I wish this help you In your methods define a function to get the duration for a given user and date:

getDuration(user_id, date) {
    const user = this.users.find(user => user.id == user_id);
    const hour = user.hours.find(hour => hour.date == date);
    return hour ? hour.duration : 0;
},

:value="getDuration(user.id, day)"

@input="e => setDuration(user.id, day, e.target.value)"

setDuration(user_id, date, duration) {
    const user = this.users.find(user => user.id == user_id);
    const hour = user.hours.find(hour => hour.date == date);
    if (hour) {
        hour.duration = duration;
    } else {
        user.hours.push({
            id: getNewId(), // <--- implement this!
            user_id,
            date,
            duration
        });
    }
},

            id: getNewId(), // <--- implement this!

Bind value from input to properties of an object

may help you . Assuming that shareholderis an object on your 'myController', do this:

<div ng-controller="myController as $ctrl">

    <input name="shares" ng-model="$ctrl.shareholder.shares"  type="number" required />
    <input name="name" ng-model="$ctrl.shareholder.name" required />

</div>

$scope.shareholder = { 
    shares: 'value from input'
    name: 'value from input'
}

<input name="shares" ng-model="shareholder.shares"  type="number" required />
<input name="name" ng-model="shareholder.name" required />

How can i bind input to object in vue.js

Does that help Is there a way to bind input to objects instead of single variables. , you can bind directly to data, code as follow:

var demo = new Vue({
    el: "#demo",
    data: {
      user: {
        name: "please enter"
      }
    }
})

<script src="https://unpkg.com/vue/dist/vue.min.js"></script>
<div id="demo">
  <input v-model="user.name">
  <span>{{user.name}}</span>
</div>

Bind specific index of an observableArray to an input control

Tag : knockout.js , By : ffmmjj

this will help Is there a reason you bind the parent div value and then pass $data when you can just provide the value binding directly to the input?

var ViewModel = function() {
    this.arr = ko.observableArray([
    {
      "SpecName": "reportingcurrency",
      "SpecValue": "EUR"
    },
    {
      "SpecName": "transactionscurrency",
      "SpecValue": "GBP"
    }
  ])
};	

ko.applyBindings(new ViewModel());

<script src="https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.2/knockout-min.js"></script>
<div>
    <input type="text" data-bind="value: arr()[0].SpecValue" />
</div>

Is there any way to bind drop down field options to specific input type in yii2

this will help Add some JavaScript that listens to the change of the dropdown and show/hide your elements based on the selected value.
I wrote a small example. You'll have to change the IDs to match your elements and maybe make some other small changes, but something like this should work.

<?php
$this->registerJs("
    $(function() {
        $('#your-form-media-type-id').on('change', function() {
            var value = this.value
            switch (value) {
                case 'text':
                    $('#your-mce-div').show();
                    $('#your-image-input-div').hide();
                break;

                case 'image':
                    $('#your-image-input-div').show();
                    $('#your-mce-div').hide();
                break;
            }
        });
   });
");

Bind HTML element to Javascript object and store object in array - Update object with input value from child element

Tag : javascript , By : gbodunski

it should still fix some issue One way to do this is to use a closure.
The purpose of a closure is to capture variables from the containing function so those variables can be used later, after the containing function exits.

let data = {
    nameGenerator: 0
};

function addInput() {
    // generate a new name and property in data object
    let propertyName = String.fromCharCode("a".charCodeAt() + data.nameGenerator++);
    // initialize property value to its name
    data[propertyName] = propertyName;

    // add <div><input value="(property)"></div> to container
    let containerElement = document.getElementById("container");
    let lineElement = document.createElement("div");
    let inputElement = document.createElement("input");
    lineElement.appendChild(inputElement);
    containerElement.appendChild(lineElement);

    // initialize input value (note: this does not bind the two, just initializes)
    inputElement.value = data[propertyName];

    // create a closure that binds the property to the element
    inputElement.addEventListener("keyup", function () {
        // inside this function, propertyName and inputElement 
        // are "captured" in the closure
        data[propertyName] = inputElement.value;
    })
}
