jQuery Selectors: Select element with specific class and 'title' attribute
提问by MegaMatt
This should be an easy one, but I can't find a good example anywhere. I'm trying to select a particular element on my page that has a class of 'statuslight' and a title attribute of one of three options. The option (it will depend) is stored in a variable called 'currentStatus'. I've seen some examples, and I'm guessing this is the right track, but I need to know for sure:
这应该很简单，但我在任何地方都找不到好的例子。我试图在我的页面上选择一个特定元素，该元素具有“statuslight”类和三个选项之一的标题属性。该选项（取决于）存储在一个名为“currentStatus”的变量中。我看过一些例子，我猜这是正确的轨道，但我需要确定：
$(".statuslight[title]='" + currentStatus + "'");

Very close:
很接近：
$(".statuslight[title='" + currentStatus + "']");
Supposing your currentStatusis an array, you could get all statuslightelements with a title that contains any of the currentStatusvalues with:
假设您currentStatus是一个数组，您可以获得statuslight标题包含以下任何currentStatus值的所有元素：
$(".statuslight[title='" + currentStatus[0] + "'], .statuslight[title='" + currentStatus[1] + "'], .statuslight[title='" + currentStatus[2] + "']");
Alternatively, if your title has multiple statuses (title="status1 status2 status3"), and currentStatusis only one item you would use this selector:
或者，如果您的标题有多个状态 ( title="status1 status2 status3")，并且currentStatus只有一个项目，您将使用此选择器：
$(".statuslight[title~='" + currentStatus + "']");
