multiSteps multi-step sliding switching plug-in based on Jquery_jquery

Illustration: Viewing in a browser that supports Html5 will have a better experience
Among them, versions below IE9 use a filter to simulate a shadow. Delete the content here and the operation will be smoother under IE (at least my old machine runs smoother) . )
Illustration of the first step:
The startup function needs to return a value. You can do whatever you want in this startup function, but you must return a value after you have done the bad thing.
You have to Stop and wait for the processing result, then return false and cannot continue execution. If
is not found, leave here quickly, return true, and continue to the next step!

Illustration of the second step: The prompt that pops up is the callback function after the first step is executed

The callback function has no return value. In fact, when the callback function is executed, it is separated from the plug-in. You can do whatever you want here!

The third step is completed:

Another page in the Demo demonstrates more layer calls.
Plug-in description:
Calling method $('obj').multiSteps({options});
Supports callback function and startup function (before starting sliding)
Parameter list that can be set:

Copy code The code is as follows:

　　{ // Global defaults
showOn: 'click' , // 'click' or 'mouseOn'
showAnim: 'leftRight', // Temporarily defined to wait for expansion, not used
slidefor: 'next',
showSpeed: 1000, //Sliding speed, the longer Smaller and faster
beforeSlide: null, //Function executed before sliding
callback: null //callback
};

You can call each button individually Call:

Copy code The code is as follows:

$("#step_one").multiSteps( {beforeSlide:_beforeSlide,callback:_callback});
$(".prevStep").multiSteps({slidefor:'prev'});
$("#step_two").multiSteps({callback:function (){alert("Second step execution completed")}});

can also be called in this way: $(".classs:not(.lastStep)").multiSteps( ; This problem)
The two steps before (and after) the current step will appear in the field of view after the page is zoomed in, so you need to pay attention.

Solution:

Increase the return value oldstep in _getSteps (two steps before (or after) the current step) Then set the left or right positioning in _styleSteps to an invisible one Just the location.

Plug-in prototype: http://www.groupon.com/ Registration function on the homepage, her function (supports up to 3 steps, does not have Versatility)
The plug-in refers to the writing idea of ​​the calendar in UI
Due to the rush of time, the previous step of the plug-in only performed a simple reversible operation.
There will be problems when the width is adaptive: ( This problem exists in the previous step)
The two steps before (and after) the current step will appear in the field of view after the page is zoomed in, so you need to pay attention.
Solution:
Add the return value oldstep in getSteps (two steps before (or after) the current step)
Then set the left or right positioning in styleSteps to an invisible position.
You can wait for the next revision or modify it yourself. Please let us know after modification, thank you!
