jQuery to emulate iPhone password input changes textbox to disabled in a Visual Studio web application

I am working on a web application in Visual Studio using visual basic and master pages. I have 10 textbox fields on a child page where I would like to emulate the iPhone password entry (ie. show the character entered for a short period of time then change that character to a bullet). This is the definition of one of the text box controls:
<asp:TextBox ID="txtMID01" runat="server" Width="200" MaxLength="9"></asp:TextBox>
At the bottom of the page where the above control is defined, I have the following:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript" src="lib/jQuery.dPassword.js"></script>
<script type="text/javascript">
$(function () {
var textbox01 = $("[id$=txtMID01]");
alert(textbox01.attr("id"));
$("[id$=txtMID01]").dPassword()
});
</script>
When the page loads, the alert displays MainContent_txtMID01 which is the ID of the control preceeded with the name of the content place holder.
The following is the contents of lib/jQuery.dPassword.js (which I found on the internet):
(function ($) {
$.fn.dPassword = function (options) {
var defaults = {
interval: 200,
duration: 3000,
replacement: '%u25CF',
// prefix: 'password_',
prefix: 'MainContent_',
debug: false
}
var opts = $.extend(defaults, options);
var checker = new Array();
var timer = new Array();
$(this).each(function () {
if (opts.debug) console.log('init [' + $(this).attr('id') + ']');
// get original password tag values
var name = $(this).attr('name');
var id = $(this).attr('id');
var cssclass = $(this).attr('class');
var style = $(this).attr('style');
var size = $(this).attr('size');
var maxlength = $(this).attr('maxlength');
var disabled = $(this).attr('disabled');
var tabindex = $(this).attr('tabindex');
var accesskey = $(this).attr('accesskey');
var value = $(this).attr('value');
// set timers
checker.push(id);
timer.push(id);
// hide field
$(this).hide();
// add debug span
if (opts.debug) {
$(this).after('<span id="debug_' + opts.prefix + name + '" style="color: #f00;"></span>');
}
// add new text field
$(this).after(' <input name="' + (opts.prefix + name) + '" ' +
'id="' + (opts.prefix + id) + '" ' +
'type="text" ' +
'value="' + value + '" ' +
(cssclass != '' ? 'class="' + cssclass + '"' : '') +
(style != '' ? 'style="' + style + '"' : '') +
(size != '' ? 'size="' + size + '"' : '') +
(maxlength != -1 ? 'maxlength="' + maxlength + '"' : '') +
// (disabled != '' ? 'disabled="' + disabled + '"' : '') +
(tabindex != '' ? 'tabindex="' + tabindex + '"' : '') +
(accesskey != undefined ? 'accesskey="' + accesskey + '"' : '') +
'autocomplete="off" />');
// change label
$('label[for=' + id + ']').attr('for', opts.prefix + id);
// disable tabindex
$(this).attr('tabindex', '');
// disable accesskey
$(this).attr('accesskey', '');
// bind event
$('#' + opts.prefix + id).bind('focus', function (event) {
if (opts.debug) console.log('event: focus [' + getId($(this).attr('id')) + ']');
clearTimeout(checker[getId($(this).attr('id'))]);
checker[getId($(this).attr('id'))] = setTimeout("check('" + getId($(this).attr('id')) + "', '')", opts.interval);
});
$('#' + opts.prefix + id).bind('blur', function (event) {
if (opts.debug) console.log('event: blur [' + getId($(this).attr('id')) + ']');
clearTimeout(checker[getId($(this).attr('id'))]);
});
setTimeout("check('" + id + "', '', true);", opts.interval);
});
getId = function (id) {
var pattern = opts.prefix + '(.*)';
var regex = new RegExp(pattern);
regex.exec(id);
id = RegExp.$1;
return id;
}
setPassword = function (id, str) {
if (opts.debug) console.log('setPassword: [' + id + ']');
var tmp = '';
for (i = 0; i < str.length; i++) {
if (str.charAt(i) == unescape(opts.replacement)) {
tmp = tmp + $('#' + id).val().charAt(i);
}
else {
tmp = tmp + str.charAt(i);
}
}
$('#' + id).val(tmp);
}
check = function (id, oldValue, initialCall) {
if (opts.debug) console.log('check: [' + id + ']');
var bullets = $('#' + opts.prefix + id).val();
if (oldValue != bullets) {
setPassword(id, bullets);
if (bullets.length > 1) {
var tmp = '';
for (i = 0; i < bullets.length - 1; i++) {
tmp = tmp + unescape(opts.replacement);
}
tmp = tmp + bullets.charAt(bullets.length - 1);
$('#' + opts.prefix + id).val(tmp);
}
else {
}
clearTimeout(timer[id]);
timer[id] = setTimeout("convertLastChar('" + id + "')", opts.duration);
}
if (opts.debug) {
$('#debug_' + opts.prefix + id).text($('#' + id).val());
}
if (!initialCall) {
checker[id] = setTimeout("check('" + id + "', '" + $('#' + opts.prefix + id).val() + "', false)", opts.interval);
}
}
convertLastChar = function (id) {
if ($('#' + opts.prefix + id).val() != '') {
var tmp = '';
for (i = 0; i < $('#' + opts.prefix + id).val().length; i++) {
tmp = tmp + unescape(opts.replacement);
}
$('#' + opts.prefix + id).val(tmp);
}
}
};
})(jQuery);
When I execute my code, the code behind populates the value of the textbox with "123456789" and when the page gets rendered, all the characters have been changed to bullets, which is correct. The problem I am having is that the textbox has been disabled so I can not edit the data in the textbox.
I removed (by commenting out) the references to the disabled attribute but the control still gets rendered as disabled.
As a side note, the code that I found on the internet was originally designed to work with a textbox with a type of password but when I set the TextMode to password, not only does the control get rendered as disabled, but the field gets rendered with no value so I left the TextMode as SingleLine.
Any suggestions or assistance is greatly appreciated.
Thanks!

