Try to figure out how to show content based on window.location.hash

Im using JSON and passing data through the href tag and using a click event to show specific items from a product database. My question is that I have code in the script that assigns a unique window hash to each product. It takes the product name and strips the spaces.
How can I show the correct item on the page if the hash tag matches the item when linking from an external url?
For example, when one of the items is clicked on the page the url will show something like www.website.com#CherryTomatoes.
Obviously I cant link to this from another website because the hash only exists when the click event is fired. I want to be able to automatically show the correct item when using an external link. Below is my code hope someone can help me out with this!
//display product category based on click
$("#displayall").click(function(event){
displayAll();
});
//display all products function
function displayAll() {
var categoryImage = '';
$.each(json, function (i, item) {
categoryImage += '<div class="col-lg-3 col-md-4 col-sm-6 col-xs-12">' + '' + '<img class="img-responsive img-hover productImagesCategory" src="' + item.imageURL + '">' + '<h3>' + item.itemName + '</h3>' + '' + '</div>';
});
$('#imagesCategoryProducts').hide().html(categoryImage).fadeIn('slow');
//show individual product function on click
$(".showProduct").click(function(event){
//hide all current products
$('#productCategories').hide();
//get passed data from other function
var clickedItemName = '<h1>' + $(this).data('itemname') + '</h1>';
var clickedItemUPC = $(this).data('itemupc');
var clickedItemOZ = '<h2>' + $(this).data('itemoz') + '</h2>';
var clickedItemDescription = '<p>' + $(this).data('itemdescription') + '</p>';
var clickedItemImage = '<img class="img-responsive img-rounded center-block" src="' + $(this).data('itemimage') + '">';
var clickedItemGluten = $(this).data('itemgluten');
var clickedItemBPA = $(this).data('itembpa');
var clickedItemGMO = $(this).data('itemgmo');
var clickedItemPageURL = $(this).data('itempageurl');
//check if clicked data equals correct item
$.each(json, function (i, item) {
if (item.itemName === clickedItemName) {
clickedItemName
}
if (item.itemFullUPC === clickedItemUPC) {
clickedItemUPC
}
if (item.itemPackSize === clickedItemOZ) {

clickedItemGluten
}
if (item.itemBPAFree === clickedItemBPA) {
clickedItemBPA
}
if (item.itemGMOFree === clickedItemGMO) {
clickedItemGMO
}
//assign window hash to each product
if (item.itemName === clickedItemPageURL) {
event.preventDefault();
clickedItemPageURL = clickedItemPageURL.replace(/\s/g, '');
window.location.hash = clickedItemPageURL;
}
});
//remove extra characters from UPC
var originalUPC = clickedItemUPC;
var strippedUPC = '<h2>' + originalUPC.slice(1, -1); + '</h2>';
//show individual product information
$('#productSocialShare').show();
$('#individualProduct').show();

//append product information to appropriate DIV
$('#productTitle').html(clickedItemName);
$('#productUPC').html(strippedUPC);

$('#productGlutenFree').html(clickedItemGluten);

} else {

}
//check if bpa free is true and show image
if (clickedItemBPA == "Y") {
clickedItemBPA = '<img class="img-responsive img-rounded img-margin" src="../images/misc/bpa_free_test.jpg">';

Trying to alter this JSON search so that it only searches when a submit button is pressed

New on here and a beginner at code. I have this code I am using as a Karaoke search. However, the JSON contains about 40 000 lines of info, and the search is set up to tigger on keyup, so it is very laggy sometimes. I'm hoping someone can help me alter this code so that it only searches when a submit button is pressed... Any ideas? Greatly Appreciated
$(window).load(function(){
$('#search').keyup(function(){
var searchField = $('#search').val();
var regex = new RegExp(searchField, "i");
var output = '<div class="row">';
var count = 1;
$.getJSON('data.json', function(data) {
$.each(data, function(key, val){
if ((val.name.search(regex) != -1) || (val.location.search(regex) != -1)) {
//output += '<div class="col-md-6 well">';
//output += '<div class="col-md-7">';
output += '' + val.name + ' - ';
output += '' + val.location + '';
output += '</div>';
output += '</div>';
output += '<div class="col-md-7"><img class="img-responsive" src="send.png" /></div>';
if(count%2 == 0){
output += '</div><div class="row">'
}
count++;
}
});
output += '</div>';
$('#results').html(output);
});
});
});

Assuming you placed your submit button within a form, give your form an ID.
<form id="search-form">
Change line
$('#search').keyup(function(){
to
$('#search-form').on('submit', function (e) {
e.preventDefault();

The search logic should not be implemented on the client side. It would be painful for the browser to do that kind of iteration. Transfer your search logic in the backend. : )
if you're going to fixed that on front end, please add timeout/debounce during keyup
var delay = null;
$( el ).keyup( function () {
if ( delay ) clearTimeout( delay );
var delay = setTimeout( function () {
// your search logic
} );
} );

How do I insert an object data array into a database with AJAX

I want to insert data from an array into a database table in the submit() function where the sql syntax is at. I want to insert the data then redirect to another page after successful. I don't know how to do this with ajax.
I tried to make ajax syntax but I don't know if i'm passing the data correctly for obj.name and obj.books corresponding to their own values in the array.
example:
[{"name":"book1","books":["thisBook1.1","thisBook1.2"]},{"name":"book2","books":["thisBook2.1","thisBook2.2","thisBook2.3"]}]
function submit(){
var arr = [];
for(i = 1; i <= authors; i++){
var obj = {};
obj.name = $("#author" + i).val();
obj.books = [];
$(".auth" + i).each(function(){
var data = $(this).val();
obj.books.push(data);
});
//sql = ("INSERT INTO table (author, book) VALUES ('obj.name', 'obj.books')");
//mysqli_query(sql);
arr.push(obj);
}
$("#result").html(JSON.stringify(arr));
}

Send your array to server ,stringify array before sending it to server so in server you can decode json and recover your array, and then insert received data to database
JS
function submit(){
var arr = [];
for(i = 1; i <= authors; i++){
var obj = {};
obj.name = $("#author" + i).val();
obj.books = [];
$(".auth" + i).each(function(){
var data = $(this).val();
obj.books.push(data);
});
//sql = ("INSERT INTO table (author, book) VALUES ('obj.name', 'obj.books')");
//mysqli_query(sql);
arr.push(obj);
}
sendToServer(arr)
$("#result").html(JSON.stringify(arr));
}
function sendToServer(data) {
$.ajax({
type: "POST",
data: {arr: JSON.stringify(data)},
url: "next.php",
success: function(){
}
});
}
PHP (next.php)
$data = json_decode(stripslashes($_POST['arr']));
foreach($data as $item){
echo $d;
// insert to db
}

Please Keep the following in mind
Javascript/JQuery is client side and hence cannot access the database which is on the server.
You can Send data via AJAX to next.php and then use this data to insert into your database.
To improve debugging, use the following code to ensure the correct data is being delivered in next.php
var_dump($_POST);
Your SQL statements must be executed in next.php using the data passed by $_POST (since your "type" of AJAX request is post).

Build a array of div's id using each DIV inside section

I'm trying to get the ID of each DIV inside this HTML code
<section id="choices">
<div id="talla_choice_24" style="">
...
</div>
<div id="color_choice_25" style="">
...
</div>
<div id="sport_choice_26" style="">
...
</div>
<button type="button" class="create-variation" id="create-variation" style="">Crear variaciones</button>
<section id="variations_holder" style="display: none"></section>
</section>
So I made this:
function getDivId(div) {
var inputValues = [];
$("#" + div + ' > div').each(function() {
inputValues.push($(this).val());
})
return inputValues;
}
And I call here:
$('#choices').on("click", "#create-variation", function(e) {
var parent_id = $(this).closest("section").attr("id");
var element = getDivId(parent_id);
iterateChoices("", element[0], element.slice(1), 0);
});
I need to build something like this:
var element = new Array($('#talla_choice_24 input:text'), $('#color_choice_25 input:text'), $('#sport_choice_26 input:text'));
But I get this error:
Uncaught TypeError: Object has no method 'each'
What is wrong?
UPDATE
This is the code for iterateChoices() function:
function iterateChoices(row, element, choices, counter) {
if ($.isArray(choices) && choices.length > 0) {
element.each(function(index, item) {
if (counter == 0)
row = '<input type="text" required="required" value="" name="pupc[]" /><input type="text" required="required" value="" name="pprice[]" /><input type="text" required="required" value="" name="pqty[]" />';
iterateChoices(row + '<input value="' + item.value + '">', choices[0], choices.slice(1), counter + 1);
});
} else {
html_temp = "";
$.each(element, function(index, item) {
html_temp += row + '<input value="' + item.value + '"><br>';
});
html += html_temp;
}
}
I also made some changes at this code:
function getDivId(div) {
var inputValues = [];
$("#" + div + ' > div').each(function() {
inputValues.push("#" + $(this).attr('id') + ' input:text');
});
return inputValues;
}
And now the error change to this:
Uncaught TypeError: Object #talla_choice_24 input:text has no method 'each'
UPDATE 2
I still continue change getDivId() function to build a array like this:
var element = new Array($('#talla_choice_24 input:text'), $('#color_choice_25 input:text'), $('#number_choice_23 input:text'), $('#sport_choice_23 input:text'));
But can't get it since array values are constructed as strings, see below:
function getDivId(div) {
var inputValues = [];
$("#" + div + ' > div').each(function() {
inputValues.push('$("#' + $(this).attr('id') + ' input:text")');
});
return inputValues;
}
I'm getting:
("$('#talla_choice_24 input:text')", "$('#color_choice_25 input:text')")
I think there is the problem

You are using the val method on a div element, which just returns an empty string. There is no each method on a string.
You don't need the id of each div to get the input elements inside them. This will get you the inputs in a single jQuery object:
var element = $(this).closest("section").find("> div input:text");
If you really need an array of separate jQuery objects, you can then do this:
element = element.map(function(){ return $(this); }).get();

var arr = [];
$("#create-variation").on('click', function(){
$("#choices > div").each(function(a,b){
arr.push($(this).text());
});
});

After some headaches I realized how to fix the (my) error, here is the solution to all the problems:
function getDivId(div) {
var inputValues = [];
$("#" + div + ' > div').each(function() {
inputValues.push($("#" + $(this).attr('id') + " input:text"));
});
return inputValues;
}

Assigning user input to object with variable in its index

I am trying to using the JS to take user input and modify certain object attributes based on the user's input. I am storing the object's index in the select's alt attribute in order to use that to update the correct object. I'm getting an error: element[Payment_Format_name] is undefined
The WF.php file takes data from a CSV and formats it into a mulch-dimensional object.
$(document).ready(function() {
$.getJSON('WF.php', function(data) {
var newDiv, NewDiv2, NewDiv3,InvoiceInfo, count, DeliveryMethod, PaymentFormat, Payment_Format_id, Payment_Format_name;
count = 0;
$.each(data, function(index, element) {
count = count + 1;
//document.write (count);
newDiv = $('<div/>').addClass('row').appendTo('#showdata');
newDiv3 = $('<div/>').addClass('hd').appendTo(newDiv);
$('<div class="hd_field">' + element['PmtRec']['RcvrParty']['Name']['Name1'] + '</div>').appendTo(newDiv3);
if (element['PmtRec']['PmtMethod'] === 'CHK'){
$('<div class="hd_field">Delivery Method: <select alt="Delivery_Method" " id="Delivery' + count +'" class="Delivery_Method"><option value="100" selected="selected">US Mail</option><option value="300">Foreign Mail</option><option value="J00">Certified Mail with Return Receipt</option></select><div id="Selected_Method' + count +'"></div></div>').appendTo(newDiv3);
}
else if (element['PmtRec']['PmtMethod'] === 'DAC') {
$('<div class="hd_field">Payment Format: <select alt="'+index +'" id="Payment_' + count +'" class="Payment_Format"><option value="CTX" selected="selected">Company to Company</option><option value="PPD">Company to Person</option></select><div id="Selected_Format'+count+'"></div></div>').appendTo(newDiv3);
}
$('<div class="hd_field">' + 'Total: ' + element['PmtRec']['CurAmt'] + '</div>').appendTo(newDiv3);
InvoiceInfo = element['PmtRec']['PmtDetail']['InvoiceInfo'];
$.each(InvoiceInfo, function(index, element) {
newDiv2 = $('<div/>').addClass('sub_row').appendTo(newDiv);
$('<div class="field">' + element['InvoiceNum'] + '</div>').appendTo(newDiv2);
$('<div class="field">' + element['NetCurAmt'] + '</div>').appendTo(newDiv2);
});
$('select.Payment_Format').change(function(){
Payment_Format_id = ($(this).attr('id').match(/[\d]+$/));
Payment_Format_name = ($(this).attr('alt'));
//alert(Payment_Format_name);
PaymentFormat = ($(this).val());
element[Payment_Format_name] = Payment_Format_name;
element[Payment_Format_name]['PmtRec']['PmtFormat'] = PaymentFormat;
$('#Selected_Format' + Payment_Format_id).text('Selected Format: ' + element[Payment_Format] );
});
});
console.log(data);
});
});
PHP (this is a snippet, I'm actually creating a lot more elements here)
if (($handle = fopen('upload/BEN-new.csv', "r")) === FALSE) {
die('Error opening file');
}
$headers = fgetcsv($handle, 1024, ',');
$cardCodes = array();
$payments = array();
$details = array ();
while ($row = fgetcsv($handle, 1024, ",")) {
$cardCodes[] = array_combine($headers, $row);
}
$prevCode = '';
foreach ($cardCodes as $key => $value) {
$payments[$value['CardCode']]['PmtRec']['PmtCrDr'] = 'C';
$payments[$value['CardCode']]['PmtRec']['PmtFormat'] = 'CTX';
fclose($handle);
echo json_encode($payments)

Ok, so for starters,
$('select.Payment_Format').change(function(){
Payment_Format_id = ($(this).attr('id').match(/[\d]+$/));
Payment_Format_name = ($(this).attr('alt'));
PaymentFormat = ($(this).val());
element[Payment_Format_name] = Payment_Format_name;
element[Payment_Format_name]['PmtRec']['PmtFormat'] = PaymentFormat;
$('#Selected_Format' + Payment_Format_id).text('Selected Format: ' + element[Payment_Format] );
});
});
is not what you want - this function is reassigned to the change event of the 'select.Payment_Fomat' element for each iteration of $.each(data, function(index, element). The event listener should be added outside the $.each function, inside the $.getJson call and it needs to loop over the elements object, and try to find the correct data to update.
Apologies for the uselessness earlier, it was 5am and apparently I was slightly delusional.
