JavaScript, check if it is a number or a string?

• Check if there is a number to a string

  Hey guys,.

  If I had a '2 cats' string, how could use a tape Loop statement to check if there is a number in there

  I got this far:

  for (var i: Number = 0; i < string.length; i ++) {}

  If (Equation.charCodeAt (i) < = 57)

  {if (equation.charCodeAt (i) > = 48)}

  {trace ("Number")

  }

  }

  }

  It works, but is there a more effective to achieve AA?

  Any thoughts would be appreciated

  Thank you very much

  Chris

  You can also use exec() regexp method if you need to detect multiple instances. For example, this code:

  var string:String = "It is 12 o'clock 24 hours 365 days";
  var pattern:RegExp = /\d+/g;
  while (pattern.exec(string))
  {
      trace("exec", pattern.lastIndex);
  }
  

  Shows:

  Exec 8

  exec 19

  exec 29

  This means that the numbers are in positions 8, 19 and 29

• Fract/Exp Numbe display Format string

  I have a digital channel that has a decimal value with accuracy up to 16-digit figures. I want to convert this string to a numeric value, and I used a "Fract/Exp number necklace. In my VI I hae set:

  Data type: EXT (because it allows number of decimal digits of 15 to 20)
  Data format: covered Point
  Numbers: 16
  Precision Type: Digits of precision

  Here's my question: If the input string is composed of digits of precision = 15 Eg: 5.369607712106161
  Then I output = 5.3696077121061609, which is the same, but not the same number I sent.
  or 1.145152879691825 String gives me the number = 1.1451528796918251
  String 5.818356760119754 gives me the number = 5.8183567601197543

  Please suggest how I can make more specific output.

  Thank you.

  Kind regards

  Wire a constant to the default value with the entry of your string to the function of numbers and define the type of POSITION, it is default DBL (note the red dot on your meter).

• BlackBerry Z10 check what type of phone number an SMS is sent to

  It doesn't seem to be any way to check which number an SMS has been sent to. Is this fair?  Does that take back me to the entrance, where I can have more than one option by phone.  Seems strange.

  It's true, and I hope that BlackBerry is aware and will be fixed.

• Problem with the installation of CS3. The update check does not accept serial number

  Hey,.

  I have CS3 I need to install one Mac to another. It has already been turned off and installed again as well. But after entering the serial number, I can see window called Updade check and here my series does not work. Technical support can't not old versions, so that they cannot help me. But I have to run CS3 on the mac anyway. Can I skip step of checking the update anyway? Or what I can do to run this? Problem is that I already can't even use it on a previous machine because it has been disabled.

  Does anyone know what should I do in this situation?

  ignore the update checking.

  You can update each program directly after installation and activation, if you need.

• How check and rounding a whole number?

  Newbie question:
  
  How can I check a given integer (and not int) to see if there are round and next round.
  
  for example
  If the integer is 3456 - do nothing.
  
  If the integer is 3456.9 - round until 3456
  
  Thank you!

  This is the behavior of the integers already. If you assign a number to floating point to integer (int or integer) it truncates the fraction part.

• check if the qstring is number

  How can I DO?

  ... but to answer your actual question, you can actually use the return value to check...

  QString s = "your text here";
  
  bool isNum;
  
  int value = s.toInt(&isNum);
  
  if (isNum)
     // use returned value
  else
     // report error
  

  Not tested, but should work.

• JavaScript - Check if the property value is substituted

  Hello people,

  Does anyone know how to check if a property definition for a given node has been replaced? Here is some information about what we are trying to accomplish.

  We have descriptions in Core.Descr, which are all in English.

  We have a property called Custom.DESCR.Chinese RWDerived that points to the description in English. If the value is changed, it means that a Chinese description has been entered.

  I need to develop the script for a property which will focus on property above (Custom.DESCR.Chinese). If the value has not been replaced, this property should return "ENG". If the property has been overridden, this property should return "ZHO".

  That's what I've tried so far...

  var a = node. Prop ("Custom.Descr.Chinese"). GetPropDef();

  Print ("PropDef object =" + a); / / works, returns Custom.DESCR.Chinese

  Print ("Test: Level =" + a.Level); / / returns 0,

  Print ("Test: PropOrigin =" + a.PropOrigin); //undefined

  Print ("Test: PropType =" + a.PropType); / / works, returns 11

  Print ("Test: Descr =" + a.Descr); / / works, returns the Description of Chinese

  Print ("Test: PropClass =" + a.PropClass); / / works, returns the formula

  print ("Test: substitute =" + a.Overridden); //undefined

  Print ("Test: Abbrev =" + a.Abbrev); / / works, returns Custom.DESCR.Chinese

  Print ("Test: DataType =" + a.DataType); / / works, returns 11

  I can't access some of the properties of the PropertyDefinitionObject, but unfortunately, PropOrigin does not work, I think that is what is needed. I don't know if PropOrigin will not work in this context, or if there is something small miss me.

  Any help is appreciated!

  Thank you

  Jordan Wilcox

  Jordan

  The object must be an object of the Node.Prop with the GetPropDef() method to access the original property

  Try to use

  var a = node. Prop ("Custom.Descr.Chinese")

  Print ("Test: PropOrigin =" + a.Origin)

  This should give you 2 for the node whose value is overloaded.

  Thank you

• JavaScripts-check boxes do not return of eigenvalues

  Hi all, do not know if this is the right place for this post... but here goes...

  Here's the url:

  http://theexperience-Exchange.co.UK/Mods_appleit.html

  The contact form generates and electronic.  At the moment the results form the boxes look like this:

  $1_month

  $6_months

  $12_months

  You can see that they do not work... If only one is checked, they will appear! I know there are some html and JS needed... to the web search leads me around the bend.

  No simple solution that everyone knows would be greatly appreciated.

  All the best, RP

  Unless you want them to have the option to click 1, 2 or 3 of these boxes, it would be preferable to use a group of option buttons. In this way, can only be clicked and that the value of the button clicked will return to you.
