Read the value of the element in the HTML header

Hello
I put a point value ex P1_ITEM page using a process before header and in the header of the HTML Page, I add in javascript
'var str = document.getElementById('P1_ITEM').value;' to get the value of P1_ITEM, but it is always empty.
Anything wrong with that?

Thank you

Vincent

Vincent,

Sometimes the examples help me identify what I should have seen it before...

JavaScript is not in a function and is therefore executed as soon as the browser reads it. In this case, the JavaScript code is before the question so it cannot get the value. You will need to place the JavaScript code after the element or put it in a function and call it after processing of the element - preference onload or using jQuery is ready function.

Kind regards

  • indentation of the HTML/head/body tag

    A question preferably, I like to indent the content of my tags html, head and body (see code examples).

    It was a boring soft than Dreamweaver don't indent by default when a new page is created. I have finally is broken down and hunted for a preference to solve this problem.

    In the category layout of the Code, I found the tag library Editor, who seems to have the exact settings I need. However, even with content formatted value and Indented for the html, head and body tags, recently created pages don't have still not any withdrawal.

    I wasn't able to find any other settings related to this. Does anyone know of a solution? As I said, it's just a minor annoyance. Indenting manually is not a huge deal.

    Actually, nevermind. I answered my own question. I was able to modify the default documents in the Adobe Dreamweaver CS3\configuration\DocumentTypes\NewDocuments\ folder, and the changes that I've made to these files appear when I create a new document. Seems like this another parameter should have worked too well.

    Hello

    It can be used for many purposes, I will try to provide significant,

    When you add your site in Google Webmaster Tools, you get a meta tag, you need to add to the title of the head section, this helps Google to verify that you own the site, and they will keep you up-to-date about the performance of the site in the results of research.

    It's the same thing for Bing Webmaster Tools, Google Analytics and many other things. All these things will help to improve the Site's performance in search results.

  • Cannot read the response header - short read

    I have a MacBook Pro with Mac OS X 10.6.8.  I also have a HP Photosmart C4700 printer.  Yesterday, I started to get the message that precedes, when I tried to print.

    Went on this forum and we tried all the following features based on what has been proposed.

    In system preferences, I deleted and added the printer again.  Disconnect all cables from the printer, it turns off, then reconnected.

    I also downloaded all my Mac, more went into disk utility, updates repair the drive, rebooted, then reseset the system of printer options which meant reinstall the printer.

    No go.  Still get the same message when printing, as well as documents are saved in the stack of the printer, the printer paused.  Sigh.

    Any further suggestions?

    I would skip the first part. From the second section of the steps numbered by resetting the printing system. I hope that will get it repaired for you.

    Let me know the results and we can go from there.

    Good luck

  • Read the HTML of the text and use it (like XML)?

    OK, here's my situation, why I want to do this:

    I run a website for a collectible online cards game. This site collaborators can create jobs and a separate server (c#, APEX Server I run do not like sony authentication system) program then connects to the site of the original game and made the trades. I would like as a service on this site the ability for my users to 'download' their collection on my site at the same time. Naturally, I can access their collections as they are on secured accounts and requiring their login data. What I can do is to ask them 'view-source' their page collection and based on this information together HTML downloaded on their collection.

    BUT how to make this easy with functions as in an accessible object HTML code: getElementsByTagname()? Or a parser of XML documents / would suffice?

    I tried searching on the internet but did not directly find anything related directly!

  • Limit size of JavaScript in the HTML header?

    Hi all

    I added some javascript in the header HTML tabular form. When the javscript code size increases more than 26.6 KB, my form doesn't work - it gives just 'Not found' error instead of the page. If I reduce the size of the JS code to 26.5 k or below, it works very well.

    How can it be controlled? I need to add more JS for various checks.

    Thank you

    When you have a lot of javascript code, you can put in one file JS download on/i/images or files (shared components-> static files) in your workspace and static load from there. This makes it easier to maintain, too.

