I tried to put a textarea inside a dialog box and what I want is to get the value of that textarea if "ok" is click but I can't get the value. What might be the problem?
$(document).on('click', '#open', function () { var txt = $('#txt').val(); $('#break-diag').dialog({ modal: true, title: 'Dialog', show: { effect: "scale", duration: 200 }, resizable: false, buttons: [{ text: "ok", click: function () { console.log(txt); } }] }); });
#break-diag{ display:none; }

You are capturing the textarea value on click of open; which would be empty during this event.
The value should be captured on click of Ok
click: function () {
var txt = $('#txt').val();
console.log(txt);
}
You're trying to get the text when the dialogue opens. There's no text there, yet.
$(document).on('click', '#open', function () { $('#break-diag').dialog({ modal: true, title: 'Dialog', show: { effect: "scale", duration: 200 }, resizable: false, buttons: [{ text: "ok", click: function () { var txt = $('#txt').val(); console.log(txt); } }] }); });
#break-diag{ display:none; }

$(document).on('click', '#open', function () {
$('#break-diag').dialog({
modal: true,
title: 'Dialog',
show: {
effect: "scale",
duration: 200
},
resizable: false,
buttons: [{
text: "ok",
click: function () {
var text= $('#txt').val();
alert(text);
}
}]
});
});
You set the CSS style display:none with #break-diag DIV.
so how can you imagine that anything can be display.
so when you click on the button, display:none property should be removed from #break-diag DIV .
