I have the JS code below which filters based on checkboxes being checked or not (I don't think you need to see all the HTML because my question is rather simple/general, I think). All this code works fine, but I added a new function at the bottom (I noted it in the code) that simply has an uncheck all button for one of the sets of checkboxes (because there are like 30 checkboxes and I don't want the user to have to uncheck them all manually).
Anyway, the new script works properly too, except that the overall unrelated script that compares all checkboxes needs to run each time the new Uncheck All/Check All button is clicked.
Is there a simple way to make sure all the other JS runs when this new script is run?
I could be wrong, but I think I just need to somehow trigger this function inside the NEW FUNCTION:
$checkboxes.on('change', function() {
but am not sure how to do that.
ALL JS:
<script>
$(window).load(function(){
Array.prototype.indexOfAny = function(array) {
return this.findIndex(function(v) {
return array.indexOf(v) != -1;
});
}
Array.prototype.containsAny = function(array) {
return this.indexOfAny(array) != -1;
}
function getAllChecked() {
// build a multidimensional array of checked values, organized by type
var values = [];
var $checked = $checkboxes.filter(':checked');
$checked.each(function() {
var $check = $(this);
var type = $check.data('type');
var value = $check.data('value');
if (typeof values[type] !== "object") {
values[type] = [];
}
values[type].push(value);
});
return values;
}
function evaluateReseller($reseller, checkedValues) {
// Evaluate a selected reseller against checked values.
// Determine whether at least one of the reseller's attributes for
// each type is found in the checked values.
var data = $reseller.data();
var found = false;
$.each(data, function(prop, values) {
values = values.split(',').map(function(value) {
return value.trim();
});
found = prop in checkedValues && values.containsAny(checkedValues[prop]);
if (!found) {
return false;
}
});
return found;
}
var $checkboxes = $('[type="checkbox"]');
var $resellers = $('.Row');
$checkboxes.on('change', function() {
// get all checked values.
var checkedValues = getAllChecked();
// compare each resellers attributes to the checked values.
$resellers.each(function(k, reseller) {
var $reseller = $(reseller);
var found = evaluateReseller($reseller, checkedValues);
// if at least one value of each type is checked, show this reseller.
// otherwise, hide it.
if (found) {
$reseller.show();
} else {
$reseller.hide();
}
});
});
//NEW FUNCTION for "UNCHECK ALL" Button
$(function() {
$(document).on('click', '#checkAll', function() {
if ($(this).val() == 'Check All') {
$('input.country').prop('checked', true);
$(this).val('Uncheck All');
} else {
$('input.country').prop('checked', false);
$(this).val('Check All');
}
});
});
});
New button HTML for the new UNCHECK portion:
<input id="checkAll" type="button" value="Uncheck All">
I kept researching and discovered the trigger() function to handle this.
http://api.jquery.com/trigger/
On a checkbox change event, one of a javascript bind the toggle action.
Later on(in a different script) I want to change toggle action based on a condition.
Ex.
script 1:
$(document).ready(function () {
var shipFields = $('.address1 input');
$("input[name = 'same_as_bill']").on("change", function (evt) {
toggleFields(shipFields, !$(this).is(":checked"));
});
function toggleFields(fields, show) {
var inputFields = $("li", fields).not(".sameas, .triggerWrap");
inputFields.toggle(show);
}
}
Script 2:
$(document).ready(function () {
$('li.sameas input').click(function (sender) {
var target = $(sender.target);
var selectedCountryValue = $('li.country select', target.closest('fieldset')).val();
// determine data method based on country selected
if (selectedCountryValue === "xxx") {
ShowAddress(true, target);
} else {
ShowAddress(false, target);
}
});
function kleberShowAddress(show, target) {
if (show) {
$('li.address).hide();
} else {
$('li.address).show();
}
}
});
Issue I have here is, my site load the script 1 first and then the script 2. So by the time script 2 performs the action, toggle action is queued and will trigger that after the changes from script 2, that will revert the changes which I want.
Is there a way to remove the action in the queue? or stop happening first request. I do not want to use .unbind() which will stop triggering script 1 function. I just want to stop the action when ever it meets the condition in script 2.
Please note: above functions are trimmed to show less codes.
add var isActive = true; and use it to check in first script.
In script 2, you can call isActive = false any time you want to disable the first script's function or isActive = true for re-enable them.
Your code will look like:
//script1
var isActive = true;
$(document).ready(function() {
var shipFields = $('.address1 input');
$("input[name = 'same_as_bill']").on("change", function(evt) {
if (isActive) {
toggleFields(shipFields, !$(this).is(":checked"));
}
});
function toggleFields(fields, show) {
if (isActive) {
var inputFields = $("li", fields).not(".sameas, .triggerWrap");
inputFields.toggle(show);
}
}
});
//script2
$(document).ready(function() {
isActive = false;
$('li.sameas input').click(function(sender) {
var target = $(sender.target);
var selectedCountryValue = $('li.country select', target.closest('fieldset')).val();
// determine data method based on country selected
if (selectedCountryValue === "xxx") {
ShowAddress(true, target);
} else {
ShowAddress(false, target);
}
});
function kleberShowAddress(show, target) {
if (show) {
$('li.address').hide();
} else {
$('li.address').show();
}
}
});
I am trying to do required validation in a asp.net page.
