I'm trying to improve myself by working on codes. I can understand its normal state without any problems. In the sample code below, jquery, value reading, value assignment and if-else queries are nested. I could not get the code in a meaningful readable way. Can anyone write the code below in a simple expanded readable format?
$('.input-required input, .input-required select, .input-required textarea').on('focusin keyup', function () {
var inputSpan = $(this).parent().find('span').text();
$(this).val() != inputSpan && '' != $(this).val() && $(this).parent().find('span').addClass('input-style-1-active').removeClass('input-style-1-inactive'),
'' === $(this).val() && $(this).parent().find('span').removeClass('input-style-1-inactive input-style-1-active')
});
$('.input-required input, .input-required select, .input-required textarea').on('focusout', function () {
$(this).parent().find('span').text();
'' === $(this).val() && $(this).parent().find('span').removeClass('input-style-1-inactive input-style-1-active'),
$(this).parent().find('span').addClass('input-style-1-inactive')
});
The extended version of the first code block is correct as below?
$('.input-required input, .input-required select, .input-required textarea').on('focusin keyup', function () {
var inputSpan = $(this).parent().find('span').text();
if(($(this).val() != inputSpan) && ('' != $(this).val())){
$(this).parent().find('span').addClass('input-style-1-active').removeClass('input-style-1-inactive');
}else{
$(this).parent().find('span').removeClass('input-style-1-inactive input-style-1-active');
}
});
Whoever wrote that did not write it with maintenance in mind. Is it generated code by some tool?
I would think it could be condensed to
$(':input.input-required').on('input focusout', function (e) {
let $inputSpan = $(this).parent().find('span'),
text = $inputSpan.text(),
val = $(this).val();
if (val && val != text) {
$inputSpan
.addClass('input-style-1-active')
.removeClass('input-style-1-inactive')
}
else {
$inputSpan
.removeClass('input-style-1-active')
.addClass('input-style-1-inactive')
}
});
Which may be even more readable with toggleClass
Guys I know this question has been asked here many time but still I wasn't able to find a solution to my problem. I have a textarea in my asp.net mvc application which has a placeholder in it.
<textarea placeholder="Write Query..." maxlength="1000"></textarea>
Now Internet Explorer 8 & 9 doesn't support the placeholder property so I need some workaround for it, I have search here and google and found various javascripts but unfortunately none of those worked. Although some worked (as the showed the placeholder text) but the text didn't disappear on writing in the textArea
Two of those scripts (that worked half right) are these :
$(function () {
if (!$.support.placeholder) {
var active = document.activeElement;
$('input[type="text"], textarea').focus(function () {
if ($(this).attr('placeholder') != '' && $(this).val() == $(this).attr('placeholder')) {
$(this).val('').removeClass('hasPlaceholder');
}
}).blur(function () {
if ($(this).attr('placeholder') != '' && ($(this).val() == '' || $(this).val() == $(this).attr('placeholder'))) {
$(this).val($(this).attr('placeholder')).addClass('hasPlaceholder');
}
});
$('input[type="text"], textarea').blur();
$(active).focus();
$('form').submit(function () {
$(this).find('.hasPlaceholder').each(function () { $(this).val(''); });
});
}
});
Second :
$(function () {
if ($.browser.msie && $.browser.version <= 9) {
$("[placeholder]").focus(function () {
if ($(this).val() == $(this).attr("placeholder")) $(this).val("");
}).blur(function () {
if ($(this).val() == "") $(this).val($(this).attr("placeholder"));
}).blur();
$("[placeholder]").parents("form").submit(function () {
$(this).find('[placeholder]').each(function () {
if ($(this).val() == $(this).attr("placeholder")) {
$(this).val("");
}
})
});
}
});
try to this alternative
https://github.com/parndt/jquery-html5-placeholder-shim/
i think it's can manage by meta tag
Is there any way to have something similar to emptyText in input fields as in ExtJS?
I tried setting values with changed CSS. But, the value is submitted with the form and it is not disappearing as soon as I click the input field. I need to support IE7 and above
Any help would be appreciated.
What you are looking for is placeholder..W3School
<input type="text" placeholder="Hii" />
You can find polyfills for ie and old versions of other browser who don't support placeholder..
You can add this code for browser who dont support placeholder to make it work same way it works in good browsers..*It needs JQuery
// This adds 'placeholder' to the items listed in the jQuery .support object.
jQuery(function() {
jQuery.support.placeholder = false;
test = document.createElement('input');
if('placeholder' in test) jQuery.support.placeholder = true;
});
// This adds placeholder support to browsers that wouldn't otherwise support it.
