Client-script: Iterate through the variable_pool?

[MattGlew]

Is it possible, client-side, to loop through all of the form variables (variable_pool) on a requested item form, with a view to making them read-only?

My approach in the past has always been to create an sc_req_item OnLoad client-script (one for each CatItem) and type out each variable individually (well, export vars to Excel, re-format into code & copy back), which is fine, but a bit long in the tooth & can come back to bite you in the future if a new variable is added to the CatItem and you forget to add it to the client script.

It would be a much neater solution if I could simply loop through the variables! I've only been able to find server-side code on the wiki, which isn't a lot of help in this case. I suppose an Ajax call could retrieve the variable_pool array (assuming it's an array) and I could then enumerate that, but there could be hundreds of variables on the page, so that approach would be extremely inefficient.

I've also had a look at the rendered HTML of the page and there's nothing obvious that identifies variable-related widgets / elements, so another dead-end.

Any ideas?

Take a look at the code in this post - Saving a record without populating all mandatory variables

It goes through each variable and sets the mandatory attribute to false. You should be able to use it for switching them to read-only. Remember though, mandatory fields cannot be set read-only.

Thanks Jim, that works a treat! I don't have time to regression test existing ReqItems (shame), so I'll add an if statement to the following code to ensure it only runs for requests I create from now on:

function onLoad() {
   try {
      var allVariables = document.getElementById('variable_map').getElementsByTagName('item');
      for(var i = 0; i < allVariables.length; i++){
         var item = allVariables<i>;
         g_form.setReadOnly('variables.' + item.getAttribute('qname').toString(),true);
      }
   } catch(err) {}
}

I was about to write this exact script for my instance.
Thanks for saving me the time! 🙂

Where can I get a list of the variable attributes that are available?
