如何使用 JavaScript 在 InDesign 中为字符加下划线?
How to underline charachters in InDesign with JavaScript?
我开始为 InDesign 编写这段代码,为除带有后代的字母外的所有字母添加下划线,并添加了一个对话框 window 来选择线条的笔划和偏移量。
现在我有两个问题:
- 程序为所有字母加下划线
- 行程和偏移不会改变
我是 Javascript 的初学者,这是第一次为 InDesign 编码。有人有线索吗?谢谢!
// UNDERLINE ALL BUT NO DESCENDANTS
//Make certain that user interaction (display of dialogs, etc.) is turned on.
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.interactWithAll;
if (app.documents.length != 0){
try {
// Run script with single undo if supported
if (parseFloat(app.version) < 6) {
main();
} else {
app.doScript(main, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, "Expand State Abbreviations");
}
// Global error reporting
} catch ( error ) {
alert( error + " (Line " + error.line + " in file " + error.fileName + ")");
}
}else{
alert("Open a document first before running this script.");
}
///MAIN FUNCTION
function main(){
if(app.selection.length != 0){
myDisplayDialog();
}
}
//INTERFACE
function myDisplayDialog(){
//declare variables
//general
var myDoc = app.activeDocument;
var mS = myDoc.selection;
// dialog
var myDialog = app.dialogs.add({name:"Underliner"});
var myLabelWidth = 70;
with(myDialog.dialogColumns.add()){
with(borderPanels.add()){
with(dialogColumns.add()){
with(dialogRows.add()){
staticTexts.add({staticLabel:"Stroke:", minWidth:myLabelWidth});
staticTexts.add({staticLabel:"Offset:", minWidth:myLabelWidth});
}
}
with(dialogRows.add()){
staticTexts.add({staticLabel:""});
var myStroke = measurementEditboxes.add({editValue:1, editUnits:MeasurementUnits.points});
var myOffset = measurementEditboxes.add({editValue: 15, editUnits:MeasurementUnits.points});
}
}
}
var myResult = myDialog.show();
if(myResult == true){
var myStroke = myStroke.editValue;
var myOffset = myOffset.editValue;
myDialog.destroy();
underline(mS,myStroke,myOffset);
}
else{
myDialog.destroy();
alert("Invalid page range.");
}
}
//REAL FUNCTION
function underline(charList,stroke, offset){
var len = charList.length;
const doNotUnderline = ['g','j','p','q','y'];
for (var i=0; i < len; i++){
try{
var myChar = charList[i];
//console.log(typeof myText);
if (includes(myChar, doNotUnderline) == false)
{
myChar.underline = true;
myChar.underlineWeight == stroke;
myChar.underlineOffset == offset;
} else {
myChar.underline = false;
}
}catch(r){
alert(r.description);
break;
}
}
}
//function to know if char is in array
function includes(elemento,array)
{
var len = array.length;
for(var i=0; i<len ;i++)
{
if(array[i]==elemento){return true;}
}
return false;
}
尝试在函数中进行这些更改 underline()
:
//REAL FUNCTION
function underline(words,stroke, offset) { // <------ here 'words' instead of 'charList'
var charList = words[0].characters; // <------ here get 'characters' of the 'words'
var len = charList.length;
const doNotUnderline = ['g','j','p','q','y'].join(); // <------- here '.join()'
for (var i=0; i < len; i++){
try{
var myChar = charList[i];
// if (includes(myChar, doNotUnderline) == false) // <----- no need
if (doNotUnderline.indexOf(myChar.contents) < 0) // <------ 'indexOf()' instead of 'includes()'
{
myChar.underline = true;
myChar.underlineWeight = stroke; // <------- here '=' instead of '=='
myChar.underlineOffset = offset; // <------- here '=' instead of '=='
} else {
myChar.underline = false;
}
}catch(r){
alert(r.description);
break;
}
}
}
可能还有其他改进。它需要额外的研究。但是,如果您更改这些行,它应该会在一定程度上起作用。
还有一件小事可以极大地改善用户体验:在输入字段中保留上次使用的值。它可以很容易地完成,让我知道你需要它。
更新
这是我用来存储和恢复我的脚本的任何首选项的方式。
在脚本开头的某处添加这些行:
// get preferences
var PREFS = { stroke: 1, offset: 15 }; // set default prefs
var PREFS_FILE = File(Folder.temp + '/underline_prefs.json'); // the file with preferences
if (PREFS_FILE.exists) PREFS = $.evalFile(PREFS_FILE); // get the prefs from the file
现在您可以在任何地方使用全局值 PREFS.stroke
和 PREFS.offset
。在你的情况下,他们去这里:
with(dialogRows.add()){
staticTexts.add({staticLabel:""});
var myStroke = measurementEditboxes.add({editValue:PREFS.stroke, editUnits:MeasurementUnits.points});
var myOffset = measurementEditboxes.add({editValue:PREFS.offset, editUnits:MeasurementUnits.points});
}
这样脚本将从文件 underline_prefs.json
中获取 stroke
和 weight
,这些文件将存储在当前用户的标准临时文件夹中。
最后一步是在脚本从对话框 window.
中获取值后将它们保存回文件中
我会把这段代码放在这里:
if (myResult == true) {
var myStroke = myStroke.editValue;
var myOffset = myOffset.editValue;
myDialog.destroy();
underline(mS, myStroke, myOffset);
// save preferences here
PREFS.stroke = myStroke;
PREFS.offset = myOffset;
PREFS_FILE.open('w');
PREFS_FILE.write(PREFS.toSource());
PREFS_FILE.close();
} else {
myDialog.destroy();
alert("Invalid page range.");
}
瞧瞧。现在不需要在每次与默认值不同时都键入值。
