Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Possible to use Javascript to trigger an Xbasic Button.Click event from a ButtonList.OnClick event?

    OK this might be slightly tricky, I am stuck, so time for another forum post, yay!


    I have a ButtonList

    followed by two regular Buttons, let's call these Button1 and Button2

    What I am trying to achieve is...



    in the ButtonList.OnClick event

    first I run some javascript


    then I want to trigger in turn, the Click event for Button1 and Button2


    Button1 runs Server-side Xbasic which outputs Javascript to the client via Ajax callback


    Button2 opens a linked grid using Action Javascript.

    I can trigger Button2.Click from my ButtonList.OnClick easily enough

    because in the builder for the Button2 Edit Click Event
    I just press "view javascript" and see it is just this line of javascript
    {grid.componentName}_2A635A2E777D4D1D88E88F6E919FAD1F(this);



    But my problem is Button1

    The Button1.Click event is Xbasic

    Can I trigger it's click event using Javascript?

    I tried putting the following line into my ButtonList.OnClick but it did nothing

    Code:
    {dialog.object}.runAction('serverside_25e008027bbc4499a84542214401afb2');

    I got that long string from the Button1.Click Xbasic event window
    (see picture below)
    HowToTriggerThisEventFromButtonListOnClick.png

    and I thought I would try and trigger via that long name, by using
    {dialog.object}.runAction


    Is what I want to do even possible?

    i.e. Use ButtonList.OnClick event to in turn
    trigger the Button1.Click that uses Ajax callback to run XBasic on the server and return Javascript to the browser

    This is in a UX right? If so, check out:
    Code:
    {dialog.object}.buttonClick('BUTTON_1');
    //Click the button in the 3rd row of a Repeating Section
    {dialog.object}.buttonClick('BUTTON_1:3');

        No problem,
        The runAction is for javascript actions (not action javascript which is inside individual events) that you create. If you go to your UX properties pane on the left of the builder and look under "Javascript" you will see "Javascript Actions" and you can build them there. You can then use runAction and the name of your action to run them within your UX.

        As for button clicking. Just an FYI as people run into snags with this, the button click method won't work on buttons that are hidden on the server-side since the buttons don't exist after render. If you hide them client side it will still work. This can be handy so you can create one button that get's clicked from multiple buttons or rows so you don't have to keep rewriting the code. You can also use Jquery/Javascript that's built in to Alpha:

        Code:
        $('DLG1.V.R1.BUTTON_1').click()
        And variants thereof to do what you'd like.
        "$" in the above case is really short for document.getElementById

          So then can I also run any Javascript Function that I write, using runAction? I will check it out.

          And yes as for the buttons that are only called externally for their click events, I used CSS to hide a few things, with style =
          display: none;

          I quickly realized the controls fully disappear, events and all, if setting the Hide checkbox to true

          Thanks for all the tips. Just got my app to the next completion stage, cookin with gas now

            JavaScript functions are a different beast. Yes, you can write a function and call it (including passing variables into it) but it is not the same as an action and, AFAIK, can not be called by "runAction". Think of Alpha's JavaScript actions as Action JavaScript that can be called from any event instead of just in the individual event in which it was defined. Yes, you can do that with functions but functions are straight code. The other two types are Alpha's way to build that code for you.

              Guys while you're at it can you check if writing {dialog.Object}.buttonClick( then doing CTRL-Down Arrow brings up the list of buttons in your UX?

                I think the {dialog.Object}.buttonClick will only trigger a named Button control

                But if you created a Button control that in turn ran it's own javascript to do CTRL-Down Arrow you might be able to do it.

                e.g. http://stackoverflow.com/questions/5.../596580#596580
                Code:
                function simulateKeyPress(character) {
                  jQuery.event.trigger({ type : 'keypress', which : character.charCodeAt(0) });
                }
                
                $(function() {
                  $('body').keypress(function(e) {
                    alert(e.which);
                  });
                
                  simulateKeyPress("e");
                });

                  Hi Michael i think you misunderstood my question.
                  A feature i use a lot in Alpha Anywhere is the ctrl-down arrow that gives you a list of available controls that fit the command you are using.
                  For instance, write {dialog.Object}.setValue( then press ctr-down arrow and you will see the list of available controls in your ux, then selecting one control will copy it's name to the setvalue command.
                  Although the help for buttonClick() states this feature is available, when i tried in buttonClick it didn't popup anything, that's what i wanted you to try...

                  Nevertheless, your simulateKeyPress function will prove extremely useful :-)

                    Jaime,

                    You have to delete everything out of the method before the ctrl down will work. For instance, if you copy and paste this into your event:
                    Code:
                    {Dialog.object}.buttonClick()
                    and then go between the parenthesis, it should work, but if you copy and paste this into it:
                    Code:
                    {Dialog.object}.buttonClick('BUTTON_1')
                    it won't show up. At least until you delete everything in between the parenthesis.
