无法解析错误-怎么了？

Question

这是“未能解析错误”行-> var label = package.getComment（）&& package.getComment（）：'N / A'

其余代码... var脚本='/home/paulomacedo/jd2/JD_HOME/jdownloader-postprocess.sh'

var path = package.getDownloadFolder() 
var name = package.getName() 
var label = package.getComment() && package.getComment() : 'N/A' 
var links = package.getDownloadLinks() ? package.getDownloadLinks() : []

function isReallyFinished() {
    for (var i = 0; i < links.length; i++) {
        if (links[i].getArchive() != null && links[i].getExtractionStatus() != "SUCCESSFUL" || !package.isFinished()) {
            return false
        }
    }
    return true
}

if (isReallyFinished()) {
    var command = [script, path, name, label, 'PACKAGE_FINISHED']
    log(command)
    log(callSync(command))
}

Answer 1

错误在这里：

var label = package.getComment() && package.getComment() : 'N/A' 
//                                                       ^

您正确地希望使用三元运算符 ：

var label = package.getComment() ? package.getComment() : 'N/A' 

或a && b || c a && b || c ：

var label = package.getComment() && package.getComment() || 'N/A'
