i have a javascript code for change automatic placeholder from change keyword. This is the smallest part of the code :
$("#addrow").on("click", function () {
counter = $('#myTable tr').length -1;
var newRow = $("<tr>");
var cols = "";
....
cols += '<td><input type="text" name="keyword' + counter + '" placeholder="add keyword in here.." style="width: 425px;"/></td>';
cols += '<td><input type="button" class="ibtnDel" value="-"></td>';
newRow.append(cols);
//if (counter == 4) $('#addrow').attr('disabled', true).prop('value', "You've reached the limit");
$("table.order-list").append(newRow);
counter++;
$("#list_field"+counter).change(function(){
if ($(this).val() == 'all'){
$("input[name=keyword]").attr('placeholder', 'add keyword in here');
}
else if ($(this).val() == 'chrom'){
$("input[name=keyword]").attr('placeholder', 'ex: 8');
} });
});
that was the problem for me is how to add the variable "counter" in "$("input[name=keyword]").attr('placeholder', 'add keyword in here');"
. is like this? ->
$("input[name=keyword]").counter.attr('placeholder', 'add keyword in here');
sorry I am still learning about javascript. thanks for your solution.
if you want add a variable in text of placeholder here is the code
var counter =1 ;
$("input[name=keyword]").attr('placeholder', 'add keyword in here '+counter);
if you want discriminate each input you can add an id
var counter =1 ;
$("input[name=keyword]").attr('id', counter);
also you can find an element with css selector nth-child(number-of-item)
html
<input class="input" palceholder="blabla1">
<input class="input" palceholder="blabla2">
<input class="input" palceholder="blabla3">
javascript
var counter =1 ;
$(".inputs:nth-child("+counter+")")
