| In: |
lib/cgi.rb
|
Mixin module providing HTML generation methods.
For example,
cgi.a("http://www.example.com") { "Example" }
# => "<A HREF=\"http://www.example.com\">Example</A>"
Modules Http3, Http4, etc., contain more basic HTML-generation methods (:title, :center, etc.).
See class CGI for a detailed example.
Generate an Anchor element as a string.
href can either be a string, giving the URL for the HREF attribute, or it can be a hash of the element’s attributes.
The body of the element is the string returned by the no-argument block passed in.
a("http://www.example.com") { "Example" }
# => "<A HREF=\"http://www.example.com\">Example</A>"
a("HREF" => "http://www.example.com", "TARGET" => "_top") { "Example" }
# => "<A HREF=\"http://www.example.com\" TARGET=\"_top\">Example</A>"
# File lib/cgi.rb, line 1311
1311: def a(href = "") # :yield:
1312: attributes = if href.kind_of?(String)
1313: { "HREF" => href }
1314: else
1315: href
1316: end
1317: if block_given?
1318: super(attributes){ yield }
1319: else
1320: super(attributes)
1321: end
1322: end
Generate a Document Base URI element as a String.
href can either by a string, giving the base URL for the HREF attribute, or it can be a has of the element’s attributes.
The passed-in no-argument block is ignored.
base("http://www.example.com/cgi")
# => "<BASE HREF=\"http://www.example.com/cgi\">"
# File lib/cgi.rb, line 1333
1333: def base(href = "") # :yield:
1334: attributes = if href.kind_of?(String)
1335: { "HREF" => href }
1336: else
1337: href
1338: end
1339: if block_given?
1340: super(attributes){ yield }
1341: else
1342: super(attributes)
1343: end
1344: end
Generate a BlockQuote element as a string.
cite can either be a string, give the URI for the source of the quoted text, or a hash, giving all attributes of the element, or it can be omitted, in which case the element has no attributes.
The body is provided by the passed-in no-argument block
blockquote("http://www.example.com/quotes/foo.html") { "Foo!" }
#=> "<BLOCKQUOTE CITE=\"http://www.example.com/quotes/foo.html\">Foo!</BLOCKQUOTE>
# File lib/cgi.rb, line 1356
1356: def blockquote(cite = nil) # :yield:
1357: attributes = if cite.kind_of?(String)
1358: { "CITE" => cite }
1359: else
1360: cite or ""
1361: end
1362: if block_given?
1363: super(attributes){ yield }
1364: else
1365: super(attributes)
1366: end
1367: end
Generate a Table Caption element as a string.
align can be a string, giving the alignment of the caption (one of top, bottom, left, or right). It can be a hash of all the attributes of the element. Or it can be omitted.
The body of the element is provided by the passed-in no-argument block.
caption("left") { "Capital Cities" }
# => <CAPTION ALIGN=\"left\">Capital Cities</CAPTION>
# File lib/cgi.rb, line 1380
1380: def caption(align = nil) # :yield:
1381: attributes = if align.kind_of?(String)
1382: { "ALIGN" => align }
1383: else

1387: super(attributes){ yield }
1388: else
1389: super(attributes)
1390: end
1391: end
Generate a Checkbox Input element as a string.
The attributes of the element can be specified as three arguments, name, value, and checked. checked is a boolean value; if true, the CHECKED attribute will be included in the element.
Alternatively, the attributes can be specified as a hash.
checkbox("name")
# = checkbox("NAME" => "name")
checkbox("name", "value")
# = checkbox("NAME" => "name", "VALUE" => "value")
checkbox("name", "value", true)
# = checkbox("NAME" => "name", "VALUE" => "value", "CHECKED" => true)
# File lib/cgi.rb, line 1410
1410: def checkbox(name = "", value = nil, checked = nil)
1411: attributes = if name.kind_of?(String)
1412: { "TYPE" => "checkbox", "NAME" => name,
1413: "VALUE" => value, "CHECKED" => checked }
1414: else
1415: name["TYPE"] = "checkbox"
1416: name
1417: end
1418: input(attributes)
1419: end
Generate a sequence of checkbox elements, as a String.
The checkboxes will all have the same name attribute. Each checkbox is followed by a label. There will be one checkbox for each value. Each value can be specified as a String, which will be used both as the value of the VALUE attribute and as the label for that checkbox. A single-element array has the same effect.
Each value can also be specified as a three-element array. The first element is the VALUE attribute; the second is the label; and the third is a boolean specifying whether this checkbox is CHECKED.
Each value can also be specified as a two-element array, by omitting either the value element (defaults to the same as the label), or the boolean checked element (defaults to false).
checkbox_group("name", "foo", "bar", "baz")
# <INPUT TYPE="checkbox" NAME="name" VALUE="foo">foo
# <INPUT TYPE="checkbox" NAME="name" VALUE="bar">bar
# <INPUT TYPE="checkbox" NAME="name" VALUE="baz">baz

# <INPUT TYPE="checkbox" CHECKED NAME="name" VALUE="2">Bar
# <INPUT TYPE="checkbox" NAME="name" VALUE="Baz">Baz
checkbox_group("NAME" => "name",
"VALUES" => ["foo", "bar", "baz"])
checkbox_group("NAME" => "name",
"VALUES" => [["foo"], ["bar", true], "baz"])
checkbox_group("NAME" => "name",
"VALUES" => [["1", "Foo"], ["2", "Bar", true], "Baz"])

1472: else
1473: if value[value.size - 1] == true

1478: value[value.size - 1]
1479: end
1480: end
1481: }.to_s
1482: end
Generate an File Upload Input element as a string.
The attributes of the element can be specified as three arguments, name, size, and maxlength. maxlength is the maximum length of the file’s name, not of the file’s contents.
Alternatively, the attributes can be specified as a hash.
See multipart_form() for forms that include file uploads.
file_field("name")
# <INPUT TYPE="file" NAME="name" SIZE="20">
file_field("name", 40)
# <INPUT TYPE="file" NAME="name" SIZE="40">

1513: end
1514: attributes["MAXLENGTH"] = maxlength.to_s if maxlength
1515: input(attributes)
1516: end
Generate a Form element as a string.

Generate a Hidden Input element as a string.
The attributes of the element can be specified as two arguments, name and value.
Alternatively, the attributes can be specified as a hash.

1586: name
1587: end
1588: input(attributes)
1589: end
Generate a top-level HTML element as a string.
The attributes of the element are specified as a hash. The pseudo-attribute "PRETTY" can be used to specify that the generated HTML string should be indented. "PRETTY" can also be specified as a string as the sole argument to this method. The pseudo-attribute "DOCTYPE", if given, is used as the leading DOCTYPE SGML tag; it should include the entire text of this tag, including angle brackets.
The body of the html element is supplied as a block.

Generate a Select element as a string.
name is the name of the element. The values are the options that can be selected from the Select menu. Each value can be a String or a one, two, or three-element Array. If a String or a one-element Array, this is both the value of that option and the text displayed for it. If a three-element Array, the elements are the option value, displayed text, and a boolean value specifying whether this option starts as selected. The two-element version omits either the option value (defaults to the same as the display text) or the boolean selected specifier (defaults to false).
The attributes and options can also be specified as a hash. In this case, options are specified as an array of values as described above, with the hash key of "VALUES".

Generate a sequence of radio button Input elements, as a String.
This works the same as checkbox_group(). However, it is not valid to have more than one radiobutton in a group checked.
radio_group("name", "foo", "bar", "baz")
# <INPUT TYPE="radio" NAME="name" VALUE="foo">foo

Generate a reset button Input element, as a String.
This resets the values on a form to their initial values. value is the text displayed on the button. name is the name of this button.
Alternatively, the attributes can be specified as a hash.
