    <p>If I make an ajax call, I can add success handling. I want to add similar logic to my custom functions.</p> <p>I have 6-10 custom functions that MUST be run sequentially or independently. They don't typically run independently so I have them daisy-chained now by calling the next function at the end of the previous but that is messy to read and does not allow for separate execution.</p> <p>I would love to have something like this:</p> <pre><code>function runall(){ runfirst().success( runsecond().success( runthird() )) } </code></pre> <p>I have had other situations were I would like to add <code>.success()</code> handling to a custom function, but this situation made it more important.</p> <p>If there is another way to force 6-10 functions to run synchronously, that could solve this problem, but I would also like to know how to add success handling to my custom functions.</p> <h3>I tried the following based on @lanzz's suggestion:</h3> <p>I added <code>.then()</code> to my function(s): </p> <pre><code>$bomImport.updateGridRow(rowId).then(function () { $bomImport.toggleSubGrid(rowId, false); }); var $bomImport = { updateGridRow: function (rowId) { $('#' + rowId + ' td[aria-describedby="bomImport_rev"]').html($("#mxRevTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_itemno"]').html($("#itemNoTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_used"]').html($("#usedTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_partSource"]').html($("#partSourceTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_partClass"]').html($("#partClassTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_partType"]').html($("#partTypeTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_partno"]').html($("#mxPnTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_descript"]').html($("#descTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_qty"]').html($("#qtyTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_custPartNo"]').html($("#custPartNoTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_crev"]').html($("#custRevTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_u_of_m"]').html($("#uomTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_warehouse"]').html($("#warehouseTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_standardCost"]').html($("#stdCostTxt").val()); $('#' + rowId + ' td[aria-describedby="bomImport_workCenter"]').html($("#wcTxt").val()); var defferred = new $.Deferred(); return defferred.promise(); }}; </code></pre> <p>The code correctly goes to the end of updateGridRow, gives no errors, but never gets back to call the second function.</p> <p>I also tried the following as was suggested @Anand:</p> <pre><code>workSheetSaveExit(rowId, isNew).save().updateRow().toggle(); function workSheetSaveExit(){ this.queue = new Queue; var self = this; self.queue.flush(this); } workSheetSaveExit.prototype = { save: function () { this.queue.add(function (self) { $bomImport.workSheetSave(rowId, isNew); }); return this; }, updateRow: function () { this.queue.add(function (self) { $bomImport.updateGridRow(rowId); }); return this; }, toggle: function () { this.queue.add(function (self) { $bomImport.toggleSubGrid(rowId, false); }); return this; } }; </code></pre> <p>Which didn't work.</p> <p><strong>Final Solution</strong><br/> For a great explanation of how to use deferred and make this work see here: <a href="http://www.erichynds.com/jquery/using-deferreds-in-jquery/" rel="nofollow">Using Deferred in jQuery</a></p>

    2. COFor some reason, those do not work. I think the issue is my function is not a jquery function. I call it like this:$bomImport.getWorksheet(); when I add .then, or .done, etc it does not have that method

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
