Look for script on mouse over image gets bigger

**mikster** · 07-30-2011, 03:54 AM

Hi,

Can someone tell me how they are doing this on this page http://imgur.com/gallery/ffs1v where the image is rescaled to fit the layout and once I click it the large full scale picture pop up. Please point me in the right direction or suggest a script that does the same. Thanks in advance.

// Animate (24-June-2011)
// 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 the ability to scale the effect time on specified minimum/maximum values
// and with three types of progression 'sin' and 'cos' and liner.

// The functional code size is 1.39K

// **** Application Notes

// **** The HTML Code
//
// when moving an element the inline or class rule style position of the element should be assigned as

//
// The element would normally be assigned a unique ID name.
//

// **** Initialising the Script.
//
// The script is initialised by assigning an instance of the script to a variable.
// e.g A = new zxcAnimate('left','id1')
// where:
//  A           = a global variable                                                               (variable)

// **** Executing the Effect
//
// The effect is executed by an event call to function 'A.animate(10,800 ,5000,[10,800]);'
// where:
//  A           = the global referencing the script instance.                                 (variable)
//  parameter 0 = the start value.                                                            (digits, for opacity minimum 0, maximum 100)
//  parameter 1 = the finish value.                                                           (digits, for opacity minimum 0, maximum 100)
//  parameter 2 =  period of time between the start and finish of the effect in milliseconds. (digits or defaults to previous or 0(on first call) milliSeconds)
//  parameter 3 = (optional) to scale the effect time on a specified minimum/maximum.         (array, see Note 3)
//                 field 0 the minimum value. (digits)
//                 field 1 the maximum value. (digits)

//                 'sin' progression starts fast and ends slow.
//                 'cos' progression starts slow and ends fast.
//
//  Note 1:  Examples modes: 'left', 'top', 'width', 'height', 'opacity.
//  Note 2:  The default units(excepting opacity) are 'px'.
//           For hyphenated modes, the first character after the hyphen must be upper case, all others lower case.
//  Note 3:  The scale is of particular use when re-calling the effect
//           in mid progression to retain an constant rate of progression.
//  Note 4:  The current effect value is recorded in A.data[0].
//  Note 5:  A function may be called on completion of the effect by assigning the function
//           to the animator intance property .Complete.
//           e.g. [instance].Complete=function(){ alert(this.data[0]); };

Wow thanks alot just what I need. I'm not that good with javascript but I managed to integrate the code into my site to get it functioning properly. The only thing I couldn't figure out is where in the code do I modify to set the magnification level. Basically I have 2 copies of every image I upload. 1 copy is the small version and the other one is the bigger version. The code that you pasted has a default width set to 250px whereas my default width on my site is 620. So what happens is that when i change 250 to 620 and click on it to magnify the pic....the magnification becomes super super big. Do you know where in the code I can modify to downsize the magnification?

Thanks again.

// **** Executing the Effect
//
// The effect is executed by an event call to function 'A.animate(10,800 ,5000,[10,800]);'
// where:
//  A           = the global referencing the script instance.                                 (variable)
//  parameter 0 = the start value.                                                            (digits, for opacity minimum 0, maximum 100)
//  parameter 1 = the finish value.                                                           (digits, for opacity minimum 0, maximum 100)
//  parameter 2 =  period of time between the start and finish of the effect in milliseconds. (digits or defaults to previous or 0(on first call) milliSeconds)
//  parameter 3 = (optional) to scale the effect time on a specified minimum/maximum.         (array, see Note 3)
//                 field 0 the minimum value. (digits)
//                 field 1 the maximum value. (digits)
//  parameter 3 = (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:  Examples modes: 'left', 'top', 'width', 'height', 'opacity.
//  Note 2:  The default units(excepting opacity) are 'px'.
//           For hyphenated modes, the first character after the hyphen must be upper case, all others lower case.
//  Note 3:  The scale is of particular use when re-calling the effect
//           in mid progression to retain an constant rate of progression.
//  Note 4:  The current effect value is recorded in A.data[0].
//  Note 5:  A function may be called on completion of the effect by assigning the function
//           to the animator intance property .Complete.
//           e.g. [instance].Complete=function(){ alert(this.data[0]); };
//

the magnifycation can be set in the image class name
or by modificating the default of 3 in the line I have marked in red
