Hide JS element without div or class
Question
I am trying to hide the toolbar of a SSRS report.
There is a specific reason why I need to use JS( The report will be included in the CRM 2011 Dashboard, and I wanted to remove the toolbar from the Report. Since the report parameters did not work, I imported Report Control solution and I am editing the viewer, which uses JS ). The viewer is a Html page that embeds the Report as an IFrame. The generated Html code is:
<table id="reportViewer_fixedTable" cellspacing="0" cellpadding="0" style="table-layout:fixed;width:100%;height:100%;">
<tbody>
<tr style="background-color:#C4DDFF;"> … </tr>
<tr id="ParametersRowreportViewer" style="display:none;"> … </tr>
<tr style="height:6px;font-size:2pt;display:none;"> … </tr>
<tr>
The toolbar is in the 4th tr, and selecting it directly and trying to hide it did not work.
navCorrectorDiv = report.contentWindow.document.getElementById('reportViewer_Toolbar');
if (navCorrectorDiv != null) {
navCorrectorDiv.style.display = "none";
}
I should select the table reportViewer_fixedTable, that I can do, then select the tbody element and then the fourth tr. Is there a way to do it? Possibily without jQuery.

Case: No Iframe
Select the element
As jQuery selector:
var selected;
selected = jQuery('#reportViewer_fixedTable');
…
selected = jQuery('#reportViewer_fixedTable tbody');
…
selected = jQuery('#reportViewer_fixedTable tr:nth-child(4)');
Hide selected with:
selected.css('display', 'none');
or with modern browsers without jQuery:
var selected;
selected = document.querySelector('#reportViewer_fixedTable');
…
selected = document.querySelector('#reportViewer_fixedTable tbody');
…
selected = document.querySelector('#reportViewer_fixedTable tr:nth-child(4)');
And hide:
selected.style.display = 'none';
Case: Content in Iframe
The iframe can be problematic, because it might be sandboxed or the content might come from a different domain. This can lead into a XSS-violation which, in your case, might be unfixable.
Anyway, here we go:
//Select the first iframe (which might not be the right one in your case);
var elem = document.querySelector('iframe');
//And put it's body in a variable. We use the querySelector from the body
//of the iframe.
var ibody = elem.contentWindow.document.body;
var table = ibody.querySelector('#reportViewer_fixedTable');
var tbody = ibody.querySelector('#reportViewer_fixedTable tbody');
var fourthtr = ibody.querySelector('#reportViewer_fixedTable tr:nth-child(4)');
table.style.display = 'none';
tbody.style.display = 'none';
fourthtr.style.display = 'none';

I guess you can do it by trying to find the nth Chid
Consider this approach :
HTML :
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<meta charset=utf-8 />
<title>JS Bin</title>
</head>
<body>
<table id="reportViewer_fixedTable" cellspacing="0" cellpadding="0" style="table-layout:fixed;width:100%;height:100%;">
<tbody>
<tr style="background-color:#C4DDFF;"> <td>1</td> </tr>
<tr id="ParametersRowreportViewer" style="display:none;"><td>2</td> </tr>
<tr style="height:6px;font-size:2pt;display:none;"> <td>3</td> </tr>
<tr><td>FourthTR</td></tr>
</tbody>
</table>
</body>
</html>
JS:
$(function(){
console.log( $('#reportViewer_fixedTable tbody tr:nth-child(4) td:nth-child(1)').text());
$('#reportViewer_fixedTable tbody tr:nth-child(4) td:nth-child(1)').addClass('FourthTR');
$('.FourthTR').hide();
});
So , what we are trying to do is that, we are grabbing the 4th tr of the table and then we are grabbing the 1st child of the 4th tr. Once that is done, we are , on the fly, gonna add a class to it say FourthTR and then hide the class using jQuery.hide() . Voila, you are done.
See the working example here: http://jsbin.com/ACam/1/edit . As always, remember to run with js .

I don't think you need to use JavaScript for this
If you have access to ReportControl solution and server-side code of ReportViewer.aspx.cs, you can set property
reportViewer.ShowToolBar = false
in that code.
Alternatively, if you have access to and can modify viewer page markup (ReportViewer.aspx), you can set it declaratively: by adding ShowToolBar="false" to ReportViewer control declaration:
<rsweb:ReportViewer ID="reportViewer" runat="server" ... ShowToolBar="false">
</rsweb:ReportViewer>
If this is not an option, you can amend URL you're passing to IFrame hosting ReportViewer, by adding rc:Toolbar=false parameter
http://localhost/ReportServer/Pages/ReportViewer.aspx?%2fMyReport%2fBEA&rs:Command=Render&rc:Toolbar=false
