JavaScript: Disabling text box in the report column cell
HelloAndi (ATD) helped with formatting of columns in the report, their coloration depending on a value. See:
JavaScript - referring to the value of the report column
Now, I want to add a feature:
If the value is "1" then turn off the text box in the column next, otherwise no. The function is:
function hilite(f1)
{
var h = document.getElementById(f1);
var t = h.parentNode;
while (t.tagName != 'TABLE')
{
t = t.parentNode;
}
var rows = t.rows;
var k;
var i;
var j;
var c;
var headers = t.getElementsByTagName("TH");
// var textarea = t.getElementsByTagName("textarea");
for (k = 0; k < headers.length; k++)
{
if (headers[k].id == f1)
{
c = k;
}
}
for (k = 1; k < rows.length; k++)
{
i = rows[k].cells[c];
j = rows[k].cells[c+1];
if (i.innerHTML == '2')
{
i.style.backgroundColor = 'yellow';
i.style.color = 'white';
i.style.fontWeight = 'bold';
i.style.fontSize = '18px';
}
if (i.innerHTML == '1')
{
i.style.backgroundColor = 'red';
i.style.color = 'white';
i.style.fontWeight = 'bold';
i.style.fontSize = '18px';
// j.style.backgroundColor = 'green'; // testing purpose; colors background green but not textarea
j.style.visibility = 'hidden'; // works fine but ugly
// j.disabled = 'true'; // nothing happens
// j.firstChild.disabled = 'true'; // does not work
// j.textarea.disabled = 'true'; // does not work
}
}
}
See the object of 'j': I can do the whole cells disappear, but it's ugly. It examines with firebug I thought I should use sth. such as firstChild or textarea, but it does not work. I find always pretty hard to manipulate tables in Apex...Could someone help with this?
Thank you very much
Roger
Hi Roger,
«"" You're sort of almost here!»»»
The next cell to the right of the one that that you are testing contains a TEXTAREA object. Your variable j accesses it using something like:
j = rows[k].cells[c+1].getElementsByTagName("TEXTAREA")[0];
The problem with the help of the method of visibility you have used will disappear while you applied to the entire purpose of TD, so all the borders will go - this application to the new j allows to hide the textarea rather object only.

Execution of SQL queries based on user input in the text box on the page of the APEX
Hello
I am new to develop in the APEX, and I encountered a problem...
It is even possible to do such a thing: use the text box to enter a SQL query and then run it on my schema and display the results in the report item? And if the answer is Yes, can someone give me advice on how to do this?
Thanks in advance.In my example, the text is from a file in a text box. The report source is a function returning the SQL query:
DECLARE v_query VARCHAR2 (4000); BEGIN v_query := :p91_sql_query; RETURN v_query; END;

Why can't put 2 text boxes on the same page?
I am trying to put 2 text boxes on the same page, but the 2nd box is still empty. However, if I move the 2nd box on the next page, or even on a previous page, the text block appears suddenly.
Why can't put 2 text boxes on the same page?
The little thing at the end of this first page must be a page break. Which is just what its supposed to change it to a Frame break or break column if you want to have the text to jump to the next available section.

What region in the report column HTML link?
Dear gurus of the Apex,
OK, I'll go straight to my question. I have a page to download file with region (conditional) report that comes after the file download process. According to the report that I have a column to remove the file downloaded (column has an image link, the target application, the name of the option: P2_DELETE_ID value: #DOC_ID #). Basically the report picks up just downloaded file ID and allows me to delete the file by having Hiden point Page (P2_DELETE_ID) and before the process of header:BEGIN
condition: Expression 1 value is not Null, and the value of the Expression 1:
REMOVE FROM EBA_ASSET_ORDER_TEMP_DOCS
WHERE annual =: P2_DELETE_ID;
END;P2_DELETE_ID
I and another conditional region (which is HTML) he comes after the file download process as well. The Source region is:
& lt; div id = "FinalMessage" > & lt; / div >
where id = "FinalMessage" - is the JS success/error message
& lt; br / >
& lt; div > & lt; a href = "javascript:confirmFileDelete(htmldb_delete_message,'f?p=&APP_ID.:2:&SESSION.:REMOVE_ID:::P2_DELETE_ID:#DOC_ID#')"; > & lt; "img > src="/i/delete.gif "style =" position: relative; " Top: 1px; ' / > delete the downloaded file & lt; /a >
& lt; / div >
and... href = "javascript:confirmFileDelete--is my real question. So I try to hide my region to report and show only my region HTML where I will be able to this (... href...) link delete file from my table. I am able to dele file using report link colum but my... href... link dosnt want to delete my file, doen't even want to pick up the ID of file. Is there a way where I can link my... href... link to pull the report column?
Thank youNP - now access, so I will have a look

IPhone 6plus - text box to the lock screen
Recently, I noticed that my lock screen got a new text box to enter my security PIN. I also see an OK button next to the text box to the lock screen that I did not see after the last update of OS. I did no upgrade of the OS recently and the current version is to 9.3.1 (13E238) (model: MGA82HN / A).
Is this something normal? I remember that this text box came after I tried to install Citrix Mobile Workstyle to configure my mailbox in the office. Is this a problem? What should I do to restore it to normal screen or Original (without text box and the OK button).
Try this
Settings > general > reset > reset all settings

How to set up make-style for the text box in the apex.

I created a text box in the apex and now I'm changing the font for that text box style and I applied here like this is this correct one or any suggestions on this.

-- HTML Form Element Attributes: style="font-family:Arial;font-style:Regular;{code} The apparoach is the right one or not.
N ° attribute is missing a quote from endpoint, and "Regular" is not a valid value for the http://reference.sitepoint.com/css/font-style">make style property.» Valid values are normal | italic | oblique as shown.
Also, it is recommended to specify a default value of generic downturn at the end of the specifications of font family :
{code}
style = "do-family: Arial, Helvetica, without serif;" make-style: normal; »
{code}
(There's really no need to ask such questions icies and waste of time to wait for answers: to bookmark a good reference CSS like Sitepoint link above or the http://www.w3.org/TR/CSS21/#minitoc"> W3C CSS specification and refer to them as needed.") -
Erratic text box near the border of an image
Dear members,
All the world has noticed this problem? Insert a framework anchored with an image (such as a jpeg file) to the inside and then insert a text box and enter text. If you move the text box in the image, the text begins to jump around as he crosses the edge of the image and won't settle down until the text box is at least 1/8 inch away from the edge of the image.
Is it possible to eliminate this problem? I tried to send the image back and sending the area of text to the front, but in vain.
It is the framework 7.2 on Windows XP.
Yours,
Michael F
