Question

我的任务是在Js中为剪纸脚本组合两个if语句。它是一个打印管理软件。我拥有我所需的一切，我相信下面的脚本。我认为问题在于将这两个“如果”合并为一个陈述。我不熟悉Javascript，也不熟悉python。我希望在重新整理此脚本方面有所帮助，如下所述。

PaperCut print script API reference

目标：

如果打印作业超过10页，则仅执行费用中心弹出窗口，否则仅将其自动记入公司的非计费（ADM-3900）帐户。如果作业超过50页，请将其从HP重定向到较大的复印机。在这种情况下，从test_printer3到“复印机–颜色”。

我相信这是您要寻找的东西，但尚不完全清楚。在不知道所有逻辑分支的情况下很难合并条件。

 */


 var LIMIT             = 5; // Redirect jobs over 5 pages.
 var HIGH_VOL_PRINTER  = "Copier - Color";  

if (!inputs.job.isAnalysisComplete) { 
 return;// No job details yet so return. 
} 


//Charge jobs with less than 10 pages to non-bill account
if (inputs.job.totalPages < 10) {
  // Charge to the firm non-bill account
  actions.job.chargeToSharedAccount(ADM-3900);
} 
else //Charge jobs with more than 10 pages to the personal account
{   
    actions.job.chargeToPersonalAccount();

      if (inputs.job.totalPages > LIMIT) {
        /*

        actions.job.bypassReleaseQueue();

        /*

                         + "' to printer '" + HIGH_VOL_PRINTER + "'.");
      }
}
   return
}

我认为您遇到的问题必须处理您提到的if语句块中的多个return语句。

这个街区就是你所拥有的...

if (!inputs.job.isAnalysisComplete) {
    return;
    actions.job.chargeToPersonalAccount();
    return;

    if (inputs.job.totalPages < 10) {
        actions.job.chargeToSharedAccount(ADM-3900);
    } 
}

我认为，如果是这样的话，该区块会更准确...

/*No details of print analysis?  Return the the function immediately!*/
if (!inputs.job.isAnalysisComplete) {
    return;
} 

/*Job less than ten pages?  Charge shared account.  Otherwise charge personal account.*/
if (inputs.job.totalPages < 10) {

    /*Also, my bet is that the ADM-3900 needs to be in quotes for a string unless other wise stated in the manual.*/

    actions.job.chargeToSharedAccount("ADM-3900");
} else {
    actions.job.chargeToPersonalAccount();
}

注意，这是我最好的猜测，因为我对Papercut软件不熟悉。

如果那没有帮助，总会有technical support

根据您对目标的理解，我将对您的代码进行下一步更改：

// Setup limit for charge the job to ADM-3900.

var ADM_3900_CHARGE_LIMIT = 10;

// Setup of redirection for larger jobs.

var REDIRECT_PAGE_LIMIT = 50;
var REDIRECT_PRINTER  = "Copier - Color";

function printJobHook(inputs, actions)
{    
    /*
    * This print hook will need access to all job details

    }

    // If pages to print is less than ADM_3900_CHARGE_LIMIT,

Answer 5

您的文字翻译为：

if(jobs > 50) redirect to Copier-Color
elseif(jobs > 10) cost center popup
else charge automagically

在JS中应该是：

const   LIMIT_10            = 10,
        LIMIT_50            = 50,
        HIGH_VOL_PRINTER  = "Copier - Color";

function printJobHook(inputs, actions) {
    if (!inputs.job.isAnalysisComplete)
        return;

    if (inputs.job.totalPages > LIMIT_50) {
        actions.job.bypassReleaseQueue();
        actions.job.redirect(HIGH_VOL_PRINTER, {allowHoldAtTarget: true});
        actions.client.sendMessage(
          "The print job was over " + LIMIT + " pages and was sent to " 
          + " printer: " + HIGH_VOL_PRINTER + ".");

        actions.log.info("Large job redirected from printer '" + inputs.job.printerName 
                         + "' to printer '" + HIGH_VOL_PRINTER + "'.");
    }else if (inputs.job.totalPages > LIMIT_10) {
        actions.job.chargeToSharedAccount();
    }else{
        actions.job.chargeToPersonalAccount(ADM-3900);
    }
}
