How to get values of jQuery Tags Input plugin

I use this jQuery Tags Input plugin:

jQuery Tags Input

but I can't get the values on my ph开发者_高级运维p file.

If you are trying to get the individual values using jQuery you can use: (This is assuming the text input you made into a tag input has an id of "keywords")

$('#keywords').tagsInput({  
    'height':'auto',  
    'width':'350px',
    'defaultText':'',
    'delimiter': '|'
});
/*The delimiter option above overrides the default comma delimiter in the plugin allowing commas in tags if you prefer that...*/

var $keywords = $("#keywords").siblings(".tagsinput").children(".tag");  
var tags = [];  
for (var i = $keywords.length; i--;) {  
    tags.push($($keywords[i]).text().substring(0, $($keywords[i]).text().length -  1).trim());  
}  

/*Then if you only want the unique tags entered:*/  
var uniqueTags = $.unique(tags);  
alert(uniqueTags.toSource());

To get the list of emails from:

<input type="text" name="to_addresses" class="to_addresses" data-role="tagsinput" >

I use:

$emails = []
$.map($(".tagsinput span span"),function(e,i){
$emails.push($(e).text().trim());
})

Works for me, thought I'd share it.

 $("#btn").click(function () {
         var $tagWord = $("#tags_2").siblings(".tagsinput").children(".tag");
         var tags = [];
         for (var i = $tagWord.length; i--; ) {
             tags.push($($tagWord[i]).text().substring(0, $($tagWord[i]).text().length - 1).trim());
         }

         /*Then if you only want the unique tags entered:*/
         var uqTags = $.unique(tags);
         alert(uqTags.toSource());

     });

---

using jquery you can do it in one line:

$.map($('.tag span'),function(e,i){return $(e).text().trim();})

---

$("input").tagsinput('items')   

["Amsterdam","Washington","Sydney","Beijing","Cairo"]

$("input").val()    

"Amsterdam,Washington,Sydney,Beijing,Cairo"

---

can you provide an example of what is POSTed? you can do so by pointing your form to go to api.fatherstorm.com?query and copying the json data that it gives you

---

it change the hidden input value, and will post the data when you click submit , you can test it by a simple php script. print_r($_POST) to see it.

---

Based on sagivo answer you can write a function like this :

function getKeywords() {
  return $.map($('.tag span'),function(e,i){
    return $(e).text().trim();
  });
}

That will return an array of keywords present in the input. Like this [ "there", "it", "is" ]