$(function() {
if(!$.support.placeholder) {
var active = document.activeElement;
$(':text').focus(function () {
if ($(this).attr('placeholder') != '' && $(this).attr('placeholder') != undefined && $(this).val() == $(this).attr('placeholder')) {
$(this).val('').removeClass('hasPlaceholder');
}
}).blur(function () {
if ($(this).attr('placeholder') != '' && $(this).attr('placeholder') != undefined && ($(this).val() == '' || $(this).val() == $(this).attr('placeholder'))) {
$(this).val($(this).attr('placeholder')).addClass('hasPlaceholder');
}
});
$(':text').blur();
$(active).focus();
$('form:eq(0)').submit(function () {
$(':text.hasPlaceholder').val('');
});
}
});
Rajat answer is correct, but only for HTML5.
You can look at this question if you want an answer that work on IE (and other browsers) using only pure javascript without any library.
I am using HTLM5 placeholder and added modernizr.js to make it work in IE. The code segment is :
<input type="password" placeholder="Password">
function hasPlaceholderSupport() {
var input = document.createElement('input');
return ('placeholder' in input);
}
$(document).ready(function(){
if(!Modernizr.input.placeholder){
$('[placeholder]').focus(function() {
var input = $(this);
if (input.val() == input.attr('placeholder')) {
input.val('');
input.removeClass('placeholder');
}
}).blur(function() {
var input = $(this);
if (input.val() == '' || input.val() == input.attr('placeholder')) {
input.addClass('placeholder');
input.val(input.attr('placeholder'));
}
}).blur();
$('[placeholder]').parents('form').submit(function() {
$(this).find('[placeholder]').each(function() {
var input = $(this);
if (input.val() == input.attr('placeholder')) {
input.val('');
}
})
});
}
});
It is working fine for other browser and i want to display the text for input type password in IE but instead it puts the placeholder in the masking characters. How can the "Password" text be displyed.
The problem is that your placeholder fallback script is using the field's value to show the placeholder.
Password fields, of course, hide their value, so this technique will fail on password fields in exactly the way you described.
What you need is a placeholder script which works by writing the placeholder text into an extra element which is overlaid on top of the field (or behind it if the field's background is transparent). The script can then alter this element, rather than altering the field's value.
There are a whole load of scripts available which do exactly this - this one, for example (but there are many others too).
The other option is to dynamically change the field type from password to text and back again whenever the placeholder is toggled. This might be a quicker win to fit into your existing code, but I'd recommend using the other technique instead for the long term.
Hope that helps.
Try using this code... I hope it will help you.

I know there is a ton of placeholder questions, but I am trying to perfect mine.
My current code works great and does what it's supposed to. The problem is, when I go to place the "password" placeholder, it puts the placeholder in the masking characters. Any ideas on how to get around that?
$(function() {
if(!$.support.placeholder) {
var active = document.activeElement;
$(':text').focus(function () {
if ($(this).attr('placeholder') != '' && $(this).val() == $(this).attr('placeholder')) {
$(this).val('').removeClass('hasPlaceholder');
}
}).blur(function () {
if ($(this).attr('placeholder') != '' && ($(this).val() == '' || $(this).val() == $(this).attr('placeholder'))) {
$(this).val($(this).attr('placeholder')).addClass('hasPlaceholder');
}
});
$(':text').blur();
$(active).focus();
$('form').submit(function () {
$(this).find('.hasPlaceholder').each(function() { $(this).val(''); });
});
var active = document.activeElement;
$(':password').focus(function () {
if ($(this).attr('placeholder') != '' && $(this).val() == $(this).attr('placeholder')) {
$(this).val('').removeClass('hasPlaceholder');
}
}).blur(function () {
if ($(this).attr('placeholder') != '' && ($(this).val() == '' || $(this).val() == $(this).attr('placeholder'))) {
$(this).val($(this).attr('placeholder')).addClass('hasPlaceholder');
}
});
$(':password').blur();
$(active).focus();
$('form').submit(function () {
$(this).find('.hasPlaceholder').each(function() { $(this).val(''); });
});
}
});
My field for the pass:
<div id="loginform_pass"><input class="login" tabindex="2" type="password" placeholder="Password" name="password" maxlength="30"></div>
You could also try this... it detects that the browser does not have support for placeholder and works for all input types
function FauxPlaceholder() {
if(!ElementSupportAttribute('input','placeholder')) {
$("input[placeholder]").each(function() {
var $input = $(this);
$input.after('<input id="'+$input.attr('id')+'-faux" style="display:none;" type="text" value="' + $input.attr('placeholder') + '" />');
var $faux = $('#'+$input.attr('id')+'-faux');
$faux.show().attr('class', $input.attr('class')).attr('style', $input.attr('style'));
$input.hide();
$faux.focus(function() {
$faux.hide();
$input.show().focus();
});
$input.blur(function() {
if($input.val() === '') {
$input.hide();
$faux.show();
}
});
});
}
}
function ElementSupportAttribute(elm, attr) {
var test = document.createElement(elm);
return attr in test;
}
Could you just swap out the original text field with a password field?
