How to embed web pages in vue

When developing a web application, many times we need to embed external web pages (such as maps, payment pages, etc.) into our own web pages. How to achieve this? There are many ways to implement embedded web pages in Vue. Let’s introduce them one by one below.

1. iframe method

The simplest method is to use the iframe tag in HTML to embed the external web page into the main page as an embedded window. In Vue, this can be achieved as follows:

<template>
  <div class="container">
    <iframe
      src="http://example.com"
      frameborder="0"
      width="100%"
      height="100%"
    ></iframe>
  </div>
</template>

Here we set the src-iframe embedded external web page address, frameborder-set the border, width and height set the width and height of the iframe respectively.

However, this method has certain limitations. Generally speaking, iframes will slow down page loading and affect user experience, and browser security policies may also limit the use of iframes. Therefore, we need to consider other methods.

2. object method

You can also use the object tag to embed web pages in Vue.

<template>
  <div class="container">
    <object :data="url" type="text/html" width="100%" height="100%"></object>
  </div>
</template>
<script>
export default {
  data() {
    return {
      url: "http://example.com",
    };
  },
};
</script>

In this example, we specify the URL to embed through the data attribute. Using the object tag optimizes performance and improves security compared to iframes. In addition, object is actually an embedded method recommended by W3C.

However, there are also some limitations. For example, the object tag may not work on some browsers or pages.

3. Vue-iframe method

Vue-iframe is a plug-in specially developed for Vue, which solves the problems of the above two methods to a certain extent. It makes working with iframes easier and provides some additional features such as customizable content CSS, automatic adjustment of iframe height, and more. The specific usage is as follows:

First, we need to install Vue-iframe:

npm install vue-iframe

Then, we need to introduce Vue-iframe into Vue:

import VueIframe from "vue-iframe";

Vue.use(VueIframe);

Finally, we You can use Vue-iframe to embed web pages:

<template>
  <div class="container">
    <vue-iframe url="http://example.com" :styles="{ height: '100%' }" />
  </div>
</template>

Vue-iframe can accept multiple attributes and can help us easily control the iframe. The url attribute is required and specifies the URL to be embedded. The styles attribute is optional and is used to customize the style of the iframe (as in the above example, the height style is used to set the iframe height).

Summary

The above are three methods of embedding web pages in Vue. Which method to use depends on your project needs and preferences. If you simply need to embed a web page, either iframe or object will do the job. If you need more advanced features, such as automatically adjusting iframe height, etc., you can choose Vue-iframe. Whichever method you choose, remember to consider performance and security.
