I have a component for my bootstrap modal. The modal has a button is labeled "Got It",which I am trying to call a method found on the root instance. It is not working--I cannot tell what I am missing. I have added a click handler and emit the click, but cannot trigger the clear function? Please advise what is wrong- thanks
Vue.component('modal', {
template: '#modal-template',
props:{
bgClass:{
type:String,
default:'default'
},
},
methods: {
clickHandler () {
this.$emit('click');
}
}
})
new Vue({
el: "#app",
data: function data() {
return{
showModalZ:false
}
},
methods: {
clear: function(){
alert("checkme");
}
}
})

You need to emit 'close' event from model component clickHandler function and capture it on parent with #close
Working example:
Vue.component('modal', {
template: '#modal-template',
props: {
bgClass: {
type: String,
default: 'default'
}
},
methods: {
clickHandler() {
this.$emit('close');
}
}
})
new Vue({
el: "#app",
data: function data() {
return {
showModalZ: false
}
},
methods: {
clear: function() {
alert("checkme");
}
}
})

I am working on Vue.JS and I tried to use local-storage with it to save data. In my code, I can store and retrieve all data with local-storage except line-through effect. Here, I am trying to store actual boolean value of line-through effect in local-storage and want to retrieve that value on to-do list app.

var todolist = new Vue({

data : {
state : 'edit',
header: 'To Do List',
newItem: '',
newdate: '',
items: [
{
label:'coffee',
completed:false,
date:'2019-06-20' ,
},
{
label:'tea',
completed:false,

},
]
},
computed:{
itemsDone(){
return this.items.filter(items => items.completed)
},
itemsTodo(){
return this.items.filter(items =>! items.completed)
},
},
methods:{
saveItem: function(){
if (this.newItem != ''){
this.items.push({
label:this.newItem,
completed: false,
date : this.newdate,
});
this.newItem = '';
this.newdate = '';
}},
changeState: function(newState){
this.state = newState;
this.newItem = '';
this.newdate = '';
},
removeitems(index){
this.items.splice(index,1);
},
clearcompleted (){
this.items = this.itemsTodo;
},
clearAll: function(){
this.items = [ ];
},
},
mounted(){
console.log('App Mounted!');
if (localStorage.getItem('items')) this.items = JSON.parse(localStorage.getItem('items'));
},
watch: {
items:{
handler(){
localStorage.setItem('items',JSON.stringify(this.items));
},
},
},
});
</script>
I expect correct boolean value of line-through effect to be stored in local-storage. So that, appropriate effect will show on browser.
You are just watching items. If you change something in a item (in your case completed) the handler will not be called and your change is not stored.
You could use a "deep" watcher but i suggest to call your save logic whenever you changed something.
I'm learning vue.js , everything works fine on chrome. but on ie11, it doesn't parsing the {{}} tag.
And after i use npm to install babel-polyfill,and used it as a tag on my page, the problem remains.
here are some of my code.

mounted() {
axios
.get("/activity/gqzq/AjaxGetList?ls=" + this.ls + "&le=" + this.le)
.then(response => {
console.log(response.data);
this.jobsData = response.data.data;
this.total = response.data.total;
this.count = response.data.count;
})
.catch(error => {
console.log(error);
});
}
});
</script>

I developed a website for the WeChat Platform . The fronted website runs well on my own iphone. But these website won't work on others' phone, or the WeChat Windows version.

On my own iphone, when I click the test or register button , the js code runs well and the request send to the backend successfully, But on other phone , even the test button won't work. If I comment out the else block in the register function , all the devices runs well. When I replace axios with vue-resource, the same situation appeared. I don't know why.
