To add a comment to a sheet, first create a comment and set some settings for it. Then you can use the add method to set a comment for the specified cell. For example:
Sometimes you want to remove the comment you added, as shown in the following example:
After you add a comment to a cell, you can use the get method to get the comment, or use the all method to get all the comments in the sheet.
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
initSpread(spread);
};
function initSpread(spread) {
var sheet = spread.getSheet(0);
sheet.addSpan(1, 1, 1, 6);
sheet.setValue(1, 1, "there is a comment on the upper right corner of the cell");
sheet.comments.add(1, 1, "new comment!");
document.getElementById("btnAddComment").addEventListener('click',function () {
var row = parseInt(document.getElementById("txtRowIndex").value);
var col = parseInt(document.getElementById("txtColumnIndex").value);
var spreadNS = GC.Spread.Sheets;
var sheet = spread.getSheet(0);
sheet.setValue(row, col, 'new comment');
var text = document.getElementById("txtComment").value;
sheet.comments.add(row, col, text);
})
};
