Populating array of input fields as alternate fields using jQuery UI datepicker

- by Micor

I am using jquery ui datepicker in order to populate start and end dates for multiple events on the same page, the number of events is dynamic and I need to post day, month and year as separate fields, so I have something like this: <input type="text" name="event[0].startDate" class="date"/> <input type="hidden" name="event[0].startDate_day" class="startDate_day" /> <input type="hidden" name="event[0].startDate_month" class="startDate_month" /> <input type="hidden" name="event[0].startDate_year" class="startDate_year" /> <input type="text" name="event[0].endDate" class="date"/> <input type="hidden" name="event[0].endDate_day" class="endDate_day" /> <input type="hidden" name="event[0].endDate_month" class="endDate_month" /> <input type="hidden" name="event[0].endDate_year" class="startDate_year" /> event[1]... event[2]... I started working on jQuery functionality and this is what I have so far, which will populate alternate fields for startDate by class, of course it will not do what I need because I need to populate by field name rather then class: $(".date").datepicker({ onClose: function(dateText,picker) { $('.startDate_month').val( dateText.split(/\//)[0] ); $('.startDate_day').val( dateText.split(/\//)[1] ); $('.startDate_year').val( dateText.split(/\//)[2] ); }}); I need help figuring out how can I get the name of the input field within datepicker function so the alternate field assignment done by that field name + _day, month, year so this function can work for all the events on the page, making function above look more like: $(".date").datepicker({ onClose: function(dateText,picker) { $('input[' + $name + '_month' + ']').val( dateText.split(/\//)[0] ); $('input[' + $name + '_day' + ']').val( dateText.split(/\//)[1] ); $('input[' + $name + '_year' + ']').val( dateText.split(/\//)[2] ); }}); Hope that makes sense :) Thanks

Append indexed input fields with attached datepicker widget

- by Micor

I am looking for the most efficient way to add a set of fields with datepicker widget attached on click event. So here I have a set of indexed events being generated on a page: <div id="events"> <div class="event"> <input type="text" id="event_0_startDate" name="event[0].startDate" class="date"/> <input type="hidden" id="event_0_startDate_day" name="event[0].startDate_day" /> <input type="hidden" id="event_0_startDate_month" name="event[0].startDate_month" /> <input type="hidden" id="event_0_startDate_year" name="event[0].startDate_year"/> </div> <div class="event"> <input type="text" id="event_1_startDate" name="event[1].startDate" class="date"/> <input type="hidden" id="event_1_startDate_day" name="event[1].startDate_day" /> <input type="hidden" id="event_1_startDate_month" name="event[1].startDate_month" /> <input type="hidden" id="event_1_startDate_year" name="event[1].startDate_year" /> </div> .... more event divs .... </div> <a href="#" id="add_event">Add event</a> .. with datepicker widget attached: $(".date").datepicker({ onClose: function(dateText,picker) { var prefix = $(this).attr('id'); $('#' + prefix + '_month').val( dateText.split(/\//)[0] ); $('#' + prefix + '_day').val( dateText.split(/\//)[1] ); $('#' + prefix + '_year').val( dateText.split(/\//)[2] ); } }); I need a function that will add inside div id="events" after the last div class="event" another div class="event" where N is the next index and attach datepicker widget above to the new input field with class="date" like: <div class="event"> <input type="text" id="event_N_startDate" name="event[N].startDate" class="date"/> <input type="hidden" id="event_N_startDate_day" name="event[N].startDate_day"/> <input type="hidden" id="event_N_startDate_month" name="event[N].startDate_month" /> <input type="hidden" id="event_N_startDate_year" name="event[N].startDate_year" /> </div> Thank you.

Cloning and renaming form elements with jQuery

- by Micor

I am looking for an effective way to either clone/rename or re-create address fields to offer ability to submit multiple addresses on the same page. So with form example like this: <div id="addresses"> <div class="address"> <input type="text" name="address[0].street"> <input type="text" name="address[0].city"> <input type="text" name="address[0].zip"> <input type="text" name="address[0].state"> </div> </div> <a href="" id="add_address">Add address form</a> From what I can understand there are two options to do that: Recreate the form field by field and increment the index which is kind of verbose: var index = $(".address").length; $('<`input`>').attr({ name: 'address[' + index + '].street', type: 'text' }).appendTo(...); $('<`input`>').attr({ name: 'address[' + index + '].city', type: 'text' }).appendTo(...); $('<`input`>').attr({ name: 'address[' + index + '].zip', type: 'text' }).appendTo(...); $('<`input`>').attr({ name: 'address[' + index + '].state', type: 'text' }).appendTo(...); Clone Existing layer and replace the name in the clone: $("div.address").clone().appendTo($("#addresses")); Which one do you recommend using in terms of being more efficient and if its #2 can you please suggest how I would go about search and replacing all occurrences of [0] with [1] ([n]). Thank you.

Re-using jQuery widgets

- by Micor

I am looking for a most efficient way to re-use widgets with different selectors... For example if I have: $("#selector1").datepicker({ beforeShow: function(var1,var2) { // do stuff }, onClose: function(var1,var2) { // do stuff }, onSelect: function(var1,var2) { // do stuff } }) And later I am looking to assign this same widget with same functions inside to other selectors which are not known at load time. Since its not about choosing a better selector and I want to avoid: $("#new-selector2").datepicker({ beforeShow: function(var1,var2) { // do stuff }, onClose: function(var1,var2) { // do stuff }, onSelect: function(var1,var2) { // do stuff } }) $("#new-selector3").datepicker({ beforeShow: function(var1,var2) { // do stuff }, onClose: function(var1,var2) { // do stuff }, onSelect: function(var1,var2) { // do stuff } }) What would be the best way of doing something like: var reusableDatepicker = datepicker({ beforeShow: function(var1,var2) { // do stuff }, onClose: function(var1,var2) { // do stuff }, onSelect: function(var1,var2) { // do stuff } }) $("#selector1").attach(reusableDatepicker); $("#new-selector2").attach(reusableDatepicker); $("#new-selector3").attach(reusableDatepicker); I know it has to be obvious to all jQuery devs out there, so obvious I cannot find it in docs :) Thank you!

hasErrors with indexed property

- by Micor

I am having hard time getting hasErrors to work with indexed properties. For example class Order { String prop1 String prop2 static hasMany = [items: Item] } class Item { String name static constraints = { name(blank:false) } } Validation works properly and on item.name being blank I do get an error with <g:renderErrors bean="${orderInstance}"/> However, I am trying to have input box highlighted using hasErrors : <g:each in="${orderIntsance.items}" status="i" var="item"> <span class="field ${hasErrors(bean: orderInstance, field: ????????? , 'errors')}"> <g:textField name="items[${i}].name" value="${item?.name}"/> </span> </g:each> Not sure how to get to it with a field: property, any ideas? Thanks

Create comma separated string from 2 lists the groovy way

- by Micor

What I have so far is: def imageColumns = ["products_image", "procuts_subimage1", "products_subimage2", "prodcuts_subimage3", "products_subimage4"] def imageValues = ["1.jpg","2.jpg","3.jpg"] def imageColumnsValues = [] // only care for columns with values imageValues.eachWithIndex { image,i -> imageColumnsValues << "${imageColumns[i]} = '${image}'" } println imageColumnValuePair.join(", ") It works but I think it could be better. Wish there was a collectWithIndex ... Any suggestions?
