第一篇文章,长时间的观察。 Stack Overflow ROCKS!
需要一些帮助。我主要是商业智能/数据仓库专业人士。我需要使用一些Javascript在报表编写工具中创建折叠行报表,我无法预料到调用JQuery(内部LAN部署)的能力。因此我需要纯粹的Javascript。
前提是我需要仅在经理/区级别打开报告,但能够打开区域群集以查看分配的销售代表及其贡献。
我找到了执行此操作的代码(实际上通过隐藏重复的区域管理器的名称很好),但它使用文本对象(“+”和“ - ”)来呈现OnClick事件后面的链接。我真的,真的,真的,真的需要让它显示交替的图像。
我尝试简单地修改这两个部分,但是在第一个块中渲染图像的代码与第二个块的代码不匹配,这会导致三元操作失败并且图像不会按预期交替。
lnk.innerHTML =(lnk.innerHTML == "+")?"--":"+";
var link ='<a href="#" onclick="toggleSection(this);return false;" style="text-decoration: none">+</a>';
下面的代码包含带有onClick操作文本的工作代码,以及一个用于切换图像的简单onClick。基本上我需要将文件夹图标放在Manager / District网格的第一个单元格中。为了节省空间,我将工作崩溃代码强制进入主Javascript块。
任何帮助,见解,指导,电牛产品冲击(哎哟)都将不胜感激。
提前致谢。
更新:为此创建了一个CodePen,以便更容易看到现在有效:
