Javascript:
function add_content(count)
{
var result = {};
var row = new Array();
for (i = 0; i < count; i++)
{
result['img_src'] = $("#img_" + i).attr('src');
result['desc'] = $("#desc_" + i).val();
row.push(result);
}
$.ajax({
url: "ajax-functions.php",
data: {json_data: JSON.stringify(row)},
type: 'post',
success: function (output) {
alert(output);
}
})
}
Php:
$img_desc = json_decode($_POST['json_data'],TRUE);
$count = count($img_desc);
echo 'count:'.$count;
print_r($img_desc);
I want to send json to from JS to PHP. This above code works well, but it send the last data of the for loop is set in all the objects.
How to fix it? Is this right way?
Thanks.
Push a new object on each round of the loop into to the array
for (var i = 0; i < count; i++) {
row.push({
"img_src": $("#img_" + i).attr('src'),
"desc": $("#desc_" + i).val()
});
}

Move result declaration inside for:
var row = new Array();
for (i = 0; i < count; i++)
{
var result = {};
result['img_src'] = $("#img_" + i).attr('src');
result['desc'] = $("#desc_" + i).val();
row.push(result);
}
or it can be done more elegantly:
var row = new Array();
var result;
for (i = 0; i < 10; i++)
{
result = row[ row.push({}) - 1 ];
result['img_src'] = $("#img_" + i).attr('src');
result['desc'] = $("#desc_" + i).val();
}
You can make the keys of result array also dynamic
Since you are not making it dynmamic, its getting over ridden in the next loop
EDIT:
for (i = 0; i < count; i++)
{
var result = {};
result['img_src'] = $("#img_" + i).attr('src');
result['desc'] = $("#desc_" + i).val();
row.push(result);
}

Performing an ajax call to a drinks api and I've nested a loop to pull the ingredients out and render them to the page. The nested loop consoles the ingredients correctly but when I use jquery to append the results to the page only the item in the last index is displayed. I know there are null values I was going to remove them with an if statement after I got them to show.
function displayDrinkData(drinkName) {
var queryURL = "https://thecocktaildb.com/api/json/v1/1/search.php?s=" + drinkName
$.ajax({
url: queryURL,
method: "GET"
}).then(function (response) {
console.log(response);
var results = response.drinks;
for (var i = 0; i < results.length; i++) {
console.log(results[i]);
var eachDrink = results[i];
var drinkDiv = $("<div>");
var drinkName = results[i].strDrink;
for (var k = 1; k < 16; k++) {
console.log(eachDrink['strIngredient' + k]);
var ingList = $("<ul>").text("Ingredients: " + eachDrink['strIngredient' + k])
}
var pOne = $("<p>").text("Drink name: " + drinkName);
var drinkInstructions = results[i].strInstructions;
var pTwo = $("<p>").text("Instructions: " + drinkInstructions);
var drinkImage = $("<img>");
drinkImage.attr("src", results[i].strDrinkThumb);
drinkDiv.append(pOne);
drinkDiv.append(ingList);
drinkDiv.append(pTwo);
drinkDiv.append(drinkImage);
$("#drinks-view").append(drinkDiv);
}
})
}
Because var ingList is inside loop, not appending, but creating a new one every time.
var ingList = $("<ul>");
for (var k = 1; k < 16; k++) {
console.log(eachDrink['strIngredient' + k]);
ingList.append($('<li>').text("Ingredients: " + eachDrink['strIngredient' + k]));
}
Declare variable outside loop, and append <li> for each element.
I am trying to add values in a multidimensional array in JavaScript, but it doesn't seem to work. I get "variable not defined" error in snippet but can't see any variable which is not defined.
Does anyone have any idea what's going wrong here?
Many Thanks,

