如何使用XSP.partialRefreshPost方法禁用验证器？ [英] How to disable validators using the XSP.partialRefreshPost method?

问题描述

我正在使用XSP.partialRefreshPost来触发客户端Javascript的部分刷新。我希望能够在不触发验证器的情况下进行局部刷新（这只是普通输入控件的一个简单属性）。

I am using XSP.partialRefreshPost to trigger a partial refresh from client side Javascript. I would like to be able to do the partial refresh without triggering the validators (which is just a simple attribute on an ordinary input control).

我找到了几个引用一个选项参数，可以与XSP.partialRefreshPost结合使用（包括控制验证的能力）。但是，我没有找到任何描述语法/选项名称的地方???

I have found several references to an "options" argument that you can use in conjuntion with XSP.partialRefreshPost (including the ability to control validation). However, I have not found any places that describes the syntax/option names???

任何人都知道怎么做？

编辑：

好的，我添加了几个我尝试过的例子 - 澄清问题。我也在XPages便携式命令指南中嗤之以鼻。

Ok, I have added a couple of examples of what I have tried - to clarify the issue. I have had my nose in the XPages Portable Command Guide as well.

首先，使用立即参数：

$(".selectCtrl").on("change", function(e){XSP.partialRefreshPost("#{id:repeatCtrl}", {immediate: true})})

然后，使用valmode参数：

Then, using the "valmode" paramter:

$(".selectCtrl").on("change", function(e){XSP.partialRefreshPost("#{id:repeatCtrl}", {params: {'valmode': 0}})})

后者在valmode附近引用了各种报价， 0。

The latter with variations of quotes around "valmode" and "0".

这些都不起作用......（即刷新开始 - 但由验证器失败而停止）。我希望我在这里得到错误的语法 - 但是找不到任何有用的例子 - 但是; - ）

None of these worked... (i.e. the refresh kicks in - but is stopped by the validator failing). I hope that I am just getting the wrong syntax here - but haven't been able to find any working examples - yet ;-)

推荐答案

这是 PhaseListener ，如果需要，它会禁用验证：

Here is a PhaseListener which disables the validation if required:

package ch.hasselba.demo;

import javax.faces.event.PhaseEvent;
import javax.faces.event.PhaseId;
import javax.faces.event.PhaseListener;
import com.ibm.xsp.context.ExternalContextEx;
import com.ibm.xsp.context.FacesContextExImpl;

public class DisableValidationPhaseListener implements PhaseListener {

    private static final long serialVersionUID = 1L;

    public void afterPhase(PhaseEvent arg0) {}

    public void beforePhase(PhaseEvent arg0) {
        FacesContextExImpl fc  = (FacesContextExImpl) arg0.getFacesContext();
        ExternalContextEx ec = (ExternalContextEx) fc.getExternalContext();

        // check for the "disableValidation" parameter & disable validation
        // if required
        if( ec.getRequestParameterMap().containsKey("disableValidation") )
            fc.setDisableValidators(true);
    }

    public PhaseId getPhaseId() {
        return PhaseId.PROCESS_VALIDATIONS;
    }

}

您只需要添加一个参数到你的PartialRefresh，并且验证被禁用：

You just have to add a parameter to your PartialRefresh, and the validation is disabled:

XSP.partialRefreshPost('#{id:refreshMe}', {'params': {'disableValidation':true}} );
