- 1 Just an opinion, but I personally think you have an incredible amount of repetition. You should try and e up with a more intuitive way to do your jquery. You could make one function that has some parameters that help direct the Ajax what to do in different circumstances maybe figure a better way to handle same-named selectors, etc. It would probably help with manageability. – Rasclatt Commented Feb 9, 2016 at 5:57

Reset to default 2Make a function of your code inside change events and call wherever and when you want it to call, code for #streams change is below.
<script>
$(document).ready(function() {
$('#<?php echo $stream;?>').prop('selected', true);
$('.sidebar-menu .system').addClass('active');
$('.sidebar-menu .system .student').addClass('active');
$(".sidebar-menu .system").tree();
$(document)on('change','#streams', handleStreamChange(this));
handleStreamChange($('#streams')) // **Call this on page load, pass as this the streams dropdown**
});
function handleStreamChange(_this) {
$('#branches').html("<option value=''>-- Select --</option>");
$('#batches').html("<option value=''>-- Select --</option>");
$('.divAfter').hide();
$('.divBefore').show();
$('.semesterAfter').hide();
$('.semesterBefore').show();
$('.btnAdd').hide();
$('.btnExcel').hide();
$('.studList').hide();
if ($(_this).val() == '') {} else {
$.when($.streamSelection($(_this).val())).then($.listSemester($(_this).val()));
}
}
Try Jquery trigger function
$(document).ready(function() {
$( "#streams" ).trigger( "change" );
});
You can get more information about this here http://api.jquery./trigger/
Try this :
$(document).on('change', '#streams', function() {
// Your code
});
