Firebug Script 調試記錄

• Your new friend, console.log? //顯示變量　參數
  

console.log,　console.debug, console.info, console.warn,　console.error...

console.log("hello?world")

console.log(2,4,6,8,"foo",bar)

console.log("%a,%b","foo",bar)?//?"%"用于定義量

console.log("%s?is?%d?years?old.",?"Bob",?42).

• Timing and profiling? // 時間及性能分析

console.profile();　//性能開始
console.time("test");　//時間開始
function?Test()
{
??for(var?i?=?0;?i?<?10;?i++)
????{
??????console.info("this?is?a?test");
????}??
}
Test();
console.timeEnd("test");　//時間結束
console.profileEnd();　　//　性能結束

• Stack traces　

console.trace()

• Nested grouping

Just call console.group("a title") to start a new indentation block, and then console.groupEnd() to close the block. You can create as many levels of indentation as you please.

• Object inspection　　//　顯示對象信息

Calling console.dir(object) will log an interactive listing of an object's properties, like a miniature version of the DOM tab.

Calling console.dirxml(element) on any HTML or XML element will print a lovely XML outline, like a miniature version of the HTML tab.

console.dir(document.getElementById("sleCategory"));
console.dirxml(document.getElementById("sleCategory"));
