Need to restrict the document name length to 40 chars while uploading document in SharePoint library RRS feed

  • Question

  • hi,

    need to limit the length of the document name while uploading the document using the upload link button in library.

    i tried to apply JavaScript to do the same by linking it with CEWP but it didnt work.

    need to know the name of the property or function that i can use to call the upload document, so that i can validate the char length of the filename that i have selected to upload in the library.

    following is the js code i have used:

    <script type="text/javascript" language="javascript">

    var filename = document.getElementById('name').value;    

            alert("File name is too big. It should be less than 40 characters.");
                    return false;
                    alert("valid Format");
                    return true;

  • You may want to look at webhooks now. Using hooks you can write event handler and control the behavior.

  • Hi Falguniv,

    We can override the CheckAssetLibMediaExtension function in upload.aspx to check the file name length, the upload page is located at the path:

    C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\TEMPLATE\LAYOUTS\upload.aspx

    More information and the detailed steps, please refer the article below:
