Function

Description

elementValue(attrib) or ev(attrib)

attrib: the name of an attribute

Replaced by the value of the bound attribute whose name is passed as a parameter for the pointed element. For example, ev(id) will be replaced by the value of the id attribute for this element.

Replaced by the element identifier.

polygonArea()

Replaced by the area of a pointed polygon type element.

lineLength()

Replaced by the length of a pointed line type element.

centroid()

Replaced by the coordinates of the geometric centroid of the element's geometry.

format(attrib, format)

attrib: the name of a date or numerical attribute

format: the desired date format

Example: format(attrib, ##0,00)

where attrib is the name of an attribute containing a number and ##0,00 is the desired number format, as indicated in the documentation of the java.text.DecimalFormat Java class.

ifNull(attrib, value)

attrib: the name of the attribute to test

value: the value to display if attrib is null

Replaced by the value only if the value of the attrib attribute is null. If the attribute value is not null, nothing is displayed.

Example: ifNull(temp, N/A)

Displays N/A if the value of the temp attribute is null.

Example: ifNull(attrib_a, attrib_b)

Displays the value of the attrib_b attribute if the value of the attrib_a attribute is null.

ifNotNull(attrib, value)

attrib: the name of the attribute to test

value: the value to display if attrib is not null

Replaced by the value only if the value of the attrib attribute is not null. If the attribute value is null, nothing is displayed.

Example: ifNotNull(land_value, $)

Displays $ only if the value of land_value is not null.

subString(attrib, startIx, endIx)

attrib: the name of the attribute for which a part must be extracted.

startIx: starting position in the character string.

endIx: ending position in the character string.

Replaced by a portion of the value (as a character string) of the attrib attribute, between the startIx position and endIx position.

Example: subString(name, 0, 5)

Replaced by the first five characters of the name attribute value. If this value is Montreal, the mouseover will display Montr.

encode(attrib, encoding)

attrib: the name of the attribute to code

encoding: the name of the encoding

Replaced by the value of the attrib attribute once it is encoded with the specified character encoding (UTF-8, CP437, ISO 8859-1, etc).

Example: encode(name, UTF-8)

Replaced by the value of the name attribute encoded in UTF-8 characters.

<script> code JavaScript </script>

Runs the JavaScript code found between the tags. In JavaScript, the attribute values of the elements are accessible through the elementValue() or ev() function.

Mathematical operations or character string operations can be performed on attribute values. To display content in the bubble, the script must call on the print() function.

Example: <script> print ( ev(population) / ev(area) ); </script>

Calculates and displays the result of the value of the population attribute divided by the value of the area attribute.

Example: <script>

var KM_IN_MI = 0.621371;

var dist_mi = ev(km) * KM_IN_MI;

print('ev(osm_name)');

print(dist_mi.toFixed(1) + " mi");

</script>

Converts the distance in kilometers contained in the value of the km attribute into miles. Displays the value of the osm_name attribute and the distance in miles with a decimal figure.

<a href="download:file URL">some text</a>

JMap supports a special hyperlink syntax that allows a user to download a file by clicking on the link. The file to download can come from a http: or a file: URL.

Example: <a href="download:http://someserver/123/report.pdf">Download</a>

Displays a link that can be used to download the report.pdf file from the web.

Example: <a href="download:file://D:/123/report.pdf">Download</a>

Displays a link that can be used to download the report.pdf file from a Windows file system folder.

City: ev(CITY)

(ev(COUNTRY))

Example containing static parts and displaying 2 attribute values on 2 lines.

<b>ev(STATION_NAME)</b>

<a href="ev(URL)">Site web</a>

An example of basic formatting using HTML tags and a hyperlink where the URL comes from the value of the URL attribute.

<b>ev(DESCRIPTION)</b>

<script>

var SQ_KM_IN_SQ_MI = 2.58998811;

var area_sq_mi = ev(AREA_KM2) / SQ_KM_IN_SQ_MI;

print(area_sq_mi.toFixed(1) + " sq. mi");

</script>

An example of a <script> tag with JavaScript code. The value of the AREA_KM2 attribute is converted from square kilometers to square miles.

table style="border:3px solid black; border-radius:5px; background: #1fc8db; color:white">

<tbody> <tr> <td class="">Gratton</td> <td class="actions">Bob</td> </tr> </tbody>

</table>

An example of formatting with a style attribute.

Mouseover locate example

Description

<a href="locate:region;-73;45;5;5">Locate</a>

Displays a Locate hyperlink. When clicked, locates the region defined by x=-73, y = 45, width = 5, height = 5 in the same map. This is expressed in the map's units.

<a href="locate:object;subway;name;'atwater'">Locate</a>

Displays a Locate hyperlink. When clicked, locates the elements on the subway layer that have their attribute name equal to atwater in the same map.

<a href="locate:object;subway;name;'a%'">Locate</a>

Displays a Locate hyperlink. When clicked, locates the elements on the subway layer that have their attribute name starting with letter a in the same map.

<a href="locate:object;subway;name;'atwater';1000">Locate</a>

Displays a Locate hyperlink. When clicked, locates the elements on the subway layer that have their attribute name equal to atwater in the same map. The resulting map has a scale of 1 : 1000.

<a href="locate:object;subway;name;'atwater':target=Result">Locate</a>

Displays a Locate hyperlink. When clicked, locates, in a new map called Result, the elements on the subway layer that have their attribute name equal to atwater. If a map called Result already exists, it is reused. If the name of the map was new, a new map (with an automatically generated name) would be created each time.
