I've a jsp page with a form and some jquery code. Jquery code works perfectly, but if I return that page in a popup window by using an ajax call, the jquery code doesn't work any more.
I tried also to use delegation, that is:
$('select[name=myElementName]').on("change", function() {
// some code
});
or
$(document).on("change", 'select[name=myElementName]', function() {
// some code
});
instead of
$('select[name=myElementName]').change(function() {
// some code
});
Ajax call:
var preview = function () {
$.ajax({
type: "POST",
url: myAction.do,
data: "id=" + myid,
success: function (response) {
// some code
var x=window.open('', '_blank', 'titlebar=no,scrollbars=yes,menubar=no,height='+height+',width='+width+',resizable=yes,toolbar=no,location=no,location=0,status=no,left='+left+',top='+top+'');
x.document.open();
x.focus();
x.document.write(response);
return false;
},
error: function () {
return false;
},
});
};
EDIT
On Firefox 26.0 and Chrome 32.0.x, I resolved by using
x.document.close();
after
x.document.write(replace);
Instead, on IE, all the .js included scripts are ignored (for example the jquery-ui-1.9.1.js).
EDIT 2
I resolved with
<body onload="myload()">
and in my jsp I've myload() definition in which I call the scripts.
It is because you are creating new DOM structure but it doesn't have the event handlers attached. The easiest way is to run the event handler in the ajax callback:
$.ajax({
...
success: function (response) {
// some code
var x=window.open('', '_blank', 'titlebar=no,scrollbars=yes,menubar=no,height='+height+',width='+width+',resizable=yes,toolbar=no,location=no,location=0,status=no,left='+left+',top='+top+'');
x.document.open();
x.focus();
x.document.write(response);
// now, place the event handler here
$('select[name=myElementName]', x.document.body).change(function() {
// some code
});
}
});
Don't use document.write it completely overwrites whatever is on the page at the time of writing and leads to race conditions (e.g. the external scripts might have already been loaded, but they also might not, leading to unknown order of the write and script loads). Also, I believe documnt.write is putting serialized text into the document, not DOM objects so it may not trigger events.
Instead, you can open the new window and then manipulate the DOM objects there directly (assuming it's on the same server as your main page):
//Open a new window for the success info
var newWindow = window.open(newUrl);
//Now grab some element
var someItem = newWindow.document.getElementById( "someId");
//Manipulate dom either by "someItem.innerHTML" or "someItem.appendChild(...)"
If you are calling an AJAX server routine and putting the entire response w/o processing it on the client in to a new window, why not opening the window directly with the URL of that AJAX routine and skipping all stuff:
....
var x=window.open(myAction.do + "?id=" + myid,
'_blank',
'titlebar=no,scrollbars=yes,menubar=no,height='+height+',width='+width+',resizable=yes,toolbar=no,location=no,location=0,status=no,left='+left+',top='+top+'');
....
The only diff here is, that the request is a GET and not a POST request, but the data is just one id, which is acceptable, probably?
I had a similar problem in on of my projects. I solved it by writing a success method after the ajax call.
{
$.ajax({
type: "POST",
url: "/abc/",
data:{<data>},
async:false,
dataType:'json',
success: function(response)
{
success=1;
Id=response;
return;
}
});
if (success)
{
#your code here
var a='/xyz/?Id='+Id
window.open(a,'_blank');
window.location.href='/registration/'
}
return false;}
instead of using document.write, try fetching your success data(records arrived in success function) in a hidden DIV and clone it into your popup that should work
