Styles

###Styles

Create styles with HTML tag names from an object. The object matches the InDesign DOM. So you can pass them to the paragraphStyles.add() method directly.

//Wrap it up in an anonymous function
(function(thisObj) {

  // paragraph style object
  // these will be passed directly to the paragraphStyles.add() method
  // so only use property names that exist in the ID DOM
  var parstyles = [{
    "name": "p",
    appliedFont: "Museo Slab\t300"
  }, {
    "name": "h1"
  }, {
    "name": "h2"
  }, {
    "name": "h3"
  }, {
    "name": "h4"
  }, {
    "name": "h5"
  }, {
    "name": "h6"
  }, {
    "name": "quote"
  }];

  // same here for the character styles
  var charstyles = [{
    "name": "em"
  }, {
    "name": "bold"
  }, {
    "name": "link"
  }];

  var doc = app.activeDocument; // current front most document
  var prevp = null; // the get the based on working
  // loop the parsytles
  for (var i = 0; i < parstyles.length; i++) {
    // check if there is already a style with that name
    var pexists = doc.paragraphStyles.itemByName(parstyles[i].name);
    if (pexists !== null) {
      // there was one set it back to null and skip this one
      pexists = null;
      continue; //<-- This skips
    }
    // there was no style with this name. So create it
    var p = doc.paragraphStyles.add(parstyles[i]);
    if (prevp !== null) {
      // if we already have a previous style set the basedOn property
      p.basedOn = prevp;
    }
    prevp = p; // <-- set current to previous
  }
  // same here for the character styles
  // but we don't set the basedOn feature
  for (var j = 0; j < charstyles.length; j++) {
    var cexists = doc.characterStyles.itemByName(charstyles[j].name);
    if (cexists !== null) {
      cexists = null;
      continue;
    }
    var c = doc.characterStyles.add(charstyles[j]);

  }

})(this);

Style your text with nested styles. This script file needs to be saved to work.

     */
    // a function
    // this script has to be saved somewhere
    // or this wont work

      documentPreferences:{
          pageWidth:pw,pageHeight:ph
          }
      });
    
        // build a style with nested grep styles
        var code = build_code_paragraphStyle (doc);
        // get the page
        var page = doc.pages[0];
