For one of the requirements, I am working with SharePoint online and part of that, I would like to check if a choice column is empty or not using JSOM. Can someone please help me with the code. If a choice column is empty then I would like to restrict the user to perform Save/Upload in a SharePoint document library and show some message that user needs to fill out these fields. There are about 3 choice columns which I would like to validate if they are empty or not.Only and only if all three of them are non- empty then user can do upload or save in a document library. So this code will be added to the edit form of a Sp library.

I have 3 content types in the library, out of which one of those have these three columns so I would want to make sure that validation check only occurs for these 3 columns that are part of a content type, let's say test.

Thanks in advance.

Hi you can use PreSaveAction function to validate the item. 

 $(document).ready(function() { ProducerReferral(); attachEventHandlers(); // function for checking the duplication of files $('input[value=Save]').click(function() { PreSaveTest(); }); }); function PreSaveTest() { PreSaveAction(); } function PreSaveAction() { if ($("#idAttachmentsRow").css("display") == "none") { $("#part1 > h4")[1].innerHTML += "<span style='margin-left: 40px;' class='ms-formvalidation ms-csrformvalidation'>Please Attach Files.</span>"; returnVal = false; } else { return true; } }

Or 

 <script type="text/javascript"> var $j = jQuery.noConflict(); function PreSaveAction() { alert("here"); var txtStatus = $j(":input[title='Status']").val(); if(txtStatus == "In Progress"){ alert("Invalid Status"); var statusfocus = $j(":input[title='Status']"); statusfocus .focus(); return false;} return true; } </script>

Refer PreSaveAction

All the best !!!!

  • Hello Shridhar, i can not make them required since I want the other functionality to work and it depends on columns being non-mandatory and which is why I need to know what would be the JS approach, thanks. Commented May 15, 2018 at 19:06
