Comparing 2 arrays in jQuery - javascript

I am trying to compare 2 arrays to see if an element in one array is in another array.
But i can't seem to get it to work
//if a categories checkbox is clicked
$j('#cat-dropdown li label input').click(function(e) {
//Get all selected categories
var categories = new Array;
$j('#cat-dropdown li label input').each(function(index, element) {
if($j(this).is(':checked')){
categories.push($j(this).val());
}
}); // Categories variable now has all selected cats
$j('.products-grid li.item').each(function(index, element) {
//get all the cateroies of a product
console.log('//////////////////////'+$j(this).val())
product_cats = $j(this).attr('data-product-categories').split(",");
//Now check if the product categories is in the selected categories
var inCategoryList = false;
for (i=0;i<categories.length;i++){
if($j.inArray(categories[i],product_cats)){
console.log('test '+categories[i])
inCategoryList = true;
}
}
if(inCategoryList == false){
$j(this).hide();
}
});//end each on product-grid li.item
});//end click function
But it is not working , nothing gets hidden.. But also the inArray method seems not be working properly, is there a different way to compare 2 arrays and check if one element is in another.
The basic flow is, user selects a checkbox, the li item has a list of categories attached to it. If the checkbox matches a category then keep the item displayed if there are no matches then hide it

Doing mutual exclusive checkbox of two buttons with siblings()

I am trying to get two buttons groups with checkboxes mutually exclusive.
Here's my current result on this JS Fiddle
As you can see, there are four divs (with id="UserVsComputer", id="User1VsUser2", id="PlayableHits" and id="button-new-game").
I want the two first <div> ( UserVsComputer and User1VsUser2 ) to be mutually exclusive when we click on the checkbox of concerning <input> (i.e corresponding to the right <div>).
In JavaScript part, I did:
// Select the clicked checkbox for game type
$('input.game').on('click',function(){
setGameType();
});
function setGameType() {
// Get state of the first clicked element
var element = $('#UserVsComputer input.game');
var checkBoxState = element.prop('checked');
// Set !checkBoxState for the sibling checkbox, i.e the other
element.siblings().find('input.game').prop('checked',!checkBoxState);
updateGameType();
}
function updateGameType() {
// Set type of game
if ($('#UserVsComputer input').prop('checked'))
gameType = 'UserVsComputer';
else
gameType = 'User1VsUser2';
}
I don't want the <div id="PlayableHits" class="checkbox"> to be concerned by this mutual exclusion on two first checkboxes.
For example, below a capture showing that I can set the two first checkbox to true without making them exclusive:
What might be wrong here?
Try the following - it uses the target of the click event to ascertain which checkbox was checked:
// Select the clicked checkbox for game type
$('input.game').on('click',function(e){
setGameType(e.target);
});
function setGameType(cb) {
var container = $(cb).parent().parent();
var checkBox = $(cb);
var checkBoxState = checkBox.prop('checked');
// Set !checkBoxState for the sibling checkbox, i.e the other
container.siblings().find('input.game').prop('checked', !checkBoxState);
updateGameType();
}
function updateGameType() {
// Set type of game
if ($('#UserVsComputer input').prop('checked')) {
gameType = 'UserVsComputer';
} else {
gameType = 'User1VsUser2';
}
}
There are other bits which could use some attention (the hardcoded .parent().parent() isn't pretty but works in this case..

SAPUI5 TreeTable: User Interaction set to "true" when event fired by code

When selecting a row in my SAPUI5 tree table I have to make sure that
all existing selections are removed
check if selected row has children and if so, select the item and all its children
To do that I use a function that gets called on the rowSelectionChange-Event of my table:
onRowSelectionChange: function(oEvent) {
if (oEvent.getParameters().userInteraction)
var oTable = oEvent.getSource();
var oObject = oEvent.getParameters().rowContext.getObject();
var iIndex = oEvent.getParameters().rowIndex;
// Check if row was selected or deselected
if (oTable.isIndexSelected(iIndex)) {
// Deselect other items
oTable.clearSelection();
// Select row again
oTable.addSelectionInterval(iIndex, iIndex);
// Check if object has children
if (oObject.content) {
//Select child rows here
} else {
// Do stuff
}
} else {
// Do stuff
}
}
}
As you can see the first thing I do is to check if the selection change's origin was an explicit user interaction, because, of course, clearing the selection and then adding the selection for the child rows will call the function again.
My problem is now, that when clearSelection() calls my function, the userInteraction-parameter is again set to true, despite not being an explicit user interaction. Am I missing something here?
Thank you!

Updating based on checkbox selection

I placing some xml data in grid using extjs. Now I'm trying to build an update function,
that worked fine, however I'm trying first to extract the data to be updated, so that the user won't have to insert the whole data again.
I managed to extract the data depending on the position in the grid, but not on the selection of checkbox next to each entry in the grid.
Code:
if (btn.id == "btn_update") {
var selection = grid.getSelectionModel().getSelection();
if(selection.length == 0){
alert("Please select an item to update");
}
else if(selection.length > 1){
alert("Please only select one item to update");
}
else{
Ext.getCmp('update_name').setValue(gridStore.getAt(0).get("FirstName"));
Ext.getCmp('update_lastname').setValue(gridStore.getAt(0).get("LastName"));
Ext.getCmp('update_email').setValue(gridStore.getAt(0).get("Email"));
winupdate.show();
}
}
How can I achieve that?
Hope this will help you.
You can use checkboxSelectionModel in grid and when you click on checkbox select event will be fired and that will give you current record, index and many other.
xtype:'grid',
selModel: Ext.create('Ext.selection.CheckboxModel',{
listeners: {
select: function (el, record, index, eOpts) {
//Get current record from record variable
}
}

CodeIgniter post all select items

I have two select boxes: the first contains all avaible items and the second one contains the items I've selected from the first select box.
$items=$this->Database->getItems();
$mySelect=form_multiselect('addedMaterials', $items, '1', 'id="addedMaterials" multiple="multiple"');
To submit all the items from the second select box I've put this:
function selectAll()
{
var selObj = document.getElementById('addedMaterials');
for (var i=0; i<selObj.options.length; i++) {
selObj.options[i].selected = true;
}
}
So now, I go to the controller, where I want to get the items from the box...
$stuff = $this->input->post('addedMaterials');
My problem is that it only gets the last selected item, not all. How can I get all the items of the select box?
I've found my solution here: Post values from a multiple select
When we declare the multiple select, the attribute "name" must be name='mySelect[]'. In my case it should be:
$mySelect=form_multiselect('addedMaterials[]', $items, '1', 'id="addedPrinters" multiple="multiple"');

filtering only previously unselected <select> options qith JQuery

Previously I asked how to do this and was directed to this:
<script>
jQuery.fn.filterByText = function(textbox) {
return this.each(function() {
var select = this;
var options = [];
$(select).find('option').each(function() {
options.push({value: $(this).val(), text: $(this).text()});
});
$(select).data('options', options);
$(textbox).bind('change keyup', function() {
var options = $(select).empty().scrollTop(0).data('options');
var search = $.trim($(this).val());
var regex = new RegExp(search,"gi");
$.each(options, function(i) {
var option = options[i];
if(option.text.match(regex) !== null) {
$(select).append(
$('<option>').text(option.text).val(option.value)
);
}
});
});
});
};
</script>
(http://www.lessanvaezi.com/filter-select-list-options/)
When I use this filter on the select box it filters both the unselected AND the selected. I'd like it to ONLY filter the unselected because if a user wants to ammend the selections and filters again, the previously selected items go away - unless they meet the filter criteria.
I'm not that good at JavaScript or JQuery and can't understand how I might tell the above script to ignore options that are ":selected" but filter all else.
Here's a jfiddle if it helps: http://jsfiddle.net/UmKXy/ I'd like option one and two to remain selected and in the list when user begins to type.
Thanks for help!
The solution you had would not work with selected elements because he created an array of options at the start and then matched those options against the regex(Without regards to what is actually selected). I've used spans to hide options in the past and created an example for you to see how it works. Here is the link : http://jsfiddle.net/rD6wv/
Here is the code
$(function() {
$("#filterByText").bind('keyup',function(){
var search = $.trim($(this).val());
var regex = new RegExp(search,"gi");
$("#filez").find('option').each(function(){
if(!$(this).is(':selected')){
if($(this).val().match(regex) === null) {
$(this).wrap('<span>');
}else if($(this).parent().is('span')){
$(this).parent().replaceWith($(this));
}
}
});
});
});
You simply need to loop through all the options of the select when you type in the textbox.
You then check if it is selected, if it is you do nothing, else you check if it matches the search filter, if it does you wrap it in a span, making it invisible, else it means you need to see it, so you check if it is already wrapped in a span, and in that case you replace it with the option so you can see it again.
to selected the non selected options, use this:
$('option:not[selected]') or $('#myselect > option:not[selected]')
to remove them, use this:
$('option:not[selected]').remove();
in css, :not filters for opposite of what comes in the curved brackets.
and [] is attribute selector.
so :not[selected] means: does not have an attribute whose key is "selected"
