Native AJAX request

##AJAX request in JQuery

$.ajax method

data represents the data format sent to the server There are two types: One: name=value&name=value Two: {key:value}

dataType The response data type. Commonly used data types are: text Represents plain text xml Represents xml data json Represents json object

$.get method and $.post method

url requested url address
