使用JavaScript用分号和逗号循环文本

Question

I have the following code:

var s=Stop;5,Service;13,Error;21,LINK DOWN;53,Data Incomplete;2,Replication Off;0,LINK DOWN;53

I need to loop in and get:

stop 5
Service 13
Error 21
.
.

I need to use an array because I have to get the value of stop service to show it on my html.

I have tried this:

var rslt = [];
for (var i = 0; i < 5; i++) {
  rslt[i] = s.substr(i, s.indexOf(','));
}

But it does not give me what I want.

Answer 1

Simply use split method with , as the argument. You don't need any loop for this.

 const arr = 'Stop;5,Service;13,Error;21,LINK DOWN;53,Data Incomplete;2,Replication Off;0,LINK DOWN;53'.split(','); console.log(arr); 

And if you want to get rid of those semicolons as well then you can do this.

 const arr = 'Stop;5,Service;13,Error;21,LINK DOWN;53,Data Incomplete;2,Replication Off;0,LINK DOWN;53' .split(',') .map(item => item.replace(';', ' ')); console.log(arr); 

Answer 2

You could split by comma and map the splitted values with semicolon.

 var s = 'Stop;5,Service;13,Error;21,LINK DOWN;53,Data Incomplete;2,Replication Off;0,LINK DOWN;53', values = s.split(',').map(t => t.split(';')); console.log(values); 

 .as-console-wrapper { max-height: 100% !important; top: 0; } 

Answer 3

Try with replace() and split() :

 var s='Stop;5,Service;13,Error;21,LINK DOWN;53,Data Incomplete;2,Replication Off;0,LINK DOWN;53' s = s.replace(/;/g,' ').split(','); console.log(s); 

OR: If you want make with nested array:

 var s='Stop;5,Service;13,Error;21,LINK DOWN;53,Data Incomplete;2,Replication Off;0,LINK DOWN;53' s = s.replace(/;/g,' ').split(',').map(i=> i.split(' ')); console.log(s); 

Answer 4

Simply replace the ; by a space. Then split your string into an array as following :

var temp = s.replace(";", " ").split(",");

NB : Your variable s is not well declared. Perhaps have I misunderstood the format of your "text".
