AJAXRequest is a lightweight AJAX application development framework, which is compatible with Firefox, IE, Opera and Safari. It can easily perform some operations that are often used in AJAX, so as to simplify the development steps and reduce the amount of repetitive code writing.

If you find a problem during use, or if you have any good comments and suggestions, you can email me at vipxjw [at] 163 [dot] com.

Update description

1. Change the return value of the update method to update request ID

In this version, the update method no longer returns a timer ID, that is, you can no longer use the return value of the update method as a parameter to use the clearInterval method to stop the update, but instead use the stopupdate method inside AJAXRequest to stop the update.

In addition, not only unlimited updates will return update ID, but limited updates will also return update ID, that is, if you only update a specified number of times, you can also use the stopupdate method to stop updates before the specified number of updates is reached.

Example (JavaScript):

Program code: [copy code to clipboard]

The copy code is as follows:

/ / code sample by xujiwei

/ / site: http://www.xujiwei.cn/

Var ajax = new AJAXRequest ()

Var u

/ / start an unlimited number of times to update the object updateObj from test.asp at an interval of 1 second

Function start () {

U = ajax.update ("updateObj", "test.asp", 1000)

}

/ / stop updating

Function stop () {

Ajax.stopupdate (u)

}

two。 Modify the form validation property onsubmit of the postf method to onvalidate

If you use onsubmit for form validation, it may conflict with some applications, so change the form validation property to onvalidate, for example (HTML):

The copy code is as follows:

/ / code sample by xujiwei

/ / site: http://www.xujiwei.cn/

3. Modify the parameter of postf method to post (form, [callback])

This modification limits the parameters of the postf method to form objects and callback functions, that is, action and method must be specified in the form tag, for example (HTML):

Program code:

The copy code is as follows:

/ / code sample by xujiwei

/ / site: http://www.xujiwei.cn/

/ / the action and method attributes of the form tag must be specified
