vuejs disable button depending array length












0














I am trying to disable/enable a button depending of an array length and so, my code is the following:



  <button class="submit-button"
type="button"
v-on:click="DoSomething()"
:disabled="array.length > 0">Submit</button>


Although, this doesn't work and as response I have the warning:



array.length > 0 is not a valid value of attribute 'disabled'



Is there any different syntax to enable/disable a button regarding an array length?



Any help is welcome

    The problem is not in your code sample, using your code sample works fine. Here is a Fiddle https://jsfiddle.net/koLjsux6/ with your Code Sample. Please include other relevant code for us.

    The mistake isn't related to your button element. I copy/pasted your code into a fresh vue app and it's working without errors: codesandbox.io/s/qlm75pj61q Seems like the v-bind directive :disabled isn't receiving the value it's supposed to receive (true, false, null, undefined, defined...). You should print out the expression "array.length > 0" to see what it results in, the error must be located in there somewhere.
