Having a few issues trying to get this function output to an ajax table (working fine) and an input box called connectsList1.
i cannot get it to spit out into the input box without error, the error is
Uncaught TypeError: Cannot set property 'innerHTML' of null
and
connectsList1 is not defined
function getConnections(txt1) {
func_getConnections(
function (response) {
var sortorder = txt1;
var arr = response;
var i;
var Count;
var mCount;
var oCount;
var out =
"<thead>"
for (i = 0; i < arr.length; i++) {
out +=
"<tr>" +
"<tbody>" +
"<tr class=\"" + ReturnValuesAsColor(arr[i].o, arr[i].m, arr[i].server_proc) + "\">" +
"<td>" + arr[i].id + "</td>" +
//"<td>" + arr[i].user_id + "</td>" +
"<td>" + arr[i].user_name + "</td>" +
"<td>" + arr[i].workstation_name + "</td>" +
"<td>" + (!!arr[i].ip_address ? arr[i].ip_address : '') + "</td>" +
"<td>" + formatDateTime(arr[i].connect_date, 'datelongtime') + "</td>" +

"<td>" + (!!arr[i].app_ver ? arr[i].app_ver : '') + "</td>" +
"<td>" + (!!arr[i].app_date ? formatDateTime(arr[i].app_date, 'shortdate') : '') + "</td>" +
"<td>" + Messages_flag(arr[i].get_messages_flag) + "</td>" +
"<td>" + FixNumbers(arr[i].message_type_flags) + "</td>" +
//"<td>" + arr[i].o + "</td>" +
//"<td>" + arr[i].m + "</td>" +
"<td>" + arr[i].group_name + "</td>" +
//"<td>" + arr[i].server_proc + "</td>" +
"<td> <button id=\"DelImg1\" type=\"button\" name=\"btnsubmit\" class=\"ui-button ui-widget ui-state-default ui-corner-all\" onclick=\"clearText('<%= result.ClientID%>'); CopyId(" + arr[i].id + "); return Message(" + arr[i].id + ")\" >Delete</button> </td>" +
"</tr>" +
"</tbody>";
mCount = 0
if (arr[i].m != 0) {
mCount += 1;
} else if (arr[i].o != 0) {
oCount += +1;
} else if (arr[i].o == 0 & arr[i].m == 0) {
Count += 1;
}
document.getElementById("dtBody1").innerHTML = out;
document.getElementById('ConnectsList1').innerHTML = out;
ConnectsList1 = " Connection list: " & Count + oCount + mCount & " connection(s) Main Application : " & Count & " Online : " & oCount & " Mobile : " & mCount;
}})};
Any help or advice welcome, still learning ajax myself
document.getElementById("dtBody1") can not find any tag with id dtBody1. Make sure your HTML has an element with that ID.
And remember to declare the ConnectsList1 variable to avoid the second error.

I am using json.data.schedules[0].liveVideoList , json.data.schedules[1].liveVideoList
, json.data.schedules[2].liveVideoList and so on
Please tell me how can I use loop here to get all path
script.js code
var b = location.search.split('b=')[1];
$.get(
"index2.php",
{ "b": b },
function (data) {
var json = JSON.parse(data);
$.each(json.data.schedules[0].liveVideoList, function (i, v) {
var str = v.thumbnailUrl.split("vi/").pop();
var datee = v.publishDate.slice(0, 9);
var timee = v.publishDate.slice(9, 20);
var tblRows = "<tr>" + "<td>" + v.title + "</td>" + "<td>" + 0 + ' ₹' + "</td>" + "<td>" + datee + "</td>" + "<td>" + timee + "</td>" + "<td><a target='_blank' href='" + str + "'>" + "WATCH/DOWNLOAD" + "</a></td>" + "</tr>";
$(tblRows).appendTo("#userdata");
});
}
);
You can use two loops like this.
$.each(json.data.schedules, function (index, schedule) {
$.each(schedule.liveVideoList, function (i, v) {
var str = v.thumbnailUrl.split("vi/").pop();
var datee = v.publishDate.slice(0, 9);
var timee = v.publishDate.slice(9, 20);
var tblRows = "<tr>" + "<td>" + v.title + "</td>" + "<td>" + 0 + ' ₹' + "</td>" + "<td>" + datee + "</td>" + "<td>" + timee + "</td>" + "<td><a target='_blank' href='" + str + "'>" + "WATCH/DOWNLOAD" + "</a></td>" + "</tr>";
$(tblRows).appendTo("#userdata");
});
});
A for..of loop
for (let schedule of json.data.schedules) {
//Do something with schedule
}
A for..in loop
for (let scheduleIndex in json.data.schedules) {
//Do something with json.data.schedules[scheduleIndex]
}
A for loop
for (let index = 0; index < json.data.schedules.length; index++) {
//Do something with json.data.schedules[index]
}
A while loop
var index = 0;
while (index < json.data.schedules.length) {
//Do something with json.data.schedules[index]
index++;
}
I Know why I'm getting undefined but i have no idea how to solve.
