How to send parameters through the Google Maps API URL using Vue.js

When using $router.push(), I receive two parameters: {{ this.$route.params.lat }} and {{ this.$route.params.lng }}, which are latitude and longitude coordinates.

To access a Google Maps URL, I need to include both of these parameters:

https://maps.googleapis.com/maps/api/staticmap?center={{ this.$route.params.lat }},{{ this.$route.params.lng }}&zoom=15&size=300x300&maptype=terrain&key=MY_API_KEY"

However, I encounter an error message when attempting to do so:

Interpolation inside attributes has been removed. Use v-bind or the colon shorthand instead. For example, instead of 

<div id="{{ val }}">
, use <div :id="val">.

What steps can I take to resolve this issue?

Answer №1

When encountering the error message, remember that you cannot utilize the {{ }} template syntax within HTML attribute values.

To resolve this issue, it is recommended to use the v-bind syntax

<img :src="`https://maps.googleapis.com/maps/api/staticmap?center=${this.$route.params.lat},${this.$route.params.lng}&zoom=15&size=300x300&maptype=terrain&key=MY_API_KEY`">

To handle URL encoding properly, consider creating a computed property to generate the URL

computed: {
  mapUrl () {
    const url = "https://maps.googleapis.com/maps/api/staticmap"
    const params = new URLSearchParams({
      center: `${this.$route.params.lat},${this.$route.params.lng}`,
      zoom: 15,
      size: "300x300",
      maptype: "terrain",
      key: "MY_API_KEY"
    })
    return `${url}?${params}`
  }
}

You can then utilize this computed property in your template

<img :src="mapUrl">
