Uncaught ReferenceError: $ is not defined in a jquery function

Question

I had been getting this message when I use a JavaScript function for the onchange event of a select option.

The function is:

<script type="text/javasript" src="jquery.min.js"></script>
<script type="text/javascript">
function desigchanged()
{
    
    $.get('jqueryphp.php?desig=wr',update);
}
function update(res)
{
    $('#inpt4').html(res);
}
</script>


<select id="inpt3" name ="designatn" onChange="desigchanged();">
            <option value="pm" selected>project manager</option>
            <option value="wr">worker</option>
            </select><BR><BR>
            <label><font id="fnm">Gender</font></label>
            <label><font id="fnm3">Male</font></label>
            <input name="gender" type="radio" id="inpt11" value="Male" />
            <label><font id="fnm4">Female</font></label>
            <input name="gender" type="radio" id="inpt22" value="Female" /><BR><BR>
            <label><font id="fnm">Works Under</font></label>
            <select name="wrkundr" id="inpt4">
            </select>

The jQuery file is included properly. Please someone help me.

I suspect it's because of the typo:

type="text/javasript"

Note the missing "c" in "script". Browsers won't execute a script tag if its type attribute hasn't been defined correctly.

It's all the browsers according to my tests - if the type is defined but not correct, it won't be executed. This is good because you can place templates in `text/html` or whatever. Here's my test http://jsfiddle.net/s5rnv/ – Esailija Jul 22 '12 at 09:20
@Esailija: Thanks; I usually omit it altogether. – pimvdb Jul 22 '12 at 09:21

Edit:

But you may also be facing this problem (absolute/relative paths).

And

You also have a typo for javascript

Original:

have you done this

You should put the references to the jquery scripts first.

Or

This?

Maybe you are calling the ready function before the JQuery Javascript is included?

As can be seen in his snippet, he's including jQuery at the top and he's not using `ready`. – pimvdb Jul 22 '12 at 09:10
@pimvdb yeh, I just wanted to make sure that its the same way he is executing too. as some ppl cut/paste codes and make it cleaner here to make it look good :P ... btw I edited my post too – footy Jul 22 '12 at 09:17
