Change Bootstrap dropdown selection using jquery

I have a bootstrap select dropdown.
I want to change the selection when I load the page. How can I write jquery for the same?
I've tried using $('.dnsType').toggle('Hostname') but that didnt work :(
This is my code:
<div class="row form-group">
<div class="btn-group dnsType <%= getColumnSize(editMode) %>">
<button class="btn btn-xs white dropdown-toggle" id="dnsType" type="button" data-toggle="dropdown" aria-expanded="true">
<span data-value="IP Address">IP Address</span><b class="caret"></b>
</button>
<ul class="dropdown-menu" role="menu" aria-labelledby="dnsType">
<li><a value="IP Address">IP Address</a></li>
<li><a value="Hostname">Hostname</a></li>
</ul>
</div>
<div class="<%= getColumnSize(editMode) %>">
<div class="form-horizontal">
<input type="text" name="ipAddress" class="ipAddress" data-name="IP Address" class="form-control" value="<%= controller.ipAddress %>">
<span class="validationErrorMessage"></span>
</div>
</div>
</div>

Bootstrap dropdowns are not like <select> elements. They don't have "selections". It is just a dropdown that shows a list of links when you click the button. I'm guessing that you just want to change the text for that button when the page loads. Here is how you can do that:
$("#dnsType span").text("Hostname").attr('data-value','Hostname');
This sets the text to "Hostname" and changes the data-value attribute to "Hostname"

jQuery find previous button by ID (which will have different names)

Hey all I am trying to get the previous button so that I can change its text to something else once someone selects a value from a select box.
<div class="input-group">
<div class="input-group-btn search-panel">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
<span id="search_concept">Type</span> <span class="caret"></span>
</button>
<ul class="dropdown-menu" id="dd1" role="menu">
<li>For Sale</li>
<li>Wanted</li>
</ul>
</div>
<div class="input-group-btn search-panel">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
<span id="search_concept">Location</span> <span class="caret"></span>
</button>
<ul class="dropdown-menu" id="dd2" role="menu">
<li>Somewhere</li>
<li>Elsewhere</li>
</ul>
</div>
<input type="text" class="form-control" name="x" placeholder="Search term...">
</div>
$('.search-panel #dd1, .search-panel #dd2').find('a').click(function(e) {
e.preventDefault();
var param = $(this).data("info");
$(this).prev().find('#search_concept').text($(this).text());
});
So the click event starts from THIS which is the a href="#" data-info="blah1">[value here]< /a> tag. So I am trying to go back to the < button> tag so that I can change the text Type to whatever was selected.
I've tried:
$(this).prev().find('#search_concept').text($(this).text());
and
$(this).prev().prev().find('#search_concept').text($(this).text());
and
$(this).prev().prev().children().find('#search_concept').text($(this).text());
and
$(this).prev().children().find('#search_concept').text($(this).text());
And I can't seem to find it....
fixed
$('.search-panel #dd1, .search-panel #dd2').find('a').click(function(e) {
e.preventDefault();
var param = $(this).data("info");
$(this).parents('.search-panel').find('button').html($(this).text() + ' <span class="caret"></span>');
});

The following snippet uses jQuery's .parents to locate a button.
$(this).parents(selector) will find any parent elements that have the specified selector.
Then .find(selector) will search that parent element for the specified selector.
Then you can assign that to a variable and use the element.
$('.search-panel #dd1').find('a').click(function(e) {
e.preventDefault();
var param = $(this).data("info");
var text = $(this).text();
// Assign element to variable for later manipulation
var $button = $(this).parents('.search-panel').find('button');
// eg: Replace button text (replaces all content including html)
// $button.text(text)
// eg: Find another element inside $button and replace the text
// $button.find('#search_concept').text(text)
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="input-group">
<div class="input-group-btn search-panel">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
<span id="search_concept">Type</span> <span class="caret"></span>
</button>
<ul class="dropdown-menu" id="dd1" role="menu">
<li>For Sale</li>
<li>Wanted</li>
</ul>
</div>
<input type="text" class="form-control" name="x" placeholder="Search term...">
</div>

You simply can't have multiple SAME ids.
$(this).parents().find("button #search_concept").text($(this).text());

You have duplicated ids which can make things messy. I would change concept of relaying on id to some other selectors, e.g classes:
And so such way you can treat search-panel group as a widget, and javascript going to be rewritten as:
$('.search-panel').each(function() {
var search_concept = $(this).find(".search_concept");
$(this).find('a').click(function(e) {
e.preventDefault();
var param = $(this).data("info");
search_concept.text($(this).text());
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="input-group">
<div class="input-group-btn search-panel">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
<span class="search_concept">Type</span> <span class="caret"></span>
</button>
<ul class="dropdown-menu" class="dd" role="menu">
<li>For Sale</li>
<li>Wanted</li>
</ul>
</div>
<div class="input-group-btn search-panel">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
<span class="search_concept">Location</span> <span class="caret"></span>
</button>
<ul class="dropdown-menu" class="dd" role="menu">
<li>Somewhere</li>
<li>Elsewhere</li>
</ul>
</div>
<input type="text" class="form-control" name="x" placeholder="Search term...">
</div>
This approach will arguably improve portability.

