jQuery "Does not have attribute" selector?
提问by H O
I can find a div that has an attribute like so:
我可以找到一个具有如下属性的 div：
$('.funding-plan-container[data-timestamp]')
But if I try to find a div that does not have that attribute, I get an error - my code is:
但是，如果我尝试查找没有该属性的 div，则会出现错误 - 我的代码是：
$('.funding-plan-container[!data-timestamp]')
Is there a "does not have attribute" selector in jQuery?
jQuery 中是否有“没有属性”选择器？
For reference, the use case here is that any div that does not have a timestamp attribute was not added dynamically, and hence is useful.
作为参考，这里的用例是任何没有时间戳属性的 div 都不是动态添加的，因此很有用。
Thanks!
谢谢！

Use the :not()selector.
使用:not()选择器。
$('.funding-plan-container:not([data-timestamp])')
This, by the way, is a valid Selectors APIselector, so it isn't specific to jQuery. It'll work with querySelectorAll()and in your CSS (given browser support).
顺便说一下，这是一个有效的Selectors API选择器，因此它不是特定于 jQuery 的。它将与querySelectorAll()您的 CSS一起使用并在您的 CSS 中使用（提供浏览器支持）。

Try it with the :not()pseudo-class selector: http://api.jquery.com/not-selector/
尝试使用:not()伪类选择器：http: //api.jquery.com/not-selector/
$('.funding-plan-container:not([data-timestamp])')
