I have written the script as follows:
<script type="text/javascript">
$(document).ready(function(){
$("#Click").click(function(){
var data1 = new Object();
data1.name = $('#databases').val();
$.ajax({
url : "form_submit",
type : 'POST',
data : data1,
dataType : "text",
success : function(data){
data = JSON.parse(data);
var output="<table id=tableStyle>";
output+="<tr>" + "<th>" + "REPORTSUITE_ID" + "</th>" + "<th>" + "REPORTSUITE_NAME" + "</th>" + "<th>" + "STAGING_DATABASE" + "</th>" + "<th>" + "DWH_DATABASE" + "</th>" + "</tr>";
for (var i in data)
{
output+="<tr>" + "<td>" + data[i].REPORTSUITE_ID + "</td>" + "<td>" + "<button type = \"buttion\" id =\"tableList\">" + data[i].REPORTSUITE_NAME + "</button>" + "</td>" + "<td>" + data[i].STAGING_DATABASE + "</td>" + "<td>" + data[i].DWH_DATABASE + "</td>" + "</tr>";
}
output += "</table>";
document.getElementById("placeholder").innerHTML=output;
}
});
});
});
$("#tableList").click(function(){
alert("this is data");
});
</script>
On the clicking of button with id = tableList, i want the alert with message "this is data" to be displayed but it does not display anything.
I also tried with pasting the code related to click of button with id tableList between different tags, still it did not work.
Please help
Hi used event delegation for the above question as pointed out as follows:
<script>
$(document).on("ready",function(){
$("#placeholder").on("click","button",function(event){
alert("id is " + this.id + "for database " + $('#databases').val())
})
});
</script>
The value is being passed correctly. Thanks for the pointer.

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 am making a live data portal in which I have to display live data using Ajax in asp.net using c#.
I have one table and a div which contains data but in different way/different style.
Every time my page loads after 4 secs of time to show updated data i.e table and div both refreshes to have updated data.
Initially when page loads first time, I have displayed table to show data and hiden the data which is in div's form, if I clicked button(toggle button) it will display data in div's form and hide table data.
Now problem is that when I clicked toggle button it does not display's data in div form but it reloads whole java script
and display data in table every time when I clicked the button.
I want to toggle between table and a div.
Below I have my code what I have done so far.
Please help me what I have done wrong.
Thank You.
Note Data comes from db which is SQL.

Problem
Your page reload since the button tag has by default type='submit' and that will refresh the page.
Solution
You should define your type as type='button' to prevent that behavior, e.g :
<button type='button'>Toggle Data</button>
Hope this helps.
Try to add a "return false;" at the end of your click button:
$('button').live('click', function () {
$('#div_f').toggle();
$('#liveData').toggle();
return false;
});
I am building an application that would allow adding tasks to the list,
and I want to add an edit button, that would allow user to edit each item from the list and then save or delete the amended item. Basically I want my .append code to attach an "Edit" button to each row.
Here is my current .append code
var id_counter = 0;
if ( valid ) {function increment(){id_counter++;} increment();
var $task = $("<div class='taskList' id='"+ id_counter +"'><ul class='taskScreen2'><tr>"
+ "<td><h1>" + type.val() + "</h1></td>"
+ "<td class='title'><h3>" + title.val() + "</h3></td>"
+ "<td>" + wordcount.val() + "</td>"
+ "<td><p>" + description.val() + "</p></td>"
+ "<td>" + deadline.val() + "</td>"
+"<td><button onclick='edit("+id_counter+")'>"+"edit"+"</button></td>"
+ "</tr></ul></div>"
).appendTo("#tasks2 tbody");
I don't know if I understood the question properly, but I think this should do what you like.
if ( valid ) {
var $task = $("<tr class='taskList'>"
+ "<td><h1>" + type.val() + "</h1></td>"
+ "<td class='title'><h3>" + title.val() + "</h3></td>"
+ "<td>" + wordcount.val() + "</td>"
+ "<td><p>" + description.val() + "</p></td>"
+ "<td>" + deadline.val() + "</td>"
//new button
+ "<td><button onclick='edit()'>"+ "Edit" + "</button></td>"
+ "</tr>"
).appendTo("#tasks2 tbody");
if you want to act differently depending on the row, you could call the edit function with a parameter. e.g edit(row_id)
EDIT
var id_counter
var $task = $("<tr class='taskList' id='"+ id_counter +"'>"
for the addition of the id in the code and
+"<td><button onclick='edit("+id_counter+")'>"+"edit"+"</button></td>"
for the button code
you could start with id_counter = 0; and then add plus one each time
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>");
});
