angular.js - Is it possible to two-way data bind iframe elements through vue or angular?

Question

I would like to ask you about developing a management system for H5 games. I want to synchronize the content of the page elements in the iframe in real time when inputting content in the background. I would like to know what technology can be used to achieve this? Can vue and angular achieve this?

The effect is as follows:

Answer 1

parent.html

<p id="app">
    <input type="text" v-model="item.name" />
    <input type="checkbox" v-model="item.check" />
    <input type="date" v-model="item.date" />
    <iframe ref="iframe" src="child.html" @load="load"></iframe>
</p>

<script src="http://cdn.bootcss.com/vue/2.1.8/vue.min.js"></script>

<script>
    window.app = new Vue({
        el: '#app',
        data() {
            return {
                item: {
                    name: null,
                    check: false,
                    date: null,
                },
            }
        },
        methods: {
            load: function (item) {
                const app = this.$refs.iframe.contentWindow.app;

                if (app && app.setContent) {
                    app.setContent(this.item)
                }
                else {
                    window._item = this.item
                }
            }
        }
    })
</script>

child.html

<p id="app">
    {{ item }}
</p>

<script src="http://cdn.bootcss.com/vue/2.1.8/vue.min.js"></script>

<script>
    window.app = new Vue({
        el: '#app',
        data() {
            return {
                item: null,
            }
        },
        created: function () {
            this.setContent(window.parent.window._item);
        },
        methods: {
            setContent: function (item) {
                this.item = item;
            }
        }
    })
</script>

Or pass the vuex store to use the same store for the vue instances of the two pages

Answer 2

If you use iframe, you can only use websocket to notify of updates. The two-way data of vue and ag can only be updated in real time on the same page

Answer 3

iframe is cross-page. It is extremely unsafe and impossible for others to use ng or vue to operate your page.

You can try postMessage.
