What is the best way to display a data property on screen?

Question

What is the best way to display a data property on screen?

I'm starting with a very basic layout:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <title></title>

    <link rel="stylesheet" type="text/css" href="Content/dictionary.css" />

    <script src="Scripts/kuroshiro.min.js"></script>
</head>
<body>
    <div id="searchResultsVue">
        <table>
            <tr v-for="r in results">
                {{ r.Result.ent_seq }}
            </tr>
        </table>
    </div>


    <script src="https://vuejs.org/js/vue.js"></script>
    <script>


        var searchResultsVue = new Vue({
            el: '#searchResultsVue',
            data: { results: [{ Result: { ent_seq: 'asd' } }] }
        });
    </script>
</body>
</html>

However, an issue arises:

[Vue warn]: Property or method "r" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. See: https://v2.vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.

I'm puzzled by this error message

Answer №1

One common issue arises from HTML's lenient rendering practices. When constructing DOM elements for a table, a specific structure is expected. Any deviation from this structure can cause elements to be pushed outside the defined boundaries.

For example:

<table>
    <tr v-for="r in results">
        {{ r.Result.ent_seq }}
    </tr>
</table>

May transform into:

<table>
    <tr v-for="r in results">
    </tr>
</table>
{{ r.Result.ent_seq }}

The error occurs when the loop variable is referenced outside of the loop.

By enclosing your code within a table definition tag like this fiddle shows, you can prevent elements from being displaced.

It is important to correct your code structure. Ensure that the tr element has a child td for it to function correctly.

<tr v-for="r in results">
  <td>{{ r.Result.ent_seq }}</td>
</tr>

Answer №3

You must place the td tag within a tr element. It appears that there is something unique about table rows

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <title></title>
</head>
<body>
    <div id="searchResultsVue">
        <table>
            <tr v-for="r in results">
                <td>{{ r.Result.ent_seq }}</td>
            </tr>
        </table>
    </div>;


    <script src="https://vuejs.org/js/vue.js"></script>
    <script>
        var searchResultsVue = new Vue({
            el: '#searchResultsVue',
            data: { results: [{ Result: { ent_seq: 'asd' } }] }
        });
    </script>
</body>
</html>