Tried to put null, but it is taking in as a text
var text ='{"employees":[' +
'{"name":"Tony","mobile":"99221111","email":"tony#json.com"},' +
'{"name":"Linda","mobile":"98981111","email":"linda#json.com"},' +
'{"name":"Patrick","mobile":"90902222","email":"patrick#json.com"},' +
'{"name":"Isabella","mobile":"99552222"}]}';
obj = JSON.parse(text);
for(var i in obj.employees)
{
document.getElementById("table").innerHTML += "<tr><td>" + obj.employees[i].name + "</td>" + "<td>" + obj.employees[i].mobile + "</td>"
+ "<td>" + obj.employees[i].email + "</td></tr>";
}
Hi, for Isabella there is no email, hence I'm getting undefined when I loop through to print out their details on html, however what I'm expecting is for the email portion to be empty in the table for Isabella. Is there a way to solve it?
You can use logical OR (|| in JavaScript), which will use the second value (empty string in this case) if the first value (email) is undefined:
var text = '{"employees":[' +
'{"name":"Tony","mobile":"99221111","email":"tony#json.com"},' +
'{"name":"Linda","mobile":"98981111","email":"linda#json.com"},' +
'{"name":"Patrick","mobile":"90902222","email":"patrick#json.com"},' +
'{"name":"Isabella","mobile":"99552222"}]}';
obj = JSON.parse(text);
for (var i in obj.employees) {
document.getElementById("table").innerHTML += "<tr><td>" + obj.employees[i].name + "</td>" + "<td>" + obj.employees[i].mobile + "</td>" +
"<td>" + (obj.employees[i].email || '') + "</td></tr>";
}
<table id="table"></table>
I'm making a table with a for each loop.
In every row i want to add a image but with different onclicks.
This is what i got now. All the "onclicks" are edited to the last for each round.
function cart(){
count = readCookie("count");
tableRow = "";
for (i = 1; i <= count; i++){
item = "item" + i;
Cookie = readCookie(item);
if (!(Cookie == null)){
row = new Array();
row = Cookie.split("|");
tableRow += "<tr>"
+ "<td>" + row[0] + "</td>"
+ "<td>" + row[1] + "</td>"
+ "<td>" + row[2] + "</td>"
+ "<td>" + row[3] + "</td>"
+ "<td>" + row[4] + "</td>"
+ "<td>" + row[5] + "</td>"
+ "<td>" + row[4] * row[5] + "</td>" + "<td>"
+ "<a href=''><img src='img/delete.png' onclick='editCart(item);'></a>"
+ "</td>" + "</tr>";
}
}
document.write(tableRow);}
I know cookies are not the best way to do it but it's a school assignment.
Thats why even if you only like to give a hint i still would appreciate it.
"<a href=''><img src='img/delete.png' onclick='editCart(item);'></a>"
Every onclick call will be the same.
"<a href=''><img src='img/delete.png' onclick='editCart(\""+item+"\");'></a>"
This will generate the outputlink dynamically.
I have button to add new row(s) to table.
In the table row have a column with touch spin.
I want to loop through Array(Items). to make a rows. But below code make a Error Uncaught TypeError: undefined is not a function at function tp0
function showtable() {
$('#showtable').html("");
for(var i in Items) {
var no = parseInt($('#tb tr').length) - 1;
var data = "<tr role='row' class='filter' >"
+ "<td>" + no
+ "</td>"
+ "<td>"
+ "<div class='form-group'>"
+ "<input id='touch" + i + "' type='text' value='1' name='touch" + i + "' /> "
+ "<script>"
+ "function tp" + i + " () {$(\"input[name=\'touch" + i + "\']\").TouchSpin(); alert('ttt');}"
+ "</scr" + "ipt>"
+ "</div>"
+ "</td>"
+ "</tr>";
$('#showtable').append(data);
var method_name = "tp";
window[method_name + i]();
}
}
Have any ideas thanks
Instead of adding functions like that with each row, you should just pass the row number as a variable to a predefined function:
function tp(index) {
$("input[name='touch" + index + "']").TouchSpin();
alert('ttt');
}
function showtable() {
$('#showtable').html("");
for (var i in Items) {
var no = parseInt($('#tb tr').length) - 1;
var data = "<tr role='row' class='filter' >"
+ "<td>" + no
+ "</td>"
+ "<td>"
+ "<div class='form-group'>"
+ "<input id='touch"+i+"' type='text' value='1' name='touch"+i+"' /> "
+ "</div>"
+ "</td>"
+ "</tr>";
$('#showtable').append(data);
tp(i);
}
}
Hi I'm stumped as to why the data in my table is returned undefined. I think I'm close.
