如何使用Office.js从文件系统读取特定文件来加载Word插件

Office.initialize = function() {
  // 初始化插件
};

function loadWordPlugin() {
  Office.context.document.getFilePropertiesAsync(function(result) {
    if (result.status === Office.AsyncResultStatus.Succeeded) {
      var filePath = result.value.url;

      Office.context.document.getFileAsync(filePath, { sliceSize: 65536 }, function(result) {
        if (result.status === Office.AsyncResultStatus.Succeeded) {
          var file = result.value;
          var fileData = [];

          var sliceCount = file.sliceCount;
          for (var i = 0; i < sliceCount; i++) {
            file.getSliceAsync(i, function(result) {
              if (result.status === Office.AsyncResultStatus.Succeeded) {
                fileData = fileData.concat(result.value.data);
              }
            });
          }

          Office.context.document.setSelectedDataAsync(fileData, { coercionType: Office.CoercionType.Text }, function(result) {
            if (result.status === Office.AsyncResultStatus.Succeeded) {
              // 插件加载成功
            }
          });
        }
      });
    }
  });
}
