这是一个由 CodeCharge（代码生成器）生成的脚本，作为我的应用程序的一部分（当然，显然也是由 Artisteer 设计的）。我对web开发知之甚少，JS零知识，不得不使用这个代码生成器。脚本不断出现此错误：“Line: 139, Char: 13, Error: Unable to get property 'parent' of undefined or null reference, Code:0, URL: )。就像我说的，我无法控制在生成这个脚本后，我可以去修改它，希望能解决这个问题。下面是完整的脚本。第 139 行是：
var s = c.parent().children('.art-layout-cell:not(.art-content)');
这是完整的脚本：
