문제

WebKit/사파리를 지원하는 콘솔체는 것과 유사한 방화 않습니다.그러나 정확히 무엇입을 지원합니까?가 콘솔에 대한 설명서 방화, 지만,어디에서 찾을 수 있습니 콘솔에 대한 문서 사파리/웹킷?

도움이 되었습니까?

해결책

지원 방법은 원래:

  • console.log()
  • console.error()
  • console.warn()
  • console.info()

최신 버전의 WebKit 또한 추가 할 다음의 방법을 만드는 웹킷 콘솔 API 거의 동일 방화의 콘솔 API:

  • console.count()
  • console.debug()
  • console.profileEnd()
  • console.trace()
  • console.dir()
  • console.dirxml()
  • console.assert()
  • console.time()
  • console.profile()
  • console.timeEnd()
  • console.group()
  • console.groupEnd()

(새로운 정보를 기반으로 웹서 밤을 구축 WebKit-SVN-r37126,글을 쓰는 시점에서 이러한 방법을 사용할 수 없습니다에서 사파리)

다른 팁

콘솔 API 설명서 콘솔 섹션에는 사파리의 개발자 안내합니다.

이것이 오래되고 대답 질문,하지만 당신은 또한 단 콘솔을 열고 유형 console.__proto__, 고,당신을 얻을 것이 있는 팽창할 수 있는 목록의 모든 것을 지원할 수 있습니다.

방화의 콘솔 API 문서 여기로 이사 오기:

http://getfirebug.com/wiki/index.php/Console_API

이것을보십시오:

console.dir(console)

Think of it as the Terminal of your web content. The console has access to the DOM and JavaScript of the open page. Use the console as a tool to modify your web content via interactive commands and as a teaching aid to expand your knowledge of JavaScript. Because an object’s methods and properties autocomplete as you type, you can see all available functions that are valid in Safari.</p><p>For example, open the console and type <code>$$(‘p’)[1]</code>. (<code>$$</code> is shorthand for <code>document.querySelectorAll</code>—see more shorthand commands in <span class="content_text"><a href="#//apple_ref/doc/uid/TP40007874-CH6-SW7" data-renderer-version="1" onclick="s_objectID=&quot;http://web.archive.org/web/20170322101551/https://developer.apple.com/library/content/documentati_10&quot;;return this.s_oc?this.s_oc(e):true">Table 5-1</a></span>.) Because this paragraph is the second instance of the <code>p</code> element on this page (<code>[1]</code> in a 0-based index), the node represents this paragraph. As you hover over the node, its position on the page is visibly highlighted. You can expand the node to see its contents, and even press Command-C to copy it to your clipboard.</p><section><a name="//apple_ref/doc/uid/TP40007874-CH6-SW5" title="Command-Line API"></a><h2 class="jump">Command-Line API</h2><p>You can inspect HTML nodes and JavaScript objects in more detail by using the console commands listed in <span class="content_text">Table 5-1</span>.
