How to edit CSS of a JavaScript variable in JS?

I have a live search for a website and it's working just fine but I cannot seem to figure out how to highlight the search term in the result. Below is my JS code. I assume I need to edit the data-search-term variable but I am clueless about how to go about it.
I know only HTML/CSS. No JavaScript.
jQuery(document).ready(function($) {
$('.training-search-list li').each(function() {
$(this).attr('data-search-term', $(this).text().toLowerCase());
});
$('.training-search-box').on('keyup', function() {
var searchTerm = $(this).val().toLowerCase();
$('.training-search-list li').each(function() {
if ($(this).filter('[data-search-term *= ' + searchTerm + ']').length > 0 || searchTerm.length < 1) {
$(this).show();
} else {
$(this).hide();
}
});
});
});
Thanks in advance.

I made it long time ago
(function($){
$('#categoryFilter').focus().keyup(function(event){
var input = $(this);
var val = input.val();
if(val == ''){
$('#filter li').show();
$('#filter a span').removeClass('highlighted');
return true;
}
var regexp = '\\b(.*)';
for (var i in val) {
regexp += '('+val[i]+')(.*)';
}
regexp += '\\b';
$('#filter li').show();
$('#filter').find('a > span').each(function(){
var span = $(this);
var resultats = span.text().match(new RegExp(regexp,'i'));
if(resultats){
var string = '';
for (var i in resultats){
if(i > 0){
if(i%2 == 0){
string += '<span class="highlighted">'+resultats[i]+'</span>';
}else {
string += resultats[i];
}
}
}
span.empty().append(string);
}else {
span.parent().parent().hide();
}
});
});
})(jQuery);
Maybe you can try to make your own code with some part of mine

on.change() event doesn't run when manually setting value of <select>

As the title describes, I'm having a problem with a function running using the
$("element_name").on("change", some_function)
event on a select when manually setting the element's value like
$("element_name").val("")
I read something about a "chosen" and I don't understand what that has anything to do with the issue.
Anybody know why the on.change() handler isn't catching the manual value change?
EDIT: I am including additional information as the solutions suggested do not work.
trigger("change"), bind("change", and on("change") do not work.
This is the code for the recreated select that controls the value setting:
(function($) {
$.extend({
fancySelect: function(options) {
var defaults = {
autoClose: true
}
var options = $.extend(defaults, options);
$("select").hide();
$("select").each(function() {
var $select = $(this);
var $fancyselect = $('<div class="fancyselect"/>');
$select.after($fancyselect);
var $ul = $('<ul/>').appendTo($fancyselect);
$ul.hide();
var $options = $select.find("option");
var $span = $("<div/>").addClass("fancyselect-label").prependTo($fancyselect);
var $arrow = $("<div>▼</div>").addClass("fancyselect-arrow").appendTo($fancyselect);
var selected = $select.find("option[selected=selected]");
var toUse = 0;
if (selected.length == 0) {
toUse = $options.first();
} else {
toUse = selected.first();
}
$span.text(toUse.text());
$options.each(function() {
var $option = $(this);
var label = $option.text();
var value = $option.val();
if ($option.is(":selected")) {
$span.text(label);
}
var $li = $('<li value="' + value + '">' + label + '</li>').appendTo($ul).bind("click", function() {
$select.val(value);
if ($option.index() == $(this).index()) {
$options.removeAttr("selected");
$option.attr("selected", "selected");
}
$span.html(label);
if (options.autoClose) {
$ul.hide();
$fancyselect.removeClass("active");
}
$ul.find("li").removeAttr("class");
$(this).addClass("selected");
});
if ($option.is(":selected")) {
$li.addClass("selected");
}
});
if (!$select.attr("disabled")) {
var $j = 0;
$span.bind("click", function() {
if ($ul.is(":visible")) {
$ul.hide();
$fancyselect.removeClass("active");
$arrow.html("▼");
} else {
$(".fancyselect").each(function() {
$(this).find("ul").hide();
$(this).removeClass("active");
});
$ul.show();
$fancyselect.addClass("active");
$arrow.html("▼");
if ($j == 0) $ul.tinyScrollbar();
$j++;
}
});
} else {
$fancyselect.addClass("disabled");
}
});
$(document).bind("keyup keydown keypress", function(event) {
$(".fancyselect").each(function() {
var $ul = $(this).find("ul");
if ($ul.is(":visible")) {
var keycode = parseInt((event.keyCode ? event.keyCode : event.which));
if(keycode >= 48 && keycode <= 90){
$ul.find("li").each(function() {
if ($(this).text().substr(0, 1) == String.fromCharCode(event.keyCode)) {
$ul.find("li").removeAttr("class");
$(this).addClass("selected");
return;
}
});
} else if (keycode == 13) {
$ul.hide();
}
return;
}
});
});
}
});
})(jQuery);
$.fancySelect();
And this is the code for the binding:
$(".downloads-series-sort select").trigger("change", load_downloads);