As far as I know, it is not possible to have it so that while you type a password, the last letter is visible for a second and then turns into a bullet or star.
However what you can do is as the user types in password, with a delay of lets say 500ms store the string the user has typed in so far into some variable and replace the content of the password field or the text field with stars or black bullets. This will give you what you are looking for.

CSS change in an addEventListener function is not applied unitl the function exits

Im trying to change the cursor logo when Im building a dynamic div. Depending on how much data it can take up a few seconds to load so I need the cursor change.
The problem Im having is that the cursor isnt changing until my code has fully executed.
Im have a dynamically generated chart with the points in the chart set to popup more data when they are clicked. This is the eventListener Ive created and it works fine apart from my CSS update not getting applied until it has exited the function.
Any idea how I can force it to update immediately
point.addEventListener('click', function (evt) {
document.body.className = 'waiting';
var evtPoint = document.getElementById(evt.currentTarget.id);
var index = evtPoint.id.substring(evtPoint.id.lastIndexOf('-') + 1, evtPoint.id.length);
var chartOptions = Charts.options[elementId];
var txnData = chartOptions.data.txn[index];
var txnFullData = chartOptions.data.txnFull;
var theDate = new Date(txnData.time);
// pop up
var txnsPerMinutePopUp = document.getElementById('txnsPerMinutePopUp');
txnsPerMinutePopUp.innerHTML = '<div id = "txnsPerMinutePopUp-bg"></div>' +
'<div id = "txnsPerMinutePopUp-body">' +
'<div id = "txnsPerMinutePopUp-body-heading"></div>' +
'<div id = "txnsPerMinutePopUp-body-txns">';
var txnsPerMinutePopUpHeading = document.getElementById('txnsPerMinutePopUp-body-heading');
var txnsPerMinutePopUpBody = document.getElementById('txnsPerMinutePopUp-body-txns');
function addZero(i) {
if (i < 10) {
i = '0' + i;
}
return i;
}
for (var i = 0; i < txnFullData.length; i++) {
// console.log("loop" + i, txnFullData);
var date = new Date(txnFullData[i].time);
if (date.getTime() === theDate.getTime()) {
txnsPerMinutePopUpHeading.innerHTML = '<div class="txnsPerMinutePopUp-body-heading-title">Tweets</div><div class="txnsPerMinutePopUp-body-heading-time">' + addZero(theDate.getHours()) + ':' + addZero(theDate.getMinutes()) + '</div>';
var child = '<div class = "txnsPerMinutePopUp-txns">' +
'<div class = "txnsPerMinutePopUp-txns-img">' +
'<object data = "' + txnFullData[i].profile_image_url + '" class = "border-rad-25 cross-series-profile-img" width = "50px" height = "50px" type = "image/jpeg">' +
'<img src = "assets/img/engager_profile_default-47.svg" class = "border-rad-25 cross-series-profile-img" width = "50px" height = "50px" alt = "' + txnFullData[i].screen_name + ' profile image" />' +
'</object>' +
'</div>' +
'<div class = "txnsPerMinutePopUp-txns-screen-name">' +
'#' + txnFullData[i].screen_name + '' +
'</div>' +
'<div class = "txnsPerMinutePopUp-txns-text">' + Charts.lineChart.parseText(txnFullData[i].text) + '</div>' +
'</div>';
txnsPerMinutePopUpBody.innerHTML += child;
}
}
txnsPerMinutePopUp.innerHTML += '</div>' +
'</div>';
//document.body.style.cursor='default';
txnsPerMinutePopUp.style.visibility = 'visible';
var bg = document.getElementById('txnsPerMinutePopUp-bg');
bg.addEventListener('click', function (evt) {
txnsPerMinutePopUp.style.visibility = 'hidden';
});
}, false);
My CSS then is just
body.waiting * { cursor: wait; }
UPDATE
From researching potential causes I found out that most browsers wont update the DOM immediately and I need to interrupt the javascript to allow for the DOM to get updated.
Ive updated my code to move the bulk of the operations out to a separate function and tried to set a timeout value on it and its still not updating the cursor until everything completes.
I also tried to add a mousedown event to try and get ahead of the javascript in the on click but it didnt work either
EventListener
point.addEventListener('click', function (evt) {
//document.body.className = 'waiting';
// setTimeout(function() {
Charts.lineChart.changeCursor();
// },10);
var evtPoint = document.getElementById(evt.currentTarget.id);
var index = evtPoint.id.substring(evtPoint.id.lastIndexOf('-') + 1, evtPoint.id.length);
var chartOptions = Charts.options[elementId];
var txnData = chartOptions.data.txn[index];
var txnFullData = chartOptions.data.txnFull;
var theDate = new Date(txnData.time);
function addZero(i) {
if (i < 10) {
i = '0' + i;
}
return i;
}
setTimeout(function() {
Charts.lineChart.breakOut( txnFullData,theDate );
},100);
document.body.style.cursor='default';
txnsPerMinuteTweetsPopUp.style.visibility = 'visible';
}, false);
and the following code was moved into the breakout function
breakOut
Charts.lineChart.breakOut = function(txnFullData,theDate){
function addZero(i) {
if (i < 10) {
i = '0' + i;
}
return i;
}
var txnsPerMinutePopUp = document.getElementById('txnsPerMinutePopUp');
txnsPerMinutePopUp.innerHTML = '<div id = "txnsPerMinutePopUp-bg"></div>' +
'<div id = "txnsPerMinutePopUp-body">' +
'<div id = "txnsPerMinutePopUp-body-heading"></div>' +
'<div id = "txnsPerMinutePopUp-body-txns">';
var txnsPerMinutePopUpHeading = document.getElementById('txnsPerMinutePopUp-body-heading');
var txnsPerMinutePopUpBody = document.getElementById('txnsPerMinutePopUp-body-txns');
for (var i = 0; i < txnFullData.length; i++) {
// console.log("loop" + i, txnFullData);
var date = new Date(txnFullData[i].time);
if (date.getTime() === theDate.getTime()) {
txnsPerMinutePopUpHeading.innerHTML = '<div class="txnsPerMinutePopUp-body-heading-title">Tweets</div><div class="txnsPerMinutePopUp-body-heading-time">' + addZero(theDate.getHours()) + ':' + addZero(theDate.getMinutes()) + '</div>';
var child = '<div class = "txnsPerMinutePopUp-txns">' +

