get method in javascript code example

Example 1: GET req with js

function httpGet(theUrl) {
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", theUrl, false ); // false for synchronous request
    xmlHttp.send( null );
    return xmlHttp.responseText;
}

Example 2: jquery get request

jQuery get() Method
The jQuery get() method sends asynchronous http GET request to the server and retrieves the data.

Syntax:
$.get(url, [data],[callback]);
Parameters Description:

url: request url from which you want to retrieve the data
data: data to be sent to the server with the request as a query string
callback: function to be executed when request succeeds
The following example shows how to retrieve data from a text file.

Example: jQuery get() Method
$.get('/data.txt',  // url
      function (data, textStatus, jqXHR) {  // success callback
          alert('status: ' + textStatus + ', data:' + data);
    });
In the above example, first parameter is a url from which we want to retrieve the data. Here, we want to retrieve data from a txt file located at mydomain.com/data.txt. Please note that you don't need to give base address.

Example 3: $_GET data using javascript

function $_GET(q,s) {
    s = (s) ? s : window.location.search;
    var re = new RegExp('&'+q+'=([^&]*)','i');
    return (s=s.replace(/^\?/,'&').match(re)) ?s=s[1] :s='';
}

console.log($_GET("myvariable"));
