Prune only to left and spaces of a field

Is it possible to cut only the start and end of a field spaces?  I have a name field, which I shared later so I can generate simply by using the first name, using the rawValue.split method.  This way I can generate an e-mail that says: Dear John, instead of Dear John Smith , drawing from this field.  The problem I encountered there that the person typing the name sometimes leave space a prefix in front of the name, so the electronic message is generated without a name (so it says 'Expensive' Any help is greatly appreciated.


-Very well, thank you for the review to null, your event is good, so good.

Although, if you want to change the value NULL returned, here are the changes to return nothing instead:

function trim (strValue) {}

var str = new String (strValue);

return strValue! is nothing? Str.Replace(/(^\s*) | () \s*$)/g,"") : "";

}

Enjoy!

  • Cannot set Page Muse size correctly - always adds right and left extra space.

    I've set up a page size of 960 pixels wide. It is defined in the master page.

    However Muse Awards left and right by 100 pixels.

    Usually, when you create a new page there is no gray area around the actual page. Only if you add space at the bottom or the top.

    But I can't explain (?) padding left and right. Where did it come from?

    Thanks a lot for help.

    This gray area has always been there since the first version. It is the filling of the browser. It must be there. You can change it to what color you want or add a background image using the browser in the background fill tool.

  • Re: A500 power icon shows only % left and duration (estimated) no real

    Hi I bought an A500 last week. Very happy with its features etc., however, I have a question where the power icon shows only % left.
    For some reason, it does not display the weather remains as it is supposed to. I took it back as long as you 'Out of Box', but the problem persists.

    I rang tech support who told me to take it to the nearest centre of Toshiba. Sms technology had me the next day to say that the task is complete. When I arrived at the shop and asked what was wrong, he said that nothing was wrong. "This model displays only the % and no time. I asked him where he has got that info from, it was Toshiba. He said that he checked the A500 on display for sale in store and that too showed the %. Then I jumped on the view model and verified by myself and here he showed the hours and the minutes remaining. He then said he would have another look.

    He even rang Toshiba who said that he could not be a hardware problem. So basically he and the person he spoke did not have a clue. Portable old man of the week, and I refuse to accept a machine that does not react as it is supposed to. Even the manual user talk taking system a few seconds after the power is cut to calculate the remaining time.

    During this time is there anyone out there who has experienced this or know what the problem is?

    See you soon.

    My a500 also shows % left and no actual (estimated) time :) To be honest, I don't think it's so important to worry.

    > I took it back as long as you 'Out of Box', but the problem persists.

    This means that this feature is not available.

  • T440s - keys alt and space do not work when you press the up and left arrow

    Hi all -

    I just got my T440s a few weeks ago and I love it. I just discovered a weird problem: both alt keys and the space bar don't work when holding the up arrow and left the keys simultaneously. I discovered this while playing a racing game. As holder until left and arrows, by pressing the alt key or the space bar to have no effect, and the laptop makes a sound 'blip '.

    All other keys seem to work all by holding + arrows left and rising + right arrow key does not change a thing.

    I looked at the ease of access settings (I have Win7 Pro 64) and turns off all filters, sticky keys keys, etc. I use the latest version of the BIOS, if that's any help.

    It's a little boring, so I'd appreciate any help. Thank you!

  • How to prune the spaces in a field and run with lov query

    Hello

    I have a customized OPS page and one of the field's element is of type message entered lov. When the user enters the values for this field lov will validate and it will survey exception if the invalid value is entered in the field.

    Suppose that lov is to have values like 100,200,300,400,500.

    Suppose that user enters the value 100 with spaces for towing, so I want to trim left and right and validate the value after all ready for the values of lov. How can we approach for the same thing?

    Concerning

    Sree

    Hi Mary,

    Using formValue for the validation of the LOV? If Yes, then I guess that's the problem.

    If not, try setting the property to disable the LOV Validation point. This will disable your LOV validation. But in turn, you can check that your trim code works correctly. Recursive debug from here to share your results.

