Hi,
I think you have three options here:
1. Change the value of leading of the applied paragraph style "myStyle"
That would be the most effective way. But would be document wide.
Something like this:
app.documents[0].paragraphStyles.itemByName("myStyle").leading = myLeading;
2. If you want to override the applied paragraph style's formatting with a new leading value, you could restrict the scope of your Find/Replace to e.g. the story of some selected text and do it like that:
var doc = app.documents[0];
// The paragraph style we like to find:
var paraStyleToFind = doc.paragraphStyles.itemByName("myStyle");
// The value you like to change:
var myLeadingToChange = Leading.AUTO;
// Define the principle scope of find/replace, e.g. selected text or the document or a specific story
var myScope = app.selection[0].parentStory;
// Restrict or widen your scope:
app.findChangeTextOptions.properties =
{
includeFootnotes : true ,
includeHiddenLayers : true ,
includeMasterPages : true
/*
others as well, see DOM documentation e.g. for InDesign CS6
http://jongware.mit.edu/idcs6js/pc_FindChangeTextOption.html
*/
};
// First set all needed properties application wide:
// Clear the Find/Change dialog first:
app.findTextPreferences = null;
app.changeTextPreferences = null;
// What we like to find by formatting:
app.findTextPreferences.properties =
{
appliedParagraphStyle : paraStyleToFind
};
// What we like to change by formatting:
app.changeTextPreferences.properties =
{
leading : myLeadingToChange
};
// Change the text in the range of the defined scope:
myScope.changeText();
// Clear the Find/Change dialog at the end:
app.findTextPreferences = null;
app.changeTextPreferences = null;
3. But perhaps—depending on your situation—the best thing you could do is to add a new paragraph style that is based on the one you are looking for, changing the leading there and apply the new paragraph style to the text you are looking for. You could do this with a scripting pattern as shown with option 2 above.
There are plenty of examples for Text- or Grep Find/Change in the InDesign scripting forum. Perhaps more with Grep Find/Change than on Text Find/Change. But the used patterns basically are the same. See also the DOM documentation for InDesign for specific properties and methods.
