Im using the jQuery taggd plugin, so far so good.
I modified a small bit, im using it in edit mode. So when a user types in a value in the textbox it checks if it is a URL or or string, if its a URL it runs a ajax call to a php file which scrapes some data from the url. Url title, description and image. I have created 3 hidden input fields which get populated once the ajax call is finished. Once you click on the SAVE icon it saves the data to the DOM. But i want it to display again once a user clicks on the tag again. At the moment its only displaying the value of the standard input field.
This is the taggd plugin with some small modifications:

I thought this would do what i want, since it works with the standard text input box, using .val($e.text()), works fine but as soon as i do the same to the url_title box, for example .val($e.url_title()), i get the error below.
$input = $('<input id="url" type="text" size="16" />')
.val($e.text()),
$url_title = $('<input type="text" id="url_title" class="url_title" />'),
$button_ok = $('<button />')
.html(_this.options.strings.save),
$url_description = $('<input type="text" class="url_description" id="url_description" />'),
$url_image = $('<input type="text" class="url_img" id="url_img" />'),
$url_preview = $('<div id="content"></div>'),
$button_delete = $('<button />')
.html(_this.options.strings.delete);
But if for example i change the $url_title to
$url_title = $('<input type="text" id="url_title" class="url_title" />').val($e.url_title()),
I get a error back in the console:
Uncaught TypeError: undefined is not a function
This is the init code on the main page:

I hope someone can shine a light on it and point me in the right direction of what i'm doing wrong.
To simplify it, i want to be able to have a title input and a description input for my tags, how would i achieve this?
Thank you.
I suspect $e.url_title() is causing the error, as far as I know, url_title() isn't a method you can call on jQuery instances.
Presumably you meant to access a variable instead.
I couldn’t find an issue in your scripts, other than the undefined function call, so I basically rewrote the whole thing myself, which seems to work: http://jsbin.com/nexujuhefo/2/edit?js,console,output
I think the problem is Taggd weird logic ;)
Fields now remember data: http://jsbin.com/hosipiyuqa/1/edit?js,console,output
The question is very simple but also a bit theoretical.
Let's imagine you have a long JQuery script which modifies and animate the graphics of the web site. It's objective is to handle the UI. The UI has to be responsive so the real need for this JQuery is to mix some state of visualization (sportlist visible / not visible) with some need due to Responsive UI.
Thinking from an MVC / AngularJS point of view. How should a programmer handle that?
How to refactor JS / JQuery code to implement separation of concerns described by MVC / AngularJS?
I provide an example of JQuery code to speak over something concrete.

My steps in such cases are:
First of all write (at least) one controller
Replace all eventhandler with ng-directives (ng-click most of all)
Pull the view state out of the controller with ng-style and ng-class. In most of all cases ng-show and ng-hide will be sufficed
If there is code that will be used more than once, consider writing a directive.
And code that has nothing todo with the view state - put the code in a service
write unit tests (i guess there is no one until now:) )
I'm using the FoxyComplete plugin with Jquery Auto-Complete to do a simple search. Everything is setup and working great but I'm finding the search results extremely limiting.
I use a big JSON file for all of my data and the problem I'm having is in the following case: Let's assume that my JSON file has the following description:
{
"title": "Brand new black car"
},
If a user searches "black car", he or she will get the result perfectly and the search is great. BUT, if a user search "car new", nothing comes up even though both keywords are in my JSON file.
Any help would be great. I poured through the Jquery AutoComplete docs and couldn't find a solution either. My Jquery autocomplete js is below:
;
(function ($) {
$.fn.extend({

