在智能向导退步的时候跳过验证 [英] Skip validation when going backwards in SmartWizard

问题描述

我使用的SmartWizard 2.0（链接），我需要停止验证从当用户点击了preV按钮，或以任何方式踢的形式向后移动。

I am using the SmartWizard 2.0 (link) and I need to stop the validation from kicking in when the users hits the "Prev" button or in any way moves backward in the form.

目前我使用

// Triggers whenever you change page/tab in wizard    
function leaveStep(obj) {        
    $("form").validate();
    if ($("form").valid())
        return true;

    return false;
}

我知道，我可以使用

I know that I can use

var currentStep = obj.attr('rel'); // get the current step number

找currentStep，但我需要知道用户正在浏览哪个方向 - 所以我需要知道NextStep自动。不知道这是可能的。

to find the currentStep, but I need to know which way the user is navigating - so I need to know the "nextStep". Don't know if this is possible.

推荐答案

在 onLeaveStep 触发你能不能用OBJ来确定方向？然后，你会移动到下一个步骤时，只验证？

When onLeaveStep is triggered could you not use the obj to determine the direction? Then you would only validate when moving to the next step?

更新：

查看源$ C ​​$ C后，没有办法，我可以看到找出方向。在能力修补然而pretty容易。在jquery.smartWizard-2.0.js变线186

After looking at the source code, there is no way that I can see to figure out the direction. Patching in the ability is pretty easy however. In jquery.smartWizard-2.0.js change line 186 from

if(!options.onLeaveStep.call(this,$(curStep))){

到

if(!options.onLeaveStep.call(this,$(curStep),$(selStep))){

这现在可以访问所选步骤锚，因此所选择的阶跃折射率。要在onLeaveStep处理简单的确定方向做到以下几点：

This now gives you access to the selected step anchor, and thus the selected step index. To determine the direction in your onLeaveStep handler simple do the following:

// Triggers whenever you change page/tab in wizard    
function leaveStep(from, to) {
    var fromStepIdx = from.attr( "rel" );
    var toStepIdx = to.attr( "rel" );

    if ( toStepIdx < fromStepIdx )
    {
        return true;
    }

    $("form").validate();
    if ($("form").valid())
        return true;

    return false;
}
