Vue.js: Set checkboxes checked if statement is true

Related searches

I had the following checkbox in my old handlebar view:

<div class="form-group">
    <input type='checkbox' name='xmlOnline[]' value="stepstone" class='' {{#if (ifIn 'stepstone' job.xmlOnline)}} checked="checked" {{/if}}> Stepstone
    <input type='checkbox' name='xmlOnline[]' value="karriere" class='' {{#if (ifIn 'karriere' job.xmlOnline)}} checked="checked" {{/if}}> Karriere

So if job.xmlOnline has "stepstone" as value, it should mark it as checked. Same goes for "karriere".

Now I am trying to achieve the same thing in Vue.js for my POST form. This is how the object "job" looks like:

So it can contain either "karriere", "stepstone", both or "null".

What I got so far in my component:

<div v-for="(xml, index) in job.xmlOnline">
    <input type="checkbox" :checked="xml == 'stepstone'"> Stepstone {{ index }}
    <input type="checkbox" :checked="xml == 'karriere'"> Karriere {{ index }}

Checkboxes get checked, but I have them duplicated. I also do not know how to add a v-model.

This is the source of my component. Did something similiar with "qualifications"/"responsibility":

A possible solution

<input type="checkbox" 
       :checked="job.xmlOnline && job.xmlOnline.includes('stepstone')"
       @change="onChange('stepstone', $event)"> Stepstone
<input type="checkbox" 
       :checked="job.xmlOnline && job.xmlOnline.includes('karriere')"
       @change="onChange('karriere', $event)"> Karriere

And the onChange method

  onChange(value, $event){
    if (!this.job.xmlOnline)
      this.job.xmlOnline = []

    const index = this.job.xmlOnline.findIndex(v => v == value) 
    const checked = $

    if (checked && index < 0)
    if (!checked && index >= 0)
      this.job.xmlOnline.splice(index, 1)

A similar method to Andree's that I personally use would be to put the value in row one above each corresponding checkbox column. I then use the same formula but replace the first bit with references locked to row one. In the below example, the column names are bold and underlined. Each column is set to a checkbox.

Vue.js version. 1.0.26. What is Expected? The checkboxes binded with Vuejs can have THREE states: true, false, or indeterminate. For example, when binded with a checkbox and the value is "indeterminate", the checkbox's indeterminate property is set to true.

Only the value(s) of the checked checkboxes will be returned in the v-model bound array. You should provide a unique value for each checkbox's value prop (the default of true will not work when bound to an array) To pre-check any radios, set the v-model to the value(s) of the checks that you would like pre-selected.

  • Thanks! Working perfectly :) Can you help me how I would post this checkbox when I add a new job?
  • I also forgot, that it is also possible, that job.xmlOnline can also contain nothing. :/
  • @mrks When you say nothing do you mean it's null, or that it's an empty array. If it's an empty array, it will still work as in the answer. As far as how would you post it, that depends on your server side.
  • Sorry to be not clear enough. I meant that it can be also "null" like in this example: 57c52e875028100300236b6b
  • Perfect! Thank you very much! :-) Any last recommendations on my first comment (how to use v-model) when posting a new "job"?
