Question

我有switch()需要包含多个条件才能成为真实在线社区告诉我，我应该在两种情况下将它们分开然后定义它。像这样：

function changeGrep(searchFor){
app.findGrepPreferences.findWhat = searchFor;
var myFound = myDoc.findGrep();
for(i=0; i<myFound.length; i++){
    switch(searchFor){
        case "^201\\d$":
        case myFound[i].parent.fillColor == app.activeDocument.swatches.item(14):
            myFound[i].parent.fillColor = app.activeDocument.swatches.item(3);
            break;

        case "^-?\\+?\\(?((\\d+,)?(\\d+,)?(\\d+)(\\.\\d+)?%?\\)?)$":
        case myFound[i].parent.fillColor == app.activeDocument.swatches.item(14):
            myFound[i].parent.fillColor = app.activeDocument.swatches.item(4);
            break;

        }
    }
}

changeGrep("^-?\\+?\\(?((\\d+,)?(\\d+,)?(\\d+)(\\.\\d+)?%?\\)?)$");
changeGrep("^201\\d$");

首先，整个表格都以红色(14)放置。如果两个条件为真，则应更改颜色。但是，它并不关心第二个case。

有关如何在extendcript中执行此操作的任何想法？

你可以试试这个香草JS解决方案。将true传递给switch语句，然后每个案例都可以包含一个条件。

switch (true) {
  case (<condition> && <condition>):
    // do something
    break;
  case (searchFor === '^201\\d$'):
    // do other thing
    break;
  case ((searchFor === '^201\\d$') && (myFound[i].parent.fillColor == app.activeDocument.swatches.item(14)):
    // code
    break;
}

如果你跳过switch声明，我认为这可能会更清晰（也更快）。

我首先要弄清楚，你的替换样本将是什么，然后在循环中你只需要弄清楚，如果父对象有正确的替换样本，如果是，请替换为替换样本。 / p>

function changeGrep(searchFor){
  app.findGrepPreferences.findWhat = searchFor;
  var myFound = myDoc.findGrep();

  var myReplaceSwatch;
  if(searchFor === "^201\\d$") {
    myReplaceSwatch = app.activeDocument.swatches.item(3);
  } else if (searchFor === "^-?\\+?\\(?((\\d+,)?(\\d+,)?(\\d+)(\\.\\d+)?%?\\)?)$") {
    myReplaceSwatch = app.activeDocument.swatches.item(4);
  }

  for (var i = 0; i < myFound.length; i++) {
    if(myReplaceSwatch && myFound[i].parent.fillColor === app.activeDocument.swatches.item(14) {
      myFound[i].parent.fillColor = myReplaceSwatch;
    }
  }
}

changeGrep("^-?\\+?\\(?((\\d+,)?(\\d+,)?(\\d+)(\\.\\d+)?%?\\)?)$");
changeGrep("^201\\d$");

或者，为了简化更多，你也可以将样本的索引传递给函数：

function changeGrep(searchFor, swatchIndex){
  app.findGrepPreferences.findWhat = searchFor;
  var myFound = myDoc.findGrep();

  var myReplaceSwatch = app.activeDocument.swatches.item(swatchIndex);

  for (var i = 0; i < myFound.length; i++) {
    if(myReplaceSwatch && myFound[i].parent.fillColor === app.activeDocument.swatches.item(14) {
      myFound[i].parent.fillColor = myReplaceSwatch;
    }
  }
}

changeGrep("^-?\\+?\\(?((\\d+,)?(\\d+,)?(\\d+)(\\.\\d+)?%?\\)?)$", 4);
changeGrep("^201\\d$", 3);
