    <p>I have a jQuery function with several nested ajax calls:</p> <pre><code>function ulozitKlienta () { //some code if (!confirm("Není vyplněno datum vstupu klienta!\n\nPřesto uložit?")) return false; $.ajax({ type : "POST", cache : false, url : "ajax/ulozit_klienta.php", data : JSON.stringify(out), dataType: "json", success : function (data) { if (data.vysledek == "chyba") { //some code return false; // TODO ajax return } else { if (out["akce"] == "pridat") { if (data.vysledek == "duplikat") { $("#js-d-duplikat").dialog({ modal : true, buttons : { "Přesto vytvořit nového" : function () { out["opravdu"] = true; $.ajax({ type : "POST", cache : false, url : "ajax/ulozit_klienta.php", data : JSON.stringify(out), dataType: "json", success : function (data) { if (data.vysledek == "chyba") { //some code return false; // TODO ajax return } else //some code }, error : function (data, status, e) { //some code return false; // TODO ajax return } }); } } }); } else //some code } else //some code } }, error : function (data, status, e) { //some code return false; // TODO ajax return } }); } </code></pre> <p>I have it in function because I call it from two different points elsewhere:</p> <pre><code>$("#add_tab").on("click", function() { // založí nový protokol a vytvoří mu tab if (!ulozitKlienta()) return false; //some code }); $("#menu_local").on("click", "[name='ulozit_klienta']", function() { ulozitKlienta(); }); </code></pre> <p>My problem is, that function ulozitKlienta is not waiting for ajax calls to end and is returning undefined. I thought I use Promise interface as showed here <a href="https://stackoverflow.com/a/11283748/836697">https://stackoverflow.com/a/11283748/836697</a> but I really don't know how.</p>

    3. COI can't use none of the provided answers. async:false is out of question. And using callbacks or promises as shown is not suitable for my case. I need to **define, NOT immediately use** the function once and use it at two different points in code which happen to be in .on(), so they're called based on interaction. I strongly believe that promises is the right way, I just don't know HOW.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
