This article mainly explains "what are the matters needing attention in jQuery.get". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn what matters needing attention in jQuery.get.

Additional Notes: (other precautions:)

Due to browser security restrictions, most "Ajax" requirements follow a policy of the same origin; that is, data cannot be correctly received from different domains, subdomains, or protocols.

If a jQuery.get () request returns an error code, it quietly fails unless the script calls the global .ajaxError () method. In jQuery 1.5, the .error () method of the jqXHR object returned through jQuery.get () can also be used for error handling.

Requests in the form of Script and JSONP are not subject to the same origin policy.

Example:

Example: request the test.php page, but ignore the return result.

$.get ("test.php")

Example: request the test.php page and send the url parameter (although the returned result is still ignored).

Get ("test.php", {name: "John", time: "2pm"})

Example: passes an array of data parameters to the server (although the returned results are still ignored).

$.get ("test.php", {'choices []': ["Jon", "Susan"]})

Example: the result of the data requested by Alert from test.php (HTML or XML, depending on the result returned).

$.get ("test.php", function (data) {

Alert ("Data Loaded:" + data)

})

Example: Alert requests from test.cgi and sends the data result of the url parameter (HTML or XML, depending on the returned result).

$.get ("test.cgi", {name: "John", time: "2pm"}

Function (data) {

Alert ("Data Loaded:" + data)

})

Example: get the content in JSON format returned by the test.php page () and add it to the page.

$.get ("test.php"

Function (data) {

$('body') .append ("Name:" + data.name) / / John

.append ("Time:" + data.time); / / 2pm

}, "json")
