大佬们好,咨询一个JavaScript 在Acrobat PDF 内取值的问题,利用正则表达式(/(SN[\:\=\s][ ]*(\w+)(\d{6,10})(\s)(\n)(\w+)(\d{6,10}))/g)取以下2个数据,如何输出的时候按 SN: 002JM034523/FX13231413 这种中间加"/"的方式显示,而不是和原数据那样换行?

完整的代码如下:
// This is a combination of strict and relaxed versions of ISBN number format
var reISBN=/(SN[\:\=\s][ ]*(\w+)(\d{6,10})(\s)(\n)(\w+)(\d{6,10}))/g;
var strExt = "_Ex_SN2.pdf";
var strIntro = "SN numbers extracted from document: ";
var strFinal = "Total number of SN numbers extracted: " ;
ExtractFromDocument(reISBN,strExt,strIntro,strFinal);
function ExtractFromDocument(reMatch, strFileExt, strMessage1, strMessage2)
{
var chWord, numWords;
// construct filename for output document
var filename = this.path.replace(/\.pdf$/, strFileExt);
// create a report document
try {
var ReportDoc = new Report();
var Out = new Object(); // array where we will collect all our emails before outputing them
ReportDoc.writeText(strMessage1 + this.path);
ReportDoc.divide(1); // draw a horizontal divider
ReportDoc.writeText(" "); // write a blank line to output
for (var i = 0; i < this.numPages; i++)
{
numWords = this.getPageNumWords(i);
var PageText = "";
for (var j = 0; j < numWords; j++) {
var word = this.getPageNthWord(i,j,false);
PageText += word;
}
var strMatches = PageText.match(reMatch);
if (strMatches == null) continue;
// now output matches into report document
for (j = 0; j < strMatches.length; j++) {
Out[strMatches[j]] = true; // store email as a property name
}
}
var nTotal = 0;
for (var prop in Out)
{
ReportDoc.writeText(prop);
nTotal++;
}
ReportDoc.writeText(" "); // output extra blank line
ReportDoc.divide(1); // draw a horizontal divider
ReportDoc.writeText(strMessage2 + nTotal);
// save report to a document
ReportDoc.save(
{
cDIPath: filename
});
}
catch(e)
{
app.alert("Processing error: "+e)
}
} // end of the function
