Java Script in a header on a html page in an apex application
I have the following function in the html of a page header in an apex applicationfunction calc(pThis){
if(checkItem (pThis)){
var lName = pThis.id.split('_');
var lName2 = [];
var gCalcRow = 0;
var gCalcCol = 0;
var gCalcTotal = 0;
var lTable = $x_UpTill(pThis,"TABLE");
var gInputs = html_Return_Form_Items(lTable,'TEXT');
var gRow = pThis.parentNode.parentNode;
gRow = gRow.cells[gRow.cells.length-1];
var gCol = pThis.parentNode.cellIndex;
gCol = lTable.rows[lTable.rows.length-1].cells[gCol];
var gTotal = lTable.rows[lTable.rows.length-1].cells[gRow.cellIndex];
for (var i=0; i<gInputs.length ;i++){
lName2 = gInputs.id.split('_');
if(lName2[1] == lName[1]){
if(gInputs[i].value-0 != ""){
/* calc row */
gCalcRow = gCalcRow + (gInputs[i].value-0);
}}
if(lName2[0] == lName[0]){
if(gInputs[i].value-0 != ""){
/* calc column */
gCalcCol = gCalcCol + (gInputs[i].value-0);
}}
/* calc total */
if(gInputs[i].value-0 != ""){
gCalcTotal = gCalcTotal + (gInputs[i].value-0);
}}
return;
}
I only wish to calculate totals if the values in the gInputs fields are not null I have added the if(gInputs.value-0 != "") statement however when the code executes is raises a NaN error, I have no real experience using java script so my syntax could be way off.
Any help would be great

Hello
NaN is the return of JS for not a numbercode.
The user this feature to test the digital
function isNumber(n) {
return !isNaN(parseFloat(n)) && isFinite(n);
// Return TRUE if n is number , else returns false
}
Add the function above in your header HTML script
Change your code to use this feature
//if(gInputs.value-0 != ""){if (isNumber(gInputs[i].value) ){/* calc column */

Building simple HTML Page at the APEX
Hello
I am very new in APEX and this is the first project of mine to try to convince my organization as a good tool to use. I'm mainly a developer of forms. So, I'll build a Workbench for the Group profits in my company and my first page must be just a homepage with static text and a couple of links to launch my next pages. I added a blank home page at my request and then to EDIT the properties of the region on this same page, I type my static text and it is coming in the text mode free movement, I want to change the fonts, the sizes of some texts and give new lines etc..
My question is that I have to write HTML code to achieve this in the part of the source text?
Thank you
Vishal Vishal,
Yes, if you create an area HTML, you will have to manually put your HTML in there. APEX does not give you a WYSIWYG editor (as I know), but it should be easy for them to do - one of the options for creating an input field is a rich TEXT Editor. I don't know why they didn't implement which.
My personal recommendation for HTML static is to change in your current Favorites out of the editor and then copy - paste the HTML code in the APEX.

You may not use the PHP header function after that whatever it is sent to the browser. Whatever it is. You can have 100 lines of PHP before the header() function as long as the script nothing sent to the browser.
So your options are to revise your code accordingly or use a javascript alternative, as in this example, where a little embedded php sets the real url, but javascript is used to treat:

How to create indesign using Java Script
I am new to indesign and want to create indesign application using JavaScript.
When I use AppleScript to create the Application Indesign I use this statement
Tell application "Adobe InDesign CS5.5"
myDocument to make document with the properties of the value
tell the end
Application InDesign create successfully.
How to create the Application Indesign using JavaScript?
or what is set equivalent to (tell application "Adobe InDesign CS5.5") in Java Script.
There is a sample java script given on the forum or in the sdk. These departure example with app.
When I debug these java script using ExtendScript ToolKit 3.6 it gives error on app (application not defined). I think that this app AI application object.
How to create indesign application object app in javascript?
Although this script runs successfully when I put these script in C:\Program Files\Adobe\Adobe InDesign CS5.5\Scripts
and executing these script use the Scripts panel (choose window > utilities > Scripts), and then double-click the script name in the Scripts panel in indesign application. But in this case I have indesign application start and then choose window > utilities > Scripts, and then double-click the script name in the Scripts panel.
I want to create Application Indesign (instance), using JavaScript.When I run or (debug) my JavaScript in any javaScript tool as ExtendScript ToolKit 3.6 then Indesign application should start, as in the Apple Script.
Thank you
long story short... NO!
However, if you run the script from ESTK, you need not copy the script in the folder "Scripts". Do not know exactly if that's what you want.

