Within my template, there is this code snippet:
<input @input="myMethod(myVariableName)" />
Following that, I have the myMethod function:
myMethod(variablePassed) {
console.log(variablePassed)
}
Upon execution, I receive the value of the "variablePassed". However, I am curious if there is a way for me to identify which specific variable was passed.
You have the option to achieve this by enclosing the variable inside a literal object {} and utilizing Object.keys(varname)[0] to retrieve its name and Object.values(varname)[0] to retrieve its value:
Vue.config.devtools = false;
Vue.config.productionTip = false;
new Vue({
el: '#app',
data() {
return {
name: "john"
}
},
methods: {
myMethod(variablePassed) {
console.log(Object.keys(variablePassed)[0])
console.log(Object.values(variablePassed)[0])
}
}
})#app {
padding: 20px;
