Calculator

One type of cell drop-down in SpreadJS is the calculator. When added to the workbook as a cell style with Javascript code, the calculator provides users with a means to do quick calculation and have that result be displayed in the cell. The below spreadsheet shows how that works.

<p>Drop-downs provide developers the ability to add a drop-down menu with specific properties to cells in a workbook. These drop-down menus don't require any extra code other than simply specifying which one to use for the drop-down menu. </p> <p>SpreadJS now has 8 different kinds of drop-downs, and this demo shows how to use the Calculator.</p> <p>You can use calculator drop-down like the following code :</p> <pre><code class="hljs js language-js"> <span class="hljs-comment">// The way of click the dropdown icon to open calculator. </span> <span class="hljs-keyword">let</span> style = <span class="hljs-keyword">new</span> GC.Spread.Sheets.Style(); style.cellButtons= [{ <span class="hljs-attr">imageType</span>: GC.Spread.Sheets.ButtonImageType.dropdown, <span class="hljs-attr">command</span>: <span class="hljs-string">"openCalculator"</span>, } ]; sheet.setStyle(<span class="hljs-number">1</span>, <span class="hljs-number">0</span>, style); sheet.setText(<span class="hljs-number">0</span>, <span class="hljs-number">0</span>, <span class="hljs-string">"Calculator"</span>); <span class="hljs-comment">// The way just open calculator with command rather then clicking the dropdown button.</span> spread.commandManager().execute({<span class="hljs-attr">cmd</span>:<span class="hljs-string">"openCalculator"</span>,<span class="hljs-attr">row</span>:<span class="hljs-number">5</span>,<span class="hljs-attr">col</span>:<span class="hljs-number">5</span>,<span class="hljs-attr">sheetName</span>:<span class="hljs-string">"Sheet1"</span>}); </code></pre>
var spreadNS = GC.Spread.Sheets; window.onload = function () { var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss")); initSpread(spread); }; function initSpread(spread) { var sheet = spread.getSheet(0); sheet.suspendPaint(); var style = new GC.Spread.Sheets.Style(); style.cellButtons = [ { imageType: GC.Spread.Sheets.ButtonImageType.dropdown, command: "openCalculator", useButtonStyle: true, } ]; sheet.setText(4, 5, "Calculator"); sheet.setStyle(5, 5, style); sheet.resumePaint(); spread.commandManager().execute({cmd:"openCalculator",row:5,col:5,sheetName:"Sheet1"}); }
