Develop Reference

Jquery, create table tag with custom ID, then later refer to that ID and append new tags to it

So essentially I want to append a < table> tag to < body> with a custom ID and then later in my code refer to the table with the custom ID and append < tr>, < td>, or < th> to it.
Here's an example:
dataHold = data[1].split("#")[1]; //just imagine this as "yahoo.com"
if( !hold.includes( dataHold ) )
{
$("body").append
(
"<table id='"+dataHold+"'>"+
"<tr>"+
"<th>"+dataHold+"</th>"+
"</tr>"+
"</table>"
);
$( "#"+dataHold ).append
(
"<tr>"+
"<td>"+data[1]+"</td>"+
"<td>"+data[2]+"</td>"+
"<td>"+data[3]+"</td>"+
"</tr>"
);
}
It does append the < table> tag, but for some reason the < tr> tag appending doesn't work and I can't figure out why. Any ideas?

Your jQuery code is fine, so the problem is with your variables or lack of inclusion of jQuery. Ensure that you have jQuery loaded, and that your three variables (hold, data and dataHold) actually resolve. Don't forget that hold is not supposed to include dataHold for the if condition to be entered.
The following snippet shows this working as expected (with all variables set correctly):
const hold = data = [2, 3, 4, 5];
const dataHold = 1;
if (!hold.includes(dataHold)) {
$("body").append(
"<table id='" + dataHold + "'>" +
"<tr>" +
"<th>" + dataHold + "</th>" +
"</tr>" +
"</table>"
);
$("#" + dataHold).append(
"<tr>" +
"<td>" + data[1] + "</td>" +
"<td>" + data[2] + "</td>" +
"<td>" + data[3] + "</td>" +
"</tr>"
);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Your code works just fine when isolated to this snippet:
var dataHold = "testId";
var data = ["foo", "bar", "carrots", "broccoli"];
$("body").append(
"<table id='" + dataHold + "'>" +
"<tr>" +
"<th>" + dataHold + "</th>" +
"</tr>" +
"</table>"
);
$("#" + dataHold).append(
"<tr>" +
"<td>" + data[1] + "</td>" +
"<td>" + data[2] + "</td>" +
"<td>" + data[3] + "</td>" +
"</tr>"
);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Ensure that you have correctly included the jQuery library before using the jQuery selector function ('$'). Also, use the built-in debugger in your favorite browser to ensure that the values of dataHold and data are exactly what you expect them to be. If they are null or undefined you may get errors in the string concatenation resulting in your row not being appended.

one ajax loop with 2 outputs error innerHTML

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>" + (!!arr[i].app_ver ? arr[i].app_ver : '') + "</td>" +
"<td>" + (!!arr[i].app_date ? formatDateTime(arr[i].app_date, 'shortdate') : '') + "</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.

Use image in for each but with different onclicks

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.

table json data returning undefined using jQuery

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>");
});

Refresh table after using jQuery .append()

The following code gets a JSON object and then spits its contents out into a <table>. The first time I do it I get my JSON content just fine. However, when I refresh, the refreshed data is stuck onto the bottom of my table. How do I refresh the data to show the new data only? I tried using .remove() but there was an obvious deleting and then a refresh of data.
$(function() {
$('#ReportedIssue').change(function() {
//$('.data').remove()
$.getJSON('/CurReport/GetUpdatedTableResults', function(json) {
for (var i = 0; i < json.GetDocumentResults.length; i++) {
$('#DocumentInfoTable').append(
"<tr class='data'>" +
"<td>" + json.GetDocumentResults[i].Document.DocumentId + "</td>" +
"<td>" + json.GetDocumentResults[i].Document.LanguageCode + "</td>" +
"<td>" + json.GetDocumentResults[i].ReportedIssue + "</td>" +
"<td>" + json.GetDocumentResults[i].PageNumber + "</td>" +
"</tr>"
);
};
});
});
});
Thank you,
Aaron

It will be more efficient to build the HTML as follows (and of course, solves the problem you're experiencing):
$(function() {
$('#ReportedIssue').change(function() {
//$('.data').remove()
$.getJSON('/CurReport/GetUpdatedTableResults', function(json) {
var str = '';
for (var i = 0; i < json.GetDocumentResults.length; i++) {
str += "<tr class='data'>" +
"<td>" + json.GetDocumentResults[i].Document.DocumentId + "</td>" +
"<td>" + json.GetDocumentResults[i].Document.LanguageCode + "</td>" +
"<td>" + json.GetDocumentResults[i].ReportedIssue + "</td>" +
"<td>" + json.GetDocumentResults[i].PageNumber + "</td>" +
"</tr>"
};
$('#DocumentInfoTable').html(str);
});
});
});
