Using javascript like a function with button

I want to use this code as a function () to be run only when I click a button and not automatically when dropdown is changed. When click on <button onclick="CalendarFilter">Cercar</button> it runs the function. I tried putting the code into this but not working.
function myFunction()
{
CODE HERE
}
$(document).ready(function () {
$('.filter').change(function () {
var values = [];
$('.filter').each(function () {
var colIdx = $(this).data('col');
$(this).find('option:selected').each(function () {
if ($(this).val() != "") values.push( {
text: $(this).text(),
colId : colIdx
});
});
});
filter('table > tbody > tr', values);
});
function filter(selector, values) {console.log(values);
$(selector).each(function () {
var sel = $(this);
var tokens = sel.text().trim().split('\n');
var toknesObj = [], i;
for(i=0;i<tokens.length;i++){
toknesObj[i] = {
text:tokens[i].trim(),
found:false
};
}
var show = false;
//console.log(toknesObj);
$.each(values, function (i, val) {
if (toknesObj[val.colId].text.search(new RegExp("\\b"+val.text+"\\b")) >= 0) {
toknesObj[val.colId].found = true;
}
});
console.log(toknesObj);
var count = 0;
$.each(toknesObj, function (i, val) {
if (val.found){
count+=1;
}
});
show = (count === values.length);
show ? sel.show() : sel.hide();
});
}
});
When click on Cercar it runs the CalendarFilter
Thanks.

I need a way to run this like this:
function myFunction()
{
$(document).ready(function () {
$('.filter').change(function () {
var values = [];
$('.filter').each(function () {
var colIdx = $(this).data('col');
$(this).find('option:selected').each(function () {
if ($(this).val() != "") values.push( {
text: $(this).text(),
colId : colIdx
});
});
});
filter('table > tbody > tr', values);
});
function filter(selector, values) {console.log(values);
$(selector).each(function () {
var sel = $(this);
var tokens = sel.text().trim().split('\n');
var toknesObj = [], i;
for(i=0;i<tokens.length;i++){
toknesObj[i] = {
text:tokens[i].trim(),
found:false
};
}
var show = false;
//console.log(toknesObj);
$.each(values, function (i, val) {
if (toknesObj[val.colId].text.search(new RegExp("\\b"+val.text+"\\b")) >= 0) {
toknesObj[val.colId].found = true;
}
});
console.log(toknesObj);
var count = 0;
$.each(toknesObj, function (i, val) {
if (val.found){
count+=1;
}
});
show = (count === values.length);
show ? sel.show() : sel.hide();
});
}
});
}
To call that function using a button.
<button onclick="myFunction()">Cercar</button>
The problem is that this way is not working.
Thanks.

Hi guys, I have some star rating jquery code, right now I can use one set of stars and retrieve the values but, I want to be able to get values for three different sets of stars. i'm only getting values for #1_star_input and it does the same for the other two.

JavaScript - Set function to return all items based on 1 or 2 selected tags (NO jQUERY)

I have some JavaScrip that is meant to check if there are any media tags selected or industry tags selected--this is so the portfolio items can be sorted and displayed accordingly in the browser.
What I have almost works 100%, but I can't figure out how to make it so that if only a media tag is selected or if only an industry tag is selected, the portfolio items should still be sorted accordingly. Currently, you have to select a media tag AND an industry tag, but I'd like users to be able to search using just a media tag OR just an industry tag.
Here is what I want to accomplish: If only a media tag is selected, then get all portfolio pieces that are associated with that media tag. If only an industry tag is selected, get all portfolio items that are associated with that industry tag. If a media tag AND industry tag are selected at the same time, get all portfolio items that are associated with BOTH.
Vanilla JS isn't my strong point so forgive me if this is a dumb question, but this has had me stumped for hours now.
No jQuery answers, please, as this whole page's functionality is built using JavaScript.
Here is the function:
var update = function () {
closeDrawer();
// update ui to reflect tag changes
// get our list of items to display
var itemsToDisplay = [];
var currentMediaTag = controlsContainer.querySelector('.media.selected');
var currentIndustryTag = controlsContainer.querySelector('.industry.selected');
if (currentMediaTag != "" && currentMediaTag != null) {
selectedMediaFilter = currentMediaTag.innerHTML;
}
if (currentIndustryTag != "" && currentIndustryTag != null) {
selectedIndustryFilter = currentIndustryTag.innerHTML;
}
if (selectedMediaFilter == "" && selectedIndustryFilter == "") {
itemsToDisplay = portfolioItems.filter(function (item) {
return item.preferred;
});
} else {
itemsToDisplay = portfolioItems.filter(function (item) {
var mediaTags = item.media_tags,
industryTags = item.industry_tags;
if(industryTags.indexOf(selectedIndustryFilter) < 0){
return false;
}
else if(mediaTags.indexOf(selectedMediaFilter) < 0){
return false;
}
else{
return true;
}
});
}
renderItems(itemsToDisplay);
}
Not entirely sure it's necessary but just in case, here is the complete JS file that handles the portfolio page:

That part is giving you headaches. Whenever no industry tag or media tag is selected this will exit the function.
Change to:
if(industryTags.indexOf(selectedIndustryFilter) < 0 && mediaTags.indexOf(selectedMediaFilter) < 0){
return false;
}
Now it will test if at least one tag is selected. If so then render items.

I made a change just to experiment with an idea, and this setup works:
if((selectedIndustryFilter !="" && industryTags.indexOf(selectedIndustryFilter) < 0) || (selectedMediaFilter !="" && mediaTags.indexOf(selectedMediaFilter) < 0)){
return false;
}
return true;
Not sure if it's the best solution ever but it seems to work and I'm not going to complain.

I have same issue and my solution is exclude bootstrap.js on my custom theme.
also you can alter bootstrap.js
Maybe The problem is because of two version ov jquery load on your page, inspect your javascript and if there is two version of jquery, let one exist and remove another.

In my case, there are 2 jquery files (core, theme). I removed it from theme. it works perfectly fine.

Javascript hover with querySelectorAll

How do such a thing to work:
function getElements(attrib) {
return document.querySelectorAll('[' + attrib + ']');
}
$(window).load(function () {
$(".b1").hover(function () {
$(this).className = 'x';
var elements = getElements('code');
for (var i = 0; i < elements.length; i++) {
if (elements[i] == 'wow') {
elements[i].className = 'blue';
} else {
elements[i].className = 'red';
}
}
}, function () {
$(this).className = 'y';
});
});
http://jsfiddle.net/rc6Pq/10/
I would like hover to "BUTTON HOVER" and then show this elements with atributes "code" in different colors for "wow" and "lol".
Regards and thanks in advance!

What about this version:
function getElements(attrib) {
return $('[' + attrib + ']');
}
$(window).load(function () {
$(".b1").hover(function () {
$(this).className = 'x';
var elements = getElements('code');
getElements('code').addClass('red').filter('[code="wow"]')
.removeClass('red').addClass('blue');
}, function () {
$(this).className = 'y';
});
});
http://jsfiddle.net/rc6Pq/11/
or even better:
var elements = getElements('code'),
wow = getElements('code').filter('[code="wow"]').addClass('blue');
elements.not(wow).addClass('red');
http://jsfiddle.net/rc6Pq/12/
