js如何控制css
1、直接设置Style对象:
el.style.color = '#b50029'; el.style.fontSize = '30px'; el.style['font-size'] = '30px';
2、设置style属性:
el.setAttribute('style', 'color: red;'); el.setAttribute('style', 'font-size: 30px'); el.setAttribute('style', 'font-size: 30px'); el.setAttribute('style', 'color: red;' + 'font-size: 30px;' + 'background-color: green');
3、设置cssText(相关课程推荐:JS视频教程)
el.style.cssText = "color: red;font-size: 30px"; el.style.cssText = "color: red;font-size: 30px"; el.style.cssText += 'background-color: yellow'; el.style.cssText = "color: red;font-size: 30px"; el.style.cssText += 'background-color: yellow'; el.style.cssText = "text-decoration: line-through";
4、改变class类名
el.className = 'cNone'; el.className += 'cNtwo'; >> el[class="cNone cNtwo"] el.className = 'cNone'; el.className = 'cNtwo'; >>el[class="cNtwo"]
