在grails中使用jasper插件在新选项卡中打开报告 [英] Open report in new tab using jasper plugin in grails

问题描述

我使用jasper插件来生成我的报告。一切都很好，但除了我的pdf在当前选项卡上打开时，我想在新选项卡中打开它。

我不知道该怎么做。有谁可以请帮助我吗？

我使用i-report来设计我的pdf。以下是我的代码：

  def index = {
 println（params）
 def testModel = this .getProperties（）。containsKey（'chainModel'）？ 
 chainModel：null 
 
 JasperReportDef report = null 
 if（params.containsKey（'auto_print_dialog'））{
 
 report = docuJasperService.buildReportDefinition（params ，
 request.getLocale（），testModel）
} 
 else {
 report = jasperService.buildReportDefinition（params，
 request.getLocale（），testModel）
} 
 generateResponse（报告）
} 
 
 def generateResponse = {reportDef  - > 
 if（！reportDef.fileFormat.inline&&！reportDef.parameters._inline）{
 //response.characterEncoding =UTF-8
 //response.setHeader（ Content-disposition，
 //inline; filename = $ {params._name}）; 
 $ b $ response.setHeader（Content-disposition，inline; 
 filename =+（reportDef.parameters._name？：reportDef.name）+ 
。+ reportDef.fileFormat.extension）; 
 response.contentType =application / pdf
 response.outputStream<< reportDef.contentStream.toByteArray（）
} else {
 
 render（text：reportDef.contentStream，contentType：
 reportDef.fileFormat.mimeTyp，
 encoding：reportDef。 parameters.encoding？
 reportDef.parameters.encoding：'UTF-8'）; 
 
 
 $ b  

解决方案

这将由您用来生成报告的链接处理。通常添加一个_blank的目标将做到这一点。例如：

 < g：link controller =myReportsaction =whateverReporttarget =_ blank>点击为您的报告< / g：link> 
  

这会打开新标签中的链接。

如果您使用表单添加目标到表单将提交表单到一个新的选项卡。例如：

 < form name =myFormaction =whateverReportmethod =POSTtarget =_ blank > 
  

或

 < g：form name =myFormcontroller =myReportsaction =whateverReporttarget =_ blank> 
  

您甚至可以使用javascript window.open


I am using jasper plugin to generate my report. All is fine but except my pdf is opening on the current tab, when I want to open it in a new tab.

I have no idea how to do it. Can anybody please help me on this please?

I am using "i-report" to design my pdf. Here is my code below :

 def index = {
        println(params)
        def testModel = this.getProperties().containsKey('chainModel') ? 
                       chainModel : null

        JasperReportDef report = null
        if (params.containsKey('auto_print_dialog')){

            report = docuJasperService.buildReportDefinition(params,
            request.getLocale(), testModel)
        }
        else{
            report = jasperService.buildReportDefinition(params, 
                     request.getLocale(), testModel)
        }
        generateResponse(report)
    }

    def generateResponse = {reportDef ->
        if (!reportDef.fileFormat.inline && !reportDef.parameters._inline) {
     //response.characterEncoding = "UTF-8"
      //response.setHeader("Content-disposition", 
      //"inline; filename=${params._name}");

          response.setHeader("Content-disposition", "inline; 
          filename="+(reportDef.parameters._name ?: reportDef.name) + 
                   "."+reportDef.fileFormat.extension);
            response.contentType = "application/pdf"
            response.outputStream << reportDef.contentStream.toByteArray()
        } else {

        render(text: reportDef.contentStream, contentType:
               reportDef.fileFormat.mimeTyp,
               encoding: reportDef.parameters.encoding ? 
               reportDef.parameters.encoding : 'UTF-8');

        }
    }

解决方案

This is going to be handled by the link you use to generate the report. Typically adding a target of _blank will do the trick. For example:

<g:link controller="myReports" action="whateverReport" target="_blank">Click for your report</g:link>

This will open the link in a new tab.

If you are using a form adding target to the form will submit the form to a new tab. For example:

<form name="myForm" action="whateverReport" method="POST" target="_blank">

or

<g:form name="myForm" controller="myReports" action="whateverReport" target="_blank">

You could even do so with javascript window.open if you needed, but I will leave that example out of this answer as it's well documented elsewhere.
