在Google Docs应用脚本中循环查找和替换

function findAndReplace(searchPattern, replacementText) {
  var body = DocumentApp.getActiveDocument().getBody();
  var searchHeading = 'SEARCH';
  var replaceHeading = 'REPLACE';

  // 创建查找和替换对话框

  ui.setSandboxMode(HtmlService.SandboxMode.IFRAME);
  ui.showModalDialog(ui, '查找和替换');

  // 查找和替换函数
  function findAndReplace(searchPattern, replacementText) {
    var found = false;
    while (true) {
      var result = body.findText(searchPattern);
      if (!result) break;
      found = true;

    }
    return found ? '查找和替换完成' : '未找到匹配的文本';
