })
    .then(context.sync)
    .then(function() {
      console.log('2a'); // DOESN'T GET TO THIS LINE :(
      console.log(results.items.length);
      console.log('2b');
    });
  });
}

The above code works when the search isn't a wildcard one. I've commented out the non-wildcard search so you can see what does work.

When you do the wildcard search, the console shows:

[text of the matching paragraph]
1

and that's it. So the code doesn't get to the last then function.

Any idea why this doesn't work with a wildcard search? Is there a mistake with the results.load('items') line?

Range.paragraphs is a collection object, you can't load a collection object, so range.load('paragraphs') doesn't do anything. In order to read the items of the paragraph collection, you have to load the items (or some property of the paragraph object). Try:

range.paragraphs.load('items');