Please check out my jsfiddle:
$(document).ready(function() {
$.getJSON( "http://www.corsproxy.com/dvl.thomascooper.com/data/json_return.json", function( data ) {
//static table head
$('table.stats').append("<th>" + "</th>" + "<th>" + "Date" + "</th>" + "<th>" + "Brand" + "</th>" + "<th>" + "Author" + "</th>" + "<th>" + "Title" + "</th>" + "<th>" + "Posts" + "</th>" + "<th>" + "Exposure" + "</th>" + "<th>" + "Engagement" + "</th>");
//loop through json data
$.each(data.data.rows,function( i, val ){
//+1 to number each row starting at 1
var rowNum = i + 1;
//create table rows and cell and populate with data
$('table.stats').append( "<tr>" + "<td>" + rowNum + "</td>" + "<td>" + val.date + "</td>" +"<td>" + val.brand_id + "</td>" + "<td>" + val.author + "</td>" + "<td>" + val.title + "</td>" + "<td>" + val.posts + "</td>" + "<td>" + val.reach + "</td>" + "<td>" + val.interaction + "</td>" + "</tr>");
});
});
});
fiddle: http://jsfiddle.net/tommy6s/eLbq2wvh/
$.each(data.data.rows,function( i, val ) {
Here, val is not object (Your data told me that)
So you could not access property that undefined like this: val.date
I think, here is what you want:
$(document).ready(function() {
$.getJSON( "http://www.corsproxy.com/dvl.thomascooper.com/data/json_return.json", function( data ) {
//static table head
$('table.stats').append("<th>" + "</th>" + "<th>" + "Date" + "</th>" + "<th>" + "Brand" + "</th>" + "<th>" + "Author" + "</th>" + "<th>" + "Title" + "</th>" + "<th>" + "Posts" + "</th>" + "<th>" + "Exposure" + "</th>" + "<th>" + "Engagement" + "</th>");
//loop through json data
$.each(data.data.rows,function( i, val ){
//+1 to number each row starting at 1
var rowNum = i + 1;
//create table rows and cell and populate with data
$('table.stats').append( "<tr>" + "<td>" + rowNum + "</td>" + "<td>" + val[0].value + "</td>" +"<td>" + val[1].value + "</td>" + "<td>" + val[2] + "</td>" + "<td>" + val[3].label + "</td>" + "<td>" + val[4].values[0] + "</td>" + "<td>" + val[5].values[0] + "</td>" + "<td>" + val[6].values[0] + "</td>" + "</tr>");
});
});
});
If you look at the returned json - rows is an array of arrays not an array of objects.. You failed to take this into consideration.
$.each(data.data.rows[0],function( i, val ){
Also you are trying to access the value of the data by its value instead of by its key.
"<td>" + val.field + "</td>" +"<td>" + val.type + "</td>"
Checkout this jsbin for example
You are trying to reference the data as if it were:
rows: [ { date: '', brand_id: '', author: '', etc }, next set of fields]
What you are actually getting is:
rows: [ [ object with field data, object with field data, etc], another array of field data objects, etc]
Here is a beginning to a script that will be flexible in how things will be returned. I've left out many of the cases you'll need to deal with:
//loop through json data
$.each(data.data.rows,function( i, val ){
//+1 to number each row starting at 1
var rowNum = i + 1, fields = {};
// Find fields
$.each(val, function(j, fieldData) {
if(typeof fieldData == 'string') {
fields.author = fieldData;
} else if(fieldData.field == 'title') {
fields.title = fieldData.label;
} else {
fields[fieldData.field] = fieldData.value;
}
});
//create table rows and cell and populate with data
$('table.stats').append( "<tr>" + "<td>" + rowNum + "</td>" + "<td>" + fields.date + "</td>" +"<td>" + fields.brand_id + "</td>" + "<td>" + fields.author + "</td>" + "<td>" + fields.title + "</td>" + "<td>" + fields.posts + "</td>" + "<td>" + fields.reach + "</td>" + "<td>" + fields.interaction + "</td>" + "</tr>");
});
