jQuery选择器无法与[]一起使用 [英] jquery selector not working with [ ]

问题描述

我正在使用jQuery在osCommerce实例中处理表单数据，但在选择某些元素时遇到了麻烦.

I'm using jQuery to manipulate form data in an osCommerce instance and I'm having trouble selecting some elements.

该脚本生成ID为product_description [N]的文本区域，N为1，2，3 ...

The script generates textareas with the id product_description[N], N being the 1, 2, 3...

问题在于，其中带有[]的id值会使jQuery(甚至是常规脚本)无法选择该元素，并且我无法使用它.

The problem is that having an id value with [] in it makes jQuery (even regular script) not to select the element and I can't work with it.

我尝试将id切换为下划线，处理信息，然后将其更改回[]，但我什至不能这样做:

I tried switching the id to underscores, manipulate the information and then change it back to [ ] but I can't even do:

$('#product_description[1]').attr('id','products_description_1');

有没有一种方法使jQuery选择类似$('#some [2]').function ...的东西??

Is there a way to make jQuery to select something like this $('#some[2]').function... ?

如果没有，如果还有另一种方法可以更改ID值，则可以，因为我可以像往常一样工作，然后将其更改回[]，以便php识别该字段

If not, If there's another way I can change the ID value then it's ok because I can work as usually and then change it back to the [ ] for the php to recognize that field

是的，我知道，我可以按照类的其他方式选择文本区域，但是由于te页面中有很多texareas，因此我需要一个唯一的名称，这将需要编辑我不需要的osCommerce脚本.我打算将我的JS贡献给oscommerce社区，并且让另一个人添加.js很容易，但是如果他们必须编辑php文件以使javascript正常工作，对于新手来说可能太吓人，或者对于某人来说可能是不可能的已经对其进行了编辑.

Yes, I know, I can select the textarea in another way like by class, but as there are many texareas in te page, I need a unique name and that would requiere editing osCommerce script which I don't want. I plan to contribute my JS to the oscommerce community and for another person to just add a .js is easy, but if they have to edit a php file for the javascript to work it could be either too scary for a newbie or impossible for somebody that already edited it.

非常感谢

推荐答案

尝试一下:

$('#product_description\\[1\\]')

请注意，尽管这可能可行，但括号字符不适用于HTML5之前的ID(尽管可以在类中使用).

Note that while this may work, the bracket characters are not valid for use in IDs prior to HTML5 (although they're fine for use in classes).
