Whats a good way to select elements by their name using wildcards?
The website has element names in the form of <a_1786439></a_1786439> which are likely auto-generated. This is doable by xpath, but is it doable using css selectors or jquery selectors which are faster?
This is clearly terrible-coding, but the website is not mine, and I'm writing a userscript for it.
回答1:
This doesn't exist in CSS3, as the spec's section on type selectors only includes names and wildcards, but no combinations of them.
回答2:
It's possible to create custom elements using the HTML DOM createElement method like this:
document.createElement('Funny_Element');
In the website code you are dealing with, they have created a custom element, or maybe extend the a element, but they didn't choose a significant name! a_1786439??? which is, I think, really bad.
Using CSS selectors or jQuery selectors depends essentially on what you want to do. Suppose you have to access children elements of a specific node, then jquery selectors would be more appropriate.
Hope it's useful!
