代码方面也较为简单,核心代码如下。要想实现根据我们选择的单元格位置插入图片,需要获取当前活跃单元格的横纵坐标与行高列宽。读取文件后将其转为base64的形式。最后通过add方法将图片插入到指定的单元格。
startRow = sheet.getActiveRowIndex();
startCol = sheet.getActiveColumnIndex();
rowHeight = sheet.getRowHeight();
colWidth = sheet.getColumnWidth();
file = document.getElementById("fileDemo").files[0];
reader = new FileReader();
reader.readAsDataURL(file); /*当读取操作成功完成时调用*/ //异步读取文件内容,结果用data:url的字符串形式表示
reader.onload = function (e) {
timestamp = Date.parse(new Date());
picture = sheet.pictures.add(
timestamp.toString(),
this.result,
startCol * colWidth,
startRow * rowHeight
);
};
下载附件即可查看完整demo。
整体实现效果如下:
