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 1327 1327: def a(href = "") # :yield: 1328: attributes = if href.kind_of?(String) 1329: { "HREF" => href } 1330: else 1331: href 1332: end 1333: if block_given? 1334: super(attributes){ yield } 1335: else 1336: super(attributes) 1337: end 1338: 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 1349 1349: def base(href = "") # :yield: 1350: attributes = if href.kind_of?(String) 1351: { "HREF" => href } 1352: else 1353: href 1354: end 1355: if block_given? 1356: super(attributes){ yield } 1357: else 1358: super(attributes) 1359: end 1360: 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 1372 1372: def blockquote(cite = nil) # :yield: 1373: attributes = if cite.kind_of?(String) 1374: { "CITE" => cite } 1375: else 1376: cite or "" 1377: end 1378: if block_given? 1379: super(attributes){ yield } 1380: else 1381: super(attributes) 1382: end 1383: 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 1396 1396: def caption(align = nil) # :yield: 1397: attributes = if align.kind_of?(String) 1398: { "ALIGN" => align } 1399: else 1400: align or "" 1401: end 1402: if block_given? 1403: super(attributes){ yield } 1404: else 1405: super(attributes) 1406: end 1407: 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 1426 1426: def checkbox(name = "", value = nil, checked = nil) 1427: attributes = if name.kind_of?(String) 1428: { "TYPE" => "checkbox", "NAME" => name, 1429: "VALUE" => value, "CHECKED" => checked } 1430: else 1431: name["TYPE"] = "checkbox" 1432: name 1433: end 1434: input(attributes) 1435: 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 checkbox_group("name", ["foo"], ["bar", true], "baz") # <INPUT TYPE="checkbox" NAME="name" VALUE="foo">foo # <INPUT TYPE="checkbox" CHECKED NAME="name" VALUE="bar">bar # <INPUT TYPE="checkbox" NAME="name" VALUE="baz">baz checkbox_group("name", ["1", "Foo"], ["2", "Bar", true], "Baz") # <INPUT TYPE="checkbox" NAME="name" VALUE="1">Foo # <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"])
# File lib/cgi.rb, line 1480 1480: def checkbox_group(name = "", *values) 1481: if name.kind_of?(Hash) 1482: values = name["VALUES"] 1483: name = name["NAME"] 1484: end 1485: values.collect{|value| 1486: if value.kind_of?(String) 1487: checkbox(name, value) + value 1488: else 1489: if value[value.size - 1] == true 1490: checkbox(name, value[0], true) + 1491: value[value.size - 2] 1492: else 1493: checkbox(name, value[0]) + 1494: value[value.size - 1] 1495: end 1496: end 1497: }.to_s 1498: 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.

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

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".
