Where should the script tag in vue be placed?

The script tag in Vue should be immediately following the template element <template> to achieve tight coupling of logic and templates and ensure the normal operation of the component.

The script tag position in Vue

The script tag in Vue is an important element for writing component logic . Its placement affects how the component behaves.

Correct Placement

The script tag should always be placed inside the template element <template>, and immediately after it. For example:

<template>
  <div>组件内容</div>
</template>

<script>
export default {
  data() {
    return {
      message: 'Hello world!'
    };
  }
};
</script>

Reason for placement

Placing the script tag inside the template can ensure that the logic of the component and the template are tightly coupled, thereby improving the clarity and readability of the code. Maintainability. This way, when the template changes, Vue can automatically detect it and update the component's logic accordingly.

Wrong Placement

Avoid placing script tags outside the template as this will cause the component to not work properly. The following is an incorrect example:

<template>
  <div>组件内容</div>
</template>

<script src="component.js"></script>

In the above example, the external script file has no dependency on the template element, causing Vue to be unable to associate the component logic with the template.
