The aim of this example is to show you how to use the jQuery .get() method.
The jQuery .get() method is used to load data from the server using a HTTP GET request.
The signature of this method is like jQuery.get(url [,data][,success][,dataType ]) where only the url is mandatory.
Some methods as .done(), .fail(), and .always() can be chained to this method. These methods are executed during ajax execution.
Let’s look at some examples. To download the jQuery library, click here.
1. HTML
First of all you need to create a simple html document.
jQueryGetExample.html
<!DOCTYPE html> <html> <head> <title>jQuery Get Example</title> <script src="jquery-2.1.4.min.js"></script> </head> <body> </body> </html>
2. jQuery Get examples
2.1 Loading data from server
Let’s add the following simple html code.
<div id="container" style="height:40px;width:150px;border:1px solid #eee"></div><br/> <a href="javascript:retrun 0;" onclick="showUserInfo()">Show User Info</a>
As you can notice in the following example, the jQuery .get() method is used to send a request to the server and pass the returned data to the success function (The second argument).
<script type="text/javascript">
function showUserInfo(){
$.get( "data.txt", function(data) {
jQuery("#container").html(data);
});
}
</script>
data.txt
Data from server !
The result in the browser would be:
2.2 Loading json by jQuery get method
Let’s add the following simple html code.
<div id="container" style="height:100px;width:200px;border:1px solid #eee"></div><br/> <a href="javascript:retrun 0;" onclick="loadjson()">Show User Info</a>
In this example, we need to get json formatted data for that we passed the datatype parameter as json.
<script type="text/javascript">
function loadjson(){
$.get("personaldata1.json", function( data ) {
$.each( data, function( key, val ) {
$("<div>" + key + " = " + val + "</div>").appendTo( "#container" );
});
},"json");
}
</script>
personaldata1.json
{
"firstname":"saeb",
"lastname":"nar",
"age":30
}
The result in the browser would be:
