View Full Version : [JQuery]Extending the height of a js controlled div containers...

12-17-2009, 11:57 AM
Hello peoples,

Having a bit of trouble with some old code that i'm wanting to re-use. I currently have the need to create a bio that can be clicked to show and hide the content placed inside. All works so far, but I can't figure out how to increase the height of the opened containers...seems it has a set height somewhere and my content is hidden from view.

below is the appropriate code...

// Basic Element Animator
// by Vic Phillips http://www.vicsjavascripts.org.uk

// To progressively change the Left, Top, Width, Height or Opacity of an element over a specified period of time.
// With three types of progression 'sin' and 'cos' and liner.

// **** Application Notes

// **** The HTML Code
// when moving an element the inline or class rule style position of the element should be assigned as
// 'position:relative;' or 'position:absolute;'.
// The element would normally be assigned a unique ID name.

// **** Executing the Effect(Script)
// The effect is executed by an event call to function 'zxcBAnimator('width#',document.getElementById('tst'),10,800,5000,[10,800],'sin');'
// where:
// parameter 0 = the mode(see Note 2). (string)
// parameter 1 = the unique ID name or element object. (string or element object)
// parameter 2 = the start position of the effect. (digits, for opacity minimum 0, maximum 100)
// parameter 3 = the finish position of the effect. (digits, for opacity minimum 0, maximum 100)
// parameter 4 = (optional) period of time between the start and finish of the effect in milliseconds. (digits or defaults to 2000 milliSeconds)
// parameter 5 = (optional) to scale the effect time on a secified minimum/maximum. (array, see Note 5)
// field 0 the minimum. (digits)
// field 1 the maximum. (digits)
// parameter 6 = (optional) the type of progression, 'sin', 'cos' or 'liner'. (string, default = 'liner')
// 'sin' progression starts fast and ends slow.
// 'cos' progression starts slow and ends fast.
// Note 1: The default units(excepting opacity) are 'px'.
// Note 2: Examples modes: 'left', 'top', 'width', 'height', 'opacity.
// For hyphenated modes, the first character after the hyphen must be upper case, all others lower case.
// Note 3: To 'toggle' the effect include '#' in parameter 0.
// The first call will set the toggle parameters.
// Subsequent calls with '#' in parameter 0 and the same start and finish parameters will 'toggle' the effect.
// Note 4: The function may be re-executed with a different set of parameters (start/finish time or period)
// whenever required, say from an onclick/mouseover/out event.
// The period parameter will be retained unless re-specified.
// Note 5: parameter 5 is of particular use when re-calling the effect
// in mid travel to retain an constant rate of progression.

// **** General
// All variable, function etc. names are prefixed with 'zxc' to minimise conflicts with other JavaScripts.
// These characters may be changed to characters of choice using global find and replace.
// The Functional Code(about 2.06K) is best as an External JavaScript.
// Tested with IE7 and Mozilla FireFox on a PC.

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.


If you just make a copy of the above code and then view it in your browser, you'll see that when clicked to open, that only upto "...from a Lorem Ipsum passage, and going..." is shown, the content there after is hidden from view, is there anyway to set a height or maybe make the height of the content reliant on the content placed inside?

cheers in advance for any help and once again thanks to Vic Phillips for his nifty script.

This is a JQuery related problem, thus I moved this thread into the proper JavaScript Frameworks Forum.

The height that the container will animate to is passed into the function call in the onclick. See where it says:


change that to read:


and your container will open to 200px, instead of 100px height.

ps. Kor, it's got a call to the jQuery file, but it makes no use of it. This would be better placed back in the main JS forum.
