Indesign Script: replacing all cases of (https) with (http) without duplication

Question

I am trying to fix all of the hyperlinks in my indesign files, and replace the https with http. right now, in order for it to work, I run this script..

var
  i;
hls = app.activeDocument.hyperlinkURLDestinations;
for (i = 0; i < hls.length; i++) {
  if (!hls[i].destinationURL.match('http://')) {
    hls[i].destinationURL = 'http://' + hls[i].destinationURL;
  }
}

followed by this script, choosing https to be replaced by http...

Menu for find/replace

main();
function main(){
 var d = app.dialogs.add({name:"Replace Hyperlink URL Values"});
 var col1 = d.dialogColumns.add();
 var col2 = d.dialogColumns.add();
 col1.staticTexts.add({staticLabel:"Find (GREP):"});
 col1.staticTexts.add({staticLabel:"Replace:"});
 var find = col2.textEditboxes.add({minWidth:100});
 var change = col2.textEditboxes.add({minWidth:100});
 var result = d.show();
 if(!result){
  d.destroy();
  return;
 }
 var grepForFind = RegExp(find.editContents,"g");
 var grepForReplace = change.editContents;
 d.destroy();
 var dests = app.documents[0].hyperlinkURLDestinations.everyItem().getElements();
 for(var i=0;i<dests.length;i++){
  dests[i].destinationURL = dests[i].destinationURL.replace(grepForFind,grepForReplace);
 }
}

Once both of these have been ran, I notice that the "http://" has been duplicated on the hyperlinks that already contain "http://".

So I run the second script again replacing (http:// + http://) with "http://" which solves the problem.

My question, is how to make it into a single script that would work the first time.

**Note:**The second script presents this error if the first is not run, which baffles me as well.

Any and all help would be appreciated.

Answer 1

On the first script you get http:// duplicated because you are adding it to its own reference i.e. "http://"+"http://…". You have to replace string, not to add it:

var
  i;
hls = app.activeDocument.hyperlinkURLDestinations;
for (i = 0; i < hls.length; i++) {
  if (!hls[i].destinationURL.match('http://')) {
    hls[i].destinationURL = hls[i].destinationURL.replace(/^https/,"http");
  }
}

Another approach:

Hyperlink.prototype.grep = function(findString,repString, specifiers){
 var r, dests = this.destination, url, dest, n = dests.length;
 
 if ( !n 
 || !findString
 || !repString
 || typeof (findString) != "string"
 || typeof (repString) != "string"
 || ( specifiers && typeof ( specifiers )!="string" )
 ) return;
 
 r = new RegExp ( findString, specifiers? specifiers:"gi" );
 
 while (n-- ) {
  dest = dests[n];
  if ( dest instanceof HyperlinkURLDestination ) {
   url = dest.destinationURL;
   dest.destinationURL = url.replace ( r, repString );
  }
 }
}

main();
function main(){
 var d = app.dialogs.add({name:"Replace Hyperlink URL Values"});
 var col1 = d.dialogColumns.add();
 var col2 = d.dialogColumns.add();
 col1.staticTexts.add({staticLabel:"Find (GREP):"});
 col1.staticTexts.add({staticLabel:"Replace:"});
 var find = col2.textEditboxes.add({minWidth:100, editContents:"^https"});
 var change = col2.textEditboxes.add({minWidth:100, editContents:"http"});
 var result = d.show();
 if(!result){
  d.destroy();
  return;
 }

 var grepForFind = RegExp(find.editContents,"g");
 var grepForReplace = change.editContents;
 app.documents[0].hyperlinks.everyItem().grep(find.editContents, change.editContents, "g");
 d.destroy();
}

I ran over all the configurations and to the exception of an empty url destination that indeed thrown an error, I can't reproduce what you are facing. Maybe give this new snippet a try ? If still failing, any chance you share the file ? Go at ozalto.com on the contact page if you prefer.

Hyperlink.prototype.grep = function(findString,repString, specifiers){
 var r, dests = this.destination, url, dest, n = dests.length;
 
 if ( !n 
 || !findString
 || !repString
 || typeof (findString) != "string"
 || typeof (repString) != "string"
 || ( specifiers && typeof ( specifiers )!="string" )
 ) return;
 
 r = new RegExp ( findString, specifiers? specifiers:"gi" );
 
 while (n-- ) {
  dest = dests[n];
  if ( dest instanceof HyperlinkURLDestination ) {
   url = dest.destinationURL;
   url!="" && dest.destinationURL = url.replace ( r, repString );
  }
 }
}

main();
function main(){
 var d = app.dialogs.add({name:"Replace Hyperlink URL Values"});
 var col1 = d.dialogColumns.add();
 var col2 = d.dialogColumns.add();
 col1.staticTexts.add({staticLabel:"Find (GREP):"});
 col1.staticTexts.add({staticLabel:"Replace:"});
 var find = col2.textEditboxes.add({minWidth:100, editContents:"^https"});
 var change = col2.textEditboxes.add({minWidth:100, editContents:"http"});
 var result = d.show();
 if(!result){
  d.destroy();
  return;
 }

 var grepForFind = RegExp(find.editContents,"g");
 var grepForReplace = change.editContents;
 app.documents[0].hyperlinks.everyItem().grep(find.editContents, change.editContents, "g");
 d.destroy();
}
