jquery dynamic id

Question

i use such code to access item

function f(id){

$(\"#\"+id).val(); // with analogy $(\"#id item\")
}

is it correct? is any other methods?<

Answer 1

From the jQuery API website:

.val() Returns: String, Array

Description: Get the current value of the first element in the set of matched elements.

What It's not clear to me when you say

// with analogy $("#id item")

is if you want to have ONLY one child item of the one that is identifiedby #id or if you need the item that is identified by item#id.

Your code is perfect if you are passing a string like "hello" inside your code and you want to get the DOM element with ID of #hello.
