Is there an option to allow a user to enter their own value into a #Html.DropDownListFor?
I tried making it content editable but no luck.
You can add with javascript like below:
$('#btn').click(function(){
var mySelect = $('#mySelect');
mySelect.append(
$('<option></option>')
.val($('#txtval').val())
.html($('#txtname').val()));
});

I'm using a checkbox to create a toggle switch as shown in this tutorial
The switch lives in a form where questions can be added dynamically. On submission the form posts as array of each answer back to the page to be processed however as the off switch doesn't pass a value back to the form the answers get out of sync with the answers for the other text fields. Is there any way to set a value for the off switch, i.e. when a check box is left unchecked?
I've tried to use the following to set my off checkboxes to off however it just seems to animate all the switches to on on form submission, anyone any ideas as to what I'm doing wrong?
$('form').submit(function(e){
var b = $("input:checkbox:not(:checked)");
$(b).each(function () {
$(this).val(0); //Set whatever value you need for 'not checked'
$(this).attr("checked", true);
});
return true;
});
You probably want to use Javascript to set a value for each checkbox "switch" in one of two ways:
Option 1: in the html of the switch elements/checkboxes, set the value attribute to zero by default. Then add a javascript click handler for the toggle to check its current value and toggle to the opposite state/value.
Option 2: add Javascript to the form's submit handler (on submit) that checks for any switch elements which have no values and set them to zero before processing form.
Either way should pass a value at all times, and your form should be able to keep track of all input states.
This snippet did the trick, as Anson suggested this finds all the checkboxes and sets them to either on or off on form submission:
$('form').submit(function () {
$(this).find('input[type="checkbox"]').each( function () {
var checkbox = $(this);
if( checkbox.is(':checked')) {
checkbox.attr('value','1');
} else {
checkbox.after().append(checkbox.clone().attr({type:'hidden', value:0}));
checkbox.prop('disabled', true);
}
})
});
I have an array of divs which can be selected (change background colour on click to signify that to the user).
I want a way to submit the ids of all of these divs to my app, though can't see a 'nice' way of doing this; at the moment the only thing I can see to do is have a button that onclick triggers a javascript function that gets the id's and sends them back to my server in a POST.
Is there a way of creating a multiple select input on a form which uses divs instead of checkboxes or a multi-select list, or a better way of doing what I'm attempting?
Assuming you add the class selected when a user 'selects' the div:
var data = {};
$(".classOfDivs.selected").each(function(){
data[$(this).prop('id')] = 'true';
}
$.ajax({
url : 'ajaxPage.php',
type : 'POST',
dataType : 'text',
cache: false,
data: data,
success : function(text){alert('Saved: '+text);},
error: function(){alert('Did not reach server');}
});
Use the success function to process the returned text as needed. dataType can be changed to html, JSON, etc. See the .ajax() documentation.
Have a hidden input for each div, all with the same name but with a different id. When a div is clicked update the corresponding hidden input with the id. Then when you submit through a standard form POST all of those values will be available through the name you specified.
Since this is an app, what you could do is store everything in HTML5 localstorage using the JQuery javascript library.
Here's how to do it step by step:
Create a jquery array
on click, get div id and store it in the array with a key/value pair
if clicked again, remove it from the array
have some event listener like a "submit" button to store the value of your array to localstorage
Here is a jsfiddle I had that has exactly what you are talking about: http://jsfiddle.net/CR47/bqfXN/1/
It goes into a little more depth but the jquery should be exactly what you need.
The reason this is better than submitting with POST or using ajax is because since you say this is an app, you will be able to use this method offline, where as post or ajax would require a connection to a server running php.
var skinCare=[]; //the array
$('.skinCare').click(function(){ //onclick
var value = event.target.className.split(" ")[0]; //get classname, you would get id
var index = skinCare.indexOf(value); //gets where the location in
//the array this code is
if($(this).hasClass('selected')){ //when a div is clicked it gets
//$('.skinCare').removeClass('selected'); //the class "selected" and adds
skinCare.splice(index, 1); //to array, then another click
} else if($.inArray(value, skinCare) == -1){ //removes it from array
skinCare.push(value);
}
});
$('.submitbutton').click(function(){
localStorage.setItem('Skin Care', JSON.stringify(skinCare));
});
In the the ckeditor init, to remove dialog tabs, it is possible to do something like:
CKEDITOR.on( 'dialogDefinition', function( ev )
{
// Take the dialog name and its definition from the event data.
var dialogName = ev.data.name;
var dialogDefinition = ev.data.definition;
// Check if the definition is from the dialog we're interested in
if ( dialogName == 'link' )
{
dialogDefinition.removeContents( 'advanced' );
}
});
This will remove the "advanced" tab from the link dialog.
It also possible to remove specific attributes from a tab, doing something like:
var infoTab = dialogDefinition.getContents( 'info' );
// Remove unnecessary widgets from the 'Link Info' tab.
infoTab.remove( 'linkType');
infoTab.remove( 'protocol');
So this works fine, but my problem is I could not find a detailed list of the attributes names, like 'linkType' or 'protocol' in the example above.
Basically I would like to remove, from the image dialog for example, the width, height, the css class and id from the advanced tab etc, but I cannot find a the names of these attributes in the ckeditor documentation, does someone know where I can find this ?
Or give a list?
You can use the Developer tools plugin as explained in the HowTos: http://docs.cksource.com/CKEditor_3.x/Howto/Field_Names
I am trying to build my first web application. In my app I need to have a settings panel, but I have no idea how to do it. I've been searching the web and came across a HTML5 localStorage, which I believe might be the best way to do the things. But the problem is I have no idea how to use it.
<input type='text' name="server" id="saveServer"/>
How can I save data from input to localStorage when user clicks the button? Something like this?
<input type='text' name="server" id="saveServer"/>
<button onclick="save_data()" type="button">Save/button>
<script>
function saveData(){
localStorage.saveServer
}
</script>
The localStorage object has a setItem method which is used to store an item. It takes 2 arguments:
A key by which you can refer to the item
A value
var input = document.getElementById("saveServer");
localStorage.setItem("server", input.val());
The above code first gets a reference to the input element, and then stores an item ("server") in local storage with the value of the value of that input element.
You can retrieve the value by calling getItem:
var storedValue = localStorage.getItem("server");
This worked for me. For setting I placed .value behind the var and called the var in the setItem:
var input = document.getElementById('saveServer').value;
localStorage.setItem('server', input);
For getting the text back:
document.getElementById('saveServer').value = localStorage.getItem('server');
Using HTML
I want to use 2 checkbox, when i click the check box 1 then it will redirect to another page, when i click the check box 2 then it will redirect to another page.
How to make a code in HTML
Need Code Help
First of all checkboxes are not supposed to be used for redirection purpose, however if you really want to do that, you can go about something like this:
var el = document.getElementById('checkbox1_id');
el.onclick = function(){
document.location.href = 'somepage.html';
};
var el2 = document.getElementById('checkbox2_id');
el2.onclick = function(){
document.location.href = 'somepage2.html';
};