    Kind regards

  • Remove the left and right spaces with calculation

    I read in this forum that I can create a SQL expression calculation after 'Send' to remove the spaces to the left. I put in the source: ltrim(:P209_DESCRIPTION), but it did not work. You have another idea to achieve this? Thank you.

    Let us first find what you really use the following to replace all tabs with ' ~' and all the spaces with "%". This will give us a clearer picture of the characters that we have

    Select translate ('asd fd, chr (9) |) Chr (32),'~ %') of the double

    Then, we can use

    Select ltrim (: P209_DESCRIPTION, chr (9) |) Chr (32)) of the double

    for trim tabs and spaces

    Kind regards

  • Get rid of extra white space / margins on the left and right

    Hello. I have two problems.

    1.) when I create a model Muse to 1024 px wide, the document creates additional margins about 150-200 pixels to the left and to the right. No matter what I do, I can't get rid of this. I put both margins to "0". I need the site I created to be 100% width, no white space around.

    2.) my images are not importing correctly. When I place a picture, for example, my homepage background image, which is of size to 1024 px wide - identical to the width of the document, it does not matter to this size. Images are coming in about half the size, even though I'm positive, that the images are sized correctly, as I designed it in photoshop for the exact dimensions I wanted.

    Any help would be greatly appreciated!

    1.) muse generates no significant provision, so when you create a model Muse to 1024 px wide (centered on the assumption that in the browser), you end up with page 1024px wide and showing little space on each side to show you how the browser beyond 1024px screen would look like (where the browser window is wider than 1024px. It is not part of the width of the actual page. You can customize which using the browser option fill in the Control Strip.

    (2.) it appears you have the expected resolution HiDPI (2 x) in file > Site Properties > content tab. It would actually use the original size of the images on the screens of the retina and half in two dimensions on normal screens.

    Hope that helps.

    See you soon,.

  • Director of Windows capture only in black and white no color

    while trying to capture video from the color, it captures only in black and white

    Does not appear to be a 500 GB hard drive, but it can be
    a partition that uses a part of the training. In any case...
    you have enough free space and that's what I was afraid

    I think it may be interesting to try to update your video driver.
    There is a recent version (18/01/2011) for your Nvidia Geforce

    (do not forget to consult the list of "supported products" to check that)

    A way to check the make and model of your video
    adapter is to launch the Device Manager by clicking on...

    Start/run and type or copy / paste:

    devmgmt.msc

    And then press ENTER.

    Expand "Graphics cards" by left clicking the +.

    Right-click on the name of your card and choose...

    Click to install. There is some info to install it at the following
    link:

    If you decide to try it... maybe... I mean just maybe you

  • InDesign CC 2015 making the vertical border full length on the left and right of the epub

    Hello

    I'm working on a fluid epub 3.0 and I do the vertical borders to the left and to the right of the text. I created two object styles - one for left and one for the right border. These are vector shapes InDesign so I put in place of style to rasterize export options each and float in left (or right) accordingly. Both custom to an empty paragraph containing a nonbreaking at the top of the document, set automatic leading space anchor use. The problem, it's the ePUB to honor only the property float, based where the form is embedded. How can I get every border to sit to the left and right and still running the vertical length full of display area? I know that I could remove the forms and put in a shot of color on the text block, but this will put the borders on the top and bottom and sides. I would then have to crack open the ePUB and edit the CSS to limit borders on the left and right. I try to avoid cracks, it opens, but I'll do it if there is no other choice. Here is a screenshot of what it looks like to the InD and the other is a preview into Digital Editions (double page view).

    Well, I found this one on my own. I just got an external stylesheet and referenced when I export to ePUB. The style sheet has the css I needed and it works now!

  • Firefox 27.0.1 w/Mac OS 10.9.2 prints only half left of the Web page (any page).

    I used to be able to print correctly. Computer did some updates yesterday and now I have problems printing. Only the left part of the page prints.
    -J' checked the settings
    -J' I reset the print_ in all: config
    -J' changed the default font

    If Firefox does not use the entire page, it usually indicates a problem with getting the correct paper of the system size.

    When you reset the print settings in topic: config, reset it those related to the size of the paper?

    I do not know how you check the paper size to the printer by default on Mac, but that would be worth a glance.
