I have Bootstrap dropdown button, I want get data when user click this dropdown button instead of I need load country list at page loading time, here is my code;
<div class="btn-group">
<input class="text-box single-line" data-val="true" data-val-required="The Country field is required." id="Country" name="Country" type="text" value="US" />
<a class="btn dropdown-toggle country" id="country" data-toggle="dropdown">
<span class="caret"></span>
</a>
<ul class="dropdown-menu countrys" role="menu" aria-labelledby="dropdownMenu">
//store country list
</ul>
</div>
I click dropdown button, it can't trigger jquery work, it seems Bootstrap don't allow custom dropdown function.
$(document).ready(function () {
$('#country').click(function () {
// Only call notifications when opening the dropdown
if (!$(this).hasClass('open')) {
$.ajax({
type: "GET",
url: "/getCountries",
async: false,
dataType: "script"
});
}
});
});
You can try to add the ajax request inside the dropdown-open event. something like this:
$('#myDropdown').on('show.bs.dropdown', function () {
// do something…
})
show.bs.dropdow-- This event fires immediately when the show instance method is called. The toggling anchor element is available as the relatedTarget property of the event.

i wrote some code to view my all showing events details using bootstrap modal popup when click read more button. but when i click read more button every response repeats same id.
this is my laravel code
#if(!empty($event))
#foreach($event as $value)
<!-- Single Blog Post -->
<div class="single-blog-post d-flex" id="event_tag">
<div class="post-thumbnail">
<img src="{{asset('images/'.$value->image)}}" alt="">
</div>
<div class="post-content">
<a class="post-title">
#if(strlen($value->title) <= 35)
{{$value->title}}
#else
{{substr($value->title, 0, 35) . '...'}}
#endif
</a>
<div class="post-meta d-flex justify-content-between">
<center><button id="event_button" class="post-cata cata-sm cata-success text_white" data-toggle="modal" data-target="#myModal">Read More</button></center>
</div>
</div>
<input type="hidden" name="event_id" id="event_id" value="{{$value->id}}"></div>
#endforeach
#endif
and this is javascript code to get id and show every id detail.
<script>
$(document).on("click", "#event_button", function() {
var id = $("event_id").val();
console.log(id);
$.ajax({
url: "/event/" + id + "/show",
dataType: "json",
success: function(html) {
$("#event_title").html(html.data.title);
}
});
})
</script>
every time repeats id no 2 when click each event read more button. how can i fix this?
Your code has some mistakes in html too. For example, has fixes ids in html.
'event_id'
'event_button'...
Try this...
<button id="event_button-{!! $value->id !!}" data-target="event_id-{!! $value->id !!}"
<input type="hidden" name="event_id" id="event_id-{!! $value->id !!}"
The code above will fixed the id issue.
Now let's to the JS code... Change the click event:
$(document).on("click", "button.post-cata", function() {
var id = $("#" . $(this).data("target").val();
...
Do you need to associate tags to work with the right value. Avoid to put fixes ids inside a php loop. The html id element must be unique in document.
So, has many ways to do this. In this case, the input hidden fild is not necessary. you can put the id in a attribute in the button tag too.
<button data-id="{!! $value->id !!}...
So in the jquery click event do:
var id = $(this).data('id');
It's more ease and clean.
give class name to button and add attribute to button
<button class="event_button post-cata cata-sm cata-success text_white" data-eventid="{{$value->id}}">Read More</button>
so no need to use hidden input id
now using jQuery :
$(document).on('click','.event_button',function(){
var event_id = $(this).attr("data-eventid");
$("#myModal").modal("show");
$.ajax({
url: "/event/" + event_id+ "/show",
dataType: "json",
success: function(html) {
$("#event_title").html(html.data.title);
}
});
});
Please find below my code:
Template of customer search form
<script type="text/x-kendoui-template" id="customer-search-view-template">
<div class="searchform" id="searchCustomer">
<form class="frmSearch">
<input name="searchTxt" data-bind="value: customerName" class="k-textbox" />
<button class="k-button" data-bind="click: searchClicked">Search</button>
<button class="k-button" data-bind="click: newClicked">New</button>
</form>
</div>
</script>
customer-search.js where loading above template and creating viewmodel object
$(function(){
var views = {};
templateLoader.loadExtTemplate("customer-search-view-template", "../views/customer-search-template.html");
var layout = new kendo.Layout($('#customer-search-view-template').html());
layout.render($("#main"));
// Create an observable view model object.
var customer = kendo.observable({
customerName: "John",
searchClicked: function() {
this.set("customerName", "Search clicked");
},
newClicked: function() {
this.set("customerName", "New clicked");
}
});
// Bind the view model to the personFields element.
kendo.bind($('#searchCustomer'), customer);
});
When I click the search button, the text is set in the textbox but this also refresh the page with ?searchTxt=Search+clicked in the address bar.
May I know why this button click refresh the page and how do I stop refreshing the page on button click ???
I would try and place the attribute 'type' for each like so:
<button type="button" class="k-button" data-bind="click: searchClicked">Search</button>
<button type="button" class="k-button" data-bind="click: newClicked">New</button>
The page thinks that each are performing a form submit action, but by placing the type attribute, you can access the event you intended for search. You may not need your form tags if you are not going to post any data, but rather just a js event handler. Good luck.
The reason is that you are inside a <form>, which has no settings (URL, method, etc), so the browser's default behavior is probably to perform a GET to the current URL (which is a refresh). You could just use <div> instead of <form> if you just want to execute that method.
I am using AngularJS v1.2.15 and angular-ui / ui-select. My select HTML is:
<div class="form-group col-md-3">
<div class="input-group select2-bootstrap-append">
<ui-select ng-model="modelOwner.selected" theme="select2" class="form-control">
<match placeholder="Select Owner">{{$select.selected.name}}</match>
<choices repeat="item in owner | filter: $select.search">
<span ng-bind-html="item.name | highlight: $select.search"></span>
</choices>
</ui-select>
<span class="input-group-btn">
<button ng-click="modelOwner.selected = undefined" class="btn btn-danger">
<span class="glyphicon glyphicon-trash"></span>
</button>
</span>
</div>
</div>
My call in controller is:
$scope.modelOwner = {};
OwnersFactory.query({}, function (data) {
$scope.owner = data;
});
My service code:
bootstrapApp.factory('OwnersFactory', function ($http,$state,serviceUrl,$resource,$log) {
return $resource(serviceUrl + 'owner/:id', {}, {
show: { method: 'GET', params: {}, isArray: false }
})
});
Now, in my form i can view the values only after entering at least a single character. I want this select dropdown to display values just by clicking on the dropdown (not by entering any character.)
Possible Solution: if i could load my state only after all the AJAX calls have been made.
Please help me out here.
if you are using ui-router you can use resolve on each state, so that the call is resolved before initializing the controller

I do not understand how I can validate a form with jquery validate to display the Submit button or not.
My javascript is as follows:
ko.bindingHandlers.jqValidate = {
init: function (element, valueAccessor, option) {
var element = element;
var validateOptions = {
ignore: [":hidden:not(required)"],
focusCleanup: true,
onsubmit: true
};
function displaySubmitButton() { // Remove/Add class to submit button
if ($('form').valid()) $('.toSave').show();
else $('.toSave').hide();
}
$('form').bind('onchange keyup onpaste', function (event, element) {
if ($('form').valid() === true && $(element).not('.resetForm')) $('.toSave').show();
else if ($(element).not('.resetForm')) $('.toSave').hide();
});
}
};
My form :
<ol class="MutColor13 mouseOver" data-bind="jqValidate: {}">
<li class="rightCol">
<strong>
<label for="iEmailReply"><asp:Literal runat="server" ID="lEmailReply" /></label>
</strong>
<input id="iEmailReply" name="EmailReply" type="text" tabindex="2"
class="MutColor13 email"
data-bind="value: communication.Message.ReplyEmail, valueUpdate: 'afterkeydown'"
required="required" />
</li>
<li class="leftCol">
<strong>
<label for="iEmailFrom"><asp:Literal runat="server" ID="lEmailFrom" /></label>
</strong>
<input id="iEmailFrom" name="EmailFrom" type="text" tabindex="1"
class="MutColor13 email"
data-bind="value: communication.Message.SenderEmail, valueUpdate: 'afterkeydown'"
required="required" />
</li>
<!-- and more form input -->
</ol>
My submit button :
<div class="buttonBlock rightButton" data-bind="fadeVisible: validateMessage()">
<a class="MutButton3 toSave" data-bind="click: saveMessage"><span class="MutButton3">submit</span></a>
</div>
when I type "$ ('form'). valid ()" in the firebug console, all error messages appear. I do not think the submit button is the problem because I have not clicked at this point
How do I enable the display of the error message from the input short change while allowing the display of the submit button if fields (and any other form fields in the page) if all fields are valid?
I was inspired by this question: jquery validate: IF form valid then show submit button
a working demo : http://jquery.bassistance.de/validate/demo/
but the button is displayed continuously
ok I think this could work:
http://jsfiddle.net/Ay972/10/
what I did :
$('form').bind('change oninput', function (event, element) {
console.log('formLive :: ', $(event));
if ($('form').valid() === true && $(element).not('.resetForm')) $('.toSave').show();
else if ($(element).not('.resetForm')) $('.toSave').hide();
});
the 'change oninput' seems to work.
I have a kendo mobile form that I will be using to capture some information from my users.
I would like to post the data to a web service or aspx(test page) using ajax. It seems like overkill to use MVVM for a form that the user fills out and there will be no reads/updates/deletes.
The ajax call happens but I cannot figure out how to post the data . Nothing goes over if i use $(this).serialize(). If I hard code some data, then it works.
There are going to be a lot of controls on the page and i hope i don't have to manually build the form data. I cannot add a <form> tag as it breaks the styling of the page.
If there is a more "kendo" way of doing this please show me how. Thanks
Here is what I have so far.
//Submit Form
function submit_form(e) {
$.post('TestPost.aspx', $(this).serialize(), function (data) {
// This is executed when the call to web service was succesful.
// 'data' contains the response from the request
alert(data);
}).error(function (xhr, ajaxOptions, thrownError, request, error) {
alert('xrs.status = ' + xhr.status + '\n' +
'thrown error = ' + thrownError + '\n' +
'xhr.statusText = ' + xhr.statusText + '\n' +
'request = ' + request + '\n' +
'error = ' + error);
});
e.preventDefault();
}
//Example of html controls
<div id="checks" data-role="view" data-title="Foo" data-layout="checklayout">
<ul data-role="listview" data-style="inset" data-type="group">
<li>Floor

<li>
<label for="Foo">
<input type="radio" name="Foo" id="FooOk" value="Ok" />

</li>
<li>
<label for="Foo2">

Here $(this) will give u only the button element. The easy way to do this is use the built in MVVM feature in Kendo UI Mobile. create an model as JS object and set data-model attribute of your view as this object. Now on click of the submit button, just send this object to your server using ajax. This way u are reducing the amount of data sent to the server.

I have used a PageMethod previously.
http://encosia.com/using-jquery-to-directly-call-aspnet-ajax-page-methods/
Would something like this help your cause?
Let's take an example of such a method in the code behind:
[WebMethod]
public static string MyMethod(string Id)
{
return string.Format("Thanks for calling me with id: " + Id);
}
Things to note: the method must be static and decorated with the [WebMethod] attribute.
And on the client side you could invoke this method using the jQuery.ajax() function like this:
$.ajax({
url: 'default.aspx/MyMethod',
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: JSON.stringify({ ID : ID }),
success: function (result) {
alert(result.d);
}
});
Make sure that in your WebForm you have actually added reference to the jQuery library before using it.
For example:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js" type="text/javascript"></script>
