在textarea更改 - ajax帖子

Question

I have text area. Textarea Content arising from nestable list serealized process. Textarea content is like: [{"id":1,"children":[{"id":4}]},{"id":2}]

Text area:

 <div class="span6">
    <h3>Serialised Output (per list)</h3>
    <textarea id="nestable_list_1_output" class="m-wrap span12"></textarea>
 </div>

Also i have one jquery function:

$(function() { 

function conv(data){
var result=[];
function dfs(node, parent) {
    for(var i in node){
        result.push({id:node[i].id,pid:parent});
        if (node[i]['children']) dfs(node[i]['children'],node[i]['id']);
    }
}
dfs(data, 0);
return result;
}

I want make ajax post every time when values on texarea ​​are changed.

var data     = JSON.stringify(conv($.parseJSON($("textarea#nestable_list_1_output").val())));

$.ajax({
  type: 'POST',
  url: "http://example.com/navigation/save_menu",
  data: 'menu_data=' + JSON.stringify(data),
  dataType: 'json',
  success: console.log('Data Post:' + data),

});
How to do that? Many thanks for responses. Karlis.

Answer 1

You would create a change event:

$("#nestable_list_1_output").change(function() {
    var currentText = this.value;
    //AJAX TIME
});

Answer 2

Try this,

$("#textarea").on('keyup paste', function(e) {
    clearTimeout($(this).data('timeout'));
    $(this).data('timeout', setTimeout(function(){
        alert(e.target.value);
    }, 200));
});

EXAMPLE

This should even work in case of copy paste from keyboard and from mouse
