From the jQuery documentation: you specify the asynchronous option to be false to get a synchronous Ajax request. Then your callback can set some data before your mother function proceeds.
Here's what your code would look like if changed as suggested:
beforecreate: function (node, targetNode, type, to) {
jQuery.ajax({
url: 'http://example.com/catalog/create/' + targetNode.id + '?name=' + encode(to.inp[0].value),
success: function (result) {
if (result.isOk == false) alert(result.message);
},
async: false
});
}
Update: June-2021
For a specific case when you need all query params:
const urlSearchParams = new URLSearchParams(window.location.search);
const params = Object.fromEntries(urlSearchParams.entries());
Update: Sep-2018
You can use URLSearchParams which is simple and has decent (but not complete) browser support.
const urlParams = new URLSearchParams(window.location.search);
const myParam = urlParams.get('myParam');

You don't need jQuery for that purpose. You can use just some pure JavaScript:
function getParameterByName(name, url = window.location.href) {
name = name.replace(/[\[\]]/g, '\\$&');
var regex = new RegExp('[?&]' + name + '(=([^&#]*)|&|#|$)'),
results = regex.exec(url);
if (!results) return null;
if (!results[2]) return '';
return decodeURIComponent(results[2].replace(/\+/g, ' '));
}
Usage:
// query string: ?foo=lorem&bar=&baz
var foo = getParameterByName('foo'); // "lorem"
var bar = getParameterByName('bar'); // "" (present with empty value)
var baz = getParameterByName('baz'); // "" (present with no value)
var qux = getParameterByName('qux'); // null (absent)
NOTE: If a parameter is present several times (?foo=lorem&foo=ipsum
), you will get the first value (lorem
). There is no standard about this and usages vary, see for example this question: Authoritative position of duplicate HTTP GET query keys.
NOTE: The function is case-sensitive. If you prefer case-insensitive parameter name, add 'i' modifier to RegExp
NOTE: If you're getting a no-useless-escape eslint error, you can replace name = name.replace(/[\[\]]/g, '\\$&');
with name = name.replace(/[[\]]/g, '\\$&')
.
This is an update based on the new URLSearchParams specs to achieve the same result more succinctly. See answer titled "URLSearchParams" below.

Yeah, if you want to search within content sources which are scripts used by extensions and the internal browser API, you enable it in the Settings of DevTools and then from any panel in DevTools you can type Ctrl + Shift + F or (on Mac) Options + Command + F (⌥⌘F) to search across all sources, snippets, and files.
Even more helpful to what you may be needing is to set up a Workspace in Settings cog which you can map to a local directory of files which will be available in the Sources file browser sidebar which will also be searchable with the above shortcut.
