jQuery:如何在此处选择具有特定类的元素? [英] jQuery:How to select elements with particular class here?

问题描述

HTML像这样:

<span class="someClass position1" >span1</span>
<span class="someClass" >span2</span>
<span class="someClass" >span3</span>
<span class="someClass position2" >span4</span>
<span class="someClass" >span5</span>
<span class="someClass position4" >span6</span>
<span class="someClass position10" >span7</span>
<span class="someClass" >span8</span>
<span class="someClass position12" >span9</span>

现在，使用jQuery，如何仅更改具有类position + SomeINTEGER 的那些元素的backgroundColor?

Now, using jQuery, how will I change the backgroundColor of only those elements which have the class position+SomeINTEGER?

我想选择所有类别为poistion + TheRespectiveInteger

I want to select all the elements with the class poistion+TheRespectiveInteger

推荐答案

我假设您要更改 all 元素的背景，这些元素具有与该模式匹配的类-不仅仅是针对一种模式特定号码.

I'm assuming you want to change the background of all the elements that have a class matching that pattern - not just for one particular number.

通过将class视为另一个属性并对值进行部分匹配，可能有一种 hacky 方式.

There is probably a hacky way to do this by treating class as just another attribute and doing a partial match against the value.

但是，更好的解决方案是添加另一个可以选择的类.也许在添加positionX类的同时还添加了positioned类.

However a better solution is to add another class that you can select on. Perhaps have whatever is adding the positionX classes also add a positioned class at the same time.
