What could be causing the invalid expression error to pop up in my Vue.js template?

I encountered an error within my vue single file component:

  Errors compiling template:

  invalid expression: Unexpected token { in

    {{ jobs[0].build_link }}

  Raw expression: v-bind:href="{{ jobs[0].build_link }}"

The complete code causing the issue is:

 <td :style=tdStyle><a v-bind:href="{{ jobs[0].build_link }}">{{ jobs[0].build_link }}</a></td>

The 'jobs' variable is defined within the data method of my component and can be console.logged without any problems.

Interestingly, this line works perfectly with an inline-template in Vue.js script but throws an error once converted to a single page component.

Answer №1

It appears there may be a syntax issue present. Have you tried removing the curly braces? For example:

<td :style=tdStyle><a v-bind:href="jobs[0].build_link">{{ jobs[0].build_link }}</a></td>

Give that a shot and hopefully it resolves the problem..

Answer №2

In this scenario, it is appropriate to remove the curly braces because the v-bind syntax will already evaluate the expression. Using double curly braces would pre-evaluate it as a string, resulting in trying to evaluate a string instead. Therefore, you would end up with something like 

v-bind:href="https://google.com"
, where "https://google.com" is not a variable or expression. Does that make sense?
