This +includes drawing the autocompletion menu, observing keyboard +and mouse events, and similar. + +Specific autocompleters need to provide, at the very least, +a getUpdatedChoices function that will be invoked every time +the text inside the monitored textbox changes. This method +should get the text for which to provide autocompletion by +invoking this.getToken(), NOT by directly accessing +this.element.value. This is to allow incremental tokenized +autocompletion. Specific auto-completion logic (AJAX, etc) +belongs in getUpdatedChoices. + +Tokenized incremental autocompletion is enabled automatically +when an autocompleter is instantiated with the 'tokens' option +in the options parameter, e.g.: +new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' }); +will incrementally autocomplete with a comma as the token. +Additionally, ',' in the above example can be replaced with +a token array, e.g. { tokens: [',', '\n'] } which +enables autocompletion on multiple tokens. This is most +useful when one of the tokens is \n (a newline), as it +allows smart autocompletion after linebreaks. + +***/ + +MochiKit.Base.update(MochiKit.Base, { + ScriptFragment: '(?:<script.*?>)((\n|\r|.)*?)(?:<\/script>)', + +/** @id MochiKit.Base.stripScripts */ + stripScripts: function (str) { + return str.replace(new RegExp(MochiKit.Base.ScriptFragment, 'img'), ''); + }, + +/** @id MochiKit.Base.stripTags */ + stripTags: function(str) { + return str.replace(/<\/?[^>]+>/gi, ''); + }, + +/** @id MochiKit.Base.extractScripts */ + extractScripts: function (str) { + var matchAll = new RegExp(MochiKit.Base.ScriptFragment, 'img'); + var matchOne = new RegExp(MochiKit.Base.ScriptFragment, 'im'); + return MochiKit.Base.map(function (scriptTag) { + return (scriptTag.match(matchOne) || ['', ''])[1]; + }, str.match(matchAll) || []); + }, + +/** @id MochiKit.Base.evalScripts */ + evalScripts: function (str) { + return MochiKit.Base.map(function (scr) { + eval(scr); + }, MochiKit.Base.extractScripts(str)); + } +}); + +MochiKit.Form = { + +/** @id MochiKit.Form.serialize */ + serialize: function (form) { + var elements = MochiKit.Form.getElements(form); + var queryComponents = []; + + for (var i = 0; i < elements.length; i++) { + var queryComponent = MochiKit.Form.serializeElement(elements[i]); + if (queryComponent) { + queryComponents.push(queryComponent); + } + } + + return queryComponents.join('&'); + }, + +/** @id MochiKit.Form.getElements */ + getElements: function (form) { + form = MochiKit.DOM.getElement(form); + var elements = []; + + for (var tagName in MochiKit.Form.Serializers) { + var tagElements = form.getElementsByTagName(tagName); + for (var j = 0; j < tagElements.length; j++) { + elements.push(tagElements[j]); + } + } + return elements; + }, + +/** @id MochiKit.Form.serializeElement */ + serializeElement: function (element) { + element = MochiKit.DOM.getElement(element); + var method = element.tagName.toLowerCase(); + var parameter = MochiKit.Form.Serializers[method](element); + + if (parameter) { + var key = encodeURIComponent(parameter[0]); + if (key.length === 0) { + return; + } + + if (!(parameter[1] instanceof Array)) { + parameter[1] = [parameter[1]]; + } + + return parameter[1].map(function (value) { + return key + '=' + encodeURIComponent(value); + }).join('&'); + } + } +}; + +MochiKit.Form.Serializers = { + +/** @id MochiKit.Form.Serializers.input */ + input: function (element) { + switch (element.type.toLowerCase()) { + case 'submit': + case 'hidden': + case 'password': + case 'text': + return MochiKit.Form.Serializers.textarea(element); + case 'checkbox': + case 'radio': + return MochiKit.Form.Serializers.inputSelector(element); + } + return false; + }, + +/** @id MochiKit.Form.Serializers.inputSelector */ + inputSelector: function (element) { + if (element.checked) { + return [element.name, element.value]; + } + }, + +/** @id MochiKit.Form.Serializers.textarea */ + textarea: function (element) { + return [element.name, element.value]; + }, + +/** @id MochiKit.Form.Serializers.select */ + select: function (element) { + return MochiKit.Form.Serializers[element.type == 'select-one' ?
