Configuration form with a custom control in leaflet

I'm trying to create a custom control using leaflet; here you can see the jsfiddle: https://jsfiddle.net/1tca13f3/
When the user clicks on the submit button, i need to read the value from the dropdown and the one from the text field.
This...
L.DomEvent.on(this._container, 'click', this._doSomething, this);
...as predictable, doesn't work.. and I can't read the values from the input fields. How can I do this?

The main issue you are having is that you are just alerting the string 'clicked' in your _doSomething() function. You need to look up all the values and then you can do what ever you want with those values. Here is some quick code that will at least get you going in the right direction.
_doSomething: function(event){
if(event.target.className === 'leaflet-control-opt-submit') {
var select = document.querySelector('.leaflet-control-opt-dropdown');
var input = document.querySelector('.leaflet-control-opt-input');
console.log(select.value, input.value)
}
}
it first checks to make sure the event.target is the submit button if it is it looks up the values from the inputs and for now we just console.log() them you can do whatever you want from then on with the values.

Mvc Telerik grid cancel cell changes when input invalid

I am facing a small problem regarding input validation in mvc telerik grid.
I have it set to batch editting and I'm modifing the cells in an InCell mode.
Now whenever a user enters an invalid value in one of the inputs(Telerik's comboboxes/autocompletes), I'd like to display a message that
the entered value is iligal(this far I've managed on my own).
In addition to the message I'd like to revert the cell's value to it's previus value before
the user input.
So far I've tried:
grid.CancelCell(this);
$('#grid .t-grid-edit-cell input[type="text"]').value or innerText = prevVal;
The closest so far was e.newVal = e.oldVal, although it sometimes throws me a wierd exception in the jquery scripts or displays the combobox's drop down.
All the validatios and things I've tried are from the grid's client event OnSave()

It's same like what i searched before and I have solution for you.
On your OnSave() method has event like OnSave(e) and that 'e' carry all the elemnts and functions inside in my example after validation if not ok i can change that value to old value. Also you can use inspecter element log to look up what is inside 'e'
function onSave(e){
if(!validation)
{
///
}
else
{
e.cell.firstChild.value = "0"; // that is my edited cell
}
}

Using JQuery MaskInput Plugin with a SSN Field

I am trying to use the JQuery MaskInput plugin on a SSN field but I dont see anyway to make it display "***-**-****" after the user leaves the fields.
Did anyone get this working>

I havent tested this, but it may get you headed in the right direction. The masked input plugin has a completed function that can be called when the user has finished entering their value. You can use it to grab the value and store it in a hidden field to retain it and replace the current text with whatever you desire.
var $txt_SNN = $("#txt_SSN");
$txt_SNN.mask("999-99-9999", {
completed: function() {
$('#hdf_SNN').val($txt_SNN.val());
$txt_SNN.val("999-99-9999");
}
});

$txt_SNN.mask("999-99-9999").blur(function() {
$(this).attr('type', 'password');
});`
This should do it. Although I didn't test it.

Change disabled select(dropdownlist) based on another select(dropdownlist) value

Basically what I'm trying to do is self-explanatory in the title. Here's a snippet of code which enables the dropdown/select so it can be changed via client, but it will not disable after change:
function setLocVals(passedVal) {
$('#DropDownList1').removeAttr("disabled");
$('#DropDownList1').val(passedVal);
$('#DropDownList1'').attr("disabled", "disabled");
}
Is this even possible? Or am I looking at this completely the wrong way?
I could change to a textbox, but this is a dropdown containing US states. If there's a record for the user then the selection is restricted for the user, if no record exists, then they can select.

Just put a condition when you have to disable. See this fiddle
Use this approach.
First set the value in option.
Then retrieve the current value of the option and check if it is set to the one than you have passed then put the condition to disable else not
function setLocVals(passedVal) {
$('#DropDownList1').val(passedVal);
var value = $('#DropDownList1').val();
if(value == passedVal){
$('#DropDownList1').attr("disabled", "disabled");
}
}

set value to jquery autocomplete combobox

I am using jquery autocomplete combobox
and everything is ok. But I also want to set specific value through JavaScript like $("#value").val("somevalue") and it set to select element, but no changes in input element with autocomplete.
Of course, I can select this input and set value directly, but is it some other ways to do that? I try set bind to this.element like this.element.bind("change", function(){alert(1)}) but it was no effects. And I don't know why.
Edit
I found a workaround for this case. But I don't like it. I have added the following code to _create function for ui.combobox
this.element.bind("change", function() {
input.val( $(select).find("option:selected").text());
});
And when I need to change the value I can use $("#selector").val("specificvalue").trigger("change");

Is this demo what you are looking for?
The link sets the value of the jQuery UI autocomplete to Java. The focus is left on the input so that the normal keyboard events can be used to navigate the options.
Edit: How about adding another function to the combobox like this:
autocomplete : function(value) {
this.element.val(value);
this.input.val(value);
}
and calling it with the value you want to set:
$('#combobox').combobox('autocomplete', 'Java');
Updated demo
I cannot find any available existing function to do what you want, but this seems to work nicely for me. Hope it is closer to the behaviour you require.

I managed a quick and dirty way of setting the value. But, you do need to know both the value and the text of the item that you want to display on the dropdown.
var myValue = foo; // value that you want selected
var myText = bar; // text that you want to display
// You first need to set the value of the (hidden) select list
$('#myCombo').val(myValue);
// ...then you need to set the display text of the actual autocomplete box.
$('#myCombo').siblings('.ui-combobox').find('.ui-autocomplete-input').val(myText);

#andyb,
i think rewrite:
autocomplete: function (value) {
this.element.val(value);
var selected = this.element.children(":selected"),
value = selected.val() ? selected.text() : "";
this.input.val(value);
}

I really like what andyb did, but I needed it to do a little more around event handling to be able to handle triggering the a change event because "selected" doesn't handle when hitting enter or losing focus on the input (hitting tab or mouse click).
As such, using what andyb did as a base as well as the latest version of the jQuery Autocomplete script, I created the following solution: DEMO
Enter: Chooses the first item if menu is visible
Focus Lost: Partial match triggers not found message and clears entry (jQuery UI), but fully typed answer "selects" that value (not case sensative)
How Change method can be utlized:
$("#combobox").combobox({
selected: function (event, ui) {
$("#output").text("Selected Event >>> " + $("#combobox").val());
}
})
.change(function (e) {
$("#output").text("Change Event >>> " + $("#combobox").val());
});
Hopefully this helps others who need additional change event functionality to compensate for gaps that "selected" leaves open.

http://jsfiddle.net/nhJDd/
$(".document").ready(function(){
$("select option:eq(1)").val("someNewVal");
$("select option:eq(1)").text("Another Val");
$("select option:eq(1)").attr('selected', 'selected');
});
here is a working example and jquery, I am assuming you want to change the value of a select, change its text face and also have it selected at page load?
#
Attempt 2:
here is another fiddle: http://jsfiddle.net/HafLW/1/ , do you mean that you select an option, then you want to append that value to the autocomplete of a input area?
$(".document").ready(function(){
someString = "this,that";
$("input").autocomplete({source: someString.split(",")});
$("select").change(function(){
alert($(this).val()+" appended");
someString = someString+","+$(this).val();
$("input").autocomplete({source: someString.split(",")});
});
});
