How to trigger a javascript validation
I have a form that accepts volunteers information and uses spry fields, it works fine(DW CS4). My users have asked that, in addition to the validation of a field of e-mail to be a valid e-mail address format, they want the user to enter their e-mail address twice and then make sure that both are the same. I must be missing something blinding because I can't understand how to trigger the code js of edition to compare fields two e-mail.
The page is here www.hollisterairshow.com/volunteerapp3.php
Here is the js code change that appears in the header section of the page:
< script type = "text/javascript" >
If (form1.getElementById('email').value! = form1.getElementById ('email2') .value)
{
Alert ('-address Email and confirmation do not match\n');
Returns false;
}
< /script >
Here is the code for two e-mail fields in the form that appears in the body of the page:
< b >
strong e-mail address > < td > < <: facilities > < table >
< td > < span id = "sprytextfield1" >
< input name = "email" type = "text" id = "email" / >
< span class = "textfieldRequiredMsg" > please enter your e-mail address </span > < span class = "textfieldInvalidFormatMsg" > Invalid format. </span > < / span > < table >
< /tr >
< b >
< td > < strong > re-enter E-mail: < facilities > < table >
< td > < input id = "email2" class = "cat_textbox" name = "email2" maxlength = "255" / > < table >
< /tr >
Here is the code for the button 'send '.
< input type = "submit" name = "submit" id = "submit" value = "Submit" / >
I know I'm missing something very basic, but I have not the slightest idea of javascript. Thanks in advance.

Nevermind - I fixed it after several hours of fiddling around with javascript. In case someone else has this problem here is what I did:
I created a js function which compared the two fields and issued an "Alert" message if the fields were different. The function is shown below
function displayResult()
{
var $em1, $em2
$em1 = document.getElementById("email").value;
$em2 = document.getElementById("email2").value;
If ($em1! = $em2)
{
Alert (' email address and its confirmation no match\n');
Returns false;
}
}
In the body of the form, I triggered the function using the event "onblur" as shown below
Please enter your email address Format invalid.

How to trigger the dictation from the smart keyboard on the iPad pro.
I use dictated on my iPhone and my iPad quite often.
However on my new iPad Pro with the smart keyboard attached, I do not how to trigger the dictation from the keyboard.
I don't see how to get the soft keyboard back to press the button of the microphone are there, such space suggested by some on this forum.
This doesn't seem to work in the latest iOS Update 9.
I would be fine with a hotkey, or have to invoke the keyboard of the shop, then press the button of the microphone, but I don't see how do either.
When the Emoji button on the keyboard smart strike as the keyboard, the software keyboard emoji is displayed, the space but when I press the soft ABC capital but I cannot get to the regular keyboard with the microphone button.
A possible alternative would be to use Siri to dictation trigger in recording a memo or another application, space but I didn't understand how to do this job either.
Has anyone experience this problem and found a solution?
Unfortunately I had to spend a good hour on the phone with technical support when they finally admit that it was an oversight by Apple. I hope someone reads this post until they spend countless hours trying to understand something, but has no solution at the moment. Frustrated!

HOW DO I RETRIEVE MY VALIDATION ON MY COMPUTER
PLEASE PLEASE PLEASE, CAN SOMEONE ME SAY HOW DO I RETRIEVE MY VALIDATION WE MY COMPUTER WHATS RUNNING WINDOWS 7, I TRIED WINDOWS 10, IT WASN'T FOR ME UNINSTALLED IT BACK TO WINDOWS 7 NOW ITS SAY; THIS COPY OF WINDOWS IS NOT GENUINE, WHEN I KNOW THAT IT IS THAT I'VE HAD THIS COMPUTER FOR TWO YEARS.
Help, please

Uninstall windows 10-7
You will probably never get Windows 7 running again, until you perform a new installation of Windows 7.
I recommend a factory restore. There is a hidden on your hard drive partition (assuming you have the original OEM hard drive) that has a copy exactly what was on your computer when you first started it. Factory restore does not require a product key or an installation disk.
Tell us the brand and model and we will send you instructions on how to perform this.
First of ALL, download your saved data. Factory restore erases all

How can I run my validations after confirming that a specific field is not NULL?
Hello
How can I run my validations after confirming that a specific field is not NULL?
One of my validation needs to ensure that a specific page element is not NULL, then I use the option 'required value' of the page element, but it seems that the validation is performed before the option "required value.
I know I could create 2 different validations for each case, but I think it would be nicer if I could work through the only validation and leave the APEX to manage the field validation is NOT NULL
Best regards and thanks for reading
According to my experience, it appears that the APEX is going through all THE postings...
IE, if a "failure" of Validation continues.
It's actually beneficial for the end user, because it will get ALL the errors in the form he or she made... not just a first.
workaround solution:
- Remove the 'required' on the element value (.. but keep the "required" model)
- Add the NOT NULL check to your personal validation process.
Very probably, the 2nd one will be in a PL/SQL function return error text.

How can I compress javascript and CSS files in my export of Muse?
How can I compress javascript and CSS files in my export of Muse? When I test my Web site with website speed test in pingdom (http://tools.pingdom.com/fpt/)
the site has a low rating in the category of the number of CSS and javascript files because there is so much of... Is there a way to reduce the number of CSS files
that are generated?
In addition, the code we can place in Muse to tell Javascript to load last so it won't slow down the site are there?
Thank you
Theresa
Regarding your first question. There is no way to compress the code CSS or javascript in files of Muse.
When Muse exports a site it generates the CSS code for each page. There is no way to combine code similar to a lot of pages on a site by using Muse. (it is not the same process that build you using Dreamweaver or php coding)

How to trigger the new numbering of the lines in a group?
Suppose we have an ORDER_DETAILS table with columns (ORDER_ID, LINE_NUMBER, DESCRIPTION).
We have these lines:
order_id, line_number, description
17: 1, "A".
17.2, 'G '.
17.3, 'R '.
17.4, "Q".
Next, it inserts a new line
17.2, 'K '.
How to trigger the renumbering?
This should be the result after renumbering.
17: 1, "A".
17.2, 'K '.
17.3, 'G '.
17.4, 'R '.
17.5, "Q".

