tengo un formulario:
<form id="carForm"> <div class="form-field"> <label for="">Year:</label><br> <input id="year" type="number" placeholder="1990" required> </div> <div class="form-field"> <label for="">Mileage(km):</label><br> <input id="mileage" type="number" placeholder="30000" required> </div> <div class="form-field"> <label for="">Brand:</label><br> <input id="brand" type="text" placeholder="Mercedes" maxlength="20" required> </div> <div class="form-field"> <label for="">Maintenance:</label><br> <input id="maintenance" type="number" placeholder="0000" > </div> <div class="form-field"> <label for="">Cooling system:</label><br> <input id="cooling" type="number" placeholder="0000" > </div> <div class="form-field"> <label for="">Total amount:</label><br> <input id="total" type="number" placeholder="0000" disabled> </div> <div class="submit-btn"> <input type="submit" value="Add"> </div> </form>Y un método de envío:
let dataToSend = { repair: { year: yearField.value, total_amount: totalField.value, mileage: mileageField.value, brand: brandField.value, items: { maintenance: maintenanceField.value, cooling_system: coolingField.value, } axios({ method: "post", url: 'url', data: { dataToSend },¿Cómo enviar solo campos que contienen el valor? Por ejemplo: el valor de entrada del sistema de refrigeración es 1.000 y el valor de entrada de mantenimiento es 0. ¿Cómo enviar solo ese campo (sistema de refrigeración)?
En ES6, puedes hacer
...(condition && {key: value})Tomando tu ejemplo:
const coolingField = {value: 1}; const maintenanceField = {value: 0}; let dataToSend = { repair: { items: { ...(coolingField.value > 0 && { maintenance: coolingField.value }), ...(maintenanceField.value > 0 && { cooling_system: maintenanceField.value }) } } };Aquí hay una manera de hacerlo.
let dataToSend = { repair: { year: 15, total_amount: '', mileage: 232, brand: 'asa', items: { maintenance: '', cooling_system: 12, } } } // Remove empty key values const clearEmpties = (obj) => { for (var propName in obj) { if (typeof obj[propName] == "object") clearEmpties(obj[propName]) if (obj[propName] === null || obj[propName] === undefined || obj[propName] ==='') delete obj[propName]; } return obj } console.log(clearEmpties(dataToSend)) /* axios({ method: "post", url: 'url', data: { clearEmpties(dataToSend) }) */puedes usar condiciones como
if(maintenanceField.value > 0 && coolingFieldValue <= 0 ){ items: { maintenance: maintenanceField.value } } elseif(maintenanceField.value <= 0 && coolingFieldValue > 0){ items: { cooling_system: coolingField.value } else{ items: { maintenance: maintenanceField.value, cooling_system: coolingField.value, } }}
