贾斯珀报告：如何编译子报表(Jasper Reports: How to compile subreports)

 我有一个独立的应用程序，其职责之一是采取* .jrxml文件的路径并编译它。 
 

 直到带有子报表的报表出现，其中主表的编译没有编译它的任何子项，导致子报表* .jasper文件在跟踪后面找不到，我可以毫无问题地做到这一点。 
 

 有什么办法可以 
 

 1）设置JasperCompileManager自动获取子报表？ 
 

 2）获取包含在JasperDesign或JasperReport对象中的子报表的路径列表？ 
 

 我无法直接访问jrxml文件，因此修改报告以适应编译方法不是一种选择，也不适用任何标准命名方案来推断哪些子报告属于哪些报告。 
 

 这里有一个类似的问题： 
 

 http://jasperforge.org/plugins/espforum/view.php?group_id=102&forumid=103&topicid=40683 
 

 使用JRVisitor生成JRSubreport对象列表，但是没有解释如何使用它来获取子报表的路径，以便编译它并递归查找子报表的子报表，我无法弄清楚。 

I have a standalone application, and one of its duties is to take the path of a *.jrxml file and compile it.
 

I can do this without problem until a report with a subreport comes up, where the compilation of the master does not compile any of its children, resulting in a subreport *.jasper file not found later down the track.
 

Is there any way to
 

1) Set the JasperCompileManager to automatically pick up subreports?
 

2) Get a list of paths to subreports contained within either a JasperDesign or JasperReport object?
 

I have no direct access to the jrxml files, so modifying the reports to suit the compile method is not an option, nor is applying any standard naming scheme to infer which subreports belong to which reports.
 

There is a similar problem here:
 

http://jasperforge.org/plugins/espforum/view.php?group_id=102&forumid=103&topicid=40683
 

where a JRVisitor is used to produce a list of JRSubreport objects, however there is no explanation of how to use this to get a path to the subreport in order to compile it and recursively look for subreports of subreports, and I cant figure it out.

 使用change事件而不是click 。 也可以使用toggleClass而不是首先检查元素是否具有使用hasClass的类，然后添加/删除它。 
 

 演示 
 

 

 
 
 
  
$("fieldset.radio label").change(function() {
  $("fieldset.radio label").removeClass("radioselect");
  $(this).addClass("radioselect");
});

$("fieldset.check label").change(function(e) {
  $(this).toggleClass("checkselect");
});

 如果您可以更改HTML结构，则根本不需要JS复选框。 
 

     
 
  1.  将复选框元素移出label 
    2.  
 
  2.  将id添加到复选框，并将属性值添加到相应的label 
    3.  
 
  3.  使用:checked属性和相邻的兄弟CSS选择器为选中的复选框设置样式 
    4.

Use change event instead of click. Also use toggleClass instead of first checking if the element have a class using hasClass and then adding/removing it.

  $("fieldset.radio label").removeClass("radioselect");
  $(this).addClass("radioselect");
});

$("fieldset.check label").change(function(e) {
  $(this).toggleClass("checkselect");
});

If you can change the HTML structure, you don't need JS at all for checkbox.
 

     
 
  1. Move the checkbox element out of the label
    2.  
 
  2. Add id to the checkbox and same as for attribute value to the corresponding label
    3.  
 
  3. Use :checked property and adjacent sibling CSS selector to set styles for the checked checkbox
    4.