How to change icon in Bootstrap collapse for multiple requirments

I have used Bootstrap collapse for three different div for different requirments.
First Collapse div : I need to change "glypicon-left and bottom icon" of "showing text and hide".
<div class="col-md-12">
<span class="badge">
<span>0</span>
</span>
<span> Function</span>
<a data-toggle="collapse" data-parent="#accordion" href="#collapse1" class="fb_down_arrow">
<span class="glyphicon glyphicon-triangle-bottom"></span>
</a>
</div>
<ul class="fb_list_option collapse in" id="collapse1">
<li>
<input type="checkbox" id="c5" name="cc">
<label for="c5"><span></span>Corporate Real Estate</label>
</li>
</ul>
Second Collapse div : I need to change "glypicon-plus and minus" icon of "showing text and hide".
<li>
<input type="checkbox" id="c92" name="cc">
<label for="c92"><span></span>Construction (###)</label>
<a href="" data-toggle="collapse" data-target="#fb_plus_one" class="" >
<span class="glyphicon glyphicon-plus fb_list_plus_arrow"></span>
</a>
<ul id="fb_plus_one" class="collapse in" aria-expanded="true">
<li>
<input type="checkbox" id="c01" name="cc">
<label for="c01"><span></span>Child 1</label>
</li>
</ul>
</li>
Third Collapse div : I need to change "glypicon-left and bottom icon" and also change Text of "show more" , "less more" of showing text and hide.
See more detail <span class="glyphicon KB_glyphicon glyphicon-triangle-left"></span>
<div class="row collapse in" id="demo1" aria-expanded="true">
</div>
Script:
I am using below script archiving first collapse div requirement.kindly advise how to to archive second & third collapse.
// Collapse Start
$('.collapse').on('shown.bs.collapse', function(){
$(this).parent().find(".glyphicon-triangle-left")
.removeClass("glyphicon-triangle-left")
.addClass("glyphicon-triangle-bottom");
}).on('hidden.bs.collapse', function(){
$(this).parent().find(".glyphicon-triangle-bottom")
.removeClass("glyphicon-triangle-bottom")
.addClass("glyphicon-triangle-left");
});
// Collapse End

Please try this
$('.collapse').on('shown.bs.collapse', function(){
e.stopImmediatePropagation()
$(this).parent().find(".glyphicon-triangle-left").first().removeClass("glyphicon-triangle-left").addClass("glyphicon-triangle-bottom");
}).on('hidden.bs.collapse', function(){
e.stopImmediatePropagation()
$(this).parent().find(".glyphicon-triangle-bottom").first().removeClass("glyphicon-triangle-bottom").addClass("glyphicon-triangle-left");
});

Set focus on the first input field on dropdown toggle through angular js

<th class="dropdown" id="header">
<span>Label</span>
<span id="filter" class="sort_row glyphicon glyphicon-filter dropdown-toggle" data-toggle="dropdown" ></span>
<ul class="dropdown-menu filter-dropdown" role="menu">
<li >
<span class="input-group value">
<input type="text" id="inputField1" name="inputField1" class="form- control" ng-model='inputFieldFirst'/>
</span>
</li>
</ul>
</span>
</th>
Here I want to focus on the input field when the filter is clicked and the dropdown opens.
Is there a way in which I dont have to use the id of the input field and set focus on the input that is present in the dropdown

I probably try this.
$( "#filter" ).click(function() {
$( ".dropdown-menu input:first-child()" ).focus();
});

AngularJS form validation on a bootstrap dropdown

Is it possible to add AngularJS to a Boostrap dropdown (not a <select/>, but rather the Javascript component)? This is what I have:
<div class="form-group has-feedback" ng-class="{'has-error': editorForm.example.$invalid && !editorForm.example.$pristine, 'has-success': editorForm.example.$valid && !editorForm.example.$pristine}">
<label for="example">Example</label>
<div class="dropdown" id="example" style="width: 90%">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdown"
data-toggle="dropdown">
{{exampleLabel}}
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1">
<li data-ng-repeat="example in examples" role="presentation"><a
role="menuitem" tabindex="-1"
data-ng-click="selectExample(example)"
href="javascript:void(0);">{{example.label}}</a>
</li>
</ul>
</div>
$scope.selectExample = function(val) {
$scope.example = val;
}
Is there a way for me to programatically set the validity in selectExample?

Add this hidden text box:
<input type="text" name="exampleLabel" ng-model="exampleLabel" hidden required />
and add this validation after the dropdown
<span class="text-danger" ng-show="myForm.exampleLabel.$error.required">
validation message
</span>

Add input type="hidden":
<form class="form-validation" name="actin_form">
<div uib-dropdown>
<input type="hidden" name="nameVal" ng-model="nameValModel" required/>
<button type="button" ng-class="{'input-error': actin_form.nameVal.$invalid}" class="btn" uib-dropdown-toggle>
<span>{{nameValModel}}</span>
</button>
<ul class="dropdown-menu">
<li ng-repeat="type in list" class="text-wrap">
<span>{{type.name}}</span>
</li>
</ul>
</div>
</form>

This work for me.hope you can get some idea.
<style>
.dropdown-has-error{
border-color: #a94442;//bootsrtap warning color
}
</style>
add ng-class directive to the dropdown button
ng-class="{'dropdown-has-error' : example == ''}
in the controller
$scope.example = '';
$scope.selectExample = function(val) {
$scope.example = val;
}
or you can check condition as in the above post,
ng-class="{'dropdown-has-error' : myForm.exampleLabel.$error.required}
