xpages:比较两个视图之间的值

我打算比较两个视图之间的值。

想象一下view1具有以下值:

Location | Officer
Australia| Peter
Beglium  | John
Chile    | Ben
Italy    | Mike

想象一下view2具有以下值:

Item     | Location
Book     | Italy
Journal  | Australia
Movie    | Spain

我想要做的是比较view1和view2之间的值。

我写下面的代码:

var location = sessionScope.Location;
var message = "";
var view1 = @DbLookup(@DbName(), "view1", location , 0)); // use session scope variable to lookup in view1 and find location
var view2 = @DbLookup(@DbName(), "view2", view1 , 1)); // use view1 value to lookup in view

for(var x = 0; x < view1.length; x++)
{
    for(var y = 0; y < view2.length; y++)
    {
       if(view1[x] == view2[y])//if value exist in view1 and view2
       {
           message = "value matches";
       }
       else // if not match
       {
           message = "value does not match";
       }
       // show the result in the excel
      //first row list all values in view1 and the second row will show the message
       writer.write("<tr><td>" + view1[x] + "</td></tr>" + message  + "</td></tr>");
    }
}

当我运行程序时,我看到view1 [x]工作正常,因为它可以在view1中显示值,但是关于显示消息,它只显示“值不匹配”,即使view1和view2中存在该值。 / p>

结果如下所示:

Australia | value does not match
Beglium   | value does not match
Chile     | value does not match
Italy     | value does not match

我想知道为什么消息只显示else部分而不确定为什么它没有为view1 [x]中的每个值显示正确的消息。

实际上我认为结果会是这样的:

Australia | value matches
Beglium   | value does not match
Chile     | value does not match
Italy     | value matches

代码中的错误是什么?感谢您的建议。谢谢。

将您的代码更改为

for(var x = 0; x < view1.length; x++) {
    message = "value does not match";
    for(var y = 0; y < view2.length; y++) {
       if(view1[x] == view2[y]) {
           message = "value matches";
           break;
       }
    }
    // show the result in the excel
    //first row list all values in view1 and the second row will show the message
    writer.write("<tr><td>" + view1[x] + "</td></tr>" + message  + "</td></tr>");
}
