How to dynamically add rows to a form in html when i click on add row button?

Question

<div class="row">
    <div class="col-md-4">
        <div class="form-group label-floating">
            <label class="control-label">Act</label>
            <input type="text" class="form-control" v-model="act" >
        </div>
    </div>
    <div class="col-md-4">
        <div class="form-group label-floating">
            <label class="control-label">Section </label>
            <input type="text" class="form-control" v-model="section">
        </div>
    </div>
    <button>Add row</button>
</div>

So, when I click on add button, i need to keep on adding the above row. How can I able to add this row when I click on add row button.

I need to pass values as BOOKED UNDER :

[{
    act :,
    section:,
}]

If I have more rows i need to pass values as comma seperated. I am weak in js and this is my first project having this kind of problem. How can I able to add values in this way.

My vue js code is

addForm = new Vue({
    el: "#addForm",
    data: {
        bookedUnder:[],
        act: '',
        section:'',
    },
    methods: {
        handleSubmit: function(e) {
            var vm = this;
            data['otherNatureofOffense'] = //in the abve way
            $.ajax({
                url: 'http://localhost:3000/record/add/f/',
                data: data,
                type: "POST",
                dataType: 'json',
                success: function(e) {
                    if (e.status) {
                        vm.response = e;
                        alert("success")
                    } else {
                        vm.response = e;
                        console.log(vm.response);
                        alert(" Failed") 
                    }
                }
            });
            return false;
        }, 
    },
});

Please help me to have a solution

Solution 1

You need to v-for the fields first then post the model like this:

<div class="row" v-for="(book, index) in bookedUnder" :key="index">
    <div class="col-md-4">
        <div class="form-group label-floating">
            <label class="control-label">Act {{index}}</label>
            <input type="text" class="form-control" v-model="book.act" >
        </div>
    </div>
    <div class="col-md-4">
        <div class="form-group label-floating">
            <label class="control-label">Section {{index}}</label>
            <input type="text" class="form-control" v-model="book.section">
        </div>
    </div>

</div>
<button @click="addNewRow">Add row</button>



addForm = new Vue({
    el: "#addForm",
    data: {
        bookedUnder:[
          {
             act: null,
             section: null,
          },
        ],
    },
    methods: {
        addNewRow: function() {
          this.bookedUnder.push({ act: null, section: null, });
        },
        handleSubmit: function(e) {
            var vm = this;
            $.ajax({
                url: 'http://localhost:3000/record/add/f/',
                data: vm.bookedUnder,
                type: "POST",
                dataType: 'json',
                success: function(e) {
                    if (e.status) {
                        vm.response = e;
                        alert("success")
                    } else {
                        vm.response = e;
                        console.log(vm.response);
                        alert(" Failed") 
                    }
                }
            });
            return false;
        }, 
    },
});

If you use javascript or jquery this may helpful

var count=1;
$("#btn").click(function(){
  
  $("#container").append(addNewRow(count));
  count++;

});

function addNewRow(count){
  var newrow='<div class="row">'+
    '<div class="col-md-4">'+
        '<div class="form-group label-floating">'+
            '<label class="control-label">Act '+count+'</label>'+
            '<input type="text" class="form-control" v-model="act" >'+
        '</div>'+
    '</div>'+
    '<div class="col-md-4">'+
        '<div class="form-group label-floating">'+
            '<label class="control-label">Section '+count+'</label>'+
            '<input type="text" class="form-control" v-model="section">'+
        '</div>'+
    '</div>'+    
'</div>';
  return newrow;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>

            <label class="control-label">Act</label>
            <input type="text" class="form-control" v-model="act" >
        </div>
    </div>
    <div class="col-md-4">
        <div class="form-group label-floating">

            <input type="text" class="form-control" v-model="section">

</div>
<button id="btn">Add row</button>

Solution 3

Try please,

document.getElementById("clickMe").onclick = function () { 
        //first div
        var newDivCol = document.createElement("div");
        newDivCol.setAttribute("class","col-md-4");
        //second div
        var newDivForm = document.createElement("div");
        newDivForm.setAttribute("class","form-group label-floating");
        newDivCol.appendChild(newDivForm);

        //label
        var newlabel = document.createElement("label");
        newlabel.setAttribute("class","control-label");
        newlabel.innerHTML = "Here goes the text";
        newDivForm.appendChild(newlabel);

        //input
        var newInput = document.createElement("input");
        newInput.setAttribute("type","text");
        newInput.setAttribute("class","form-control");
        newInput.setAttribute("v-model","act");
        newDivForm.appendChild(newInput);

        var element = document.getElementById("addRowsHere");
        element.appendChild(newDivCol);
};

<div class="row" id="addRowsHere">
    <div class="col-md-4">
        <div class="form-group label-floating">
            <label class="control-label">Act</label>
            <input type="text" class="form-control" v-model="act" >
        </div>
    </div>
    <div class="col-md-4">
        <div class="form-group label-floating">
            <label class="control-label">Section </label>
            <input type="text" class="form-control" v-model="section">
        </div>
    </div>
</div>
<button id="clickMe">Add row</button>

[Bakhtier Gaibulloev]

Should do what do you want. At the bottom the link, where you can check it.

[Wanderer]

how to obtain the result as in the above question? Can you please help me

[Wanderer]

how to pass the values in this format [{ act :, section:, }]

[Wanderer]

Also i need to display the first row before i click the button

[Indyz]

To display the row before you could either insert the HTML above the v-for or automatically call addRow() on start (in this case after the HTML has been mounted alligator.io/vuejs/component-lifecycle) To still have the act and section values you could just extend your code with something similar to the example. This is only an example of a concept, you'll have to implement it on your own.

Thank you sir.. you saved me