if statement echo out different links for different codes

I am using this code
HTML:
<div id="message">some message</div>
<input type="text" id="myInput" />​
jQuery:
$(function() {
$("#message").hide();
$("#fail").hide();
var prefix = ['HX', 'HD', 'BD', 'LS']
$('#myInput').keyup(function(e) {
var value = $(this).val();
var firstTwo = value.substr(0,2);
var firstTwoUpper = firstTwo.toUpperCase();
if(firstTwo != firstTwoUpper) {
$(this).val( value.replace(/^\w\w/, firstTwoUpper) );
}
if(value.length > 1) {
if($.inArray(firstTwoUpper, prefix) >= 0) {
$("#fail").hide();
$("#message:hidden").fadeIn();
} else {
$("#message").hide();
$("#fail:hidden").fadeIn();
}
} else {
$("#message").hide();
$("#fail").hide();
}
});
});
​
To be a post code check. I got the above code from here: Jquery check array perform function and it works just fine but I want to display a message containing a link which all differ from one another. For example I want code 'HX' to link to facebook and I want 'BD' to link to the BBC. How would I write the if statement correctly? I have tried various ways but I am not achieving what I need.
Could someone give me a little guideance please?
Thanks,
Ben.

This fiddle does what you might be looking for
<div id="message">Some link</div>
<div id="fail">Invalid postcode</div>
<input type="text" id="myInput" />
$(function () {
$("#message").hide();
$("#fail").hide();
var prefix = ['HX', 'HD', 'BD', 'LS'];
var links = ['http://www.facebook.com','http://www.example.com','http://www.bbc.com','#'];
$('#myInput').keyup(function (e) {
var value = $(this).val();
var firstTwo = value.substr(0, 2);
var firstTwoUpper = firstTwo.toUpperCase();
if (firstTwo != firstTwoUpper) {
$(this).val(value.replace(/^\w\w/, firstTwoUpper));
}
if (value.length > 1) {
var index = $.inArray(firstTwoUpper, prefix);
if (index >= 0) {
$("#fail").hide();
$("#message").fadeIn();
$("#message a").attr("href",links[index]).html(links[index])
} else {
$("#message").hide();
$("#fail:hidden").fadeIn();

I changed prefix from an array of strings to an array of objects.
You're going to see an issue if users type really fast because of the speed of fadeIn().
$(function() {
$("#message").hide();
$("#fail").hide();
var prefix = [{code:'HX',link:'www.facebook.com'}, {code:'BD',link:'www.bbc.com'}];
$('#myInput').keyup(function(e) {
var value = $(this).val();
var firstTwo = value.substr(0,2);
var firstTwoUpper = firstTwo.toUpperCase();
if(firstTwo != firstTwoUpper) {
$(this).val( value.replace(/^\w\w/, firstTwoUpper) );
}
if(value.length > 1) {
for(var obj in prefix){
console.log(firstTwoUpper, prefix[obj].code, firstTwoUpper == prefix[obj].code);
if(firstTwoUpper === prefix[obj].code){
$("#fail").hide();
var link = ''+prefix[obj].link+'';
$("#message").append(link);
$("#message:hidden").fadeIn();
break;
}else {
$("#message").hide();
$("#fail:hidden").fadeIn();
}
};
} else {
$("#message").empty();
$("#message").hide();
$("#fail").hide();
}
});
});

$('#myInput').keyup(function (e) {
var value = $(this).val();
var firstTwo = value.substr(0, 2);
var firstTwoUpper = firstTwo.toUpperCase();
if (firstTwo != firstTwoUpper) {
$(this).val(value.replace(/^\w\w/, firstTwoUpper));
}
if (value.length > 1) {
if ($.inArray(firstTwoUpper, prefix) >= 0) {
if (firstTwoUpper == "HX") {
$("#message").empty();
$("#message").html('<p>some message</p>Google');
} else if (firstTwoUpper == "HD") {
$("#message").empty();
$("#message").html('<p>other message</p><a `enter code here`href="http://www.stackoverflow.com">Stack OverFlow</a>');
}
$("#fail").hide();
$("#message:hidden").fadeIn();
} else {
$("#message").hide();
$("#fail:hidden").fadeIn();
}
} else {
$("#message").hide();
$("#fail").hide();

jQuery: Compact way to fetch values of all input fields?

I have a form with five input fields and a register button ('.register').
I want to enable the register button ONLY IF all fields have at least one character.
Here comes my code:
$(document).ready(function() {
// when page loads
$('.register').addClass('a_unclickable');
// Input validation
// Are all fields filled out?
$('input').on('keyup', function() {
var un_value = $('#username_operators').val();
var fn_value = $('#first_name_operators').val();
var ln_value = $('#last_name_operators').val();
var e_value = $('#email_operators').val();
var pw_value = $('#password_operators').val();
var pw_r_value = $('#password_repeat_operators').val();
if ((un_value.length > 0) && (fn_value.length > 0) && (ln_value.length > 0) && (e_value.length > 0) && (e_value.indexOf('#') !== -1) && (pw_value.length > 0) && (pw_r_value.length > 0)) {
$('.register').removeClass('a_unclickable');
} else {
$('.register').addClass('a_unclickable');
}
})
});
I have the feeling that there is a much easier way to achieve the same result. Does anyone of you have a compact suggestion?