TypeError: this.oRoot.enable is not a function
This is popping up when I befor I open my browser,in a pop up box under the heading JAVA SCRIPT EXE. What is it, how do I get rid of it?
For me, this happened from disabling, but do not uninstall McAfee site Advisor. Recommend site completely uninstalled and the problem disappeared completely. I had turned off before site Advisor, but it seems after a update to McAfee, he was back and then turn it off again caused this problem.
Go to "uninstall a program" or "add/remove programs" in control panel. Find McAfee in your list (McAfee total protection for me). Click it and then click "Uninstall/Change" (right there in XP, up above in Vista or 7). I don't remember exactly what you see after that, but at one screen I was given the choice to uninstall the McAfee total protection and/or the Site Adviser. You can just check the Site Adviser and just uninstall the Site Adviser while retaining the rest of the McAfee protection.
Good luck!

Hello!
I am a new user to adobe creative cloud. I'm a Web site manager for pge production broadcast in my school and I use squarespace but I want to upgrade and have more opportunities with my websites. Adobe has tutorials on Java Script, HTML, and CSS?
Not in the way, I think you mean. There are a number of very generous gurus on this forum that will help hard problem solve you your code, and the best way to learn is always, spoil, figure it out and move on to the next thing. :-)
Googling a question will generally help to guide you on the right track and you can always visit W3 Schools or Code Academy for free tutorials or check if there is a Free Code Camp in your area. Sources for tutorials or classes are Lynda.com, Noble of officeand the General Assembly.

How to enable the Java Script function in APEX 4.2.6 running on the result of an Xquery query.
How to take a SQL query result in the source section of an APEX "agenda of the page" field and allow this request to be formatted using XML in an HTML format for a Java Script file to perform a function on the result?
Currently I have the following text:
To query the DB table and format the result as HTML:
SELECT XMLELEMENT ("UL id ="ticker01"', XMLAGG (XMLFOREST (Scroll_Mess AS LI))") "item UL' OF Web_Ticker where Mess_Id < 10 order by Mess_Id;
That displays the following:
< UL id = "ticker01" > < LI > HELLO < /LI > < LI > HELLO < /LI > < /UL id = "ticker01" >
I need the output of this to be visible to a JScript function that is currently called the "head of page", but there doesn't seem to be its scope? The function works correctly if there is a list in the page field items 'Text element Pre' but does not work correctly when used in conjunction with the query to generate a table form.
If everyone is happy to help I would be grateful .
James.
Solved!
In order for the request to be part of the DOM of the page of the APEX, the Java Script allows to perform its function on the result marked "HTML" to query, you must set page of the apex on which the query resides and then add the inner text of this page to a second variable for which the function of web ticker can run on as follows:
$(function() {})
var x = $("#P9_TICKER_DATA");
var y = x [0] .innerText;
x.Append (y);
$("UL#ticker01").liScroll ();
});
From there, on the Java script is able to properly see the result of the query in HTML format.

Hi guys,.
I would try to explain my problem.
I have two Select lists P58_TYPE_DOC (it displays for users with no SMA profile) and P58_TYPE_DOC_ADM (it shows just for the administrator).
On my Page of propriety I header HTML copy the following code:
OnLoad = "show_fk_facture ('P58_TYPE_DOC'); show_fk_facture ('P58_TYPE_DOC_ADM'); »
I need to run java script when the page is loaded, but I can't run the function for both items at the same time.
Because one of the items will be hidden, and java script won't be able to find it.
I tried to use if "isNAN ('P58_TYPE_DOC') else... "but it does not work.
You have any suggestions?
Thank you

Suddenly this morning I receive a message that Java Script is not enabled. I am not able to access Yahoo! mail, Gmail or iCloud mail. When I search for "Java Script" I get 300 + add-ins, the top 50, or appear not to be simply Java Script. What is the exact name of a supplement Java Script that will allow me to use my e-mail programs?
JavaScript is not an add-in, but a language like basic, C, java and so on. It is often used on web pages to create dynamic effects like the movement of the figures and similar effects. Therefore, it is included in the HTML itself. For various reasons you might want to disable the ability to run java scripts, for example for security reasons and in older versions of Firefox, there is an option in the settings were you could turn on or off the ability to run these scripts. Nowadays, this option is removed, but is included in those more hidden that reach you by writing about: config in the address bar. If you do, you will get a warning "This might void your warranty!" and after clicking on the I'll be careful, I promise!-button you will enter the words: config page. Research of javascript.enabled, which is normally set to true. Double-click this line after selection, press enter on the keyboard and the value is going to switch from the other value, false.
However, you may have loaded an add-on that blocks java script. I can imagine there are a lot of them. One that I use is NoScript, which allows me to choose individually what web sites I will allow running scripts in java on my computer, and who I would not deny this. Take a look of the modules you have loaded, so maybe one of them can block the ability of java script.
