在IE8中输入类型密码的jQuery输入占位符

Question

I am using jQuery instead of HTML5 placeholder attribute

<input type="text" name="email" value="Email" onfocus="if (this.value == 'Email') { this.value = ''; }" onblur="if (this.value == '') { this.value = 'Email'; }" onclick="if (this.value == 'Email') { this.value = ''; }"  />

this is working fine for type="text" but for type="password" it show only *

How i will use placeholder for password field? Need out in IE8

Advance thanks for answers...

Answer 1

I create a normal input, and on focus switch it to a password field, and if the value is empty on blur , then switch it back to a normal input, else leave it as the password field.

Here is a working JSFiddle: http://jsfiddle.net/q8ajJ/

The HTML

<!-- Style = display none for people who dont have javascript -->
<input type="text" name="fake_pass" id="fake_pass" value="Enter Password:" style="display:none"/>
<input type="password" name="real_pass" id="real_pass"/>​

The Javascript (jQuery)

// On DOM ready, hide the real password
$('#real_pass').hide();

// Show the fake pass (because JS is enabled)
$('#fake_pass').show();

// On focus of the fake password field
$('#fake_pass').focus(function(){
    $(this).hide(); //  hide the fake password input text
    $('#real_pass').show().focus(); // and show the real password input password
});

// On blur of the real pass
$('#real_pass').blur(function(){
    if($(this).val() == ""){ // if the value is empty, 
        $(this).hide(); // hide the real password field
        $('#fake_pass').show(); // show the fake password
    }
    // otherwise, a password has been entered,
    // so do nothing (leave the real password showing)
});

Here is another dirty hack - you can create label with position: absolute and show/hide it with JS on focus and blur.

As far as I know, it works in any browser. Moreover, it is more simple to validate form submitting.

HTML

<div class="wrapper">
    <input class="withPlaceholder" type="password" id="pass" />
    <label class="placeholder" for="pass">Password</label>
</div>
<br />
<div class="wrapper">
    <input class="withPlaceholder" type="password" id="pass2" />
    <label class="placeholder" for="pass2">Password2</label>
</div>

CSS

div.wrapper {position: relative}
label.placeholder {position: absolute; color: #CCC; left: 2px; top: 0} 

JS

$("input.withPlaceholder").on({
    focus: function() {
        $("label[for=" + $(this).prop("id") + "]").hide();
    },
    blur: function() {
        if ($(this).val().length == 0) {
            $("label[for=" + $(this).prop("id") + "]").show();
        }
    }
});

Based on JustAnil's answer, and looking for a way to avoid having to manually add each corresponding for every password fields, I came up with this adaptation of JustAnil's solution:

function ManagePasswords(root) {
    root.find('input[type=password][placeholder]').each(function (index, current) {
        var $current = $(current),
            $fake = $current.clone().attr('type', 'text');

        $fake.val($fake.attr('placeholder'));

        $fake.insertBefore($current);
        $current.hide();

        $fake.focusin(function () {
            $(this).hide();
            $(this).next().show().focus();
        });

        $current.blur(function () {
            if ($(this).val() == '') {
                $(this).hide();
                $(this).prev().show();
            }
        });
    });
}

Then all you have to do is call

ManagePasswords($('#rootElement'));

Hope this helps!

Adding another input element for the placeholder may create trouble during form validation and submission. I solved this in a different way.

The HTML

<form id="test">
    <input type="text" id="name" name="name" placeholder="Name"  />
    <input type="password" id="password" name="password" placeholder="Password" />
</form>

jQuery Function

function placeholder(form) {
    form.wrapInner('<ul style="list-style: none; list-style-type:none; padding:0; margin: 0;">');
    form.find('input[placeholder]').each(function (index, current) {
        $(current).css('padding', 0).wrap('<li style="position: relative; list-style: none; list-style-type:none; padding:0; margin: 0;">');            
        var height = $(current).parent('li').height();
        var $current = $(current),
            $placeholder = $('<div class="placeholder">'+$current.attr('placeholder')+'</div>');
        $placeholder.css({'color': '#AAA', 'position':'absolute', 'top': 0, 'left': 0, 'line-height': height+'px', 'margin': '0 0 0 5px', 'border': '0 none', 'outline': '0 none', 'padding': 0});
        $placeholder.insertAfter($current);
        $current.removeAttr('placeholder');
        $placeholder.click(function(){
            $current.focus()
        });
        $current.keypress(function(){
            if($(this).val().length >= 0) {
                $placeholder.hide();
            } 
        });
        $current.blur(function(){
            if($(this).val().length == 0) {
                $placeholder.show();
            } else {
                $placeholder.hide();
            }
        });                 
    });         
}

Now just call function for your form.

placeholder($("#test"));

This will work for all type of input field with placeholder including type="password" tested in IE8, IE9, IE10, Google Chrome, FireFox, Safari and Opera.

Use this code, jQuery will do the rest...

html tag replace

<!--[if IE 8]><html class="ie8"><![endif]-->
<!--[if gt IE 8]><html><![endif]-->

jQuery goodness...

$(document).ready(function(){

$('.ie8 [placeholder][type="password"]').each(function(){
        $(this).wrap('<div style="position: relative;"></div>');
        $('<span style=" position: absolute;top: 5px;left:14px;" class="ie8Lbls">'+$(this).attr('placeholder')+'</span>').insertAfter($(this));
        $(this).attr('placeholder','');
        if($(this).val() == "") {$(this).parent().find('.ie8Lbls').show();}
    }).on('focus',function(){
        $(this).parent().find('.ie8Lbls').hide();
    }).on('blur',function(){
        if($(this).val() == "") {$(this).parent().find('.ie8Lbls').show();}
    });
    $(document).on('click','.ie8Lbls',function(){
        $(this).parent().find('input').focus();
    });

});

style to change the looks of the new placeholder

<style>
.ie8Lbls {
    font-size:10px;
}
</style>