That's quiet compact:
$(document).ready(function() {
// when page loads
$('.register').addClass('a_unclickable');
// Input validation
// Are all fields filled out?
$('input').on('keyup', function() {
$('.register').removeClass('a_unclickable');
$('input').each(function() {
if ($(this).val() === '') {
$('.register').addClass('a_unclickable');
}
});
})
});

A couple of things come to mind. First:
$('input').on('keyup', function() {
var valid = true;
$('#username_operators, #first_name_operators, #last_name_operators, #email_operators, #password_operators, #password_repeat_operators').each(function() {
if (/^\s*$/.test(this.value)) {
valid = false;
}
});
if (valid) {
$('.register').removeClass('a_unclickable');
}
else {
$('.register').addClass('a_unclickable');
}
});
You can combine all the Ids into one CSS selector. Really the cleanest way is to add a class name to each required input, then utilize event.target.form to find all required fields inside the form.
$('input').on('keyup', function(event) {
var valid = true;
$(event.target.form).find(".required").each(function() {
if (/^\s*$/.test(this.value)) {
valid = false;
}
});
if (valid) {
$('.register').removeClass('a_unclickable');
}
else {
$('.register').addClass('a_unclickable');
}
});

Wrap the inputs in a <div class="verifyLength" ></div>
Add the a_unclickable class to the register field by default.
Then jquery:
$('input').on('keyup', function() {
var emptyField = false;
$(".verfyLength").find("input").each(function()
{
if((this).val().length() <=0)
emptyField = true;
});
if(emptyField)
$('.register').addClass('a_unclickable');
else
$('.register').removeClass('a_unclickable');
});

Here you go JSFiddle
var arr = [un_value, fn_value, ln_value, e_value, pw_value, pw_r_value];
$.each(arr,function(i,item){ if(item.length > 0){
$('.register').removeClass('a_unclickable');
} else {
$('.register').addClass('a_unclickable');
}})
if you are able to read all the values with selector you could pass them
like:
$.each($('input'),function(i,item){ if($(item).val().length > 0){
$('.register').removeClass('a_unclickable');
} else {
$('.register').addClass('a_unclickable');
}})

Have a look at this jsfiddle:
var i = 0, count = 0;
$.each($( ":input" ), function( index, value ) {
if(value.value.length > 0) {
count++;
}
});
if(count === 6) {
console.log(true);
} else {
console.log(false)
}

selections validation by value with jquery

I have 5 select fields with id's id1, id2,.. id5
and i need check if values (selected) not equal then highlight green and if equal then highlight red
but is look crazy validate each field 5 times? is posible use special functions ir validate easy than with:
if
if
if
if
I dont need a code just idea.

You can loop through each select to compare the values
$("select").change(function () {
flag = false;
var value = $(this).val();
$("select").each(function () {
if ($(this).val() != value)
flag = true;
});
if (flag)
$("select").css("color", "red");
else
$("select").css("color", "green");
});
Demo
Edit
$("select").change(function () {
var flag = true;
$("select").each(function () {
var outer = this;
$("select").not(outer).each(function () {
if ($(outer).val() == $(this).val()) {
flag = false;
return false;
}
});
});
if (flag)
$("select").css("color", "green");
else
$("select").css("color", "red");
});
Updated Fiddle
New update
I've simplified the code like this. YOu dont have to use nested loop if you do like this
$("select").change(function () {
var flag = true;
$("select").each(function () {
if ($("select").find("option:selected[value=" + this.value + "]").length > 1) {
flag = false;
return false;
}
});
if (flag)
$("select").css("color", "green");
else
$("select").css("color", "red");
});
Updated Fiddle

Try this one..
$("select").change(function(){
var selected = [];
var valiSel = [];
$('select > option:selected').each(function() {
if($(this).val() != 0){
selected.push( $(this).val() );
}
valiSel.push( $(this).val() );
});
var unique = unique12(selected);
var uniqueLength = unique.length;
var valiSelUnique = unique12(valiSel);
var selectedLength = selected.length;
if( unique.length != selected.length ){
alert( 'Two Selected value cannot be same' );
return false;
}
//return true;
});
function unique12(sel) {
var r = new Array();
o:for(var i = 0, n = sel.length; i < n; i++)
{
for(var x = 0, y = r.length; x < y; x++)
{
if(r[x]==sel[i])
{
//alert('this is a DUPE!');
continue o;
}
}
r[r.length] = sel[i];
}
return r;
}
