Read only field in SharePoint EditForm.aspx

Using JavaScript

First find out the tag corresponding to the input field which would like to set as read only

For this open up the editform.aspx page right click it and select view source

Say this is the tag of the input field

<input name=”TextField” type=”text” value=”Approved” maxlength=”255″ id=”4_ctl00_ctl00_TextField” title=”Status of Idea” class=”ms-long” />

Now open your editform.aspx page in SharePoint designer and add the following script to it

<script type=”text/javascript”>

function SetReadOnly()

{

// find all the elements with tag Name as INPUT

var elements=document.body.getElementsByTagName(“INPUT”);

// loop through all the elements till we find an element with type text and title as name of our field

for (index=0; index < elements.length;++index)

{

if(elements[index].type==“text”)

{

if(elements[index].title==“Status of Idea”)

{

elements[index].readOnly=true;

}

}

}

}

_spBodyOnLoadFunctionNames.push(“SetReadOnly()”);

</script>

Or

<script type=”text/javascript”>

function SetReadOnly()

{

var elements=document.getElementById(’4_ctl00_ctl00_TextField’);

elements.readOnly=true;

}

_spBodyOnLoadFunctionNames.push(“SetReadOnly()”);

</script>

Or using event handler as mentioned over here

Or

And to hide button say OK button than

function SetHidden()
{
alert(‘Hi’);
var x=document.getElementsByTagName(“input”);
for (var i=0;i<x.length;i++)
{
if (x.item(i).type==”button”&&x.item(i).value==”OK”)
{
x.item(i).style.display = “none”
};
}
}
_spBodyOnLoadFunctionNames.push(“SetHidden()”);

Bye…
