Document Theme

SpreadJS supports themes that let you define the overall style, including setting fonts and colors.

<p>SpreadJS provides built-in themes. You can use the <strong>currentTheme</strong> method to get and set the current theme for the sheet, for example:</p> <pre><code class="hljs js language-js"> <span class="hljs-keyword">var</span> spread = GC.Spread.Sheets.findControl(<span class="hljs-built_in">document</span>.getElementById(<span class="hljs-string">'ss'</span>)); <span class="hljs-keyword">var</span> sheet = spread.getActiveSheet(); sheet.currentTheme(GC.Spread.Sheets.SpreadThemes.civic); </code></pre> <p>You can use the theme colors or standard colors to set cells' <strong>foreColor</strong> or <strong>backColor</strong> methods, as shown in this example.</p> <pre><code class="hljs js language-js"> <span class="hljs-keyword">var</span> spread = GC.Spread.Sheets.findControl(<span class="hljs-built_in">document</span>.getElementById(<span class="hljs-string">'ss'</span>)); <span class="hljs-keyword">var</span> sheet = spread.getActiveSheet(); sheet.getCell(<span class="hljs-number">1</span>,<span class="hljs-number">1</span>).foreColor(<span class="hljs-string">'Accent 1 50'</span>); sheet.getCell(<span class="hljs-number">1</span>,<span class="hljs-number">1</span>).backColor(<span class="hljs-string">'Background 2 80'</span>); </code></pre>
