I'm using Vuesax Framework Components which it's working fine, but my in learning process for both laravel/vue.js and got a problem about how to use properties of component when input text got changed?
Consider this :
<vs-input
style="width:100%"
label="Label"
danger-text="character"
v-model="form.invoice_title"
name="invoice_title"/>
in top code component gonna show me a input text with a red color with text which will tell use what is wrong, but in right idea i should make that red color show when something is wrong with inputs, like `input must be more than 3 Characters'.
Input Component in vuesax
So here's what i wanna do make my input activate/trigger :danger & danger-text properties when something is wrong Like:
inputs must be more than 6 and less than 80 characters.

This can be done via a computed property. eg:
<vs-input
style="width:100%"
label="Label"
:danger="hasError"
:danger-text="errorText"
v-model="form.invoice_title"
name="invoice_title"/>
... // in javascript
computed()
hasError()
return this.form.invoice_title.length < 6
errorText()
if (this.form.invoice_title.length < 6)
return 'Invoice title should be at least 6 characters'
if (this.form.invoice_title.length > 80)
return 'Invoice title should be at most 80 characters'
return ''

note that I used a colon (:) that designates it's a bound property, alias tov-bind:danger-text. If you don't it will just use the variable you give it as text.