does anyone can show me how can i call the methods add_tags() and remove_tags() ?
thanks
$("selector").tagfield({remove:someobject});
$("selector").tagfield({add:someobject});
but the "remove" thing will not work i think, since the second "if" in fn.tagfield watches for "options.remove" but removes the "options.add" ...
I have been using the HTML 5 placeholder and just realised that it does not work outside HTML5 devices. As you can see by the code below the placeholder is always in lowercase and the value is always in upper case.
#maphead input::-webkit-input-placeholder {
text-transform:lowercase;
}
#maphead input:-moz-placeholder {
text-transform:lowercase;
}
<input id="start" type="text" spellcheck="false" placeholder="enter your post code" style="text-transform:uppercase;" class="capital"/>
This is all fine except when dealing with non HTML 5 devices. For this I have employed a bastardised bit of javascript.
function activatePlaceholders() {
var detect = navigator.userAgent.toLowerCase();
if (detect.indexOf("safari") > 0) return false;
var inputs = document.getElementsByTagName("input");
for (var i=0;i<inputs.length;i++) {
if (inputs[i].getAttribute("type") == "text") {
var placeholder = inputs[i].getAttribute("placeholder");
if (placeholder.length > 0 || value == placeholder) {
inputs[i].value = placeholder;
inputs[i].onclick = function() {
if (this.value == this.getAttribute("placeholder")) {
this.value = "";
}
return false;
}
inputs[i].onblur = function() {
if (this.value.length < 1) {
this.value = this.getAttribute("placeholder");
$('.capital').each(function() {
var current = $(this).val();
var place = $(this).attr('placeholder');
if (current == place) {
$(this).css('text-transform','lowercase')
}
});
}
}
}
}
}
}
window.onload = function() {
activatePlaceholders();
}
Firstly this Javascript is rancid. There must be an easier JQuery way. Now although this above does work (reasonably) it does not respond to keeping the placeholder in lowercase and the value in uppercase since it sets the value with the placeholder.
I've set you all up with a nice Fiddle http://jsfiddle.net/Z9YLZ/1/
Try something like this:
$(function() {
$('input[type="text"]').each(function () {
$(this).focus(function () {
if ($(this).attr('value') === $(this).attr('placeholder')) {
$(this).css('text-transform','lowercase');
$(this).attr('value', '');
}
}).blur(function () {
if ($(this).attr('value') === '') {
$(this).css('text-transform','uppercase');
$(this).attr('value', $(this).attr('placeholder'));
}
}).blur();
});
});
Edit: Explicitly declare the text-transform to cascade properly.
Try this one, I'm using it for a while and it works perfectly:
(function($, undefined) {
var input = document.createElement('input');
if ('placeholder' in input) {
$.fn.hinttext = $.hinttext = $.noop;
$.hinttext.defaults = {};
delete input;
return;
}
delete input;
var boundTo = {},
expando = +new Date + Math.random() * 100000 << 1,
prefix = 'ht_',
dataName = 'hinttext';
$.fn.hinttext = function(options) {
if (options == 'refresh') {
return $(this).each(function() {
if ($(this).data(dataName) != null) {
focusout.call(this);
}
});
}
options = $.extend({}, $.hinttext.defaults, options);
if (!(options.inputClass in boundTo)) {
$('.' + options.inputClass)
.live('focusin click', function() {
$($(this).data(dataName)).hide();
})
.live('focusout', focusout);
boundTo[options.inputClass] = true;
}
return $(this).each(function(){
var input = $(this),
placeholder = input.attr('placeholder');
if (placeholder && input.data(dataName) === undefined) {
var input_id = input.attr('id'),
label_id = prefix + expando++;
if (!input_id) {
input.attr('id', input_id = prefix + expando++);
}
$('<label/>')
.hide()
.css('position', options.labelPosition)
.addClass(options.labelClass)
.text(placeholder)
.attr('for', input_id)
.attr('id', label_id)
.insertAfter(input);
input
.data(dataName, '#' + label_id)
.addClass(options.inputClass)
.change(function() {
focusout.call(this);
});
}
focusout.call(this);
});
};
$.hinttext = function(selector, options) {
if (typeof selector != 'string') {
options = selector;
selector = 'input[placeholder],textarea[placeholder]';
}
$(selector).hinttext(options);
return $;
};
$.hinttext.defaults = {
labelClass: 'placeholder',
inputClass: 'placeholder',
labelPosition: 'absolute'
};
function focusout() {
var input = $(this),
pos = input.position();
$(input.data(dataName)).css({
left: pos.left + 'px',
top: pos.top + 'px',
width: input.width() + 'px',
height: input.height() + 'px'
})
.text(input.attr('placeholder'))
[['show', 'hide'][!!input.val().length * 1]]();
}
$($.hinttext);
})(jQuery);
You just need to make sure to style label.placeholder with CSS to look the same as HTML5 placeholder text (color: #999)

Bit late but here's what I do. Store all the default values on page load and then clear value text ONLY when it's the default value that is clicked on. This prevents the JS clearing user entered text.
jQuery(document).ready(function($){
var x = 0; // count for array length
$("input.placeholder").each(function(){
x++; //incrementing array length
});
var _values = new Array(x); //create array to hold default values
x = 0; // reset counter to loop through array
$("input.placeholder").each(function(){ // for each input element
x++;
var default_value = $(this).val(); // get default value.
_values[x] = default_value; // create new array item with default value
});
var current_value; // create global current_value variable
$('input.placeholder').focus(function(){
current_value = $(this).val(); // set current value
var is_default = _values.indexOf(current_value); // is current value is also default value
if(is_default > -1){ //i.e false
$(this).val(''); // clear value
}
});
$('input.placeholder').focusout(function(){
if( $(this).val() == ''){ //if it is empty...
$(this).val(current_value); //re populate with global current value
}
});
});
