我有一个运行良好的脚本，但可能需要很长时间才能完成。这是一个 javascript 文档并运行多个函数。

该脚本在 InDesign 中运行，并且基于 javascript。ExtendScript Toolkit 提供了几个演示脚本，其中之一是SnpCreateProgressBar.jsx.

现在我想将进度条添加到我当前的脚本中，但我不完全确定如何执行此操作。

在不在这里发布整个代码的情况下，我将执行一个函数。这在整个脚本中重复。

var myDoc = app.activeDocument;
var myTables = myDoc.stories.everyItem().tables.everyItem();
var myTableElements = myTables.getElements();

function basicSearchReplace(findWhat, changeTo){
    app.findGrepPreferences = app.changeGrepPreferences = null;
    app.findChangeGrepOptions = NothingEnum.nothing;
    app.findGrepPreferences.findWhat = findWhat;
    app.changeGrepPreferences.changeTo = changeTo;
    myDoc.changeGrep();
}    


basicSearchReplace ('^~8 ', '~8\\t');
basicSearchReplace ('^·( |\\t)',  '~8\\t');

SnpCreateProgressBar.jsx可以在这里找到

也许还有另一种扩展脚本方法来创建进度条？

--- 小更新 ---
所以经过一些谷歌搜索和测试后，我想出了：

function SnpCreateProgressBar () 
{
    this.windowRef = null;
}

SnpCreateProgressBar.prototype.run = function() {
var win = new Window("palette", "SnpCreateProgressBar", [150, 150, 600, 260]);   
win.pnl = win.add("panel", [10, 10, 440, 100], "Script Progress");  
win.pnl.progBar = win.pnl.add("progressbar", [20, 35, 410, 60], 0, 100);  
win.pnl.progBarLabel = win.pnl.add("statictext", [20, 20, 320, 35], "0%");  

win.show();  

                while(win.pnl.progBar.value < win.pnl.progBar.maxvalue)  
                {  

                          // this is what causes the progress bar increase its progress  
                          win.pnl.progBar.value++;   
                            win.pnl.progBarLabel.text = win.pnl.progBar.value+"%";  
                          $.sleep(10);  
                }  

alert('Done!');   

win.close();  
};
if(typeof(SnpCreateProgressBar_unitTest) == "undefined") {
    new SnpCreateProgressBar().run();
}

现在我想我还没有完全理解。如果我将我的“待运行”代码放在 while 循环中，它只会执行该代码并在最后运行进程栏......底部的 if 循环也是如此

我不明白什么？
