input placeholders for internet explorer


input placeholders for internet explorer  using -'javascript,html,internet-explorer,placeholder'

HTML5 introduced the placeholder attribute on input elements, which allows to display a greyed-out default text.

Sadly the Internet Explorer, including IE 9 does not support it.

There already are some placeholder simulator scripts out there. They typically work by putting the default-text into the input field, give it a grey color and remove it again as soon as you focus the input field.

The drawback of this approach is that the placeholder text is in the input field. Thus:


scripts can't easily check whether an input field is empty
server side processing must check against the default value, in order to not insert the placeholder into the database.


I would like to have a solution, where the placeholder text isn't in the input itself.

In looking at the "Web Forms : input placeholder" section of HTML5 Cross Browser Polyfills, one I saw was jQuery-html5-placeholder.

I tried the demo out with IE9, and it looks like it wraps your with a span and overlays a label with the placeholder text.


There are also other shims there, but I didn't look at them all. One of them, Placeholders.js, advertises itself as "No dependencies (so no need to include jQuery, unlike most placeholder polyfill scripts)."

Edit: For those more interested in "how" that "what", How to create an advanced HTML5 placeholder polyfill which walks through the process of creating a jQuery plugin that does this.

Also, see keep placeholder on focus in IE10 for comments on how placeholder text disappears on focus with IE10, which differs from Firefox and Chrome. Not sure if there is a solution for this problem.

With a jQuery implementation you can EASILY remove the default values when it is time to submit. Below is an example:

$('#submit').click(function(){
   var text = this.attr('placeholder');
   var inputvalue = this.val();  // you need to collect this anyways
   if (text === inputvalue) inputvalue = "";

   // $.ajax(...  // do your ajax thing here

});

I know that you are looking for an overlay, but you might prefer the ease of this route (now knowing what I wrote above). If so, then I wrote this for my own projects and it works really nice (requires jQuery) and takes just a couple minutes to implement for your entire site. It offers grey text at first, light grey when in focus, and black when typing. It also offers the placeholder text whenever the input field is empty.

First set up your form and include your placeholder attributes on the input tags.


Just copy this code and save it as placeholder.js.

(function( $ ){

   $.fn.placeHolder = function() {  
      var input = this;
      var text = input.attr('placeholder');  // make sure you have your placeholder attributes completed for each input field
      if (text) input.val(text).css({ color:'grey' });
      input.focus(function(){  
         if (input.val() === text) input.css({ color:'lightGrey' }).selectRange(0,0).one('keydown', function(){     
            input.val("").css({ color:'black' });  
         });
      });
      input.blur(function(){ 
         if (input.val() == "" || input.val() === text) input.val(text).css({ color:'grey' }); 
      }); 
      input.keyup(function(){ 
        if (input.val() == "") input.val(text).css({ color:'lightGrey' }).selectRange(0,0).one('keydown', function(){
            input.val("").css({ color:'black' });
        });               
      });
      input.mouseup(function(){
        if (input.val() === text) input.selectRange(0,0); 
      });   
   };

   $.fn.selectRange = function(start, end) {
      return this.each(function() {
        if (this.setSelectionRange) { this.setSelectionRange(start, end);
        } else if (this.createTextRange) {
            var range = this.createTextRange();
            range.collapse(true); 
            range.moveEnd('character', end); 
            range.moveStart('character', start); 
            range.select(); 
        }
      });
   };

})( jQuery );

To use on just one input

$('#myinput').placeHolder();  // just one

This is how I recommend you implement it on all input fields on your site when the browser does not support HTML5 placeholder attributes:

var placeholder = 'placeholder' in document.createElement('input');  
if (!placeholder) {      
  $.getScript("../js/placeholder.js", function() {   
      $(":input").each(function(){   // this will work for all input fields
        $(this).placeHolder();
      });
  });
}

Best one in my experience is https://github.com/mathiasbynens/jquery-placeholder (recommended by html5please.com). http://afarkas.github.com/webshim/demos/index.html also has a good solution among its much more extensive library of polyfills.

After trying some suggestions and seeing issues in IE here is the one that works:

https://github.com/parndt/jquery-html5-placeholder-shim/

What I have liked - you just include the js file. No need to initiate it or anything.

  • Works only for IE9+

The following solution binds to input text elements with the placeholder attribute. It emulates a placeholder behaviour just for IE and clears the input's value field on submit if it is not changed.

Add this script and IE would seem to support HTML5 placeholders.

