[Vuejs]-I am not able to pass values of lat and lng in vue js?

v-model isn’t recognizing that the value attribute of your “lat” input field has been programmatically changed. Instead, you can do something like this:

<input name="lat" type="text" id="lat" ref="myLatField" v-model="lat">

methods: {
    handelSubmit: function(e) {
       var vm = this;
       data = {};
       data['lat'] = this.$refs.myLatField.value;
       ...
