The HTML for the form is :

<input type="text"
id="minAmount" name="minAmount" class="form-control min"
style="border-radius: 1rem; width: 183px;"

js file
var countOfRows =1;
$(".addFlowLevelRow").click(function() {

var txt = $(this).closest("tr").find('#removeFlowLevelRow').attr('href');
if (txt == undefined && countOfRows < 5) {
var newRow = $(this).closest("tr").clone(true).appendTo("#add-flow-level").append(remv);
if(countOfRows == 4)
{
document.getElementsByClassName("addFlowLevelRow")[4].style.display = "none";
console.log("Removal of - button at row = "+countOfRows);
}
countOfRows++;
console.log("Number of row = "+countOfRows);
}
else if(countOfRows < 5){
var newRow = $(this).closest("tr").clone(true).appendTo("#add-flow-level");
if(countOfRows == 4)
{
document.getElementsByClassName("addFlowLevelRow")[4].style.display = "none";
console.log("Removal of - button at row = "+countOfRows);
}
countOfRows++;
console.log("Number of row =" +countOfRows);
}
var input = document.getElementsByClassName('max');
newRow.find('.min').val(input.value);
newRow.find('.max').val("");
newRow.find('#approver').val(0);
});
$(document).on('click', '#removeFlowLevelRow', function(e) {
console.log("view----");
$(this).closest("tr").remove();
countOfRows--;
console.log("After - Button count is = "+countOfRows);
});
$('#approver').on('change', function() {
alert("alerrt called");
var select = document.getElementById('approver');
var value = select.options[select.selectedIndex].value;
alert(value);
var index = value;
if (index > -1) {
// ${usersList}.splice(index, 1);
}
alert("ye ky tha"+select.value);
//return ${usersList};
});
I want that Super Admin to be disabled for the 2nd row and show values other than super Admin in that drop down. Whenever the user clicks on + button it creates a clone of the row. I have not created the new row separately but I want the new drop down to not have the value that are selected in the first drop down and this should go till 5 rows.
Solution
id's in the DOM should always be unique otherwise it can lead to strange behaviour in the page
so firstly you need to give each row's "approver" select
element a separate id e.g. approver0,1,2... (or just remove the id) and instead have a common class for these elements e.g. "form-control approver"
Then in your onchange function, loop through the approver
class and disable the select options that don't appear, here is some psuedo code to start working with
var a = document.getElementsByClassName("approver")
//loop through all approver select elements
for(i in a) {
if(a[i] = this) {
//do nothing if we loop to the element that has just been changed
}
else {
//if the approver select isn't the one we've just changed, loop through the options
options = a[i].childNodes
for(j in options){
if(options[j].value = this.value) {
//if the option matches the one we've just selected disable it
options[j].setAttribute("disabled")="disabled"
}
else {
//Otherwise re-enable it so we don't disable all elements by changing the selection
options[j].removeAttribute("disabled")
}
}
In this rudimentary example changing the next approver option will overwrite disabling the previous selection so you may need to also keep track of what has been selected in all other drop downs. but hopefully this gets you started