var abc = "11:00, 11:10, 12:20,12:30";
var split = abc.split(",")
var limits = new Array();
var alltimes = [[],[]];
//var split = ["11:00", "11:10", "12:20","12:30"];
var x = 0;
for (var i = 0; i < split.length -1 ; i++) {
limits.push(split[i]);
// alert(split.length );
if(i%2 === 1) // If odd value
{
alert(limits);
for (var j = 0;j<2; j++)
{
// alert(limits[j]);
alltimes[x][j] = limits[j];
}
limits.length = 0;
x++;
}
// alert(split.length + 2);
//
}
alert(alltimes);
// console.log(abc)
This is my JavaScript code
$(document).ready(function(){
$('.timepicker').click(function(){
var ajaxurl = 'Ajax.php',
data = {'action': 'Hassam'};
$.post(ajaxurl, data, function (response) {
// $('#timepicker').timepicker('option', 'disableTimeRanges', [abc]);
var split = response.split(",");
var x = 0;
for (var i = 0; i < split.length -1 ; i++) {
limits.push(split[i]);
alert(split.length );
if(i%2 === 1) // If odd value
{
for (var j = 0;j<2; j++)
{
// alert(limits[j]);
alltimes[x][j] = limits[j];
}
limits.length = 0;
x++;
}
alert(split.length + 2);
//
}
alert(alltimes);
// console.log(abc)
});
There is very simple solution to achieve what you want.
var split = ["11:00", "11:10", "12:20", "12:30"];
var alltimes = [];
while (split.length) {
alltimes.push(split.splice(0, 2));
}
console.log(alltimes);
var select = [];
for (var i = 0; i < nameslots; i += 1) {
select[i] = this.value;
}
This is an extract of my code. I want to generate a list of variables (select1, select2, etc. depending on the length of nameslots in the for.
This doesn't seem to be working. How can I achieve this? If you require the full code I can post it.
EDIT: full code for this specific function.
//name and time slots
function gennametime() {
document.getElementById('slots').innerHTML = '';
var namelist = editnamebox.children, slotnameHtml = '', optionlist;
nameslots = document.getElementById('setpresentslots').value;
for (var f = 0; f < namelist.length; f += 1) {
slotnameHtml += '<option>'
+ namelist[f].children[0].value
+ '</option>';
};
var select = [];
for (var i = 0; i < nameslots; i += 1) {
var slotname = document.createElement('select'),
slottime = document.createElement('select'),
slotlist = document.createElement('li');
slotname.id = 'personname' + i;
slottime.id = 'persontime' + i;
slottime.className = 'persontime';
slotname.innerHTML = slotnameHtml;
slottime.innerHTML = '<optgroup><option value="1">00:01</option><option value="2">00:02</option><option value="3">00:03</option><option value="4">00:04</option><option value="5">00:05</option><option value="6">00:06</option><option value="7">00:07</option><option value="8">00:08</option><option value="9">00:09</option><option value="10">00:10</option><option value="15">00:15</option><option value="20">00:20</option><option value="25">00:25</option><option value="30">00:30</option><option value="35">00:35</option><option value="40">00:40</option><option value="45">00:45</option><option value="50">00:50</option><option value="55">00:55</option><option value="60">1:00</option><option value="75">1:15</option><option value="90">1:30</option><option value="105">1:45</option><option value="120">2:00</option></optgroup>';
slotlist.appendChild(slotname);
slotlist.appendChild(slottime);
document.getElementById('slots').appendChild(slotlist);
(function (slottime) {
slottime.addEventListener("change", function () {
select[i] = this.value;
});
})(slottime);
}
}
You'll have to close in the iterator as well in that IIFE
(function (slottime, j) {
slottime.addEventListener("change", function () {
select[j] = this.value;
});
})(slottime, i);
and it's only updated when the element actually change
The cool thing about JavaScript arrays is that you can add things to them after the fact.
var select = [];
for(var i = 0; i < nameSlots; i++) {
var newValue = this.value;
// Push appends the new value to the end of the array.
select.push(newValue);
}
I'm trying to parse the json grabbed from here. Basically what I do is iterate over the items, sort them, then display them. But I get an error saying data.data.children[i] is undefined.
I can't think why it's doing it though?
var json = 'http://www.reddit.com/reddits/mine/.json';
GM_xmlhttpRequest({
method: "GET",
url: json,
onload: reddits
});
function reddits(response){
var txt = response.responseText;
var data;
var suggested = document.getElementById('suggested-reddits');
if(window.JSON && JSON.parse){
data = JSON.parse(txt);
}
else{
data = eval("("+txt+")");
}
suggested.innerHTML += '<span>reddits you\'re subscribed to </span> <ul id="rsub"></ul>';
GM_addStyle('#rsub{width: 500px;}');
var reddits = new Array();
var rsub = document.getElementById('rsub');
for(i = 0; i <= data.data.children.length; i++){
var r = data.data.children[i].data.display_name;
reddits.push(r);
}
sort(reddits);
for(i = 0; i <= reddits.length; i++){
rsub.innerHTML += '<li>' + reddits[i] + '</li>';
}
}
for(i = 0; i <= data.data.children.length; i++){
var r = data.data.children[i].data.display_name;
reddits.push(r);
}
Clear problem is in the for statement. Change the i <= data.data.children.length to i < data.data.children.length. Note the inequality change.
Since arrays in Javascript are 0-indexed, the element at i = data.data.children.length does not exist.
You should probably do the same things for the reddits.length loop.
Is there a way for the JQGrid to return an array of column Data for using multiSelect as opposed to just an array of rowIds ?
At the moment I can only return the last column data that was selected.
jQuery("#buttonSelected").click(function() {
var ids = jQuery("#relatedSearchGrid").getGridParam('selarrrow');
var count = ids.length;
for (var i = 0; i < count; i++) {
var columnData = $("#relatedSearchGrid").find("tbody")[0].rows[$("#relatedSearchGrid").getGridParam('selrow') - 1].cells[1].innerHTML;
alert("In the loop and " + columnData );
}
if (count == 0) return;
var posturl = '<%= ResolveUrl("~") %>Rel******/AddSelected****/' + ids;
if (confirm("Add these " + count + " Docs?")) {
$.post(posturl,
{ ids: columnData },
function() { jQuery("#relatedSearchGrid").trigger("reloadGrid") },
"json");
}
})
Use getRowData to get the data for each row:
var rowData = $("#relatedSearchGrid").getRowData(ids[i]);
var colData = rowData.Name_Of_Your_Column;
var userListjqGrid = $('#UserListGrid'),
selRowId = userListjqGrid.jqGrid('getGridParam', 'selrow'),
userId = userListjqGrid.jqGrid('getCell', selRowId, 'UserId'),
userName = userListjqGrid.jqGrid('getCell', selRowId, 'UserName'),
subIds = $(subgridTableId).getGridParam('selarrrow'),
accessRuleIds = [];
for (var i = 0; i < subIds.length; i++) {
accessRuleIds[i] = $(subgridTableId).getRowData(subIds[i]).AccessRuleId;
}
