google-apps-script - Google Apps 脚本：如何从 textArea 获取文本？（替换文本）

Question

我需要替换 textArea 中的文本，我做错了什么？

function doGet() {
  var app = UiApp.createApplication();
  var textArea = app.createTextArea()
  .setText('here is text... here is text... here is text...')
  .setName('theText').setId('theText')
  .addClickHandler(app.createServerHandler('processing'));
  app.add(textArea);
  return app;
}

function processing(e) {
  Logger.log(e.parameter.theText); // In Log I see: 'here is text... here is text... here is text...'
  var textIn = e.parameter.theText;
  var textOut = textIn.replaceText('/[text]/', 'new text'); // Here I get error: Unable to find a function replaseText in the object here is text... here is text... here is text....
  var app = UiApp.getActiveApplication();
  app.getElementById('theText').setText(textOut);
  return app;  
}

我用'e.parameter.theText'尝试了getText、getBody、editAsText等，但结果相同。错误在哪里？

该replace方法很简单replace，而不是replaceText 纯JavaScript。 您似乎混淆了DocumentApp和 Javascript 字符串操作。
