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:

似乎c没有实例化,类似于c = new 任何东西

看起来你可能jQuery.noConflit()在你的项目中使用过,所以$不是jQuery对象。

所以改变

var c = $('div.art-content');

var c = jQuery('div.art-content');
