I'm trying to do something very simple - adding two numbers. However instead of "adding" it's concatenated instead.

I have set my field to Whole Number (integer) and in my jscript code basically just add 1 

function check_version() {

 var request_doc_version = XDocument.DOM.selectSingleNode("my:document/my:metadata/my:doc_version"); 
 var request_doc_create_version = XDocument.DOM.selectSingleNode("my:document/my:metadata/my:doc_create_version");

 var doc_version = getInfo( 'version' );
 
 if ( request_doc_create_version.text == "Yes") {
   
  request_doc_version = doc_version + 1;
  
 } else {
    
  request_doc_version.text = doc_version;
  
 }
 
 return;
 
}

Don't quite understand.

Is there a way to conver the string to integer or number?

 Could you explain what the getInfo() function is doing?

 To convert a string to an int, you can use parseInt(var), but this line looks problematic:

request_doc_version = doc_version + 1;

because request_doc_version is an XML node, not a string variable. Try:

request_doc_version.text = parseInt(doc_version) + 1;

Oh sorry it should have been request_doc_version.text initially - pasted the wrong code

 However none of them work. For example...

  XDocument.UI.Alert(request_doc_version.text + 1); // returns 21
  XDocument.UI.Alert(parseInt(request_doc_version.text) + 1); // returns 1.#QNAN
  XDocument.UI.Alert(parseFloat(request_doc_version.text) + 1); // returns 1.#QNAN

Apparently you can do Convert.ToInt32 method in jscript... but I am not familar with this http://msdn.microsoft.com/en-us/library/system.convert.toint32(VS.71).aspx

Any other ideas? Thanks

Hi,

What is the value of ‘request_doc_version.text' here? Can you check once?

parseInt method works like this.

parseInt("abc")     // Returns NaN.

parseInt("12abc")   // Returns 12.

parseInt("12") // Returns 12.

Hope this helps.

I tried it again this morning it returned the right result from what I did previously. Strange.

 Thanks for the help.

However that was just my quick fixed.

 But what I really want is a convert a string to a number as for doc_version, the value is actually taken from a database which returns a number as a string.

I cannot use parseInt for this as it is a string and therefore returns 1.#NAN