  • Setting the value of an element of Application (defining a global variable);

    Apex 3.2.0.00.27, I need to initialize a global variable to 0 to implement a variable to test to see if something on the page has changed. Will update to 1 when some lists of selection on the page are changed. Read through a few similar questions and answers within the forum, as well as blogs and other sites. So, I think that what I do is the way forward in this regard. Unfortunately, my point/global application initialization is not past yet. Here's an overview of what has been implemented:

    1) has created an element of demand, G_CLASSIFICATION_ID_NEW in the shared components.
    (2) created the Javascript (JS) function called by addLoadEvent area header html page so when the page is loaded, the application global/G_CLASSIFICATION_ID_NEW element should be set to 0 with the following JS and using AJAX and htmldb_GET:

    < script type = "text/javascript" >
    function initVars()
    {
    Alert ("before the initvars get");
    get var = new htmldb_Get (null, $x('pFlowId').value, null, 22);
    Get.Add ('G_CLASSIFICATION_ID_NEW', 0);
    gReturn = get.get ();
    {if (gReturn)}
    Alert (gReturn.value);
    }
    get = null;
    Alert ("after get initvars");
    }

    Alert ("before the call to the initpage");
    addLoadEvent (initVars ());
    < /script >

    I used the htmldb_Get successfully to populate other global variables and processes on request with onchange THAT JS call in the attributes of html form elements select list on the page. Later, I check the globals via the Session view and research on elements of Application. Unfortunately, I'm missing something, because my G_CLASSIFICATION_ID_NEW never gets filled when I load the page. The Alerts popup every when the page is loaded, so I know that the script is running when the page loads. alert (gReturn.value) is not defined. And, of course, the G_CLASSIFICATION_ID_NEW to 0 does not place.

    I tried the htmldb_Get with her call for a process of application and without (null value). What I read, you should not need to call an application process to have the get.add of the value of the global variable. Here again, this could be where I'm wrong. However, as I mentioned, it works for the other functions called from an onchange to fill a part of the application, but the page has already loaded when the onchange (s) executed. They can work because the page is already loaded when the onchange is called. My point here is that my other on application processes are NOT set or modify global variables at all. The globals are preparing with the get.add (< element app >, < value >) part of my other JS works within the HTML header area. So I'm inclined to believe that I don't need 'application_process = < some_odp >' set parameter, but if it is not true, please let me know. If so, what should be in the application process-that is to say, what would be the purpose of the get.add (< application item >, < value >) if I set the global variable in the application process on because it's the only thing I could think to do within an application process on for this?

    If someone can point out what I'm not understand or, failing to do it here, that would be great. I am doing fine with APEX, but don't consider myself a guru with it immediately. I'm certainly not a JS/AJAX guru, and when things like that, go astray, I get bogged down because I'm not sure of the problem. So, I hope that you gurus who monitor this forum can get going in the right direction.

    Thank you

    You can use the following syntax in the header, html body, or the footor in your area:

    & P1_ITEM.

    And commercial front and end point are needed.

    If you want to format, you can use the following

    < span style = "make-weight: bold;" "color: darkblue" > & P1_ITEM. </span >

    Hello

    Loga is correct on the use of firebug with firefox. However, if you use IE (version 8 or later), press f12 to switch to developer mode. For Chorme, click the right button of the mouse, you'll get a context menu, you can see "Inspect element", which will have the HTML for this object. Yes as Loga said, if you can simulate changes by using these three, you can bring the apex thro generator only changes required, applying changes to CSS, script, models etc. Hope it will be useful.

  • read the values of an array element and by sending a digital output to a designated channel according to the value read from the table

    Hello world

    could someone help me before I get out of my hair. Here's my problem.

    I read 3 values of an array of 3 elements i.e. 1,2,3. These values are then compared to a constant value, example if the first element of the array is 1 and it meets the comparison condition can send a digital camera of output for that channel on data acquisition

    I want to be able to send a value from a table to its corresponding comparison and then on its designated channel on the acquisition of data, the whole point of this is due to the fact the table element will not always read the value 1,2,3 for example could be 2,3,1
