well obviously not simple to me but I’m sure it’ll be a piece of cake to some of you. I’m trying to concatenate some segments of an HL7 message but not really getting anywhere, this is the message:

NTE|1|T| Hi|
NTE|2|T| this|
NTE|3|T| is|
NTE|4|T| really|
NTE|5|T| annoying|
NTE|6|T| me|

the code I have is this but not doing anything:

var strFinalNTE = ”;

for each (seg in msg.NTE)
{
strFinalNTE = strFinalNTE + seg [‘NTE.3’][‘NTE.3.1’].toString();
}

Any ideas?

Should be pretty simple. What’s the format of the input message – a multiple-line string, or something else? An example of your expected result in strFinalNTE would be helpful also!

Hard (for me) to say without knowing a bit more about the HL7 message structure – I’m not sure if the structure you have sketched matches the structure you are iterating through

Here are some examples of iterating through an object/data structure from Stack Overflow

How to Loop through JavaScript object literal with objects as members?

Iterate through object properties

I think that the first may help you

is this in a broswer, what error’s it’s throwing? I assume you knowit should be “forEach”.

There’s quite a few things in there that aren’t right.

Anyhow, assuming no preprocessing and the msg is just a multi-line string:

var msg = “NTE|1|T| Hi|\n”
+”NTE|2|T| this|\n”
+”NTE|3|T| is|\n”
+”NTE|4|T| really|\n”
+”NTE|5|T| annoying|\n”
+”NTE|6|T| me|”;

var strFinalNTE = ”;

var msgSplit = msg.split(“\n”);
msgSplit.forEach(
function append(value) {
strFinalNTE += value.split(“|”)[3].toString();

}
)

alert(strFinalNTE);

Got bored whilst on phone to marketing man…

If you’re doing this regularly then…

String.prototype.HlCodeToArray = function (){
var output = [];
var msgSplit = this.split(“\n”);
output = msgSplit.map(function(value) {
return value.split(“|”);
});
return output;
};

var msg = “NTE|1|T| Hi|\n”
+”NTE|2|T| this|\n”
+”NTE|3|T| is|\n”
+”NTE|4|T| really|\n”
+”NTE|5|T| annoying|\n”
+”NTE|6|T| me|”;

var strFinalNTE = ”;

var msgArray = msg.HlCodeToArray();
msgArray.forEach(
function(value) {
strFinalNTE += value[3].toString();

}
);

document.getElementById(‘output’).innerHTML = strFinalNTE;

Cheers guys managed to work it out plus delete the old ‘fields’ so it just comes through as the one message. Don’t do this a lot hence the daft question.
