Add onClick attribute to login form textfield?

Posted by Fiasst onApril 26, 2007 at 5:31pm

Hello,

I'm trying to add onClick and onBlur attributes to my Login form input textfields. I have no idea how to achieve this but I found '#attributes' => array( shown in the below code. It's probably not the way to do it and I'd really appreciate some help!

Thanks.

function user_login_block() {
  $form = array(
    '#action' => url($_GET['q'], drupal_get_destination()),
    '#id' => 'user-login-form',
    '#base' => 'user_login',
  );
  $form['name'] = array('#type' => 'textfield',
    '#title' => t('Username'),
    '#maxlength' => USERNAME_MAX_LENGTH,
    '#size' => 15,
'#value' => t('Username'),
    '#required' => TRUE,
'#attributes' => array(
    'onblur' => 'clickclear(this, 'Username')',
    'onclick' => 'clickrecall(this, 'Username')'),
  );

Ah, Just as I posted this I found my way! BUT, by using " " in the code below, viewing the page source I get:
onblur="clickrecall(this, "Username")" onclick="clickclear(this, "Username")"

Question: How do you use quote marks with php when already inside quote marks? in Javascript I beleive you add a forward slash like: 'clickrecall(this, /'Username/';)'

Thanks!

The code so far:

function user_login_block() {
  $form = array(
    '#action' => url($_GET['q'], drupal_get_destination()),
    '#id' => 'user-login-form',
    '#base' => 'user_login',
  );
  $form['name'] = array('#type' => 'textfield',
    '#title' => t('Username'),
    '#maxlength' => USERNAME_MAX_LENGTH,
    '#size' => 15,
    '#required' => TRUE,
'#attributes' => array(
    'onblur' => 'clickrecall(this, "Username")',
    'onclick' => 'clickclear(this, "Username")'),
'#value' => t('Username'),
  );
  $form['pass'] = array('#type' => 'password',
    '#title' => t('Password'),
    '#maxlength' => 60,
    '#size' => 15,
'#attributes' => array(
    'onblur' => 'clickrecall(this, "Password")',
    'onclick' => 'clickclear(this, "Password")'),
'#value' => t('Password'),
    '#required' => TRUE,
  );

Use double quotes

Posted by drbutts onAugust 10, 2007 at 8:26pm

Just had this problem and figured it out.

Use 'onclick' => "clickclear(this, 'Username')"

Note the reversal where single quotes are double quotes, and vice versa.

Not able to set password default value

No solution?

Posted by ideveloper onJuly 27, 2007 at 12:19pm

Has anyone found a solution for that? I've got the same problem and I can't figure out how to solve it..

create a variable

Posted by BobbyG123 onOctober 26, 2007 at 1:00pm

A simple solution that worked for me, is to create a variable to hold the offending '' part of the js
e.g

////////////////////////////
//var to get around '' issue
$div1= "'div1'";
  'onclick' => 'showMe('.$div1.', this)'),

You could even put the whole js onclick string into the variable.

hook_form_alter or jquery

Posted by bboyjay onJuly 27, 2007 at 1:58pm

your 2 options are to either build a simple module that implements hook_form_alter and add it in:

http://api.drupal.org/api/HEAD/function/hook_form_alter

or if you're using drupal 5, do a jquery equivalent to what you want to do.

Alternate solution

Posted by anttix onNovember 27, 2007 at 2:58pm

I tried some of the solutions for adding javascript into the #attributes with no success. I tried an alternative solution by adding the javascript to #prefix like the following, but it didn't work either.

$form['test'] = array(
'#type' => 'button',
'#value' => t('Test'),
'#prefix' => '
function test() {
alert("test");
}
',
'#attributes' => array('onclick' => 'javascript: test();'),
);

This worked to an extent... It will display the javascript correctly without changing the quotes to html, but will not work for a redirect. The form gets re-render so if the data does not validate than the user is brought back to the form. If you don't want the user to leave the form without filling out the form fields than this is a acceptable solution. In order to get a redirect working I had to create a button outside of the form using the markup type.

$form['previous'] = array(
'#prefix' => '',
'#value' => '',
'#suffix' => '',
);

Not sure what the security implications are for this alternative so use at your own risk.

text module issue

Posted by kenorb onMay 22, 2009 at 4:32pm

If you using text module for that (CCK), check this issue:
#470260: #attributes are not properly rendered

Good, it works

Posted by javilete onOctober 27, 2009 at 7:34pm

Hi, I have been taking a look and searching some information about how to add events in a field of a form. Everything is done fine but I dont know how to add the function. For example, in the last post, where do you have the function "clickrecall()"?
Thanks a lot in advance.

any fix to this?

Posted by getstarted onJanuary 26, 2010 at 5:09am

I tried all the suggestions posted here, but none worked. Always rendering as &, etc., to the page. Thanks,

?

Posted by b.tomi onFebruary 27, 2010 at 4:42pm

    '#default_value' => t('Username'),
    '#attributes' => array(
        'onblur' => 'this.value="Username"',
        'onclick' => 'this.value=""'),

I arrived at a similar solution when working on a search block form:

    $form['search_block_form']['#attributes'] = array(
      'onfocus' => "if (this.value == 'Enter Search') {this.value = '';}",
      'onblur' => "if (this.value == '') {this.value = 'Enter Search';}"
    );
