I have defined a global variable Vue.prototype.url in main.js. The value of this variable is returned in the background. How can I monitor the change of this value in the vue component? Cannot listen using watch
watch: {
"url"(newVal,oldVal) {
console.log(newVal,oldVal)
}
}you can define it in the data of the root component, and vue will automatically listen
are you sure your way of writing is all right?
watch: {
'url': function(newVal,oldVal) {
console.log(newVal,oldVal)
}
}have you solved your problem? I have encountered the same situation
