Check whether the checkbox in a form is activated or not using javascript
When you click a checkbox (TBD) it must set the value of a field with a default value "1234". If uncheck us the box, it must set the field to null.I set the box as STATIC2:; 1234 in the form.
I used the event onClick on the box and calls a function to update the column.
Inside the function I check if the box is checked using
If (document.getElementById('P4_TBD').checked = true)
{
document.getElementById('P4_COL1).value = '1234';
}
on the other
{
document.getElementById('P4_COL1).value = "; / * or $s ("P4_COL1", "");
}
It works only when the box is checked. If the checkbox is unchecked is not setting the field to null.
I checked document.getElementById('P4_TBD').checked = false instead of the else clause. It does not work.
Please help me on this issue.
Thank you

When you use the check box or option button, your button ID is using an index. If you create a group of 3 check with ID = "MY_CHECKBOXES" boxes, APEX will create the following ID for each of your options: MY_CHECKBOXES_0, MY_CHECKBOXES_1 and MY_CHECKBOXES_2. If you want to test if the first checkboxe is checked, you will use document.getElementById('MY_CHECKBOXES_0').checked.
I didn't test a single checkbox, but I would expect your check to be "TDB_0" not "BDM" which is the frame that surrounds your checkbox group.

After the cancellation of my subscription, why can I not use my old previous Adobe products?
I thought my old apps (CC and CC2014) would always work
N °
When you cancel your subscription, all software related to that subscription will stop working. This includes any software with CC in his name.
The only way to continue to use the CC versions is to re - register.
All versions perpetually under license that was purchased before you subscribed for example, CS4, CS5, CS6 will continue to work as usual.

check whether the work of clone was successful
Hi all
today I am cloning of virtual machines with my vCenter (scheduled tasks) and I remove my clones with PowerCLI Powershell.
But if Te my data store is full, the work of clone will be not successful, in this case, I want to get an alert.
How can I check whether my work clone was successful?
Thanks in advance
You can try:
(Get-Task | Where-Object { $_.Name -eq "CloneVM_Task"}).State
The Get-job cmdlet retrieves information about current or recent tasks.
The status value returned is error, pending, running or success.

Is it possible to check whether the action of a defined action exists?
In the script photoshop (CC 2014) I will execute action with action and action game that you may not be able to add more. I wonder if I can somehow checks to see if the action is first.
all the code that I have:
document = app. Open (new file(Fichierentree));
some check if there is such action?
app. doAction (actionToRun, actionSetToRun)
The easiest way is to run the action. If it throws an exception, check to see if it is the exception for missing action.
document = app.open(new File(inputFile)); try { app.doAction(actionToRun, actionSetToRun); } catch (e) { // Check e to see if it's the missing action exception. }
Or you can use this extracted from xtools/xlib/stdlib.js.
function hasAction(atn, atnSet) { function cTID(s) { return app.charIDToTypeID(s); }; var asetDesc; var rc = false; var i = 1; var asMatches = []; while (true) { var ref = new ActionReference(); ref.putIndex(cTID("ASet"), i); var desc; try { desc = executeActionGet(ref); } catch (e) { break; // all done } if (desc.hasKey(cTID("Nm ")) && desc.getString(cTID("Nm ")) == atnSet) { asetDesc = desc; asMatches.push({ index: i, desc: desc}); //break; } i++; } if (asMatches.length == 0) { return false; } for (var i = 0; i < asMatches.length; i++) { var asmatch = asMatches[i]; var asetIndex = asmatch.index; asetDesc = asmatch.desc; if (!asetDesc.hasKey(cTID("NmbC"))) { continue; } var max = asetDesc.getInteger(cTID("NmbC")); for (var j = 1; j <= max; j++) { var ref = new ActionReference(); ref.putIndex(cTID("Actn"), j); // Action index ref.putIndex(cTID("ASet"), asetIndex); // ActionSet index var desc; try { desc = executeActionGet(ref); } catch (e) { break; // all done } if (desc.hasKey(cTID("Nm ")) && desc.getString(cTID("Nm ")) == atn) { return true; } } } return rc; };

I can't go to the Java website to download the updates in the Firefox browser and it will not go to other sites that use JavaScript. I tried disabling my firewall, but this makes no difference.
I noticed with some sites I can enter them, but I cannot view items that have been created with JavaScript, for example. my own Web site at http://shaedandu.com.au... Some objects such as my Thawte security seals do not appear, and even other people tell me that they appear on the live version that they see in their browser.
I cleaned my internet cache several times in the last week... Return to Windows Internet Explorer help either, even though I prefer Firefox my default browser.
Can offer you a solution?