How to trigger LR to throw standard previews?
This is NOT intelligent overviews, but previews of library-module. There is no 1:1 previews, but standard previews.
Situation: I use an external SSD as 'disk external catalogue', with my LR catalog and previews on it, in order to plug it in 2 different computers that I use also.
Due to a poorly thought-out import synch-folder that I found myself with side effects and much too many images and previews, so I decided to go back to the last backup good catalog.
So in theory I should have 100 GB of excess saw the version of catalog scrapped, rendered useless for the restored version of catalog.
How to trigger LR to throw away them?
I tried to trigger the generation of standard previews of files, which now contain pictures much less than before, hoping that this would get rid of them. To my astonishment said LR to rebuild almost all previews for the files selected. Why - they should have been here already? Usually, when a version of Catalog backup is restored as current (same name, same clichés), extracts are recognized?
Once this is completed a night later, I still have the same size of the previews folder catalog!
Any ideas?
Before you suggest that I have delete all previews and leave the LR to rebuild from scratch: this is a catalog of 2, 2 GB size, 150'000 images and 190 GB of previews (more than 146 GB of previews smart, although they are not my concern at the moment). This operation will last nearly a week to rebuild... so I would prefer something more simple.
Thanks, Cornelia
Hi Cornelia - long time...
Cornelia - I wrote:
Do I understand correctly that LR would never get rid of previews, at least I have remove an image in the catalogue
Yes, you understand properly - the only way to get Lr to remove standard previews is to remove the photo of the catalog (not sure of the part of the cancellation).
Cornelia - I wrote:
If the images are already missing the older catalog (through a restore from backup), your PreviewExporter Plugin would find their?
Well, if the photos have been removed from the catalog, then PreviewExporter will find previews corresponding (there are only glimpses of the selected photos). (if the pictures are in the catalog, but missing disc, then it will find them). Interesting, even if idea - a function to remove all foreign previews - ' twould be easy enough to make, just has not yet done.

How to check the RegEx validation
Hello
My application needs to users to enter the regex. My question is how I can check the validation of the regular expression that users enter. The RegExp class does not provide any methods to check the regular expression validation.
Kind regards
Haibin
You need to hand roll your own validator, unless someone knows of who is there. Flex does not validate the RegEx.

ODI: how to trigger the error return prior to loading in Essbase?
Hi John... If you read my post, I want to say that you impress me! really, thank you for your blog.
Today, my problem is:
-J' received a poor quality of extract of ERP data file
-J' saw the reference table (Source == > target)
-> > How to trigger the error prior to loading in Essbase!
My idea is this, (first of all, I don't know if it's a good thing, and also I have the problem to do in ODI!)
-Step 1: make the JOIN between data.txt and cross-reference Table == > create a DATA_STEP1 table in the ODISTAGING schema (columns of DATA_STEP1 are adding data.txt columns than the table of cross references (... there more than 20 columns in my case))
-Step 2: Control if there is no NULL value in the target column (NULL means that the data.txt file contains the value that are not defined in my Table of cross references) by using the filter (filter = Target_Account IS NULL or Target_Entity IS NULL or...)
The result of this interface is sent to the queue of reject.txt - if reject.txt file is not empty, then a mail is sent to the administrator
-Step 3: do the opposite: filter NOT (Target_Account IS NULL or Target_Entity IS NULL...) == > the result is sent in the DATA_STEP3 Table
-Step 4: run correctly mapping: source: DATA_STEP3 (own and verified data!) with reference Tables and send data into Essbase - NORMALLY, it is not rejected record!
My main problem is: what is the right IKM to send data in the DATA_STEP3 Table, which are the Oracle Table in my scheme of ODISTAGING or DATA_STEP1! I tone with Oracle IKM incremental update but I get error and in fact I don't need an update (which is a time trust), I just need an insert!
"I'm just lookiing for a ' IKM SQL for Oracle...
concerning
XavierCreate a sequence in oracle, you use the sequence in the mapping of your target.
< %="odiRef.getObjectName" ("l",="">
"," ","< d="" ou="" w="">") %>.nextval" so, for example, it might be
<%=odiRef.getObjectName("L","DATASEQUENCE","DATALOGICALSCHEMA","D")%>.nextval
Make sure that you run the mapping target or intermediary.
See you soon

How to make Unique key Validation
ADF 11, ADF, BC.
I could be missing something, but how do you add a validator for a unique key?
I have a unique key defined on the DB, this unique key has nothing to do with the primary key.
(Its audit that a code is unique)
In the validators on the entity object, I can put a unique key validator, but it lists only the
primary key for the definition of not check unique key...
The unique key on the DB works as I get a nice constraint violation error, so how can I
Add a validator to a single key or at least catch the error to display a friendly message.
Concerning
PaulHello Paul,
My recommendation would be to leave the validation of the uniqueness constraint in the DB. Have a read of the article 37.8.3 (updated for 11g, 10 g, it is 33.8.3) guide the developer of Fusion, where you will find a way to provide your own rather than the ugly constraint violation a nice error messages.
Best,
John
