Reset to default 1Give all of the check boxes that could potentially be deleted the same class. Additionally label all of the text boxes that could be deleted with their own class. My check boxes will be labeled with chk and my text boxes will be labeled with txt. As in:
<input type="checkbox" class = 'chk' /> and
<input type="text" class = 'txt' />
The following solution should work as long as check boxes and text fields are 1 to 1.
the function you will add to your delete button will loop through all of the check boxes and see if they are deleted and then delete the checked ones.
Heres the JS:
function delBoxes(){
var boxes = document.getElementsByClassName('chk');
var texts = document.getElementsByClassName('txt');
for(var i = 0; i<boxes.length; i++){
box = boxes[i];
txt = texts[i];
if(box.checked){
box.parentNode.removeChild(box);
txt.parentNode.removeChild(txt);
}
}
}
That will delete all of the checked check boxes, all you have to do now is make a button and add that function as an onclick.
<input type="button" value="Delete checked boxes" onclick = "delBoxes();" />
Sample HTML
<div>
<input type='checkbox' value='asd' id='test' name='test' />
<input type='checkbox' value='asd' id='tester' name='test' />
<input type='button' value='remove' id='rmvBtn' />
</div>
In pure javascript, you can do this,
var rmvBtn = document.getElementById('rmvBtn');
rmvBtn.addEventListener('click', function(){
var rmvCheckBoxes = document.getElementsByName('test');
for(var i = 0; i < rmvCheckBoxes.length; i++)
{
if(rmvCheckBoxes[i].checked)
{
removeElm(rmvCheckBoxes[i]);
}
}
});
function removeElm(elm){
elm.parentElement.removeChild(elm);
}
JS Fiddle
HTML
<input type="checkbox" id="checkboxid" name="checkboxname">
<button id="btnDeleteid" onclick="deleteCheckBox()" name="btnDeletename">Delete</button>
JavaScript
function deleteCheckBox(){
if (document.getElementById('checkboxid').checked){
var answer = confirm('Are you sure you want to delete this checkbox?');
if (answer)
{
$("#checkboxid").remove();
}
}else{
alert("Pls check the checkbox.");
}
}
I hope this will help.
