How can a form has been submitted via: onchange = 'this.form.submit ()'

I'm hoping that it might be a simple answer to the question below.

I have a page with a form and the form Send call the same exact page forms on. When I check the form variables after the submit button the form.button2 variable exists and has a value when I use a button to send the page.


However, during the presentation of the page via OnChange ='this. Form.Submit () ' no form variable is being updated to reflect that the page submitted by the user.


Is it possible to force a form variable to update so I can see that the user has come form this control through javascript?


See the code example below and screenshot below


code example...

01

xxxxxxxxxxxxxxx    Example with submit button.   xxxxxxxxxxxxxxxxx

02

<cfdump var="#form#"label="testit">

03
04

<cfif isdefined("form.button2")>

05
06  <!--- Do somthing Here--->

07</cfif>

11  <option selected="selected"> --- Pick Drink ---</option>

12  <option >Milk</option>

13  <option>Coffee</option>

14  <option>Tea</option>

15</select>

16<input type="submit" name="button2" value="Submit">
17</cfform>


XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX


Notice, when I use the onchange = 'this.form.submit ()' he no button and nothing to test to see that the user came from this control xxxxxxxxxxxxxxx example with javascript no button.


XXXXXXXXXXXXXXXXX

Here are the results of the bucket with or without the Send button...


any ideas would be greatly appreciated

Thank you

Use a hidden field instead of depend on the value of the button. The values button is present only if the user actually clicks on the button. By using the form submit event via a code or even the user pressing enter instead of clicking the button will result does no interest button is displayed.

  • How can I form an image?

    Untitled.jpg

    How can I form an image as above?

    Dina,

    But now, how can I do the corrugated and smooth points like in my picture?  And also, I now want to change certain points, like moving a little upwards or downwards... but I tried and it does'nt work. Maybe just, I want to move a point, and not the whole picture.

    You can do so by creating the path to start with:

    (A) by shaping it with the pen tool (which takes a bit of practice which is necessary for any user). You create Anchor Points to a limited number of positions along the way, the pieces together as segments and you click to create straight segments/sharp corners and/or ClickDrag to create curves segments/edges rounded; the landslide creates the lines of Direction with handles that govern the shape of the segments; If you want to adjust the position of an anchor Point when creating it, you can press the space bar and move on, before you finalize the landslide or just let it go,

    (B) by putting in shape with another tool such as pencil, where you draw more as normally by hand.

    In all cases, you can change the path in the future. Speak in a certain way, you can insert Anchor Points by clicking/ClickDragging with the tool, add anchor point, moving from the corner and smooth with the tool points convert to an anchor Point, select Anchor Points specific smoothly with the direct Selection tool and drag the handles, ClickDrag with the tool remodel somewhere on a segment; These tools are supplied with the pen tool and the tool of the scale.

    And another problem... I want to cut a picture with the scissors tool. but it does not work! Really complicated! Why? How can I cut a picture?

    To Illy, a raster image is not a collection of pixels that can be individually / easy to handle, as is the case with Photoshop: him, they are objects, sometimes troublesome objects, which cannot be modified as a whole in some way. And that's where the clipping mask happens to hide unwanted parts (which are still there).

    There is a dirty, destructive way and little messy, it can get rid of the elements unwanted outside the Clipping Path, but if you want to cut a raster image, just like in Photoshop, you will need to do here.

  • Lightroom: Sync has been turned off. This seems to be a backup catalog...

    Lightroom crashed on me and now I get the following message is displayed:

    Sync has been turned off. This seems to be a backup catalog that can be updated with Lightroom Mobile.

    To ensure that your catalog sync, go to: Edit > Preferences > Mobile with Lightroom and click the button "delete all data" to start over.

    I'm in my main catalog, not a backup.

    No one knows how to stop Lightroom to my main catalog as a backup? I don't really want to delete all data and spend the next week re - synchronize their brand-new.

    I use the latest version of Lightroom CC on a pc Windows 10.

    Thanks for your replies. Looks like I fixed it now.

    I was in the main catalog, not a return to the top.

    The issue seems to be with 1 private collection. No synchronization this collection, Lightroom is connected to the Mobile with Lightroom. I allowed him to delete the files in the cloud, then re - synchronize the collection. It seems to work fine now.

  • Edition of Lightroom Mobile Sync - 'Sync has been turned off. This seems to be a backup catalog... »

    Hi, I just tried to synchronize. I am logged on LR5.4 and on mobile. I ran the sync once, that seemed to work. The next time that I'm connected, I got a dialog box saying "Sync has been turned off. This seems to be a backup catalog that can be updated with Lightroom mobile. "To do this, your catalog sync go in Edition > Preferences > mobile Lightroom and click on the button Delete all data.