I have multiple controls that will be hidden and displayed.
Controls like checkboxlist,dropdownlist,multiselectedlistbox.
I am using a css class called required attaching to all these controls to check the validation.
I am trying to check if each control has value or not but my code is checking each options with in each controls.
I am really not finding a way not a jquery expert just a novice...
Here is my code any ideas anyone please....
$("input[type='submit']").click(function () {
if ($(this).val() != 'Back') {
var names = [];
var info=" ";
$('.required input').each(function () {
var control = $(this);
if (control.is(':enabled')) {
names[$(this).attr('name')] = true;
}
});
$('.required option').each(function () {
var control = $(this);
if (control.is(':enabled')) {
names[$(this).attr('name')] = true;
}
});
for (name in names) {
var radio_buttons = $("input[name='" + name + "']");
if ((radio_buttons.filter(':checked').length == 0) ||(radio_buttons.filter(':selected').length == 0)) {
info += radio_buttons.closest("table").find('label').html()+"</br>";
}
}
if (info != " ") {
$("#validation_dialog p").html(info);
$("#validation_dialog").dialog({
title: "Validation Error!",
modal: true,
resizable: false,
buttons: {
Close: function () {
$(this).dialog('close');
}
}
});
return false;
}
}
});
here is a fiddle for it...

I think what you want is:
$(".required input[type='radio']:checked").each(function(){
});
instead of :
$(".required option").each(function(){ ... });
Hi I made some changes to your fiddle basically I checked for the inputs inside each column like this and then I added them to your names array.
Using
$('table.required:eq(0) input:checked')
I you can got all the inputs that are checked on the first column if the lenght of the array returned is 0 then no input is checked, i't the same procedure for the other ones.
An yes those input names are weird.

I am using jQuery to validate some fields in a form, and seem to be having an issue with one field in particular (#inputTel).
If an incorrect format is entered, an error message pops up underneath, which is fine, but the problem is once the correct format is entered the message does not disappear.
Here's a jsFiddle with the complete demo.
This is the section in question:
//Tel Validate
function is_valid_tel() {
$this = $("#inputTel");
var pattern = new RegExp("^\d{11}$");
if (pattern.test($this.val())) { // valid
if ($this.closest(".control-group").hasClass("error")) $this.closest(".control-group").removeClass("error");
$this.siblings(".help-inline").css("display", "none");
return true;
} else { // error
if (!$this.closest(".control-group").hasClass("error")) $this.closest(".control-group").addClass("error");
$this.siblings(".help-inline").css("display", "block");
return false;
}
}
Every other field works as expected except this one. My jQuery skills are limited so I'm unsure of how to solve this.
Problem in your code:
Replace var pattern = new RegExp("^\d{11}$"); with var pattern = new RegExp(/^\d{11}$/);
Updated code
//Tel Validate
function is_valid_tel() {
$this = $("#inputTel");
var pattern = new RegExp(/^\d{11}$/);// Update this line
if (pattern.test($this.val())) { // valid
if ($this.closest(".control-group").hasClass("error")) $this.closest(".control-group").removeClass("error");
$this.siblings(".help-inline").css("display", "none");
return true;
} else { // error
if (!$this.closest(".control-group").hasClass("error")) $this.closest(".control-group").addClass("error");
$this.siblings(".help-inline").css("display", "block");
return false;
}
}
Check the fiddle http://jsfiddle.net/rfg8H/
You could also use something like below, less cubersome:
$(function() {
function validateTheForm() {
var ok = true;
$(".input-medium").each(function() {
if($(this).val() == "") //use regex actually here
{
$(this).next().css("display","inline");
ok = false;
}
else {
$(this).next().css("display","none");
}
});
return ok;
}
$(".btn").click(function() {
$("form").submit(validateTheForm());
$("form").submit();
});
});
Okay,
Another novice type question.
I have this array within the head section on my website and want to use it inline JavaScript:
var MyVariable = {"chkboxid":"chkbox"}
chkboxid is a id of a checkbox input.
Now, while validating the checkbox input on form submit, neither this works
$("form#myform").submit(function () {
if ($(MyVariable.chkboxid).is(":checked")) {
} else {
alert(CommentsPlus.nochkboxmsg);
return false;
}
Nor This (check the double quote at the variable)
$("form#myform").submit(function () {
if ($("MyVariable.chkboxid").is(":checked")) {
} else {
alert(CommentsPlus.nochkboxmsg);
return false;
}
However, if I hardcode the checkbox input id, it works. I mean "input#chkbox" in place of MyVariable.chkboxid.
$("form#myform").submit(function () {
if ($("input#chkbox").is(":checked")) {
} else {
alert(CommentsPlus.nochkboxmsg);
return false;
}
How can I use that variable instead of hard coding the input id?
You are missing the "#" before the ID:
$("form#myform").submit(function () {
var element = $("#" + MyVariable.chkboxid)
if (element.is(":checked")) {
} else {
alert(CommentsPlus.nochkboxmsg);
return false;
}
}
Note however that chkboxid is the key, the actual ID of the checkbox should be the value:
var MyVariable = {"chkboxid": "real_id_here"}
please check below code.hope it will work
$("form#myform").submit(function () {
if ($("#chkboxid").is("checked")) {alert("checked");
} else {
alert("not checked");
}
});
