如何使用 JMP 中的 JSL 实现光标指向网页上显示内容的效果？
http://worldmap.ifnews.com/chinamap/china/fmap 
当光标指向地图上的某个国家/地区范围时，就会弹出数据。
谢谢！
或者，您可以编辑 HoverLabel 的“图片”脚本，以触发您想要的任何操作：
打开网页
- 在图表中显示更多信息
- 另开一个地块……
更多详情请见此帖：
回复：鼠标悬停时的操作？ - 使用修饰键：backhand_index_pointing_right::white_square_button:
这种方法的优点：
悬停标签能够识别鼠标当前所在国家/地区，无需查找：
:Country[local:_firstrow]
Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/World Demographics.jmp" );
mapxy = Open( "$MAPS/World-XY.jmp" );
mapname = Open( "$MAPS/World-Name.jmp" );
mapname << New Column( "X", Format( "Longitude DDD", "PUNDIR", 14, 4 ) );
mapname << New Column( "Y", Format( "Latitude DDD", "PUNDIR", 14, 4 ) );
For Each( {rw}, Index( 1, N Rows( mapname ) ),
shapeID = mapName:ShapeID[rw];
rws = mapxy << get rows where( :ShapeID == shapeID & :PartID == 1 );
xs = mapxy[rws, "X"];
ys = mapxy[rws, "Y"];
{x, y} = Polygon Centroid( xs, ys );
mapname:x[rw] = x;
mapname:y[rw] = y;
);
dt << Update( With( mapname ), Match Columns( :Territory = :Region ), Add Columns from Update Table( :X, :Y ) );
New Namespace(
"hover"
);
hover:GDP = 0;
hover:x = 0;
hover:y = 0;
gb = Graph Builder(
Variables( Color( :GDP per Capita ), Shape( :Territory ) ),

SendToReport(

{Format( "Longitude DDD", "PUNDIR", 16 ), Min( 0 ), Max( 30 )}

Dispatch( {}, "", ScaleBox( 2 ),
{Format( "Latitude DDD", "PUNDIR", 16, 0 ), Min( 40 ), Max( 50 )}
),
Dispatch( {}, "Graph Builder", FrameBox,
{Set Graphlet(
Picture(
hover:GDP = :GDP per Capita[local:_firstrow];
hover:x = :X[local:_firstrow];
hover:y = :y[local:_firstrow];
//approach1: select the current country and trigger an update -> nice, but draggy
//local:_dataTable << Clear Select << select rows(local:_firstrow);

)}

);
fb1 = Report( gb )[FrameBox( 1 )];
fb1 << addgraphicsscript(
x = hover:x;
y = hover:y;
Text( center justified, {hover:x, hover:y}, "GDP: " || Char( Round( hover:GDP ) ) );
);
悬停标签是否知道鼠标的当前位置？
遗憾的是，本地:_xaxis/_yaxis=0 。
作为一种变通方法，我采用了这种方法。
https://community.jmp.com/t5/Discussions/exporting-x-amp-y-values-coordinates-from-graph-builder-once-jmp/mp/193660/highlight/true#M41407 @johnmoore计算国家的质心 - 显示 GDP。
作为替代方案，可以使用 Mousetrap（除了 Hover Label 变通方法之外）来获取鼠标的位置。
缺点：交互性较差，因为用户必须按下鼠标按钮。
