Saincheaptha JavaScript sa riarachánLink to this heading#

Imeachtaí foirm inlíneLink to this heading#

B'fhéidir gur mhaith leat roinnt JavaScript a fhorghníomhú nuair a chuirtear foirm inlíne leis nó baintear san fhoirm athraithe riaracháin. Ceadaíonn na himeachtaí formset:added agus formset:removed seo. Is é Event.detail.FormSetName an tacar foirme leis an tsraith a bhaineann leis. Maidir leis an imeacht formset:added, is é event.target an tsraith nua-bhreise.

I do theimpléad saincheaptha change_form.html, leathnaigh an bloc admin_change_form_document_ready agus cuir an cód éisteora imeachta leis:

{% extends 'admin/change_form.html' %}
{% load static %}

{% block admin_change_form_document_ready %}
{{ block.super }}
<script src="{% static 'app/formset_handlers.js' %}"></script>
{% endblock %}

document.addEventListener('formset:added', (event) => {
    if (event.detail.formsetName == 'author_set') {
        // Do something
    }
});
document.addEventListener('formset:removed', (event) => {
    // Row removed
});

Dhá phointe le coinneáil i gcuimhne:

• Caithfidh an cód JavaScript dul i mbloc teimpléad má tá tú ag oidhreacht admin/change_form.html nó ní dhéanfar é a léiriú sa HTML deiridh.

• Cuirtear {{block.super}} `leis toisc go bhfuil cód JavaScript i mbloc ``admin_change_form_document_ready Django chun oibríochtaí éagsúla a láimhseáil sa fhoirm athraithe agus ní mór dúinn é sin a léiriú freisin.

function handleFormsetAdded(row, formsetName) {
    // Do something
}

$(document).on('formset:added', (event, $row, formsetName) => {
    if (event.detail && event.detail.formsetName) {
        // Django >= 4.1
        handleFormsetAdded(event.target, event.detail.formsetName)
    } else {
        // Django < 4.1, use $row and formsetName
        handleFormsetAdded($row.get(0), formsetName)
    }
})
