For example, QML does -not provide a \c window object or \c{DOM API} as commonly found in a browser environment. - -\section1 Common Base - -Like a browser or server-side JavaScript environment, the QML runtime implements the -\l{ECMA-262}{ECMAScript Language Specification} standard. This provides access to -all of the built-in types and functions defined by the standard, such as Object, Array, and Math. -The QML runtime implements the 5th edition of the standard, which is the same edition commonly -implemented by browsers. - -The standard ECMAScript built-ins are not explicitly documented in the QML documentation. For more -information on their use, please refer to the ECMA-262 5th edition standard or one of the many online -JavaScript reference and tutorial sites, such as the \l{W3Schools JavaScript Reference} (JavaScript Objects -Reference section). Many sites focus on JavaScript in the browser, so in some cases you may need to double -check the specification to determine whether a given function or object is part of standard ECMAScript or -specific to the browser environment. In the case of the W3Schools link above, the \c{JavaScript Objects -Reference} section generally covers the standard, while the \c{Browser Objects Reference} and \c{HTML DOM -Objects Reference} sections are browser specific (and thus not applicable to QML). - -\section1 Host Objects and Functions - -The QML JavaScript host environment implements the following host objects and functions: - -\list -\li The \l{QmlGlobalQtObject}{Qt object}: This object is specific to QML, and provides helper methods - and properties specific to the QML environment. -\li qsTr(), qsTranslate(), qsTrId(), QT_TR_NOOP(), QT_TRANSLATE_NOOP(), and QT_TRID_NOOP() functions: - These functions are specific to QML, and provide \l{Translation}{translation capabilities} to the QML environment. -\li gc() function: This function is specific to QML, and provides a way to manually trigger garbage collection. -\li print() function: This function is specific to QML, and provides a simple way to output information to the console. -\li The \l{Console API}{console object}: This object implements a subset of the \l{http://getfirebug.com/wiki/index.php/Console_API}{FireBug Console API}. -\li \l{XMLHttpRequest}, DOMException: These objects implement a subset of the \l{http://www.w3.org/TR/XMLHttpRequest/}{W3C XMLHttpRequest specification}. -\endlist - -See \l{QML Global Object} for more details on these host objects and functions. - -\section1 Native Object Modification - -QML makes the following modifications to native objects: - -\list -\li An arg() function is added to the String prototype. -\li Locale-aware coversion functions are added to the \l{Date} and \l{Number} prototypes. -\endlist - -\section1 Restrictions - -QML implements the following restrictions for JavaScript code: - -\list -\li JavaScript code cannot modify the global object. -\li Global code is run in a reduced scope. -\li The value of \c this is undefined in QML in the majority of contexts. -\endlist - -See \l {QML JavaScript Restrictions} for more details on these restrictions. - -*/ |
