Uncaught ReferenceError: vm is not defined vue.js 2.0
回答1
As mentioned by @Fiete the vm
variable wont be available by default.
You need to define vm
globally to access it from the console.
Something like this should work
var vm = new Vue({
el: '#app',
data: {
a: 1
},
router,
template: '<App/>',
components: {
App
}
});
global.vm = vm; //Define you app variable globally
Now you can use vm.$data.PROPERTY
or vm.PROPERTY
.

The vm
variable does not exists by default. And vuejs does not set that variable. If you want to debug your vuejs application I recommend the vuejs Chrome extension.
By opening the extension on your page you can select the component you want to debug. After that you can access the selected component by using the $vm0
variable.
