Problem Description:

Interpolation syntax and ternary expression are used in Vue page. The above error is reported, but it can run normally;

Error code, such as:

<p>{{num<0?"Hello":"hello"}}</>

Error message

[vue/no-parsing-error]
Parsing error: invalid-first-character-of-tag-name.eslint-plugin-vue
Parsing error: invalid-first-character-of-tag-name.eslint(vue/no-parsing-error)

Problem resolution:

The above code can run normally, but eslint will report an error because a separate & lt; will be verified in the HTML code; It will be considered by eslint as a part of HTML code rather than a template language, but Vue will parse this part of the expression and then output it, so it can run normally

Solve the error reported by eslint:

Method 1: we can use the escape character < to < or > Number replacement

<p>{{ (num < 1) ?"Hello":"hello" }}</p>

Method 2: use the v-text instruction

<p v-text="(num < 1) ?'Hello':'hello'"></p>
