如何获取jQuery选择器的文本表达式? [英] How do I get a jQuery selector's expression as text?

问题描述

我有一个jQuery选择器，它具有链式功能.

I have a jQuery selector, which has a chained function.

在函数中，我想访问表示选择器表达式的TEXT.

Inside the function I want to get access to the TEXT representing the expression for the selector.

$("cat dog").function() {

    // how do I get access to the "cat dog" string from inside THIS function ?
};

在此代码示例中，我已经过度简化了实际要做的事情.我正在编写一个插件，我需要访问为其创建包装集的选择器.显然，在此特定示例中，由于我编写了猫狗"，因此我可以使用它.因此，只需将其想象在插件中即可.

I've over simplified in this code sample what I actually want to do. I'm writing a plug-in and I need access to the selector for which the wrapped set has been created. Obviously in this particular example I have access to "cat dog" becasue i wrote it. So just picture this being in a plugin.

为此，Google会遇到一些麻烦.

Its a little tricky to google for this.

编辑:很遗憾，现在不推荐使用选择器"属性. http://jquery.com/upgrade-guide/1.9/#selector-property-on-jquery-objects

edit: the 'selector' property is unfortunately now deprecated. http://jquery.com/upgrade-guide/1.9/#selector-property-on-jquery-objects

推荐答案

jQuery对象中有一个'selector'属性，但是我不确定它是否始终可用.

There is a 'selector' attribute in the jQuery object, but I'm not sure it's always available.
