in the snippet it's showing an error, but on my console in my code it's not returning any error
the form
it should be showing on the right side of this option (image above)

You just have to remove the change() statement at the end of your change event listener. To initially hide the divs you could simply use the following line from your event handler:
$(".hide").hide();
Working example
$('#select_service').change(function() {
var select = $(this).find('option:selected').val();
console.log(select);
$(".hide").hide();
$('#' + select).show();
});
$(".hide").hide();

Hiding select option based on value that i choose

So i'm having a simple code like this
<div class="form-group form-material floating">
<select class="form-control" name="first" id="first">
<option value="opt1">First Option</option>
<option value="opt2">Second Option</option>
</select>
<label class="floating-label" for="inputStatus">Option</label>
</div>
and
<div class="form-group form-material floating">
<select class="form-control" name="second" id="second">
<option value="val1">First Value</option>
<option value="val2">Second Value</option>
<option value="val3">Third Value</option>
<option value="val4">Fourth Value</option>
</select>
<label class="floating-label" for="inputStatus">Option</label>
</div>
What I am trying to do is when i choose 'opt1' i want the other select only show 'val2, val3, val4' and if i choose 'opt2' i want the other select only show 'val1, val2, val4' .. how do i do that ?

$("#first").on('change', function(){
if(this.value == 'opt1')
{
$(".op3").removeClass("hidden");
$(".op1").addClass("hidden");
}
else if(this.value == 'opt2')
{
$(".op1").removeClass("hidden");
$(".op3").addClass("hidden");
}
});
.hidden{display:none !important;}
<div class="form-group form-material floating">
<select class="form-control" name="first" id="first">
<option value="opt1">First Option</option>
<option value="opt2">Second Option</option>
</select>
<label class="floating-label" for="inputStatus">Option</label>
</div>
<div class="form-group form-material floating">
<select class="form-control" name="second" id="second">
<option class="op1" value="val1">First Value</option>
<option value="val2">Second Value</option>
<option class="op3" value="val3">Third Value</option>

Reload the bootstrap3 modal with dynamic data

I have a modal which initially has two <div> elements inside. But users can dynamically add additional <div> elements also.
What I want to do is to show only the default two <div>s each time modal is closed and reopened.
I tried the following:
$('#modal').on('show.bs.modal', function () {
$(this).removeData('bs.modal');
});
It did not help.
How can I do this?
Initial modal body:
<div class="modal-body">

Basically, it has three main parts:
<div class="row" id="leg-1">
....
</div>
<hr>
<div class="row" id="leg-2">
....
</div>
<button>Add Leg</button>
The first two divs are initial defaults. When a user presses a Add Leg button, another div with id leg-3 (and so on.) is inserted into the template.

Add a class to the added <div>, ie. '.addedDivClass',
Then use jQuery .remove() to remove the elements when you show the modal.
$('#modal').on('show.bs.modal', function () {
// Get the added divs within the modal and remove them
$('.addedDivClass', this).remove();
});
Read more about remove() here.

try the following:
$('#modal').on('show.bs.modal', function () {
// Get the added divs within the modal and remove all except the first 2
$('div[id^="leg"]').not('#leg-1,#leg-2').remove();
});

$(this).closest(("select[name*='FIELD2']") not working

I have this form:
<div id="div_id_form-0-FIELD1" class="form-group">
<label for="id_form-0-FIELD1" class="control-label col-sm-2">
Amount Type
</label>
<div class="controls col-sm-3">

<option value="d" selected="selected">Dollars</option>
<option value="p">Percent of</option>
</select>
</div>
</div>
<div id="div_id_form-0-FIELD2" class="form-group">

<option value="g">Gross Pay</option>

</select>
</div>
</div>
I haveFIELD1 in ($this), I want to get FIELD2. This is not getting it for me:
$(this).closest(("select[name*='FIELD2']")

Use the .next() method, like so:
$(this)
.closest("div.form-group")
.next("div.form-group")
.find("select[name*='FIELD2']");

Hide And show html tab with a drop down menu

<div class="controls">
<select id="" name="Scholarship info">
<option value="">select</option>

</select>
</div>
and if we select yes then show that options otherwise if we select no ..not show below options....
<div class="controls">
<select id="" name="Bank name">
<option value="">select</option>
<option value="state bank">State bank</option>
<option value="Canera Bank">Canera bank</option>
</select>
</div>
<div class="controls">
<select id="" name="Branch name">
<option value="">select</option>
<option value="amethi">amethi</option>
<option value="lucknow">lucknow</option>
</select>
</div>
<div class="controls">
<select id="" name="account number">
<input type="text" class="span6 typeahead" name="acoountnumber" placeholder="account number" value="<?php echo
set_value('accountnumber'); ?>" />
</div>

LIVE DEMO
$(document).ready(function() {
$("select[name='Bank name']").hide();
$("select[name='Branch name']").hide();
$("select[name='account number']").hide();
$("input[name='acoountnumber']").hide();
});
$("select[name='Scholarship info']").change(function() {
var selectedVal = $(this).val();
if(selectedVal == 'yes') {
$("select[name='Bank name']").show();
$("select[name='Branch name']").show();
$("select[name='account number']").show();
$("input[name='acoountnumber']").show();
} else {
$("select[name='Bank name']").hide();
$("select[name='Branch name']").hide();
$("select[name='account number']").hide();
$("input[name='acoountnumber']").hide();
}
});

If you add an extra class, withScholarship to the divs you want to show and hide, it is gets even easier. See this JSFiddle
<div class="controls">
<select id="" name="Scholarship info">
<option value="">select</option>
<option value="yes">yes</option>
<option value="no">no</option>
</select>
</div>
<div class="controls withScholarship">
<select id="" name="Bank name">
<option value="">select</option>
<option value="state bank">State bank</option>
<option value="Canera Bank">Canera bank</option>
</select>
</div>
<div class="controls withScholarship">
<select id="" name="Branch name">
<option value="">select</option>
<option value="amethi">amethi</option>
<option value="lucknow">lucknow</option>
</select>
</div>
<div class="controls withScholarship">
<input type="text" class="span6 typeahead" name="acoountnumber" placeholder="account number" value="121"/>
</div>
<script type="text/javascript">
$(".withScholarship").hide();
$("select[name='Scholarship info']").change(function() {
var flag = $(this).val() == "yes";
$(".withScholarship").toggle(flag);
})
</script>
