I have a form with user input and I serialize the data in JSON. What I want is that for each value of a specified key I want to add a prefix when the user should fill the input, like if the user introduce 123, the final output should be http://123, but just for one input field, not for every input field in my form.
This is my code, everything is working till I do the console log:
function convertFormToJSON(form) {
var array = jQuery(form).serializeArray();
var json = {};
jQuery.each(array, function() {
json[this.name] = this.value || '';
});
return json;
}
console.log(convertFormToJSON(document.getElementById("myform")));
var blah=convertFormToJSON(document.getElementById("myform")));
function addStringToValueInJSON(json, key, string) {
for (var i = 0; i < json.length; i++) {
json[i][key] = json[i][key] + string;
}
return json1;
}
function add() {
addStringToValueInJSON(blah, "test", "!");

const formData = new FormData(document.getElementById('myform'))

JSON[key] = `http://${value}`

for (let [key, value] of formData.entries()) {

const vals = value.split(',')
const finalValsArray = vals.map(val => `http://${val}`)
JSON[key] = finalValsArray.toString()
}
console.log(JSON)<form id="myform">
<input type="text" id="test" name="test" value="2,3,5">
</form>
