I have managed to print out one array but how to do print out all arrays as this is for forum.
$(document).ready(function() {
var comments = document.getElementById("allcomments").value;
//Get Storage
var username = window.localStorage.getItem("username");
// Call Ajax for existing comments
$.ajax({
type: 'GET',
url: 'URL',
success: function(result) {
var arr = JSON.parse(result);
for(var i = 0; i < arr.length; i++) {
var obj = arr[i];
console.log(obj);
var output = document.getElementById("allcomments");
output.innerHTML = (obj.username + ' ' + obj.comment + ' ' + obj.commDate + ' ' + obj.sentiment);
}
}
});
return false;
});
Since you're using jQuery, you should consider using the append() function instead of innerHTML. There are not a lot of valid use cases for innerHTML, you should try to avoid it.

I hope you are fine!
I'm new in coding so I'm facing of something without results.
I have this type of code here in JS.
key: 'generateChart2',
value: function generateChart2() {
var self = this;
var Jahr1 = [];
var years1 = "";
for (var i = 0; i < $('#mf123_select_jahr').val().length; i++) {
if (i > 0) years1 += ","
years1 += $('#mf123_select_jahr').val()[i];
}
var postedData1 = {};
postedData1.years1 = years1;
console.log(postedData1);
$.ajax({
url: "data/json.dashboard.php?call=chart2",
data: postedData1,
dataType: 'json',
type: 'POST',
success: function (dataGraph2) {
var trHTML='';
$.each(dataGraph2, function (key, value) {
for (var i in postedData1) {
Jahr1.push(postedData1[i].years1);
}
console.log(postedData1.years1);
trHTML +=
'<tr><td >' + value.Mandant +
'</td><td >' + thousandSepNeu(value.Jahr1, 2) + " €" +
'</td><td >' + value.Growth +
'</td></tr>';
});
$('#dataGraph2').append(trHTML);
}
});
}
The value.Mandant and the value.Growth are doing well. The problem that I have is that the for loop does not work. I need to thr postedData1 to choose whenever the user choose the year to show him the results.
The output of console.log(postedData1); is:
Am I making a mistake? I know that the problem is on the for loop.
Please any advice i would appreciate it.

I have more than three TextBoxes. I want to send this data as in the code. The "indeks " value is always the last click. How do I keep the index?
click:function(e) {
var item = e.itemElement.index();
indeks = item;
}
var field= "";
onl: function () {
$.ajax({
type: "GET",
cache:true,
url: MYURL,
success: function (msg, result, status, xhr) {
var obje = jQuery.parseJSON(msg)
var i = 0;
field = " ";
$('#wrapper *').filter(':input').each(function () {
if (txtvalue != "") {
if (i)
field += " and ";
field = field + "[" + obje[indeks]+ "]" $(this ).val() + "'";
i++;
}
});
});
},
As I wasn't sure if I got your question right, I prefered to comment on your topic - but now it seems that my answer helped you, so I decided to post it as an actual answer:
1st step: declare an array outside your success handler
2nd step: push the index and the value for the element into this array
3rd step: loop through all entries of the array and build your 'select' statement
Here is your edited example:
https://jsfiddle.net/Lk2373h2/1/
var clickedIndexes = [];
click:function(e) {
var item = e.itemElement.index();
indeks = item;
}
var field= "";
onl: function () {
$.ajax({
type: "GET",
cache:true,
url: MYURL,
success: function (msg, result, status, xhr) {
var obje = jQuery.parseJSON(msg)
var i = 0;
field = " ";
$('#wrapper *').filter(':input').each(function () {
$(this).attr('id', i);
var txtvalue=$(this).val();
if (i)
clickedIndexes.push({
index: indeks,
value: $(this ).val()
});
var selectString = "";
for (var u = 0; u < clickedIndexes.length; u++) {
selectString += "[" + obje[clickedIndexes[u].index].ALAN + "]" + "=" + "'" + clickedIndexes[u].value + "'";
}
field = selectString;
i++;
});
});
},
This is my response from AJAX call
{"screen":[{"screen_name":"SCR1","screen_id":"1"},{"screen_name":"SCR2","screen_id":"2"},{"screen_name":"SCR3","screen_id":"3"},{"screen_name":"SCR4","screen_id":"4"},{"screen_name":"SCR5","screen_id":"5"},{"screen_name":"BIGSCR","screen_id":"6"}]}
success: function(response) {
var jsondata = JSON.stringify(response);
console.log(jsondata);
var html = '';
for (var i = 0; i < jsondata.screen.length; i++) {
var screenName = jsondata.screen[i].screen_name;
var screenId = jsondata.screen[i].screen_id;
html += '<option value="' + screenName + '">' + screenId + '</option>';
}
$('#SCname').append(html);
}
But I keep on getting
Uncaught TypeError: Cannot read property 'length' of undefined at for loop
Try this: It Works. As smooth as silk: (See comment for explanation)
<select id="SCname"></select>
<script>
$.ajax({
dataType: 'json',
//This JSON datatype returns a json encoded response
url:"api/test.php",
//This is the URL From where you fetch the JSON Data
success: function(response){
//Since the response array object has a single array element "screen", we make it myArray
myArray = response["screen"];
console.log(myArray);
//We get six Objects in myArray.
