how to include a external js function as a internal js function?

i have external js file for circular progress bar.i dont want to have my js file as a external file.i want to have this function also as a internal js function.when i tried including this function i got function is not defined error..
below is the code..
Internal js script...
<script>
( function( $ ){
$( '#circle' ).progressCircle();
$( '#submit' ).click( function() {
$( '#circle' ).progressCircle({
nPercent : 100,
showPercentText : true,
thickness : 4,
circleSize : 50
});
})
})( jQuery );
</script>
My external js file...
( function( $ ){

options );

var offset = ( 1 - thicknessConstant * settings.thickness * 2 ) +
'em';

if ( settings.nPercent == 0 ) {
circleSlice.hide();
} else {
resetCircle();
transformCircle( nRadians, circleDiv );
}
setBorderThickness();
updatePercentage();
setCircleSize();
function computePercent () {
settings.nPercent > 100 || settings.nPercent < 0 ? settings.nPercent

}
}
function setCircleSize ( ) {

how to integrate this external js with internal js script and make it work?

Scripts are run linearly. Therefore, if you want to access code in an external script, you'll need to reference it before your internal script.
<script src="external script path"></script>
<script>
your internal script with access to external script

Cslider.js How to random slide order

I have Cslider.js and want the first slide to come up the same each time, however the slides after that I would want them to come up in random order, I have looked on Stackflow, and although there is some similar, I can not get it to work for me, any help greatly appreciated, here is what I have

JQuery .on() function alternative for JQuery version 1.61

I came across a situation where I need to adapt a script that works with JQuery 1.7.1 to work with JQuery 1.6.1, basically I need to convert the .on() to something that works with JQuery 1.6.1

Since it doesn't look like there's any event delegation happening, you should be able to directly replace .on with .bind.

How can I add a css element change to an onlick event in this jquery lib?

I've got this awesome slideshow library working just fine on my site (yoinked from codrops), but since I'm shifting between different pieces of information, I want to really call out the difference by adding a CSS change so that the background color matches the color of the content in the slide. Now, this is a library, so i figure I need to add the $('body').css call into it, and not my html doc. I'm including the code below, with a note marking where I think it's supposed to go. I'm jsut not sure what the exact phrasing would be since I've never worked inside a lib before. Any suggestions would be welcome!

Answered my own question with a little digging.
_navigate : function( direction ) {
// do nothing if the list is currently moving
if( this.isAnimating ) {
return false;
}
this.isAnimating = true;
// update old and current values
this.old = this.current;
if( direction === 'next' && this.current < this.itemsCount - 1 ) {
++this.current;
}
else if( direction === 'previous' && this.current > 0 ) {
--this.current;
}
console.log(this.current);
if(this.current == 0)
{
$('body').css('background', '#FF6A00');
}else if(this.current == 1)
{
$('body').css('background', '#595C5A');
}else if(this.current == 2)
{
$('body').css('background', '#000000');
}
// slide //AROUND HERE?
this._slide();
},

Call javascript class method from another method

I have problem calling one method from another method in a Javascript class.
Here is the code
function Spinner( max_value , min_value , div_id ){
var MAX_VALUE = 25;
var MIN_VALUE = -25;
var DEFAULT_VALUE = 0;
this.maxValue = max_value;
this.minValue = min_value;
this.divId = div_id;
this.spinnerControl; //spinner control object that is populated in getSpinner() method.
this.rotateSpinner = function (spinnerTextBoxId,up) {
document.getElementById(spinnerTextBoxId).value = up ? parseInt(document
.getElementById(spinnerTextBoxId).value) + 1 : parseInt(document
.getElementById(spinnerTextBoxId).value) - 1;
};
this.getSpinner = function( ){
spinnerControl = $('<input type="text"></input>')
.attr('id' , 'spinner')
.attr('val' , DEFAULT_VALUE)
.add( $('<ul></ul>')
.addClass("spinner")
.append(
$('<li></li>')
.append($('<input type="button"></input>')
.attr({
id : 'upButton',
value : '▲'
}).appendTo( $('<li></li>') )
)
).append( $('<li></li>')
.append($('<input type="button"></input>')
.attr({
id : 'downButton',
value : '▼'
}).appendTo( $('<li></li>') )
)
)
);
var timeoutId = 0;
$('#upButton' , spinnerControl).mousedown(function() {
console.log('mouse down');
timeoutId = setInterval(this.rotateSpinner('spinner' , true ) , 200);
}).bind('mouseup mouseleave', function() {
console.log('mouse left');
//clearTimeout(timeoutId);
});
// $('#downButton').mousedown(function() {
// alert('herer');
// //timeoutId = setInterval("rotateSpinner('spinner' , false ) ", 200);
// }).bind('mouseup mouseleave', function() {
// clearTimeout(timeoutId);
// });
return spinnerControl;
};
//class END
}
In this js file ,the error shows up in firebug : "Reference error : rotateSpinner" is not defined.
Why is it appearing ?

this is referring the DOM-element, which in this case is the '#upButton'. If you add a variable that points to the class, you can then refer to this one instead of this when defining functions within the method.
function Spinner( max_value , min_value , div_id ){
var MAX_VALUE = 25;
var MIN_VALUE = -25;
var DEFAULT_VALUE = 0;
this.maxValue = max_value;
this.minValue = min_value;
this.divId = div_id;
this.spinnerControl; //spinner control object that is populated in getSpinner() method.
this.rotateSpinner = function (spinnerTextBoxId,up) {
document.getElementById(spinnerTextBoxId).value = up ? parseInt(document
.getElementById(spinnerTextBoxId).value) + 1 : parseInt(document
.getElementById(spinnerTextBoxId).value) - 1;
};
this.getSpinner = function( ){
var self = this;
spinnerControl = $('<input type="text"></input>')
.attr('id' , 'spinner')
.attr('val' , DEFAULT_VALUE)
.add( $('<ul></ul>')
.addClass("spinner")
.append(
$('<li></li>')
.append($('<input type="button"></input>')
.attr({
id : 'upButton',
value : '▲'
}).appendTo( $('<li></li>') )
)
).append( $('<li></li>')
.append($('<input type="button"></input>')
.attr({
id : 'downButton',
value : '▼'
}).appendTo( $('<li></li>') )
)
)
);
var timeoutId = 0;
$('#upButton' , spinnerControl).mousedown(function() {
console.log('mouse down');
timeoutId = setInterval(self.rotateSpinner('spinner' , true ) , 200);
}).bind('mouseup mouseleave', function() {
console.log('mouse left');
//clearTimeout(timeoutId);
});
// $('#downButton').mousedown(function() {
// alert('herer');
// //timeoutId = setInterval("rotateSpinner('spinner' , false ) ", 200);
// }).bind('mouseup mouseleave', function() {
// clearTimeout(timeoutId);
// });
return spinnerControl;
};
//class END
}

Depends on how you call this function.
If you call it like this:
Spinner().rotateSpinner(arg1, arg2);
You would the error you mentioned.
The right usage is:
new Spinner().rotateSpinner(arg1, arg2);
It's better you learn more about variable scope of javascript.
