I have some data that is accessible via:
{{ content['term_goes_here'] }}
... and this evaluated to either true or false. I'd like to add a class depending on the truthiness of the expression like so:
<i class="fa" v-bind:class="[{{content['cravings']}} ? 'fa-checkbox-marked' : 'fa-checkbox-blank-outline']"></i>
where true gives me the class fa-checkbox-marked and false would give me fa-checkbox-blank-outline. The way I wrote it above gives me an error:
- invalid expression: v-bind:class="[{{content['cravings']}} ? 'fa-checkbox-marked' : 'fa-checkbox-blank-outline']"
How should I write it to be able to conditionally determine the class?
This question is related to
javascript
vue.js
vuejs2
conditional-formatting
<i class="fa" v-bind:class="cravings"></i>
and add in computed :
computed: {
cravings: function() {
return this.content['cravings'] ? 'fa-checkbox-marked' : 'fa-checkbox-blank-outline';
}
}
if you want to apply separate css classes for same element with conditions in Vue.js you can use the below given method.it worked in my scenario.
html
<div class="Main" v-bind:class="{ Sub: page}" >
in here, Main and Sub are two different class names for same div element. v-bind:class directive is used to bind the sub class in here. page is the property we use to update the classes when it's value changed.
js
data:{
page : true;
}
here we can apply a condition if we needed. so, if the page property becomes true element will go with Main and Sub claases css styles. but if false only Main class css styles will be applied.
Why not pass an object to v-bind:class to dynamically toggle the class:
<div v-bind:class="{ disabled: order.cancelled_at }"></div>
This is what is recommended by the Vue docs.
the problem is blade, try this
<i class="fa" v-bind:class="['{{content['cravings']}}' ? 'fa-checkbox-marked' : 'fa-checkbox-blank-outline']"></i>
