Create dialog, set content and return value from component

I create in vm button

<input type="button" value="Change status" onClick="run()"/>

in js file i have

function run() {
        AJS.$(document).ready(function () {
            var popup = new AJS.Dialog(470, 250);
            popup.addButton("Ok", function (dialog) {
//get content
            popup.addCancel("Cancel", function (dialog) {
            }, "#");
            popup.addPanel("SinglePanel", getContentComment(), "singlePanel");

function getContentComment() {
    var str = "";
    str += "<textarea class='textarea' name='tag_name' id='tag_id' rows='8'></textarea>";
    return str;

and i want get text from text area.

it's doing in get content, i think, but how?

There are many opportunities to do that.

First, you have the "id" attribute in your input - just use it: AJS.$('#tag_id').val()!!

Second, you can add in AJS.Dialog constructor "id" property(look here), so when you need to get text from it's element it will be like this:

AJS.$('#example-dialog [name=tag_name]').val()

Next, to get dialog element you can use "popup.element" property

var dialog = new AJS.Dialog(100,100);
var text = AJS.$(dialog.popup.element).find('[name=tag_name]').val()

Also, you can pass in "addPanel" not only html code, but the selector of element to paste. so you can create somewhere

(your page html)
<div id="test"><textarea class='textarea' name='tag_name' rows='8'>/textarea></div>
popup.addPanel('SinglePanel', '#test', 'singlePanel');

and when you write AJS.$('#test [name=tag_name]').val() it works

Good luck!

Thanks! I have been trying to figure out why AJS.$('#comment').val() returns "" and after much fiddling in developer tools I almost gave up. This worked AJS.$('#comment-edit [name=comment]').val()
