Issues with the split() function in JavaScript causing it to malfunction

I'm attempting to separate a string into different parts:

var str = "*HQ,6170930129,V1,185409,A,3132.3228,N,07424.7726,E,000.04,000,280618,FBFFBBFF,410,04,08028,40555#*HQ,6170930129,V1,185413,A,3132.3226,N,07424.7735,E,000.15,000,280618,FBFFBBFF,410,04,08028,40555"

var res = device_data.split('*');

However, this code isn't functioning as expected. It just presents the original string.

  var str = "*HQ,6170930129,V1,185409,A,3132.3228,N,07424.7726,E,000.04,000,280618,FBFFBBFF,410,04,08028,40555#*HQ,6170930129,V1,185413,A,3132.3226,N,07424.7735,E,000.15,000,280618,FBFFBBFF,410,04,08028,40555"

  var res = str.split('*'); 

  console.dir(res)

,HQ,6170930129,V1,185409,A,3132.3228,N,07424.7726,E,000.04,000,280618,FBFFBBFF,410,04,08028,40555#,HQ,6170930129,V1,185413,A,3132.3226,N,07424.7735,E,000.15,000,280618,FBFFBBFF,410,04,08028,40555

Instead of achieving an array with two distinct elements.

Answer 1

Answer №1

In my humble opinion, the code you're looking for might resemble the following:

let message = "*HQ,6170930129,V1,185409,A,3132.3228,N,07424.7726,E,000.04,000,280618,FBFFBBFF,410,04,08028,40555#*HQ,6170930129,V1,185413,A,3132.3226,N,07424.7735,E,000.15,000,280618,FBFFBBFF,410,04,08028,40555"

let splitMessageArr = message.split('*').filter(item => item !== "")

console.log(splitMessageArr)
console.log(splitMessageArr[0])
console.log(splitMessageArr[1])

let splitMessageArr = message.split('*').filter(item => item !== "")

console.log(splitMessageArr)
console.log(splitMessageArr[0])
console.log(splitMessageArr[1])

When you receive a string with a period at the beginning, it's because the process you're following ends up turning the result of String#split into a string. String#split actually gives back an array. When an array is converted to a string, it takes on the form of element0,element1,element2 ... elements separated by commas.

In this particular scenario, the outcome of String#split is ["",...] with 3 elements due to the initial character being '*', which gets treated as an empty string in the resulting array. So essentially, the result aligns with expectations and String#split is functioning correctly.

If you want to remove that first character from the string,

mystring.substr(1).split('*')

To eliminate any empty strings,

mystring.split('*').filter(s=>s!='')

This will give you the desired output.
