Can this script work in SharePoint 2010

Any help you can give is greatly appreciated!

// To “pre uncheck” checkboxes, add names to this array
var arrOfPreHiddenColumns = ['Customer name',Customer number','Sales Manager','Country','City',Core Segment','Subsegment','Technology','Specific Techn','End Use','Est Close Yr','Est Close Qtr','Opp Status','Sales Status','Est Current Year €K','Est Annual €K','Est Annual Volume','Sales Comment','Competitor','Incumbent','WonLoss','Won/Loss Reason','LWR Number','EMEA Region','Carry over','Created By','Modified By'];

// Pull columns to “pre uncheck” from the query string parameter “ColumnsToHide”
var qStrPAram = getQueryParameters();
var colFromQueryString = qStrPAram.ColumnsToHide;
if(colFromQueryString!=undefined){
arrOfPreHiddenColumns = arrOfPreHiddenColumns.concat(colFromQueryString.split(’,'));
}
init_Checkboxes(arrOfPreHiddenColumns);

My CEWP script below:

// To "pre uncheck" checkboxes, add names to this array
	var arrOfPreHiddenColumns = ['Customer name',Customer number','Sales Manager','Country','City',Core Segment','Subsegment','Technology','Specific Techn','End Use','Est Close Yr','Est Close Qtr','Opp Status','Sales Status','Est Current Year €K','Est Annual €K','Est Annual Volume','Sales Comment','Competitor','Incumbent','WonLoss','Won/Loss Reason','LWR Number','EMEA Region','Carry over','Created By','Modified By'];

// Pull columns to "pre uncheck" from the query string parameter "ColumnsToHide"
	var qStrPAram = getQueryParameters();
	var colFromQueryString = qStrPAram.ColumnsToHide;
	if(colFromQueryString!=undefined){
		arrOfPreHiddenColumns = arrOfPreHiddenColumns.concat(colFromQueryString.split(','));
	}
	init_Checkboxes(arrOfPreHiddenColumns);

However I had a slight problem when dropping multiple list views on a page. I found that whilst the content of the columns were hidden in every list view the column header was only hidden on the first list view.

I got round this by writing my own code to recursively look through and hide each of the column headers.

The issue was with function hidecolumn it hides the column header and then all content. But whilst it finds each content cell (and by that rule hides every instance in every web part) it only does the first column header.

I have only started hacking with Jquery and javascript over the past week or so, so it’s not very elegant but I got round it by doing this…. (I had to hard code the column header name)

$(".ms-viewheadertr >*[class^='ms-v']").each(function(){
    var thToToggle = $(this).find("[name*='Profiles']");
   thToToggle.hide();

    });

I have found that if you try and call a CEWP script that is not on the site (i.e. using the “Content Link” in the CEWP) the location where the script resides MUST have anonymous access turned on:

http://office.microsoft.com/en-us/sharepointserver/HA100240461033.aspx

“If the Content Link property links to a file that is located outside the site and the site does not have anonymous user access enabled, you cannot access the file. For assistance, contact your site administrator.”

I believe even if you are in the same collection, you must have it turned on. So if you are calling, using “Content Link”, a script that in on the top level, you may need to turn on anonymous access to that folder.

Sorry if this is not your situation. I am able to load the CEWP content in via source editor, and point to the jQuery and Toggle scripts using fully qualified URLs of an offsite “resource center” with no problems.

The Script Library is in a top level site, and the CEWP code points to that location. I have tried this with absolute and relative references, makes no difference.

Creates a special page for the list, placed the CEWP below or above the list. Makes no difference.

Made sure that Full Toolbar was on (per your example).

Nothing shows above the Toolbar.

Any thoughts about this? Potential mistakes?
