// PUBLIC FORM HANDLER /* CONFIG the config is an array parsed into the html (head or body), with the following structure: public_form_config_%bid%[n] = ['data_key','data_value','field_label','field_id','field_type','field_required','validation_type','display_field','display_required','display_label','field_style','review_value']; KEY 0 'data_key' - the data key, used as key for sending information to server (like: "first_name") 1 'data_value' - the data value, used for sending back to server, if a value is provided, the field will be displayed with it (like: "Harry") 'value_type' - controls how the received value is treated, accepts 'real' or 'hint' (a hint value will be displayed in the field, then disappear when the field is clicked, while a real value will be editable) 6 'value_validate' - the type of validation used to verify the entered data (like: "email") 8 'value_validate_assist' - triggers associated typing assistant if there is one, accepts 1 5 'value_required' - makes correct input obligatory to complete the form, accepts 1 (like: a required checkbox must be checked to let the field validate) 11 'value_review' - this will show the input value again upon succesfully completing the form, accepts 1 13 'value_review_mask' - needs the tag #value# and is wrapped around the value for display in the completed part, (like: '#value#
' this is the default when nothing is specified) 4 'input_type' - the html field type (like: "checkbox") 3 'input_locked' - sets input field to read only, accepts 1 9 'input_class' - passes a string to the class attribute of the input, note that this can be a multiclass (like: "plain_text blue_background") 10 'input_style' - passes a string to the style attribute of the input tag (like: "width: 100px; font-size-: 14px;") 2 'label_content' - the form field label, a description of the field as provided by the server (like: "First name:") 12 'label_required_mask' - needs the tag #label# and is wrapped around the label, to alter the appearance of the label of required items 'label_rejected_mask' - needs the tag #label# and is wrapped around the label, to alter the appearance of the label of rejected items (like: make the text red) 7 'field_mask' - needs the tags #input# and #label#, omitting these tags in the mask code results in the label and/or input being hidden, not defining a field_mask results in a default mask '#label# #input#
' being used. NOTES FIELD TYPES text - a text box, can receive and return text checkbox - a checkbox, can be checked or unchecked, can receive and return either 1 or 0 VALIDATION TYPES note: some validation types have an associated typing-assistant that is active in the input field, the typing assistant helps prevent faulty input while the user is typing. email - checks for entry of a valid email address date - checks for entry of a valid date in the form of dd-mm-yyyy DATA KEYS the following keys in the form config have special meaning for the script: - public_form_bid -> a unique string parsed into the config and html, to let the handler find the right parts - public_form_btf -> the name of the file to send results to HTML COMPONENTS part id's (the html parts that get visually swapped while using the form, like 'starting info', 'user activity', 'ending info') note: if public_form_part_passive or public_form_part_completed is missing (not in the document) they will automatically be skipped note: if public_form_part_completed is missing, public_form_message_success in the active part will replace it public_form_part_passive public_form_part_active public_form_part_completed message id's (html blocks in the active part that get displayed to provide feedback while the user is working on the form) public_form_message_default public_form_message_rejected public_form_message_failure public_form_message_excess public_form_message_success data id's (the user entered data) public_form_data_readout_area field id's (span where the fields appear) public_form_fields_area debug id's (span where the debug info appears) public_form_debug_console */ function tvgs_typing_assistant(field_element,correction_type) { // validation types that are not known to this function will simply be ignored // date // allows typing of numbers and hyphen, max 10 chars if (correction_type == 'date') { // truncate if (field_element.value.length > 10) { field_element.value = field_element.value.substring(0,10); } // replace if (field_element.value.match(/[^-0-9]+/) != null || field_element.value.match(/-{2,}/) != null) { field_element.value = field_element.value.replace(/[^-0-9]+/g, '-').replace(/-{2,}/g, '-'); } } // email // allows typing of alphanumeric, hyphens, underscores, dots and at if (correction_type == 'email') { // replace while (field_element.value.match(/[^-._@0-9a-zA-Z]+/) != null) { field_element.value = field_element.value.replace(/[^-._@0-9a-zA-Z]+/g, ''); } /* // validate if(/^([a-zA-Z0-9_.-])+@([a-zA-Z0-9_.-])+\.([a-zA-Z]{2,6})+$/.test(input)) { //alert('good'); return true; } */ } // text-tags // allows typing of alphanumeric, hyphens, underscores, dots and at if (correction_type == 'text_tags') { // replace <> tags while (field_element.value.match(/<.+?>/) != null) { field_element.value = field_element.value.replace(/<.+?>/g, ''); } // replace [] tags while (field_element.value.match(/\[.+?\]/) != null) { field_element.value = field_element.value.replace(/\[.+?\]/g, ''); } /* // validate if(/^([a-zA-Z0-9_.-])+@([a-zA-Z0-9_.-])+\.([a-zA-Z]{2,6})+$/.test(input)) { //alert('good'); return true; } */ } /* if(/^[0-3]?[0-9] *[-\/] *[0-1]?[0-9] *[-\/] *[1-2][0-9]{3}$/.test(input)) { //alert('good'); return true; } else { //alert('bad'); return false; } */ } function checkEnter(e) { //e is event object passed from function invocation var characterCode; //literal character code will be stored in this variable if(e && e.which) { //if which property of event object is supported (NN4) e = e; characterCode = e.which; //character code is contained in NN4's which property } else { e = event; characterCode = e.keyCode; //character code is contained in IE's keyCode property } if(characterCode == 13) { //if generated character code is equal to ascii 13 (if enter key) //document.forms[0].submit() //submit the form return true; } else { return false; } } function tvgs_public_form_handler(public_form_config) { // get config values var config = eval(public_form_config); if (document.getElementById('sm_js_console')) document.getElementById('sm_js_console').innerHTML += 'Form handler: running form "public_form_config".
