I'm making instagram API that should retrieve user accounts that contain a given keyword, the code worked well at first, but when i inserted the part of the loading gif it didn't work, the gif just kept appearing without any result
here is my code
<!DOCTYPE html>

$(document).on("mouseover", "#instaUser img", function() {
$(this).css('opacity', '0.5');
});
$(document).on("mouseout", "#instaUser img", function() {
$(this).css('opacity', '1');
});
var keyword;
var arr=new Array();
var time;
function getUsers() {
keyword=document.getElementById("search").value;
document.getElementById("name").innerHTML = keyword;
//retrieve user accs
$.ajax({
type: "POST",
url: "get_info.php?keyword='+keyword+"&"count=20",
beforeSend: function()
{
$('#images').html("<img src='ajax-loader.gif'/>");
},
success: function(data)
{
$.getJSON('get_info.php?keyword='+keyword,function(data){
$("#instaUser").empty();
$( "#images" ).fadeOut( "fast" );
$("#instaUser").empty();
// this is where we can loop through the results in the json object
for (var i = 0; i <20; i++){
if(i%4==0)
$("#instaUser").append("<br>");
$("#instaUser").append("<figure style='display:inline-block'><img id='"+i+"' src='"+data.data[i].profile_picture+"' alt='pic number "+i+"' height='"+200+"' width='"+200+"'> <figcaption>#"+data.data[i].username+"</figcaption></figure>");
// $("#instaUser").append("");
}//end for
$( "#images" ).fadeIn( "slow" );
});//end getJSON
}
});
}

I have a form in which users can submit issues, what I want to happen is when users hit the add button, i want what they add to be posted in the box below. So say the add something, x out the window and come back to add something else later what they added previously will still be there.
here is my fiddle

You could have the form 'post' to its self then make an ajax request for their new issue and put it inside a div. I would also hold off on so much on the javascript or have support for those without it:
getissues.php
getissues.php
<?php
/*
connect to your database code
*/
$query = "select * from issues";
$result = mysql_query($query, $connect);
while($row = mysql_fetch_array($result))
{
echo $row['issues'];
echo '<hr>';
}
?>
process.php
process.php:
<?php
/*
connect to your database
*/
$issue = strip_tags$_POST['issue'];
$query = "insert into issues (issue) values ('$issue')";
$result = mysql_query($query, $connect);
?>
main form page:

{
var request = $.ajax({

dataType: "html"
});
request.done(function(msg) {
$("#issues").html(msg);
});
request.fail(function(jqXHR, textStatus) {
alert( "Request failed: " + textStatus );
});
}
function validate()
{
var issue = $("#issue");
var errcount = 0;
if (issue == "")
{
errcount++;
alert("enter something");
}
if (errcount == 0)
{
/*
make request to php script to put issue into database
*/
$.post("process.php",
{
issue:issue
},
function(data,status){
window.alert("Request done!");
check();
});
}
}
</script>

How to display queued messages one after another with delay in the same div? Current solution is bad because is showing instantly new divs.
HTML:
<div id="alert-bar-container"></div>
<button id="show">First message</button>
<button id="next">Next message</button>
JavaScript:
var timeout;
$("#show").click(function () {
alertBar("this appears first");
});
$("#next").click(function () {
alertBar("this should wait and show after first disappeared");
});
function alertBar(msg) {
var message_span = $('<span />').html(msg);
var wrap_bar = $('<div />').addClass('alert_bar');
$('#alert-bar-container').html(wrap_bar.append(message_span).hide());
clearTimeout(wrap_bar.data("timer"));
wrap_bar.clearQueue();
if (wrap_bar.filter(":hidden").length == 1) wrap_bar.fadeIn('fast');
wrap_bar.data("timer", setTimeout(function () {
wrap_bar.fadeOut("slow");
wrap_bar.remove();
}, 2500));
}
Example: http://jsfiddle.net/LsRK8/
Try:
HTML:
<div id="container">
<div class="msg active">first</div>
<div class="msg">second</div>
<div class="msg">third</div>
<div class="msg">fourth</div>
</div>
JS:
setInterval(function(){
var active = $("#container").find(".active");
var i = $(active).index();
var len = $("#container").find(".msg").length;
var next;
if(i == (len-1)){
next = $("#container").find(".msg:first");
}
else{
next = $("#container").find(".msg:eq("+(i+1)+")");
}
$(active).removeClass("active").hide();
$(next).addClass("active").fadeIn();
},3000);
Fiddle here.
Hope this helps...edited with no button...

I have created a web app. I have tried my level best to trace out why does the div named more gets hidden when the an item is searched(you can see my efforts from the comments and alerts) but I was unable to trace it. I will be thankful if anyone can guide me. Thanks

Your problem is:
$("#more").appendTo("#data");
At first more sitting in data_container, then you move it to the data by this line : $("#more").appendTo("#data"); then when he comes again to success it deletes more together with data by this line: $("#data").empty(); and when you want to do again $("#more").appendTo("#data"); is not found.
I think you should change to:
$("#more").appendTo("#data_container");
Or save more before you do $("#data").empty(); in variable and then append the variable to data.
Am using the below script to change the color of the script but showing 'font color="red">Hello world /font> like this.Is any possible way to change the alert text color..
<html>
<head>
<title>JavaScript String fontcolor() Method</title>
</head>
<body>
<script type="text/javascript">
var str = new String("Hello world");
alert(str.fontcolor( "red" ));
</script>
</body>
</html>
No. alert() accepts a string and renders it using a native widget. There is no provision to style it.
The closest you could get would be to modify the HTML document via the DOM to display the message instead of using an alert().
You can use JQuery to resolve your Problem

How to do this ?
On click of ADD Comment button post that comment to your action to save it to Database or wherever you want to save, and then return that comment in call back function of ajax to show it on page.
$('#addCommentButtonID').click( function() {
$.ajax({
type:'post',
url: 'SaveComments' //url to your action method
dataType: 'json',
data: {'comments':$('#textboxId').val()},
success: function(data)
{
$('#yourMainDiv').appendChild("<div>"+data.msg+"</div>");
}
});
});
Second way :
$('#addCommentButtonID').click( function() {
$.post('SaveComments',comments:$('#commentTextbox').val(),
function (data) {
$('#yourMainDiv').appendChild("<div>"+data.msg+"</div>");
},'json');
});
Your Action
public JsonResult SaveComments(string comments)
{
// save it wherever you want
// after saving success return this string as jsonresult
return Json(new { sc = true, msg = comment });
}
