The SharePoint Hillbilly Fewer Big Words... More Pretty Pictures...

Okay… this will be my shortest blog post EVER. Very little rambling.. I promise, and I’m sure this has been blogged more than once, so I apologize for adding to the noise, but like I always say, I blog for myself so I have a global bookmark. Smile

So,let’s say you have a field on a SharePoint Form and you want to make it read only. You COULD just open it up in SPD and easily make it read only, but some people are purists and don’t like use SPD or modify the default new/edit/disp forms. Put me in the latter camp, I try to avoid modifying these forms and it seemed like such a simple task that I didn’t want to create a new un-ghosted form.  So.. how do you do it?

It’s only one line of jQuery. All you need to do is find the id for your input field and capture the keypress on it so that it cannot be modified (you should probably capture clicks for dropdowns/checkboxes/etc. but I didn’t need to). 

Anyway, here’s the entire script:

<script src="jquery.min.js" type="text/javascript"></script>

<script type="text/javascript">

jQuery(document).ready(function($){

     //capture keypress on our read only field and return false
     $('#idOfInputField').keypress(function() {
            return false;
     });

})

</script> 

 

You can find the ID of your input field by viewing the source, this ID stays consistent as long as you don’t muck with the list or form in the wrong way.  Please note, you CANNOT disable the input field as an alternative to capturing the keypress. If you do this and save the form, any data in the disabled fields will be wiped out.

There are probably a dozen ways to make a field read-only and if all you are using jQuery for is to make a field read-only, then you might want to question your use of adding the overhead (although it’s really not that much).

Hey.. it’s another tool for your tool belt.

Where do I put the script if not in the Add or Edit form?
