Remove dynamically generated textboxes

Question

I have the following javascript that dynamically add textboxes together with a remove button to a div. How can I using the remove button delete the content of the row being selected to delete?

<script type="text/javascript">
function GetDynamicTextBox(value) {
    return('' +
        '<div class="col-md-2">' +
        '  <input type="text" name="events[0].Key" value=""/>' +
        '</div>' +
        '<div class="col-md-2">' +
        '  <input type="text" name="events[0].Value.StartDate" value=""/>' +
        '</div>' +
        '<div class="col-md-2">' +
        '  <input type="text" name="events[0].Value.EndDate" value=""/>' +
        '</div>' +
        '<div class="col-md-2">' +
        '  <input type="text" name="events[0].Value.Description" value=""/>' +
        '</div>' +
        '<div class="col-md-2">' +
        '  <button type="button" class="btn btn-sm btn-primary" onclick="RemoveTextBox(this)"><i class="fa fa-angle-right"></i> Remove</button>' +
        '</div>');
}
function AddTextBox() {
    var div = document.createElement('DIV');
    div.className = "form-group";
    div.innerHTML = GetDynamicTextBox("");
    document.getElementById("divcontent").appendChild(div);
}
function RemoveTextBox(div) {
    //document.getElementById("divcontent").removeChild(div.parentNode); // this does not work
iterateBoxesAndSetUniqueIds();
}

function iterateBoxesAndSetUniqueIds() {
    // Set unique names of each textbox
    var children = document.getElementById("divcontent").children; 
    for (i = 0; i < children.length; i++)
    {
        var el = children[i];
        el.name = 'events[' + i + '].Key'; // 
        el.id = 'events[' + i + '].Key';

        el.name = 'events[' + i + '].Value.StartDate'; 
        el.id = 'events[' + i + '].Value.StartDate';

        el.name = 'events[' + i + '].Value.EndDate'; 
        el.id = 'events[' + i + '].Value.EndDate';

        el.name = 'events[' + i + '].Value.Description'; 
        el.id = 'events[' + i + '].Value.Description';
    }
}


</script>

<button type="button" class="btn btn-sm btn-primary" onclick="AddTextBox()"><i class="fa fa-angle-right"></i> Add</button>

        <div id="divcontent">

        </div>

UPDATE I added a snippet for updating the id for each textbox, but obviously I am doing something wrong here. Can anyone help with this too?

Answer 1

I assume you want to remove the entire row, so heres how to do that.

You almost had it, since you pass (this) in the onclick , it means we have a direct reference to the button that was clicked. From there, we can get its grandparent by using .parentNode twice (since the first parent is .col-md-2 ) and then use the remove() function.

div.parentNode.parentNode.remove()

 function GetDynamicTextBox(value) { return('' + '<div class="col-md-2">' + ' <input type="text" name="events[0].Key" value=""/>' + '</div>' + '<div class="col-md-2">' + ' <input type="text" name="events[0].Value.StartDate" value=""/>' + '</div>' + '<div class="col-md-2">' + ' <input type="text" name="events[0].Value.EndDate" value=""/>' + '</div>' + '<div class="col-md-2">' + ' <input type="text" name="events[0].Value.Description" value=""/>' + '</div>' + '<div class="col-md-2">' + ' <button type="button" class="btn btn-sm btn-primary" onclick="RemoveTextBox(this)"><i class="fa fa-angle-right"></i> Remove</button>' + '</div>'); } function AddTextBox() { var div = document.createElement('DIV'); div.className = "form-group"; div.innerHTML = GetDynamicTextBox(""); document.getElementById("divcontent").appendChild(div); } function RemoveTextBox(div) { div.parentNode.parentNode.remove() }

 <button type="button" class="btn btn-sm btn-primary" onclick="AddTextBox()"><i class="fa fa-angle-right"></i> Add</button> <div id="divcontent"> </div>

 function GetDynamicTextBox(value, uniquedId) { return('' + '<div class="col-md-2">' + ' <input type="text" name="events[0].Key" value=""/>' + '</div>' + '<div class="col-md-2">' + ' <input type="text" name="events[0].Value.StartDate" value=""/>' + '</div>' + '<div class="col-md-2">' + ' <input type="text" name="events[0].Value.EndDate" value=""/>' + '</div>' + '<div class="col-md-2">' + ' <input type="text" name="events[0].Value.Description" value=""/>' + '</div>' + '<div class="col-md-2">' + ' <button type="button" class="btn btn-sm btn-primary" onclick="RemoveTextBox(\'' + uniquedId +'\')"><i class="fa fa-angle-right"></i> Remove</button>' + '</div>'); } function AddTextBox() { var uniquedId = Math.floor(Math.random() * 100) + '_unique'; var div = document.createElement('DIV'); div.setAttribute("id", uniquedId); div.className = "form-group"; div.innerHTML = GetDynamicTextBox("", uniquedId); document.getElementById("divcontent").appendChild(div); } function RemoveTextBox(uniquedId) { var elem = document.getElementById(uniquedId); return elem.parentNode.removeChild(elem); }

 <button type="button" class="btn btn-sm btn-primary" onclick="AddTextBox()"><i class="fa fa-angle-right"></i> Add</button> <div id="divcontent"> </div>

function AddTextBox() {
    var uniquedId = Math.floor(Math.random() * 100) + '_unique';
    var div = document.createElement('DIV');
