现在我正在开发一个用于汇合的用户宏,它创建了一个提供类别的空格列表。我是Confluence开发的新手,之前从未使用过Velocity,但我设法让宏工作。
但是有一个问题:每当我使用.add()
方法时,模板会打印出true
,所以我从宏中得到的是一些true
字符串+列表我想要。如何避免打印true
?为什么要打印?
这是整个宏代码

## @param Label:title=Space Category|type=string|required=true|desc=The categories the spaces should have. Use Pipe to separate categories.
## create list out of provided category string
#set($labelList = $paramLabel.split("\|"))
#set($spacesByLabel = [])
## try to fetch all spaces for each category
#foreach ($spaceLabel in $labelList)
#set($label = $action.labelManager.getLabel( "team:${spaceLabel}"))
#if ($!label)
#$spacesByLabel.add($action.labelManager.getSpacesWithLabel( $label ))
#else
<div class="aui-message warning">
<p class="title">
<span class="aui-icon icon-warning">Warning</span>
<strong>Space category not found</strong>
</p>
<p>Couldn't find space category <strong>$spaceLabel</strong>!</p>
</div>
#end

## filter out all spaces that are not in all categories
#set($spacesInAll = [])

<ul class="spaces-by-category-user-macro">
#foreach ( $space in $spacesInAll )
## check if current user can view space
#if ( $permissionHelper.canView( $action.getAuthenticatedUser(), $space ) )
<li><a href="$!space.urlPath">$!space.name</a></li>
#end
#end

#set ( $d = "$") ## escape the dollar sign for jQuery in velocity

## Sort the list client side as this can't be done server side in a user macro.
AJS.toInit(function (${d}) {
${d}('.spaces-by-category-user-macro').each(function(){
var ${d}me = ${d}(this);
// Sort the list items
var listItems = ${d}me.children('li').get();
listItems.sort(function(x,y) {
var compareX = ${d}(x).text().toUpperCase();
var compareY = ${d}(y).text().toUpperCase();
return (compareX < compareY) ? -1 : (compareX > compareY) ? 1 : 0;
});
// Write the list items back to the DOM
${d}.each(listItems, function(index, item) { ${d}me.append(item); });
});
});

好的,我找到了一个&#34;解决方法&#34;我认为......或解决方案......但对我而言,这似乎不仅仅是一种解决方法:
如果您将.add()
方法封装在#set()
方法中,则可以将方法的输出(true
)重定向到一个变量,以防止它被打印出来。
所以电话会是这样的:
#set($result = $list.add($whatsoever))
答案 1 :(得分:2)
我也遇到了这个问题,并尝试提出一个解决方案,以避免使用#set()
和虚拟变量。似乎在Confluence中,.add()
的输出必须封装在更多的Velocity代码中才能呈现。
这是我能提出的最简单的解决方案,但它仍然让我想要抓住我的眼睛:
#if( $array.add($data) ) #end