Issue trying to escape a string in javascript plugin

I'm trying to use a Bootstrap Tab plugin for CKEditor, and it works well. But, when i use a single quote on content (doesn't matter if the string is "'", or " or '), it broke up.
I guess is just a escape issue. I tried with escape() and encodeURI(), but fails.
Error: SyntaxError: missing ) after argument list;
Source:
x)PRE3015 Pino 1/2'' 15mm Ponta Balistica Aço 3,1 15
The piece of plugin code for tabs is:
data: function() {
var bootstrapTab_d = new Date();
var bootstrapTab_id = bootstrapTab_d.getTime();
var bootstrapTab_item = bootstrapTab_contents = '';
for (var bootstrapTab_i = 0; bootstrapTab_i <= this.data.bootstrapTab_total; bootstrapTab_i++) {
eval("bootstrapTab_title = this.data.bootstrapTab_item" + bootstrapTab_i);
bootstrapTab_title = bootstrapTab_title != undefined ? bootstrapTab_title : '';
eval("bootstrapTab_content = this.data.bootstrapTab_content" + bootstrapTab_i);
bootstrapTab_content = bootstrapTab_content != undefined ? bootstrapTab_content : '';
eval("bootstrapTab_itemClass = this.data.bootstrapTab_itemClass" + bootstrapTab_i);
bootstrapTab_itemClass = bootstrapTab_itemClass != undefined ? bootstrapTab_itemClass : '';
eval("bootstrapTab_contentClass = this.data.bootstrapTab_contentClass" + bootstrapTab_i);
bootstrapTab_contentClass = bootstrapTab_contentClass != undefined ? bootstrapTab_contentClass : '';
if (bootstrapTab_title) {
bootstrapTab_item += '<li role="presentation" class="' + bootstrapTab_itemClass + '">' + bootstrapTab_title + '</li>';
bootstrapTab_contents += '<div role="tabpanel" class="' + bootstrapTab_contentClass + '" id="tab' + bootstrapTab_id + '_' + (bootstrapTab_i + 1) + '">' + bootstrapTab_content + '</div>'
}
}
this.element.setAttribute('id', 'collapse' + bootstrapTab_id);
this.element.$.innerHTML = '<div role="tabpanel"><ul class="nav nav-tabs" role="tablist">' + bootstrapTab_item + '</ul><div class="tab-content">' + bootstrapTab_contents + '</div></div>'
}

