我正在尝试遍历InDesign文档中的各个层，并将所有层设置为可见。这是为了确保正确进行文件收集。
我整理了以下内容
var myDocument = app.activeDocument;
//make all layers visable
for (i = 0; i < myDocument.layers.length; i++) {
if(myDocument.layers[i].visible = false) {
myDocument.layers[i].visible = true;
};
};
这摘自一个自动执行文件收集的较大脚本，这只是图层的例程。
对于上下文，这是实际的脚本。
function Left(str, n){
if (n <= 0)
return "";
else if (n > String(str).length)
return str;
else
return String(str).substring(0,n);
}
function Right(str, n){
if (n <= 0)
return "";
else if (n > String(str).length)
return str;
else {
var iLen = String(str).length;
return String(str).substring(iLen, iLen - n);
}
}
if (app.documents.length != 0){
var myDocument = app.activeDocument;
var docName = myDocument.name;
var docName = Left(docName, String(docName).length-5)
//alert(docName);
var myFolder = new Folder ("~/Desktop/"+docName+"/");
//myFolder.create("Bob");s
/*new Folder ("~/Desktop/Collected/Hi-Res PDF/");
new Folder ("~/Desktop/Collected/RELEASE INFO/");*/
//make all layers visable
for (i = 0; i < myDocument.layers.length; i++) {
if(myDocument.layers[i].visible = false) {
myDocument.layers[i].visible = true;
};
};
myDocument.packageForPrint (myFolder,1,1,0,1,0,0,0);
var newFolder = new Folder ("~/Desktop/"+docName+"/RELEASE INFO/");
newFolder.create();
var inddFolder = new Folder ("~/Desktop/"+docName+"/Indesign Files/");
inddFolder.create();
var newFolder = new Folder ("~/Desktop/"+docName+"/IDML Files/");
newFolder.create();
//Export IMDL File
myDocument.exportFile(ExportFormat.INDESIGN_MARKUP, File("~/Desktop/"+docName+"/IDML Files/"+docName+".idml"), false);
//Move INDD File
//var myInddfile = File("~/Desktop/"+docName+"/"+docName+".indd");
//myDocument.changePath(File(inddFolder),false);
//Rip Low Res PDFs
var myPDFExportPreset = app.pdfExportPresets.item("CP3 Low Rez");
app.activeDocument.exportFile(ExportFormat.pdfType,
File("~/Desktop/"+docName+"/RELEASE INFO/"+docName+"_LR.pdf"), false, myPDFExportPreset);
//Now export the document. You'll have to fill in your own file path.
//app.activeDocument.exportFile(ExportFormat.pdfType, File("~/Desktop/"+docName+"_FILM/RELEASE INFO/"+docName+"_LR.pdf"), false);
var newFolder = new Folder ("~/Desktop/"+docName+"/Hi-Res PDF/");
newFolder.create();
//Rip Hi-Res PDF
var myPDFExportPreset = app.pdfExportPresets.item("Kern Hi Rez Print");
app.activeDocument.exportFile(ExportFormat.pdfType,
File("~/Desktop/"+docName+"/Hi-Res PDF/"+docName+"_HiRes.pdf"), false, myPDFExportPreset);
//Now export the document. You'll have to fill in your own file path.
//app.activeDocument.exportFile(ExportFormat.pdfType, File("~/Desktop/"+docName+"_FILM/Hi-Res PDF/"+docName+"_HiRes.pdf"), false);
myFolder.execute();
}
else{
alert("Please open a document and try again.");
}
希望当脚本执行时，所有层都将设置为可见，然后将进行文件收集。
在if语句中使用三重等于表示严格相等。例如：
for (i = 0; i < myDocument.layers.length; i++) {
if(myDocument.layers[i].visible === false) { // <-- Note the `===` instead of `=`
myDocument.layers[i].visible = true;
};
};
甚至更好，您可以更改它以使用逻辑NOT!运算符
for (i = 0; i < myDocument.layers.length; i++) {
if (!myDocument.layers[i].visible) { // <-- Change to this.
myDocument.layers[i].visible = true;
};
};
注意：在您的示例中，条件if语句实际上不是必需的。您可以简单地这样做：
for (i = 0; i < myDocument.layers.length; i++) {
myDocument.layers[i].visible = true;
};
如果您实际上想使所有内容可见-包括；InDesign文档层以及子层上的所有页面项目，那么您需要执行以下示例：
var myDocument = app.activeDocument;
// ...
function makeAllVisible() {
for (i = 0, max = myDocument.layers.length; i < max; i++) {
var currentLayer = myDocument.layers[i];
currentLayer.visible = true; // Make the top level layer visible.
// Make all sub layers visible,
// i.e. make all page items on the current layer visible.
var currentLayerPageItems = currentLayer.allPageItems;
for (x = 0, len = currentLayerPageItems.length; x < len; x++) {
currentLayerPageItems[x].visible = true
}
}
}
makeAllVisible(); // Invoke the function.
// ...
