Execute Code to save madatory fields when Cancel button is selected in the editform.aspx

Question

After a user uploads a document the editform.aspx page is displayed. I need to force an update even if Cancel button is selected within the default editform.aspx form of a library. I know there is a preSaveAction function for save, is there a preCancelAction I can call to execute additional code on a cancel? Has anyone tried to force additional code to run even if the user selects cancel button within the default editform? Do i have to maybe capture that buttons event? What is that event? I have been searching and nothing found that matches what I want to do. I have successfully populated custom fields on the form so when the user selects save all is saved but when a user selects cancels i need some of the fields to still store the information. I tried and wrote code to do the save when the editform loads and it works great, but then if the user selects save i get error that the file is already updated by user. so i only want the code to run if i hit Cancel. Help!!!

<script type="text/javascript">

$(window).load(function(){
    try
    {
        // set custom fields on form so when user selects Save button these values are saved.  works great.

    // I can also save the items here as well using code below and when i select cancel they are saved.
    // but when I select save button I get an already saved error...  so i moved to only when hit cancel button below.

    }catch(ex)
    {
        alert(ex.toString());
    }

});



$(document).ready(function(){
    $(":button[value='Cancel']").click(function(){
    var context = SP.clientContext.get_current();
    var web = context.get_web();
    var listId = _spPageContextInfo.pageListId;
    var itemId = parseInt(GetUrlKeyValue('ID'));

    var list = web.get_lists().getById(listId);
    var listItem = list.getItemById(itemId);

    var urlValue = new SP.FieldUrlValue();
    urlValue.set_url(url);
    urlValue.det_description(descValue);

    listItem.set_item('Action',urlValue);
    listItem.set_item('ActionId',descValue);

    listItem.update();
    context.ExecuteQuery();

    });
});

</script>

Solution 1:

Use default values. So the values would store even if the user clicks the cancel button. This would work if the user closes the browser or terminate the web browser process. Please note this solution will not work for field types where setting default values is not available like "Person or Group".

Solution 2

Capture the cancel button's click event as @Dylan said and call the PreSaveAction

<script type="text/javascript">
$(document).ready(function(){
    $(":button[value='Cancel']").click(function(){
        saveFormFields();
    });
});
function saveFormFields()
{
    //set field values
}   
</script>
