Delete Button with jslink to delete related item

[Douglenator83]

Hello,

i got a little problem to delete items with jslink in an related items list.

Thats my jslink code:

Code: Select all

(function () {
    function view(ctx, field) {
        // Get the markup that is by default rendered for the "Edit" field.
        var editButtonHtml = (new ComputedFieldRenderer(field.Name)).RenderField(
            ctx, field, ctx.CurrentItem, ctx.ListSchema);
        if (editButtonHtml.replace(/ /gi,'')) {
            // If the edit button is displayed, it means that the user has edit permissions. 
            // Then display a delete button also.
            var deleteButtonHtml =
                "<a href='#' title='Delete'><img src='/_layouts/15/images/delitem.gif' " +
                "onclick='javascript:window.deleteItem(\"" + ctx.ListTitle + "\",this);'/></a>";
                return editButtonHtml + "&nbsp;&nbsp;" + deleteButtonHtml;
        }
        return editButtonHtml;
    }
    var overrideCtx = {};
    overrideCtx.Templates = {};
    overrideCtx.Templates.Fields = {
        'Edit': {
            'View': view
         }
    };
    SPClientTemplates.TemplateManager.RegisterTemplateOverrides(overrideCtx);
})();

window.deleteItem = function (listName, element) {
    if (DeleteItemConfirmation()) {
        // Extract the id of the clicked list item.
        var id = $(element).closest("tr[iid]").attr("iid").split(',')[1];
        $.ajax({
            url: window._spPageContextInfo.webServerRelativeUrl +
                "/_api/web/lists/getbytitle('" + listName + "')/items(" + id + ")",
            type: "POST",
            headers: {
                "ACCEPT":"application/json;odata=verbose",
                "content-type":"application/json;odata=verbose",
                "X-RequestDigest": $("#__REQUESTDIGEST").val(),
                "IF-MATCH":"*",
                "X-HTTP-Method":"DELETE"
            },
            success: function(data) {
                $(element).closest("tr[iid]").remove();
            },
            error: function(error) {
                console.log(JSON.stringify(error));
            }
        });
    }
}

The code works fine in the listview but not not in any form.

I get the following error:

on this line of code

Code: Select all

   if (DeleteItemConfirmation()) {
        // Extract the id of the clicked list item.
        var id = $(element).closest("tr[iid]").attr("iid").split(',')[1];

Script error: object expected

Can u help me plz?

Dear Douglenator,
Unfortunately, JS Link is not supported on any custom forms, either ours or created with SharePoint designer.

[Douglenator83]

Is there any other way to do this ?
The easiest workaround would be a delete checkbox to delete files...
but i think this is not a verygood way to do that

Do u have a better idea for me?

Dear Douglenator,
What exactly do you need to achieve? Delete multiple files at once?

Normally, the users should be able to delete files one by one like this:
