JQuery Custom Save Button - Save, Validation, and Redirection Issues

Question

We have a custom list form that we are trying to save, validate, and redirect. We can get the button to save and validate, but not redirect. And vice versa. We have tried several variations on the lines in red, all with either
no save or no redirect. We are also using this custom list form on a custom master page.
Is there something that we are doing wrong?
<script>
$(document).ready(function() {
    var button = $("input[id$=SaveItem]");
    // change redirection behavior
        button.removeAttr("onclick");
        button.click(function() {
            var elementName = $(this).attr("name");
            var aspForm = $("form[name=aspnetForm]");
            var oldPostbackUrl = aspForm.get(0).action;
            var currentSourceValue = GetUrlKeyValue("Source", true, oldPostbackUrl);
            var newPostbackUrl = oldPostbackUrl.replace(currentSourceValue, "custompageurl.aspx")
            if (!PreSaveItem()) return false;
                                                if (SPClientForms.ClientFormManager.SubmitClientForm('WPQ1')) return false;
                                                if (!Page_ClientValidate()) return false;
                                                WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(elementName, "", true,
"", newPostbackUrl, false, true));
</script>

Hi,
From your description ,my understanding is that you want to redirect to your custom page after you create a new item.
You could accomplish you requirement via sessionvars.js file, please refer to this article:

Here is a similar case for reference:
