I am working on Asp.net MVC.
i am using regular html
<label for="txtbox1" > User Name</label>
<input type="text" id="txtbox1" name="text" class="water"/>
I want to display Cursor before text and Text both when page load. When user start writting in text box at that time "User Name" removed.
You need to use javascript for this. If you are using jquery you could:
$(function() {
$('#txtbox1').focus();
});
And if you want to do this with plain javascript:
window.onload = function() {
var textbox = document.getElementById('txtbox1');
if (textbox != null) {
textbox.focus();
}
};
UPDATE:
If you want the text to disappear when the user starts typing you may try the following:
$('#txtbox1').keypress(function() {
if (!$(this).data('dirty')) {
$(this).val('').data('dirty', true);
}
});

I'm using DirtyForms and $.blockUI plugin, the latter to change pages when clicking on links (in my app, some pages take a couple of seconds more to load and a visual feedback is fine).
When I change field content and then click any link, DirtyForms is triggered: but when I cancel the process to stay on the page, $.blockUI starts its game, resulting in a stuck page
$('form[method="post"]').dirtyForms();
$('a').on('click', function(){
$.blockUI();
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.dirtyforms/2.0.0/jquery.dirtyforms.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.blockUI/2.70/jquery.blockUI.min.js"></script>
<p>Change the field content to activate DirtyForms, then click on the link.<br>
When the popup appears, click on "cancel" to stay on the page.<br>
Watch blockUI getting fired as the link is going to be followed</p>
<form action="#" method="post">
<input type="text" name="username" required>
<button type="submit">send</button>
</form>
click me after changing field content
Please, any solution?
EDIT: I also tried with stay.dirtyforms and afterstay.dirtyforms events, but they have no effect. defer.dirtyforms seems to work but the event is triggered twice (I put a console.log() to check) and I am not sure this is the way to go...
I've edit my answer: I've added some line of code to disable first the onbeforeunload dialog alert, taken from here. And at the end a link to an answer with another idea you can try.
My idea: you have to prevent the default link action and use the $.blockUI Modal Dialogs methods to open a custom dialog, then catch the link attribute href from the link put it inside a variable and use the variable value for the #yes button of the dialog.
See if this solution can meet your needs
/* beforeunload bind and unbind taken from https://gist.github.com/woss/3c2296d9e67e9b91292d */
// call this to restore 'onbeforeunload'
var windowReloadBind = function(message) {
window.onbeforeunload = function(event) {
if (message.length === 0) {
message = '';
};
if (typeof event == 'undefined') {
event = window.event;
};
if (event) {
event.returnValue = message;
};
return message;
}
};
// call this to prevent 'onbeforeunload' dialog
var windowReloadUnBind = function() {
window.onbeforeunload = function() {
return null;
};
};
var linkToFollow; // href to follow
$('form[method="post"]').dirtyForms();
$('a').on('click', function(e){
e.preventDefault();
windowReloadUnBind(); // prevent dialog
$.blockUI({ message: $('#question'), css: { width: '275px' } });
linkToFollow = $(this).attr('href');
});
$('#no').click(function() {
$.unblockUI();
return false;
});
$('#yes').click(function() {
$(window.location).attr('href', linkToFollow);
});

click me after changing field content
<div id="question" style="display:none; cursor: default">
<h6>Would you like to contine?.</h6>
<input type="button" id="yes" value="Yes" />
<input type="button" id="no" value="No" />
</div>
Other idea taken from another answer: Other idea would be to make a simple jQuery.ajax({}) call before return value in beforeunload as seen in this answer
Have the following READONLY textbox:
#Html.TextBoxFor(model => model.ClientNumber, new {#readonly = "readonly", #class ="message-label"})
and Save button:
<button type="submit" id="btnSave" name="Command" value="Save">Save</button>
When user clicks on Client Number text box and hits Enter, then submit behavior is invoked and next page is displayed after data is saved to the database.
How to change this, so that hitting Enter while in this field does nothing, similar to how page behaves for a usual label?
You can do this with a little bit of javascript, handling keydown event and checking whether Enter was hit:
$(document).ready(function() {
$('input[name=ClientNumber]').keydown(function(e) {
if (e.keyCode === 13) {
e.preventDefault();
return false;
}
});
});
I´ve been struggling to make my Kendo Datepicker without user-text-input and the only solution I´ve come up with was making the tag "readonly". However I want to be able to select the date from the selector with the mouse without being able to input text directly to the picker, therefore making the datepicker readonly but selectable.
Any ideas how?
<div>
#(Html.Kendo().DatePicker()
.Start(CalendarView.Year)
.Name("DatePicker")
.Value(DateTime.Now.AddDays(-365))
.Max(DateTime.Now)
.HtmlAttributes(new { style = "width: 125px;" })
.Events(e => e.Change("onDateChange")))
</div>
After a while I found a very simple solution using javascript. I simply declared a script that prevents any user input without disabling or making the input readonly. Something like this:
$("#inputId").keypress(function (evt) {
var keycode = evt.charCode || evt.keyCode;
if (keycode == 9) { //allow Tab through
return true;
} else {
return false;
}
});
It was easier than I thought :)
########### EDITED ####################
As suggested in a comment, it is probably not good practice to suppress all the keystrokes so I will paste almost the same code but suggesting that I open the datePicker instead (but still kind of suppressing the user text input as well).
$("#inputId").keypress(function (evt) {
var keycode = evt.charCode || evt.keyCode;
if (keycode == 9) { //allow Tab through
return true;
} else {
// Allow the datepicker to open instead
var datePicker = $("#inputId").data("kendoDatePicker");
datePicker.open();
return false;
}
});
You can do something like this:
#(Html.Kendo().DatePicker().Name("FollowUpDate").HtmlAttributes(new{onkeydown="javascript:return false;" }))
when someone clicks the datepicker it returns false hence does not allow to type anything while it still remains selectable.
If you want to just select data from opening calendar which kendoDatePicker show you but user not allow to enter date

<link href="http://cdn.kendostatic.com/2015.1.408/styles/kendo.default.min.css" rel="stylesheet" />
<input type="text" onkeydown="return false" placeholder="Enter Date" class="DatePicherKendo" />
<script src="~/bower_components/DataPicker-Kendo/JalaliDate.js"></script>
<script src="~/bower_components/DataPicker-Kendo/kendo.web.js"></script>
$(".DatePicherKendo").kendoDatePicker();
Add a maxlength attribute of 0 in HtmlAttributes.
I am new to jquery mobile. In my UI, one text box and one select menu are there. Initially select menu is empty.If the textbox value is more than 1 then some data is added to the select menu otherwise select menu is empty. For this, i am calling the function at the onchange of select menu but it is not working. Please can anybody help me.
Edit:
Ex:
$('#Goal_Time').bind( "focus", function(event, ui)
{
if(Goal_WeightVar.val() > 0)
{
Goal_WtVar = Math.abs(weightVar.val() - Goal_WeightVar.val());
Min_DurationVar = Math.round(Goal_WtVar * 2.2);
for(var i=0;i<10;i++)
{
$('#Goal_Time').append('<option value=Min_DurationVar>Min_DurationVar</option>');
}
}
});
thanks
Well Kinda working example:
http://jsfiddle.net/v5DC3/5/
JS
$('#Goal_WeightVar').live('change', function() {
var weightVar = 0; // for testing only
var goalWeightVar = $('#Goal_WeightVar').val();
if(goalWeightVar > 0)
{
Goal_WtVar = Math.abs(weightVar - goalWeightVar);
Min_DurationVar = Math.round(Goal_WtVar * 2.2);
for(var i=0;i<10;i++)
{
$('#Goal_Time').append('<option value='+Min_DurationVar+'>'+Min_DurationVar+'</option>');
}
$('#Goal_Time').listview('refresh');
}
});
HTML
<div data-role="page" id="Goal_Time_Page">
<div data-role="content">
<label for="Goal_WeightVar">Goal Weight:</label>
<input type="text" name="Goal_WeightVar" id="Goal_WeightVar" value="" />
<label for="Goal_Time" class="select">Goal Time:</label>
<select name="Goal_Time" id="Goal_Time">
<!-- Add options here -->
</select>
</div>
</div>
You will need to tweak it
As it says in the docs of jQuery Mobile, you have to tell the select menu to update it's contents by calling $('select').selectmenu();
If it still doesn't work you'll have to post a little sample code so I can have a look at it.
Edit:
Actually, that's not even necessary. If you have an empty <select id="to-append"></select>, you can just add options via $('#to-append').append('<option value="a">A</option>')!
The onchange event of the select is probably not the right event to do this though. The select will not change as long as it's empty, thus your event will never get triggered. Try the blur event of the text box.

I've been looking at the:
data-filter="true"
option for filtering a list based on what is entered into a search box using Jquery mobile.
I'd like to do the same except hook in the ability to use an ajax get() to populate the list. Does anyone know how to go about doing this or an example anywhere of it being achieved. I've not seen anything on the JQ mobile site.
Thanks.
I couldn't find anything built in that does what you ask, but I was able to achieve this using a simple ajax request and manually filling the list. I started with a text box for the search field, and an empty ul
<div data-role="fieldcontain">
<label for="search">Search:</label>
<input type="search" name="search" id="search" value=""/>
</div>
<ul id="results" data-role="listview">
</ul>
This script block will send an ajax request after each key press, it might be better to add a delay though. It will abort the previous request if still loading and the person types another key. Not perfect, but its a start.
<script>
var last, last_xhr;
var x = $('#search').live('keyup change', function () {
if (last == $(this).val()) return;
last = $(this).val();
$.mobile.showPageLoadingMsg();
if (last_xhr) {
last_xhr.abort();
}
last_xhr = $.get('/Search', { q: last }, function (data) {
last_xhr = undefined;
var list = $('#wines').empty();
$.each(data, function (i, val) {
var el = $('<li data-theme="c" />');
el.append($('' + val.Name + ''));
list.append(el);
});
list.listview('refresh');
$.mobile.hidePageLoadingMsg();
});
});
</script>
The most important bit is calling refresh otherwise it doesn't apply the theme.
list.listview('refresh');