//Thsese are Arrays of your six screens . Now Using Loops
var html = '';
for (var i = 0; i < myArray.length; i++) {
// Each element is inside DOuble Array like: myArray[0]["screen_name"]
var screenName = myArray[i]["screen_name"];
var screenId = myArray[i]["screen_id"];
html += '<option value="' + screenName + '">' + screenId + '</option>';
}
$('#SCname').append(html);
//Check your console ouput
console.log(html);
}
});
</script>
JSON.stringify(object) returns a string. You want a JSON.parse(string) – which returns an object. Alternatively, if your response is already an object, then you don't have to parse it at all:
success: function(jsonData) {
var html = '';
for (var i = 0; i < jsonData.screen.length; i++) {
var screenName = jsonData.screen[i].screen_name;
var screenId = jsonData.screen[i].screen_id;
html += '<option value="' + screenName + '">' + screenId + '</option>';
}
$('#SCname').append(html);
You don't want to stringifybut to parse. Correct it must be:
var jsondata = JSON.parse(response);
But keep in mind that jQuery possibly is already parsing the JSON for you.
Let suppose i have a json file
and i can read this file in my script like this
$(document).ready(function () {
$.ajax({
type: "GET",
url: "Package.html",
dataType: "json",
success: function (data) {
var t = '';
for (var i = 0; i < data.yearData.length; i++) {
var mainStoryTitle = data.yearData[i].players;
for (var j = 0; j < mainStoryTitle.length; j++) {
var storyTitle = mainStoryTitle[j].name;
var topStoryContent = mainStoryTitle[j].description;
var storyImage = mainStoryTitle[j].image;
t = t + '<div class="content">';
t = t + '<article class="topcontent">';
t = t + '<header class="top" id="top1"><h2>' + storyTitle + '</h2></header>';
t = t + '<header class="bottom">';
t = t + '<h6><img src="' + storyImage + '" height=150 width=200>' + '</h6></header>';
t = t + '<content class="hide" id="content_' + j + '"><p>' + topStoryContent + '</p></content>';
t = t + '</article>';
t = t + '</div>';
}
}
$(".content").html(t);
},
error: function (e, ts, et) { alert(ts) }
})
});
and then i put this script in my html file.
So when i run this, it works properly but the problem is when i click on view source then inside it shows the path of json instead of exact data.
Hope you got the problem and please revert me asap.thanx
Instead of using alert, use console.log(ts) this will post the JSON file into your console. From there you can easily look around and see the JSON file by clicking the down arrow.
console.log(data); shows as:
> Object {Data: Array[2], ResponseMessage: "", Success: true}
console.log(JSON.stringify(data)); shows as:
{"Data":[{"ControllerID":2,"Description":"Aeon Power Monitor","DevType":1,"ID":1,"Name":"Power Monitor"},{"ControllerID":2,"Description":"Aeon Power Switch","DevType":2,"ID":2,"Name":"Switch"}],"ResponseMessage":"","Success":true}
I have values that come from a dynamically created table from it's selected rows. inside each selected row i want all the td.innerText values that belong to be sent to a C# page, but i don't know how to. I was using JSON but I dont know if i used it properly.
function selectedRows()
{
var selectedItems = $('#ScannedLabelTable').find(':checkbox:checked').parents('tr');
var serial, kanbanNumber, customer, description, quantity;
$.each(selectedItems, function (i, item) {
var td = $(this).children('td');
for (var i = 0; i < td.length; ++i)
{
serial = td[1].innerText;
kanbanNumber = td[2].innerText;
customer = td[3].innerText;
description = td[4].innerText;
quantity = td[5].innerText;
}
console.log(serial + ' ' + kanbanNumber + ' ' + customer + ' ' + description + ' ' + quantity);
});
$.ajax({
url: SEND_TO_TEXTFILE_PAGE
, data: "labelSerial=" + serial + "&kanbanNumber=" + kanbanNumber + "&customer="
+ customer + "&description=" + description + "&quantity=" + quantity
, dataType: 'json'
, success: function (status) {
if (status.Error) {
alert(status.Error);
}
}
, error: Hesto.Ajax.ErrorHandler
});
}
EDIT: sorry I must have read this too quickly. This should do it. create an array and add the data object to it in the loop.
If you just create a json object using key value pairs you can send that object to your c# controller.
function selectedRows() {
var selectedItems = $('#ScannedLabelTable').find(':checkbox:checked').parents('tr');
var serial, kanbanNumber, customer, description, quantity;
var dataArray = new Array();
$.each(selectedItems, function (i, item) {
var td = $(this).children('td');
for (var i = 0; i < td.length; ++i)
{
var InfoObject = {
serial: td[1].innerText;
kanbanNumber: td[2].innerText;
customer: td[3].innerText;
description: td[4].innerText;
quantity: td[5].innerText;
};
dataArray.push(InfoObject);
}
});
$.ajax({
url: SEND_TO_TEXTFILE_PAGE
, data: dataArray
, dataType: 'json'
, success: function (status) {
if (status.Error) {
alert(status.Error);
}
}
, error: Hesto.Ajax.ErrorHandler
});
}