  $(function() {
  //Run this script only for IE
  if (navigator.appName === "Microsoft Internet Explorer") {
    $("input[type=text]").each(function() {
      var p;
     // Run this script only for input field with placeholder attribute
      if (p = $(this).attr('placeholder')) {
      // Input field's value attribute gets the placeholder value.
        $(this).val(p);
        $(this).css('color', 'gray');
        // On selecting the field, if value is the same as placeholder, it should become blank
        $(this).focus(function() {
          if (p === $(this).val()) {
            return $(this).val('');
          }
        });
         // On exiting field, if value is blank, it should be assigned the value of placeholder
        $(this).blur(function() {
          if ($(this).val() === '') {
            return $(this).val(p);
          }
        });
      }
    });
    $("input[type=password]").each(function() {
      var e_id, p;
      if (p = $(this).attr('placeholder')) {
        e_id = $(this).attr('id');
        // change input type so that the text is displayed
        document.getElementById(e_id).type = 'text';
        $(this).val(p);
        $(this).focus(function() {
          // change input type so that password is not displayed
          document.getElementById(e_id).type = 'password';
          if (p === $(this).val()) {
            return $(this).val('');
          }
        });
        $(this).blur(function() {
          if ($(this).val() === '') {
            document.getElementById(e_id).type = 'text';
            $(this).val(p);
          }
        });
      }
    });
    $('form').submit(function() {
      //Interrupt submission to blank out input fields with placeholder values
      $("input[type=text]").each(function() {
        if ($(this).val() === $(this).attr('placeholder')) {
          $(this).val('');
        }
      });
     $("input[type=password]").each(function() {
        if ($(this).val() === $(this).attr('placeholder')) {
           $(this).val('');
        }
      });
    });
  }
});

I suggest you a simple function :

function bindInOut(element,value)
{
    element.focus(function()
    {
        if(element.val() == value) element.val('');         
    }).
    blur(function()
    {
        if(element.val() == '') element.val(value);
    });

    element.blur();
}

And to use it, call it in this way :

bindInOut($('#input'),'Here your value :)');

You can use :

var placeholder = 'search  here';

$('#search').focus(function(){
    if ($.trim($(this).val()) ===  placeholder){
        this.value ='';
    }
}).blur(function(){
    if ($.trim($(this).val()) ===  ''){
        this.value = placeholder;
    }
}).val(placeholder);

I came up with a simple placeholder JQuery script that allows a custom color and uses a different behavior of clearing inputs when focused. It replaces the default placeholder in Firefox and Chrome and adds support for IE8.

// placeholder script IE8, Chrome, Firefox
// usage: 
$(function () { 
    var textColor = '#777777'; //custom color

    $('[placeholder]').each(function() {
        (this).attr('tooltip', $(this).attr('placeholder')); //buffer

        if ($(this).val() === '' || $(this).val() === $(this).attr('placeholder')) {
            $(this).css('color', textColor).css('font-style','italic');
            $(this).val($(this).attr('placeholder')); //IE8 compatibility
        }

        $(this).attr('placeholder',''); //disable default behavior

        $(this).on('focus', function() {
            if ($(this).val() === $(this).attr('tooltip')) {
                $(this).val('');
            }
        });

        $(this).on('keydown', function() {
            $(this).css('font-style','normal').css('color','#000');
        });

        $(this).on('blur', function() {
            if ($(this).val()  === '') {
                $(this).val($(this).attr('tooltip')).css('color', textColor).css('font-style','italic');
            }
        });
    });
});

Placeholdr is a super-lightweight drop-in placeholder jQuery polyfill that I wrote. It's less than 1 KB minified.

I made sure that this library addresses both of your concerns:

  1. Placeholdr extends the jQuery $.fn.val() function to prevent unexpected return values when text is present in input fields as a result of Placeholdr. So if you stick with the jQuery API for accessing your fields' values, you won't need to change a thing.

  2. Placeholdr listens for form submits, and it removes the placeholder text from fields so that the server simply sees an empty value.

Again, my goal with Placeholdr is to provide a simple drop-in solution to the placeholder issue. Let me know on Github if there's anything else you'd be interested in having Placeholdr support.

i use jquery.placeholderlabels. It's based on this and can be demoed here.

works in ie7, ie8, ie9.

behavior mimics current firefox and chrome behavior - where the the "placeholder" text remains visible on focus and only disappears once something is typed in the field.

I created my own jQuery plugin after becoming frustrated that the existing shims would hide the placeholder on focus, which creates an inferior user experience and also does not match how Firefox, Chrome and Safari handle it. This is especially the case if you want an input to be focused when a page or popup first loads, while still showing the placeholder until text is entered.

Placeholders.js is the best placeholder polyfill I've seen, is lightweight, doesn't depend on JQuery, covers other older browsers (not just IE), and has options for hide-on-input and run-once placeholders.
