Javascript Error in Ubuntu Uncaught ReferenceError: $ is not defined

I am working with jquery, javascript, php in Ubuntu Platform. In the page i am sending an ajax request through jquery to php file and getting response text. This program was running successfully in windows-(wamp) platform and online. But in Ubuntu i am getting javascript error. The code follows...

    url = "index.php";

    $.get(url,{
            'action': 'Loan',
        },
        function(responseText){     
            alert(responseText);
        },
        "html"
    );

In Ubuntu i am getting this error, "Uncaught ReferenceError: $ is not defined". This error was showing at $.get line. In the script tag i included jquery library file too. I dont know why this is error is coming. Please solve my issue. Thanks in Advance.

Solution

  • $ is not defined on JQuery means the JQuery library is not loaded.

    It can happen due to many reasons such as,

    1. Path on Windows is not same in Ubuntu.
    2. In windows file names are case insensitive but in Linux its case sensitive.

    I suggest you use JQuery from google.

    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js">
</script>
