Microsoft enforces read/write-once-rule for the type-attribute of <input>-elements. See  http://docs.jquery.com/Core#.24.28_html_.29

Attempting to do this now throws an exception in all browsers. Fixed in SVN rev [3096].

There is a solution for this kind of problem described at  http://www.dynamicsitesolutions.com/javascript/dynamically-changing-input-type/

It creates a clone of element with same attributes except for type. That might help because changing the type of input element via jQuery is a really sweet feature.

Unfortunately, this particular hack is not feasible within jQuery (you also have to worry about issues like copying styles and events of the object) - since old jQuery matched sets may reference old versions of the input element, for example:

  var fields = $("input")
  $("input:first").attr("type", "hidden");
  fields[0].type == "text"
}}

Until there's a way around that, we're going to have to be content with the current solution.

Not very smart making this throw an exception in all browsers. I was just about to file a bug on this.

It's possible outside IE, and Applesearch uses it to change the input type in Safari to 'search'. Guess I'll have to throw out the original element and replace it with a new one. Please just keep it in mind before making such a change.

In my WordPress plugin I've used the following method of changing the type on the fly (cross-browser), maybe it may help someone or incorporated into the jQuery itself. This example alters type="password" to type="text":

var e = $(':password')[0]; e.replaceWith($(e.wrap('<label></label>').parent('label').html().replace(/type=\"?password\"?/, 'type="text"')));

Sorry, doesn't seem to work as it should. For some reason jQuery fails to construct proper input element. Had to rewrite constructor in pure javascript.

Not a good way of doing this.

Hi

I have an input type of text.

<input id="iPassword" value="Password" type="text"/>

in jQuery I want to change the type="password" when someone focus on it.

I tried this

$('#iPassword').focus(function(){

$(this).attr("type","password");

});

but it doesn't work.

any Ideas??

Please do not reopen tickets to ask for programming help, just ask the question in the forums.

This issue is fixed as well as it can be considering IE's only-set-it-once rule for the type attribute of input elements.
