您可能会使用eval()，但是您正在做的事情似乎是一个非常糟糕的主意:

You would use eval() but what you are doing seems like a really bad idea:

var x = $('#id').attr('jq');
eval(x);

这很不好的原因是您没有将功能与结构分开. HTML旨在描述结构，而不是交互性和功能.

The reason this is bad, is you are not separating function from structure. HTML is meant to describe structure, not interactivity and function.

JavaScript旨在提供这种交互和增强功能，而不是结构.像这样使用jQuery内联违反了这种分隔.只是值得深思的……

JavaScript is meant to provide that interaction and enhancement, but not structure. Using the jQuery inline like that is a violation of that separation. Just food for thought...
