If you are work on Codeigniter application and you require to get client ip address then you can get easy. you don't need to use $_SERVER variable like native PHP, but Codeigniter provide $this->input. you can fetch easy using following example:

Most of the time we require to check specific element is exists or not in javascript. but jquery provide length() method that can help to check element is exists or not. If you are new and want to do this then see bellow example:
<strong class="example">Example:</strong>
<pre class="prettyprint lang-js">
<script type="text/javascript">
$(document).ready(function(){
if ($('.image').length) {
console.log('yes, Image class is exists.');
} else {
console.log('sorry, Image class is not exists.');
}
});
</script>
</pre>

If you want to get Query string value then you can get using Request Facade OR Input Facade in larave 5. But if you was working native PHP then we can get $_GET method. In following example you can easily get parameter value.
<strong class="example">URL Example:</strong>
<pre>http://text.com/wall?id=23&name=hdtopi</pre>
In above query string, you want to get query string value for example id and name. you can get through bellow example.

<pre>Route::get('wall', 'WallController@wall');</pre>
<strong class="example">Controller Example:</strong>
