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:
$(document).ready(function() {
var options = {
edit: true,
align: {
y: 'top'
},
offset: {
top: 15
},
handlers: {
//mouseenter: 'show',
click: 'toggle'
}
};
/*var data = [

{ x: 0.51, y: 0.5, text: 'Bird' },
{ x: 0.40, y: 0.3, text: 'Water, obviously' }
];*/
var data = [];
var taggd = $('.taggd').taggd( options, data );
taggd.on('change', function() {
console.log(taggd.data);
});
});
In the console log it logs the values fine:
[Object]0: Objecttext: "http://ift.tt/gbk8l4"url: "http://ift.tt/gbk8l4"url_description: "Q&A for professional and enthusiast programmers"url_image: "http://ift.tt/1HGxN5r"url_title: "Stack Overflow"x: 0.41141586360266863y: 0.19444444444444445
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.
