做一个表格列表中整行鼠标移动变色的效果,找了一段现成代码再改了一点,加上鼠标点击变色和再点击变回原色的效果.
一个N行N列的表格,实现鼠标移到某行变色,然后点击某一行使之固定一种颜色,再点使之返回原色.原理是使<tr>保持原色,鼠标事件对<tr>下的<td>样式背景色进行改变.同时可以设置避免变色事件的行,主要是针对标题行.相信这段代码对需要做项目比较多的数据列表的朋友有用,我在google和blueidea都找了一遍,没找到完全现成的.

// 此处clickcolor只能用win系统颜色代码才能成功,如果用#xxxxxx的代码就不行,还没搞清楚为什么:( var clickcolor = ' orange ' ; function changeto(){ source = event.srcElement; if (source.tagName == " TR " || source.tagName == " TABLE " ) return ;