    It is not a backup catalog, is my main and one alone, but I deleted all the data anyway. No difference. When I start the synchronization immediately made up the dialog.

    Any ideas?

    See you soon,.

    Scott

    Scott, you mention in your post "the next time I logged in." do you have explicitly signed out of sync Lightroom Mobile on the desktop after you sync the first time?  Or you might need to reconnect on the launch.  If it's the latter, this should not occur and could be another indication that the catalog you have signed forward is not the same (that is a backup or a copy that is not state same you were when you last signed in).  This catalog is shared between both machines somehow?

    If you see this and you are certainly not in a backup catalog, you should be able to perform the following operations with Lightroom close.  This will work better if you did remove all the data, even if it is not mandatory.  If you do not, after relaunch of Lr, we will rebuild your sync status which can take some time depending on how much you have synced.  I wouldn't do this for any other situation.

    On OSX: In the Finder go /Users/Data / Sync.lrdata Library/Caches/Adobe/Lightroom/Sync and delete it.

    Windows: In explore go to C:\Users\\AppData\Local\Adobe\Lightroom\Caches\Sync.lrdata and delete it

  • I use 3.6. How can I get the update to look like this? I really don't want to use IE or MSN but if that's all that I have, then let me know. Thank you

    I use 3.6 because I like how it spans my toolbars instead of just me giving bookmarks in the corner and firefox solitaire in the opposite corner. I know that I can open the bookmarks bar, but it's not the same. I want that the file, editing, display, history, bookmarks, tools, help toolbar throughout. How can I get the new firefox to do this

    This should duplicate the image you posted what you look for Firefox 5 in (this application should be BLOCKED) double wire.

    Menu bar

    • Right click on a blank space at the end of the tab bar, click on 'Menu Bar' to place a check mark
    • Checked menu bar = bar menus; Firefox button
    • Unchecked menu bar = bar menus; The Firefox button
    • Other methods of doing the same thing:
      • Click the Firefox button > Options, click on menu bar
      • Quickly activate/disable Menu bar, power: ALT + V + T + M

    Tabs on top

    • Right click on a blank space at the end of the tab bar, click "Tabs at the top" to remove the check mark
    • Tabs on top checked = tabs at the top toolbars
    • Tabs on top unchecked = tabs below the toolbars
    • Other methods of doing the same thing:
      • Click the Firefox button > Options, click on the tabs on top
      • Toggle Quick tabs on top on / off: ALT + V + T + T

    Separate the Reload / Stop button and the position of the Home button

    • Open the Customize; do one of the following:

      • Right click on the empty space at the end of the tab bar, choose "Customize".
      • Click the Firefox button > Options > toolbars
      • If you use the menu bar, click View > Toobars, click Customize
      • Quick open window customize: ATL + V + T + C
    • the buttons Reload and Stop appears distinct between the URL/address bar and the search bar. When the window customize is open, do one of the following categories, to separate the buttons:
      • Drag the button to the left of the Reload button
      • Drag a 'space' between the Reload and Stop buttons
      • Drag one or two buttons anywhere on the separated by a 'space' or another icon Navigation bar or reverse the order of Stop-Reload to keep them separated
    • Drag the button to the right of the search bar
    • Click "Done" in the bottom right of the window customize when you are finished.

    Color backward/forward, home, the buttons Stop and reload

    My hard drive is currently filled by PC DM files in my folder/Public user folder.  How can I safely remove the right files in this folder?  Vista Home Premium 64 bit is my os.

    Hi templar_39,

    DM (Message Delivery) file types are not Windows files, they can be generated by a third-party program.

    This particular file type is often associated with audio data and can be hosted on some cell phones to be used as ringtones or multimedia clips. To my knowledge, these files can be generated by your mobile phone.

    Note: you can go ahead and remove these files only if you notice that the files do not contain any important information.

    If this happens without connect you all devices (like mobile PHONES), this may be a virus or malware activity. You can run a virus scan to get rid of them

    I want alarms to stay there in vcenter alarms tab until I manually acknowledge vcenter 5.1, even though the issue has been resolved. Is this possible?

    I think that it is possible for costom alarm unless if someone this cleat. but for some the alarm settings by default, it will be deleted once the threshold/connection back to normal. to do this, you need to change the alarm and the need to remove the condition that meet as nornmal (means, for this default it will multiple alarm (one is green to red or another is red to green...) so remove settings from red to green. so he will be there until you ack and reset it)
