Disable field

[blitz2190]

I have a field that i want to be disabled on loading the module in sugar 5.2.0h. to test i add this to the opportunities module:

 1 => 
        array (
          'label' => '10',
          'field' => '30',
        ),
      ),
          //this part here
      'includes'=> array(  
        array('file'=>'custom/modules/Opportunities/disable.js'),
     ),
         ... 
  

and in disable.js

function disable_field()
{
getElementsByName('amount')[0].disabled=true;
} 

if (window.addEventListener)
window.addEventListener("load", disable_field, false);
else if (window.attachEvent)
window.attachEvent("onload", disable_field)
else
window.onload=disable_field

but when I try to create a new record the amount field is still enabled

i also tried putting in index.php, editviewdefs.php and Opportunityvardefs.php

 echo '<input type="hidden" onLoad="getElementsByName(\'amount\')[0].disabled=true">'; 
  

on a side note adding a button with the above code and change to onclick works when you click the button

 echo '<button onClick="getElementsByName(\'amount\')[0].disabled=true">Click</button>'; 
  

a simple question is why doesn't this work

 array (
            'name' => 'sales_stage',
            'displayParams' => 
            array (
              'required' => true,
              'javascript' => 'onload="getElementsByName(\'sales_stage\')[0].disabled=true"',
            ),
            'label' => 'LBL_SALES_STAGE',
          ), 
  

but i change to onclick it works when i click it, so why doesn't the onload function work in 5.2.0h

can anyone tell me why this isn't working

There may be a simpler way to disable a field ...

goto Admin>Studio>Opportunities ... editview & detailview

Drag and drop the field you don't want

because i need the field later. when i figure this out it will be going in a custom module that will only enable the field when a certain user is editing it, which i will be able to do with enhanced studio the only problem is enhanced studio demo only works when editing not creating a record. so my question is when do i put the onload function where it will be called by the module

also why does this work

 array (
            'name' => 'sales_stage',
            'displayParams' => 
            array (
              'required' => true,
              'javascript' => 'onclick="this.disabled=true;"', 
  

but this doesn't

 array (
            'name' => 'sales_stage',
            'displayParams' => 
            array (
              'required' => true,
              'javascript' => 'onload="this.disabled=true;"',

does any one know how to disable fields with javascript

[blitz2190]

i finally figured this out
in custom/modules/module_name add the javascript in in the $viewdefs

 $viewdefs ['module_name'] = 
array (
  'EditView' => 
  array (
    'templateMeta' => 
    array (
      'form' => 
      array (
        'enctype' => 'multipart/form-data',
        'headerTpl' => 'modules/moudule_name/tpls/EditViewHeader.tpl',
      ),
      'maxColumns' => '2',
      'widths' => 
      array (
        0 => 
        array (
          'label' => '10',
          'field' => '30',
        ),
        1 => 
        array (
          'label' => '10',
          'field' => '30',
        ),
      ),
      //add this code
      'javascript' => '<script>
window.onload=function() 
{literal} { {/literal}
      document.getElementById(\'field_name\').disabled=true;
{literal} } {/literal}
  </script>',