[Melbourne - Australia]Ok... Looks like I'm tackling the problem from the wrong end!

PDF forms: extraction of data fields using javascript
Hi, I was wondering if someone could help me...
I have created a PDF form which, once the user fills out the fields, he or she will click on a button to send the form by e-mail to their Manager. Once the registration form is authorized by the Director, the Manager will be click on another button, which will forward the form to the original user. The user would have filled their email address in one of the fields in the form. Is it possible to extract data from the field e-mail address using javascript?
Thank you very much!
You would have to do something like this:
// Get the email addresses var email1 = getField("email1").valueAsString; var email2 = getField("email2").valueAsString; // Send the email try { mailDoc({ bUI: false, cTo: email_addr1 + ";" + email_addr2, cSubject: "The subject of the mail", cMsg: "The message body of the email" }); } catch(e) { app.alert("Could not send email, sorry.", 1); }
Note that the e-mail addresses must be separated by a semicolon, as shown. Also, affecting false bUI will only work if the code is run form a privileged context, as in a JavaScript file to the folder level.
If you want to hard-code one of the e-mail addresses, it would look like:
cTo: email_addr1 + ";[email protected]",

Clear all the checkboxes in a form at a time
I am currently working on a form that has a self-test function, something of a cram for students before an exam. At the end of each chapter, I have a button to mark the self-test and the other for clear responses. For the latter, I used code similar to what is below. I wonder if there is a way to clear all checkboxes at once, so I can't list them all.
//Question 1 this.getField("C8_1A").value = "Off"; this.getField("C8_1B").value = "Off"; this.getField("C8_1C").value = "Off"; this.getField("C8_1D").value = "Off"; //Question 2 this.getField("C8_2A").value = "Off"; this.getField("C8_2B").value = "Off"; this.getField("C8_2C").value = "Off";
If you use a hierarchical namespace and give each box with the same prefix (for example, A.C8_1A, A.C8_2A, etc.), you can dismiss everything with a single statement:
Reset all the Group A of the fields
resetForm (["A"]);
This will reset all the fields in the document:
resetForm();

Tree with hierarchical function to check/uncheck the checkbox
Hello
I build a tree with checkbox APEX 3.2 feature
My query tree looks like
Select "SERVICE_ID' id
"PARENT_ID" pid
, The name of 'service_name '.
connection null
APEX_ITEM. CheckBox(1,SERVICE_ID) a1
null a2
of ' #OWNER # '. " SERVICES_TEST ".
Start with "SERVICE_ID" =: P9_TREE_ROOT
connect prior "SERVICE_ID" = "PARENT_ID".
So far so good. The tree displays correctly
Now my requirement is check_all_child/uncheck_all_child when the parent is checked/unchecked.
Let's take an example like
ROOT
-SERVICE1
-SERVICE1_CHILD1
-SERVICE1_CHILD2
-SERVICE2
-SERVICE2_CHILD1
-SERVICE3
If SERVICE1 is checked, then SERVICE1_CHILD1 and SERVICE1_CHILD2 must be verified.
Could someone help me please on how to do it?
I can write a function onchange against the box, but I need to check/uncheck hierarchically and the hierarchy is dynamic.
Please let me know if any other information is required.Amri,
Try the following$('[name=f01]').click( function() { this_checked = this.checked; this_row = $(this).parents('tr:first'); this_level = this_row.children('td').size(); next_row = this_row.next(); /* Loop through next rows and use the no: of columns to identify children */ while ( next_row && ( next_row.children('td').size() > this_level) ) { next_row.find('[name=f01]').attr('checked', this_checked ); next_row = next_row.next(); } })
