Question

我正在尝试在活动页面上找到所有“＃”并将其更改为数字，即。 1,2,3。。

以下代码是我认为可行的，但事实并非如此。相反，它将每个“＃”更改为“0”。

app.findTextPreferences = app.changeTextPreferences = NothingEnum.NOTHING;
app.findTextPreferences.findWhat = "#";

var finds = app.activeDocument.findText();
if (finds.length > 0) {
   for (var i = 0; i < finds.length; i++)  
   {  
      app.changeTextPreferences.changeTo = "no: " + i;
      app.activeDocument.changeText();
   }  
   else
   {
      alert("Nothing has been found");
   }
}

Answer 1

正如ali haydar所说，changeText将全局应用并将打破以前的findText文本引用。你需要的是在你的循环中使用contents属性。

app.findTextPreferences = app.changeTextPreferences = NothingEnum.NOTHING;
app.findTextPreferences.findWhat = "#";

var finds = app.activeDocument.findText();
if (finds.length > 0) 
{
    for (var i = 0; i < finds.length; i++)  
    {  
      finds[i].contents = "no: " + String(i);
    }  
}
else
{
alert("Nothing has been found");
}

事实上你甚至可以摆脱if条件：

app.findTextPreferences = app.changeTextPreferences = null;
app.findTextPreferences.findWhat = "#";

var finds = app.activeDocument.findText();
var n = finds.length;
var nStart = n;
while (n-- ) finds[n].contents = "no: " + String(n+1);
alert(nStart? nStart+" replacements made…" : "Nothing has been found");

仅考虑第1页......

var main = function(){
    var doc = app.properties.activeDocument,
     finds,n;

    app.findTextPreferences = app.changeTextPreferences = null;
    app.findTextPreferences.findWhat = "#";

    if ( !doc ) return;
    finds = doc.findText();
    n = finds.length;

    while (n-- ) {
        finds[n].parentTextFrames.length
        && finds[n].parentTextFrames[0].isValid
        && finds[n].parentTextFrames[0].parentPage.id==doc.pages[0].id
        && finds[n].contents = "no: " + String(n+1);
    }

};

main();