I'd refactor the code, and not use eval!
eval is evil http://blogs.msdn.com/b/ericlippert/archive/2003/11/01/53329.aspx
instead of
eval("bootstrapTab_title = this.data.bootstrapTab_item" + bootstrapTab_i);
use bootstrapTab_item as an array and do this
bootstrapTab_title = this.data.bootstrapTab_item[bootstrapTab_i]
really don't know if the error is there, but I think the path to find the error is refactor to eliminate those eval, that could be the source of your problem.

Storing data in JavaScript array

This is my jsp code where I am trying to push some data in javaScript array.
<%
int proListSize = proList.size();
ProfileDAO proDAO = null;
for(int i = 0, j=1; i < proListSize; i++){
proDAO = (ProfileDAO)proList.get(i);%>
entireArray.push(<%= proDAO.getNetworkmapId()%> + ":"+<%=proDAO.getAssetId()%> + ":" + <%= proDAO.getCode()%>);
<%} %>
And this is the function where I am trying to use it by using pop function.
function GenDemographicTag() {
var ptag = "<!-- Begin "+networkNameToUpperCase+" -->\n" ;
var t = "";
if (WhiteTagLabelDomain) {
ptag += "<iframe src=\"http://"+WhiteTagLabelDomainTrim+"/jsc/"+folderName+"/dm.html?";
} else {
ptag += "<iframe src=\"http://"+cdnName+"/jsc/"+folderName+"/dm.html?";
}
ptag += "n="+networkId+";";
for(var i = 0;i< entireArray.length;i++){
var combinedString = entireArray.splice(1,1);
var rightSide = combinedString.split(':')[0];
var middle = combinedString.split(':')[1];
var leftSide = combinedString.split(':')[2];
t = "";
if ( $("proElementEnable_"+rightSide) && $("proElementEnable_"+leftSide).checked) {
if ( middle == "1") {
if ( $("zip").value.length <= 0) {
t = "0";
} else {
t = $("zip").value;
}
} else if ( $("targetList_"+rightSide) && $("targetList_"+rightSide).length > 0 && $("targetList_"+rightSide).options[0].value != "-1") {
t = makeProelementList($("targetList_"+rightSide));
}
ptag += leftSide+"=" + t+ ";";
}
proDAO = null;
}
ptag += "\" frameborder=0 marginheight=0 marginwidth=0 scrolling=\"no\" allowTransparency=\"true\" width=1 height=1>\n</iframe>\n<!-- end "+networkNameToUpperCase+" -->\n";
document.forms[0].tag.value = ptag;
}
Basically I am trying to get the data from proList and store it in javaScript array(entireArray)...so that I can use in the javascript function..but after doing the above I get a javaScript error as follow:
entireArray.push(3 + ":"+3 + ":" + d3);
entireArray.push(185 + ":"+5 + ":" + d4);
entireArray.push(2 + ":"+2 + ":" + d2);
entireArray.push(186 + ":"+5 + ":" + d9);
entireArray.push(183 + ":"+5 + ":" + d6);
entireArray.push(184 + ":"+5 + ":" + d7);
entireArray.push(187 + ":"+5 + ":" + da);
entireArray.push(445 + ":"+5 + ":" + db);
Reference Error:d3 is not defined.
what is the exact problem..?

The return type of splice is an ARRAY , so you can try following code
var combinedString = entireArray.splice(1,1);
var rightSide = combinedString[0].split(':')[0];
var middle = combinedString[0].split(':')[1];
var leftSide = combinedString[0].split(':')[2];

d3 should be in quotes. "d3"
You need to put the out of JSP in quotes.
entireArray.push(<%= proDAO.getNetworkmapId()%> + ":"+<%=proDAO.getAssetId()%> + ":" + '<%= proDAO.getCode()%>');

It works fine on any major browsers (Chrome, FF, etc) but not on ... IE ! I've opened the console and it says : "DocumentElement is undefined ..."
I'm tired and can't fix that, any help will be very very appreciated !!
