$(this[id^= "PostTypes"])

But nothing want works.

Answer 1

Try,

 $('[id^= "PostTypes"]', this); // if you want to find the elements that are descendants of this.

Or if you want to check if the current element is a match then you can use .is(selector) :

$(this).is('[id^= "PostTypes"]'); //Check if this element is havind the id startswith PostTypes.

Example:

if($(this).is('[id^= "PostTypes"]')){
   //Current element starts with id PostTypes, do something with it.
}

Answer 2

使用filter（）

$(this).filter('[id^= "PostTypes"]')

Answer 3

我相信你想要：

$('[id^="PostTypes"]', this)
