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');

        }
    }

这将由您用于生成报告的链接处理。通常添加 _blank 的目标就可以了。例如：

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

这将在新选项卡中打开链接。

如果您正在使用表单，则向表单添加目标会将表单提交到新选项卡。例如：

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

或者

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

如果需要，您甚至可以使用 javascript 来执行此操作window.open，但我会将这个示例排除在此答案之外，因为它在其他地方都有很好的记录。
