Question

我正在使用Google Closure，而我正在尝试制作Chrome打包应用。

我对goog.require的调用导致错误：

Uncaught document.write() is not available in packaged apps.

罪魁祸首在base.js

goog.writeScriptTag_ = function(src) {
  if (goog.inHtmlDocument_()) {
    var doc = goog.global.document;

    // If the user tries to require a new symbol after document load,
    // something has gone terribly wrong. Doing a document.write would
    // wipe out the page.
    if (doc.readyState == 'complete') {
      // Certain test frameworks load base.js multiple times, which tries
      // to write deps.js each time. If that happens, just fail silently.
      // These frameworks wipe the page between each load of base.js, so this
      // is OK.
      var isDeps = /\bdeps.js$/.test(src);
      if (isDeps) {
        return false;
      } else {
        throw Error('Cannot write "' + src + '" after document load');
      }
    }

    doc.write(
        '<script type="text/javascript" src="' + src + '"></' + 'script>');
    return true;
  } else {
    return false;
  }
};

Google Closure与Google Chrome打包应用程序不兼容吗？ Closure对大型Javascript项目有很多好处，很难放弃这样一个有价值的工具。

编辑：我知道如果除Closure库之外还使用了Closure Compiler，那么就没有goog.require，但这显然使得开发和调试变得更加困难。

Closure Dev Mode & Chrome Packaged App -- "document.write() is not available in the sandbox of packaged apps"

只要您运行它未编译或不使用高级编译进行编译，您必须使用document.createElement（“script”）重新编写doc.write;

所以用以下代码替换te doc.write行：

  var script = document.createElement('script');
  script.src = src;
  script.type = 'text/javascript';
  goog.global.document.getElementsByTagName("head")[0].appendChild(script);
  return true;

高级编译代码不应该需要它，因为它将所有使用过的代码放在一个文件中。

Google Closure和Chrome打包应用：兼容性？