$('#pass').focus(
function(){
var pass = $('<input id="pass" type="password">');
$(this).replaceWith(pass);
pass.focus();
}
);
<input id="pass" type="text" value="Passowrd">

I ran into this problem with IE before. Here's my solution :)
http://jsfiddle.net/mNchn/
If I'm understanding this right, you want the field to say "Password" when nothing has been typed into it; however, "Password" gets displayed as "********".
A decent fix to that (which also degrades gracefully, depending on how you code it) is to:
Put a LABEL before the password INPUT. Set the LABEL's text to "Password", and set its for attribute to point to the INPUT's ID, so that the INPUT is focused when the LABEL is clicked.
Use CSS to position the LABEL on top of the INPUT, so that they overlap, and it looks like "Password" is inside of the INPUT.
Make it so that the LABEL is only visible when some CSS class (.showMe, for example) is applied to it.
Use JavaScript to hide the LABEL
...if the INPUT's value is an empty string
...or if the user has selected (focused) the INPUT.
Depending on whether or not you want to be able to dynamically change the text inside the placeholder, your simplest solution might be to have the placeholder text be an image.
input {
background: url(_img/placeholder.png) 50% 5px no-repeat;
.
.
.
}
input:focus {
background: none;
}
Clearly there are many different ways of using this method, and you will have to use some kind of a fix to get :focus to work on the browsers that don't support it.
Here my plugin :
if(jQuery.support.placeholder==false){
// No default treatment
$('[placeholder]').focus(function(){
if($(this).val()==$(this).attr('placeholder'))
$(this).val('');
if($(this).data('type')=='password')
$(this).get(0).type='password';
});
$('[placeholder]').blur(function(){
if($(this).val()==''){
if($(this).attr('type')=='password'){
$(this).data('type','password').get(0).type='text';
}
$(this).val($(this).attr('placeholder'));
}
}).blur();
}
I had the same problem so i wrote a little plugin
$.fn.passLabel = function(){
var
T = $(this),
P = T.find('input[type=password]'),
V = pass.val();
P.attr('type','text');
P.focus(function(){
if(V == "")
P.attr('type','password');
});
}
now you just call it for the from at it will find all input fields with the password
attribute.
eg.
$('form').passLabel();
A bit late however same here, i was working on the issue too IE9 doesnot show the password placeholder as text, in almost all the answers on the internet some suggest changing the type some but if u do this u will have another issue on the login page like when you will see with double click on password field as its type changed to text from password, btw it works with prop. e.g. prop("type","password") if you want to change the type of an element.
on the other hand i think most answers come from a single solution its like focus and blur actions of elements. but when u apply this plugin other text fields will also be effected there is no specific or i can say generlized solution, i have still a minor issue on the login page with the password field but its showing the text correctly. anyway. here is how i have configured, copied,changed and/or another inherited anwers here.
(function($) {
$.fn.placeholder = function() {
$('input[placeholder], textarea[placeholder]').focus(function() {
var input = $(this);
if (input.val() === input.attr('placeholder')) {
if (input.prop("id") === "password") {
input.prop("type", "password");
}
input.val('');
input.removeClass('placeholder');
}
}).blur(function() {
var input = $(this);
if (input.val() === '' || input.val() === input.attr('placeholder')) {
input.addClass('placeholder');
if (input.prop("type") === "password") {
input.prop("type", "text");
}
input.val(input.attr('placeholder'));
}
}).blur().parents('form').submit(function() {
$(this).find('input[placeholder], textarea[placeholder]').each(function() {
var input = $(this);
if (input.val() === input.attr('placeholder')) {
input.val('');
}
});
});
};
})(jQuery);
still an active prolem ... :D
