Xpages 在查看 FTSearch 后没有结果 [英] Xpages no results after FTSearch on view

问题描述

我的应用程序中有一个搜索模块，可根据用户选择过滤多个视图.

I have a search module in my application which filters multiple views, depending on the user choice.

如果搜索没有结果，我想添加一个对话框，而不是将视图显示为空.我该怎么做?

I want to add a dialog if the search has no results, instead of showing the view empty. How can I do this?

我尝试获取 rowCount() 但它似乎没有获取正确的行数，我不知道为什么.

I have tried to get rowCount() but it seems it is not getting the right number of rows, I don't know why.

SSJS 代码:

var vw=database.getView("vwCautareDocI");
var tmpArray = new Array("");
var cTerms = 0; 
var dateFormatter = new java.text.SimpleDateFormat( "MM-dd-yyyy" ); 

if (sessionScope.numprenum) { 
   tmpArray[cTerms++] = "(Field NumePrenume = \"*" + sessionScope.numprenum + "*\")"; 
} 

if (sessionScope.postvizat) { 
   tmpArray[cTerms++] = "(Field PostulVizat = \"*" + sessionScope.postvizat + "*\")"; 
} 

if (sessionScope.din && sessionScope.pana) {
    tmpArray[cTerms++] = "Field _creationDate >= " + dateFormatter.format(sessionScope.din) + " AND Field _creationDate <= " + dateFormatter.format(sessionScope.pana);
}


filter = tmpArray.join(" AND ").trim(); 
var vec=vw.getAllDocumentsByKey(filter , true);
return vec.getCount();

这是我用来过滤视图的过滤器.我想将此代码添加到按钮中，如果结果为 0，那么它应该显示一个带有消息的对话框，而不是显示视图.

This is the filter I use to filter my view. I wanted to add this code to a button, and if the result is 0 then instead of showing the view, it should show a dialog with a message.

推荐答案

getAllDocumentsByKey 和 fTSearch 方法在视图上做不同的事情.您正在尝试返回第一列与您正在使用的全文搜索条件匹配的条目数.我怀疑该视图未按该标准分类.

getAllDocumentsByKey and fTSearch methods do different things on the view. You're trying to return the number of entries where the first column matches the full text search criteria you're using. I suspect the view is not categorised on that criteria.
