私が考えることができる最高のは、それがvolStrで\」とは何かを持っていますが、私はそれを他の方法を作成する方法がわからないです。
@Mulvyaのコメントの後、私は、各グループの間のスペースを取り除くと、それは美しく働いたばかり
var volStr = '';
for (var i = 0; i < arrPairs.length; i++) {
volStr += "volume=enable='between(t," + arrPairs[i].start + "," + arrPairs[i].end + ")':volume=0";
if (i !== arrPairs.length - 1) {
volStr += ",";
}
}
にループのための私を変えました。
'はありません、このようなフィルタ：「 - 終了引用符が追加されていないためか、volume'『volume''それは、フィルタ名が 'であると考えて』。空白を避けることができれば、開始時と終了時に二重引用符を取り除くことができます。 – Mulvya
@Mulvya空白を取り除くことについてのあなたの提案は美しく働いた！あなたが答えとしてそれを入れたいなら、私はそれを喜んで正しいものとしてマークします！ – shaun
