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:
<code class="html"><template> <div>组件内容</div> </template> <script> export default { data() { return { message: 'Hello world!' }; } }; </script></code>
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:
<code class="html"><template> <div>组件内容</div> </template> <script src="component.js"></script></code>
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.
