(go, record with) 3 Ways to initialize jquery page loading

JQuery page Load initialization method There are 3 kinds of pages in the load when the script will be executed, there should be no difference, mainly look at the habit, I think the second method is the best, relatively concise.

The first type:

[JavaScript]View PlainCopy

1. $ (document). Ready (function () {
2. Alert ("the first method.   ");
3. });

The second type:

[JavaScript]View PlainCopy

1. $ (function () {
2. Alert ("the second method.  ");
3. });

The third type:

[JavaScript]View PlainCopy

1. JQuery (function ($) {
2. Alert ("the third method.  ");
3. });

PS; without jquery, in the method of page initialization,

1. Write OnLoad inside the body

2. Write in the script

[JavaScript]View PlainCopy

1. window.onload=function () {
2. //What to initialize
3. }

Since jquery uses the $ notation to conflict with some components, such as DWR, in order to solve this problem, you can use the

[JavaScript]View PlainCopy

1. var j = jquery.noconflict ();

This replaces the $ with "J".
