I try to use bootstrap 3 tooltip in my website, and use html to show the content of tooltip, but I get an error: Cannot read property 'user' of undefined.
<div class="container">
Hover over me
Hover over me
Hover over me
Hover over me
Hover over me
</div>
$(document).ready(function() {
var data = [{'user': "Amy"}, {'user': "Betty"}, {'user': "Cindy"}, {'user': "Debby"}, {'user': "Emily"}];
setTooltip(data);
})
function setTooltip(data) {
for (var i = 0; i < data.length; i++) {
$('[data-idx="' + i + '"]').tooltip({
html: true,
title: function() {
return "<p>User: " + data[i].user + "</p>";
}
});
}
}
This is the result in the console:
Does anybody have this problem? Thank you.
You will have to update your setTooltip function:
function setTooltip(data) {
for (var i = 0; i < data.length; i++) {
const name = data[i].user;
$('[data-idx="' + i + '"]').tooltip({
html: true,
title: "<p>User: " + name + "</p>"
});
}
}

});
}
}
Please try the above solution it is working fine.
The issue I found in your code that you were using a function() to set the tooltip and the data[i] was undefined within that scope.
Tested link: https://jsbin.com/viyipewale/edit?html,js
Please try this following:
function setTooltip(data) {
for (var i = 0; i < data.length; i++) {
if($('[data-idx="' + i + '"]').length > 0){//Checking the element exists or not
$('[data-idx="' + i + '"]').tooltip({
title: "User: " + data[i].user
});
}
}
}
It's working fine.

I had a multidimensional array that consists of dynamic elements per subarray. What I was trying to do was construct a bootstrap table by reading the array. To explain the table format better: If my multidimensional array is mdArray = [[name1, name2, name3, name4], [name5, name6, name7]]
I wanted to create a table of 4 columns with mdArray[0], mdArray[1], mdArray[2], mdArray[3] then create an new row when next sub-array is detected with columns mdArray[4], mdArray[5], mdArray[6]. What I have tried is below. How can I achieve this? Any help is appreciated. Thanks in advance?
mdArray = [
['name1', 'name2', 'name3', 'name4'],
['name5', 'name6', 'name7']
]
$('.table').ready(
function() {
console.log('table loaded');
var theTable = "";
for (var j = 0; j < mdArray.length; j++) {
theTable += '<tr class="text-center">';
for (var k = 0; k < 2; k++) {
theTable += '<td> class="text-center"' + mdArray[k][j] + '</td>';
}
theTable += '</tr>';
}
$('.table').append(theTable);
//expected name1 name2 name3 name4
//next row
//name5 name6 name7
});

You can use forEach loop and you don't need to worry about number of columns and handling array indexes
$('.table').ready(function() {
var theTable = "";
mdArray.forEach((names) => {
theTable += '<tr class="text-center">'
names.forEach((name) => {
theTable += `<td class="text-center">${name}</td>`;
})
theTable += '</tr>'
}
);
$('.table').append(theTable);
});

My webpage currently looks like this:
I want to know is it possible in DataTables that for 2nd & 3rd columns, I get a Filter along with the column name so that we can select for which specific values we want to view data for, something like what we have in Excel (using Sort & Filter)?? Please help!!
Yes, it is possible with a customized solution.
You need to read all columns and add distinct members to dropdowns like this.
$(document).ready(function() {
$('#example').DataTable( {
initComplete: function () {
this.api().columns().every( function () {
var column = this;
var select = $('<select><option value=""></option></select>')
.appendTo($(column.header()).empty())
.on('change', function () {
var val = $.fn.dataTable.util.escapeRegex(
$(this).val()
);
column
.search( val ? '^'+val+'$' : '', true, false )
.draw();
});
column.data().unique().sort().each( function ( d, j ) {
select.append( '<option value="'+d+'">'+d+'</option>' )
});
});
}
});
});
By using column().search() functionality, you will have a column based filter with dropdowns. You can move dropdowns from header to footer by changing .appendTo($(column.header()).empty()) to .appendTo($(column.footer()).empty()).
Examples:
jsFiddle (header dropdowns)
jsFiddle (footer dropdowns)
Below demo app is showing three different progressbars.
Now user needs to select which progressbar he/she wants to change value
and then on button click which is provided at same page.
var app = angular.module('myApp',[]);

'</select>' +
'</span>' +
'<span ng-repeat="btn in $ctrl.obj.buttons">' +
'<button class="btn" ng-click="$ctrl.changeProgress(btn, $ctrl.selectedProgressbar)">{{btn}}</button>' +

'</div>',
controller: function () {
this.obj = {
"buttons": [
10,
38,
-13,

var selectedBar = this.selectedProgressbar;

// this.obj.bars[0] = parseInt(this.obj.bars[0]) + parseInt(val);
// if we remove comment from above code and comment below one then progresbar value changes at same time
// but with below code its not changing at same time its changing when we click on any button or change progreebar selection

clearInterval(update);
}

bars[selectedBar] = barValue;
}, 15);
}
}
this.changeProgress = changeProgressbar;

jsBin is here,
now after selecting any progressbar then click on any first two buttons then no change is found on progreebar
but as soon as you click again or select some other progressbar then value is changing.
After going through your code, I found some issues there.
You should change the changeProgressbar function and remove the interval function.

PLEASE RUN THE ABOVE SNIPPET
Here is a working DEMO
I'm very new to both JQuery and Javascript. I have an feed, I would like to display these feed inside a collapsible div AS a collapsible div. I have the following Javascript file:
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("feeds", "1");
google.setOnLoadCallback(showFeed);
function showFeed() {
var feed = new google.feeds.Feed("http://www.varzesh3.com/rss");
feed.setNumEntries(10);
feed.load(function(result) {
if (!result.error) {
var container = document.getElementById("headlines");
for (var i = 0; i < result.feed.entries.length; i++) {
var entry = result.feed.entries[i];
var di = document.createElement("div").setAttributeNode("data-role", "collapsible");
di.innerHTML = '<h3>' + entry.title + '</h3>';
di.innerHTML += '<p>' + entry.contentSnippet + '</p>';
container.appendChild(di);
}
} else {
var container = document.getElementById("headlines");
container.innerHTML = '<li>Get your geek news fix at site</li>';
}
});
}
</script>
<body>
<div data-role="collapsible-set" id="headlines"></div>
</body>
This should fetch all my feed names and put them in a collapsible div, it does exactly that but it shows the names as plain HTML text instead of a JQuery Mobile collapsible div.
#AML, that is more a comment than an answer because a don't analyse your entire code, but I will put here for formatting purposes.
In the line:
var di = document.createElement("div").setAttributeNode("data-role", "collapsible");
You don't take a pointer(di) to the new created element, you take a result of the setAttributeNode(...), You need to split the code in two lines like that:
var di = document.createElement("div");
di.setAttribute("data-role", "collapsible");
There are a problem with setAttributeNode actually is setAttribute.
Now is working, see at http://pannonicaquartet.com/test/feeds.html

I am trying to get tweets from different zip codes.For doing this, I am using latitude and longitude values for each zip code. So far I want to get 3 tweets for each zip code(I have 2 zip codes), but it is working only for one zip code.
Any suggestion will be appreciated. Thank you in advance!

I found 2 problems with your code:
1) If you want to iterate 2 times, your for function should be like this: for (var i = 0; i < 2; i++)
2) You must have in consideration that the function that gets called in $.getJSON runs asynchronously, so when that function gets called the for will have already finished, therefore you can't use the i value with that purpose inside that function.
So, after correcting those 2 things in your code you should be able to get what you want. Try with something like this:
