jquery $("<li />")

Wha开发者_StackOverflow社区t does:

$("<li />")

mean in jquery?

---

it's like document.createElement('li');

---

Create's a new (but empty) li element, similar to document.createElement("li");. Try doing this:

alert($("<li />")[0]);

Essentially, alone it does not do much. To add it to an existing element you could do something like:

$("<li />").appendTo("body");
$("<li />").appendTo("#elementId");

---

It will create a li element, similar to https://developer.mozilla.org/en/DOM/document.createElement

---

Creates DOM elements (in this case LI) on the fly from the provided string of raw HTML.

---

By itself nothing but if you add

$('<li />').appendTo('body'); 

It will create an li at the end of the body element of your HTML
