Firebug常用自带函数：

命令	说明
$(id)	通过id返回Element。
$$(selector)	通过CSS选择器返回Element数组。
$x(xpath)	通过xpath表达式返回Element数组。
dir(object)	列出对象的所有属性，和在DOM标签页查看该对象的是一样的。
dirxml(node)	列出节点的HTML或XML的源代码树，和在HTML标签页查看改节点一样。
cd(window)	默认情况下，命令行相关的是顶层window对象，使用该命令可切换到frame里的window独享。
clear()	清空信息显示区，和单击按钮Clear功能一样。
inspect(object[, tabName])	监视一个对象。tabName表示在那个标签页对该对象进行监视，可选值为“html”、“css”、“script”和“dom”。
keys(object)	返回由对象的属性名组成的数组。
values(object)	返回由对象的属性值组成的数组。
debug(fn)	在函数的第一行增加一个断点。
undebug(fn)	移除在函数第一行的断点。
monitor(fn)	跟踪函数fn的调用。
unmonitor(fn)	不跟踪函数fn的调用。
monitorEvents(object[, types])	跟踪对象的事件。Types的可选值为“composition”、 “contextmenu”、 “drag”、 “focus”,、“form”、“key”、 “load”、“mouse”、“mutation”、“paint”、“scroll”、“text”、“ui”和“xul”。
unmonitorEvents(object[, types])	不跟踪对象的事件。Types的可选值为“composition”、 “contextmenu”、 “drag”、 “focus”,、“form”、“key”、 “load”、“mouse”、“mutation”、“paint”、“scroll”、“text”、“ui”和“xul”。
profile([title])	开始对脚本进行性能测试，可选参数title将作为测试结果的标题。
profileEnd()	结束脚本性能测试。

单击功能区第二栏的“HTML”标签可切换到源代码查看功能。虽然Firefox也提供了查看页面源代码的功能，但它显示的只是页面文件本身的源代码，通过脚本输出的HTML源码是看不到。而Firebug则是所见即所得，是最终的源代码（包括运行时JS自动生成的Html标签，这些是在FF自带Html查看器或是IE的“查看页面源码”里看不到的）。

信息区被分成了两个部分，左边是显示源代码，右边是一个功能区，可以从这里查看到HTML Element中的CSS定义、布局情况和DOM结构。

在源代码上移动鼠标，页面就会出现一个半透明的方块，指示当前鼠标所指源代码的显示区域。如将鼠标放到上图<table id=”1” cellspacing…….时，页面相应位置被方块选中

如果选择“查看”，功能正好相反，在页面中移动鼠标，则当前显示区域的源代码会被加亮显示出来。

编辑页面的Html元素有几种方式：

1.单击源码标签部分，在弹出的编辑框里进行编辑，按Tab可以切换需要编辑的属性

<!--[if !supportLists]-->4. <!--[endif]-->修改元素的布局（margin、border、padding），Firebug提供一个可视化编辑器，我们将右边的区域切换到“布局”标签，你会看到一个盒子模型，里面从外到里通过不同的线和颜色划分出了offset、margin、border、padding和内容五个区域，里面4个区域在每个边上都有1个数值，表示该方向上的调整值。

将功能区第二行的标签切换到“CSS”，在这里我们可以查看页面中所有的CSS定义，包括链接的CSS文件。通过功能区的文件选择按钮可以选择不同的含有CSS的文件

<!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:PunctuationKerning /> <w:DrawingGridVerticalSpacing>7.8 磅</w:DrawingGridVerticalSpacing> <w:DisplayHorizontalDrawingGridEvery>0</w:DisplayHorizontalDrawingGridEvery> <w:DisplayVerticalDrawingGridEvery>2</w:DisplayVerticalDrawingGridEvery> <w:ValidateAgainstSchemas /> <w:SaveIfXMLInvalid>false</w:SaveIfXMLInvalid> <w:IgnoreMixedContent>false</w:IgnoreMixedContent> <w:AlwaysShowPlaceholderText>false</w:AlwaysShowPlaceholderText> <w:Compatibility> <w:SpaceForUL /> <w:BalanceSingleByteDoubleByteWidth /> <w:DoNotLeaveBackslashAlone /> <w:ULTrailSpace /> <w:DoNotExpandShiftReturn /> <w:AdjustLineHeightInTable /> <w:BreakWrappedTables /> <w:SnapToGridInCell /> <w:WrapTextWithPunct /> <w:UseAsianBreakRules /> <w:DontGrowAutofit /> <w:UseFELayout /> </w:Compatibility> <w:BrowserLevel>MicrosoftInternetExplorer4</w:BrowserLevel> </w:WordDocument> </xml><![endif]--><!--[if gte mso 9]><xml> <w:LatentStyles DefLockedState="false" LatentStyleCount="156"> </w:LatentStyles> </xml><![endif]--> <!--[if gte mso 10]> <mce:style><! /* Style Definitions */ table.MsoNormalTable {mso-style-name:普通表格; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} --> <!--[endif]-->

CSS的定义的编辑这里就不再说明了，这个可以参考HTML的“Style”操作。

“Edit”按钮功能和HTML的“Edit”功能类似。

五、 <!--[endif]-->脚本调试

将功能区第二行的标签切换到“脚本”，在这里我们可以对页面中所有的脚本进行调试，包括链接的脚本。和CSS一样，可以通过文件选择按钮选择不同的脚本文件。

<!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:PunctuationKerning /> <w:DrawingGridVerticalSpacing>7.8 磅</w:DrawingGridVerticalSpacing> <w:DisplayHorizontalDrawingGridEvery>0</w:DisplayHorizontalDrawingGridEvery> <w:DisplayVerticalDrawingGridEvery>2</w:DisplayVerticalDrawingGridEvery> <w:ValidateAgainstSchemas /> <w:SaveIfXMLInvalid>false</w:SaveIfXMLInvalid> <w:IgnoreMixedContent>false</w:IgnoreMixedContent> <w:AlwaysShowPlaceholderText>false</w:AlwaysShowPlaceholderText> <w:Compatibility> <w:SpaceForUL /> <w:BalanceSingleByteDoubleByteWidth /> <w:DoNotLeaveBackslashAlone /> <w:ULTrailSpace /> <w:DoNotExpandShiftReturn /> <w:AdjustLineHeightInTable /> <w:BreakWrappedTables /> <w:SnapToGridInCell /> <w:WrapTextWithPunct /> <w:UseAsianBreakRules /> <w:DontGrowAutofit /> <w:UseFELayout /> </w:Compatibility> <w:BrowserLevel>MicrosoftInternetExplorer4</w:BrowserLevel> </w:WordDocument> </xml><![endif]--><!--[if gte mso 9]><xml> <w:LatentStyles DefLockedState="false" LatentStyleCount="156"> </w:LatentStyles> </xml><![endif]--> <!--[if gte mso 10]> <mce:style><! /* Style Definitions */ table.MsoNormalTable {mso-style-name:普通表格; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} --> <!--[endif]-->

<!--[if !supportLists]-->六、 <!--[endif]-->DOM查看器

将功能区第二行的标签切换到“DOM”可俺层次查看整个页面的DOM结构。通过“Options”菜单可自定义选择查看用户自定义属性（Show User-defined Properties）、用户自定义函数（Show User-defined Functions）、DOM属性（Show DOM Properties）、DOM函数(Show DOM Functions)或DOM常数(Show DOM Constants)等内容。
