Answer 1

Try this, is jquery pluin for placeholder in browser that don't support perfectly it. Leaving your php code and adding this js it should work:

(function($) {

/**
 * Spoofs placeholders in browsers that don't support them (eg Firefox 3)
 * 
 * Copyright 2011 Dan Bentley
 * Licensed under the Apache License 2.0
 *
 * Author: Dan Bentley [github.com/danbentley]
 */

// Return if native support is available.
if ("placeholder" in document.createElement("input")) return;

$(document).ready(function(){
    $(':input[placeholder]').not(':password').each(function() {
        setupPlaceholder($(this));
    });

    $(':password[placeholder]').each(function() {
        setupPasswords($(this));
    });

    $('form').submit(function(e) {
        clearPlaceholdersBeforeSubmit($(this));
    });
});

function setupPlaceholder(input) {

    var placeholderText = input.attr('placeholder');

    setPlaceholderOrFlagChanged(input, placeholderText);
    input.focus(function(e) {
        if (input.data('changed') === true) return;
        if (input.val() === placeholderText) input.val('');
    }).blur(function(e) {
        if (input.val() === '') input.val(placeholderText); 
    }).change(function(e) {
        input.data('changed', input.val() !== '');
    });
}

function setPlaceholderOrFlagChanged(input, text) {
    (input.val() === '') ? input.val(text) : input.data('changed', true);
}

function setupPasswords(input) {
    var passwordPlaceholder = createPasswordPlaceholder(input);
    input.after(passwordPlaceholder);

    (input.val() === '') ? input.hide() : passwordPlaceholder.hide();

    $(input).blur(function(e) {
        if (input.val() !== '') return;
        input.hide();
        passwordPlaceholder.show();
    });

    $(passwordPlaceholder).focus(function(e) {
        input.show().focus();
        passwordPlaceholder.hide();
    });
}

function createPasswordPlaceholder(input) {
    return $('<input>').attr({
        placeholder: input.attr('placeholder'),
        value: input.attr('placeholder'),
        id: input.attr('id'),
        readonly: true
    }).addClass(input.attr('class'));
}

function clearPlaceholdersBeforeSubmit(form) {
    form.find(':input[placeholder]').each(function() {
        if ($(this).data('changed') === true) return;
        if ($(this).val() === $(this).attr('placeholder')) $(this).val('');
    });
}
})(jQuery);

Then you have to invoke the plugin in your php page or in another js simply by:

 $(function() {
    // Invoke the plugin
    $('input, textarea').placeholder();       
   });

Hope this helps!

It sounds like your javascript is breaking the native IE10 placeholder functionality.

To test this, and hopefully fix it, wrap the javascript you have written for placeholders in a conditional statement, so that it only applies to IE9 and below.

<!--[if lt IE 9]>
<script>
  document.createElement('header');
  document.createElement('nav');
</script>
<![endif]-->

Alternatively, there is a very nice jquery plugin by Mathias Bynens that is available for free and handles all of this for you: https://github.com/mathiasbynens/jquery-placeholder

Some CMSs already have a plugin built using this code. The Wordpress plugin is here: http://wordpress.org/plugins/html5-placeholder-polyfill/

i am not sure about placeHolder attribute for input support in ie10,but if u want a placeholder in ie u can do this throug jquery like this below..

if(navigator.appVersion.match(/MSIE [\d.]+/)){
    var placeholderText = 'Some Placeholder Text';
    $('#loginname').val(placeholderText);
    $('#loginname').blur(function(){
        $(this).val() == '' ? $(this).val(placeholderText) : false;
    });
    $('#loginname').focus(function(){
        $(this).val() == placeholderText ? $(this).val('') : false;
    });
}

u can do same for password too..

Have U tried somewhat like this using code...i believe should work...

$('#loginname').attr('placeholder', 'username');
$('#password').attr('placeholder', 'password');
