使用vue创建Excel加载项时。 如何根据Excel笔记本上的数据计算属性？

Question

I want to get a list of the names of the sheets to create a drop drop down in my add in. I tried to do it via aa computed property but you cant run async functions to interact whit excel when computing a property. Right now im calling a method when computing the property but I think its not running the code in the excel.run. In the code bellow only the a and the d get pushed to the array.

 computed: { formats: function () { return this.getSheetNames() } }, methods: { getSheetNames () { var sheetNames = ['a'] window.Excel.run(async (context, sheetNames) => { let promise = Promise.resolve(['b']) let list = await promise sheetNames.push(list) sheetNames.push('c') }) sheetNames.push('d') return sheetNames }

Please use the code below:

Window.Excel.run(async(context) {
    var sheets = context.workbook.worksheets;
    sheets.load("items/name");
    var sheetNames = [];
    return context.sync()
        .then(function () {
            if (sheets.items.length > 1) {
                console.log(`There are ${sheets.items.length} worksheets in the workbook:`);
            } else {
                console.log(`There is one worksheet in the workbook:`);
            }
            for (var i in sheets.items) {
                sheetNames.push(sheets.items[i].name); 

            }
        });
})
