是否有任何功能可以帮助转义jquery的选择器中包含的所有元字符? [英] is there any function which can help escape all meta-characters contained in jquery‘s selector？

问题描述

直接从jQuery文档:

Straight from jquery docs：

如果您希望使用任何元字符(例如!"#$%&'()*+,./:;<=>?@[\]^&a{|}~)作为名称的文字部分)，则必须使用两个反斜杠对字符进行转义:\.例​​如，如果您的元素具有，则可以使用选择器$("#foo\\.bar").

If you wish to use any of the meta-characters (such as !"#$%&'()*+,./:;<=>?@[\]^&a{|}~) as a literal part of a name, you must escape the character with two backslashes: \. For example, if you have an element with id="foo.bar", you can use the selector $("#foo\\.bar").

我想知道有什么功能可以帮助我摆脱那些元字符吗?

I want to know is there any function can help me to escape those meta-charcters？

推荐答案

查看

Check out this video about jQuery bugs, the author has a function he wrote that uses regexs to properly escape all jQuery selectors @52:18. Side note: the video is great, every developer using jQuery should watch it.

为后代而转录:

String.prototype.escapeSelector = function () {
    return this.replace(
        /([$%&()*+,./:;<=>?@\[\\\]^\{|}~])/g,
        '\\$1'
    );
};

您将这样使用:

$('#' + 'foo.bar'.escapeSelector());
