Javascript用模式分割字符串

Question

String:

Q$: any character, number goes here.
A$: Answer goes here
C$: c,c1,c2,c3

I want the final output as follows

  [Q$:=any character, number goes here.,
   A$:=Answer goes here,
   C$:=c,c1,c2,c3
  ]

If there are more than one string, then array should have all the values.

Eg:

String:

Q$: any character, number goes here.
A$: Answer goes here
C$: c,c1,c2,c3

Q$: any character, number goes here.A$: Answer goes here
C$: c,c1,c2,c3

Q$: any character, number goes here.    A$: Answer goes here

Q$: any character, number goes here.
A$: Answer goes here
C$: c,c1,c2

Final array should have all the items as an array to validate.

I have tried

 $(function() { var y = Array(); str = `Q$:ADD A GOOD QUESTION A$:ANSWER C$:choice0, choice1, choice2, choice2`; str.replace(/([ACQ]\\$:[\\S]*)(.*)/gmi, function(match, p1, p2) { y.push([p1, p2]); }); console.log(y); });

I am missing something. It works in few cases. In few it doesn't. Any suggestions to split them out.

What I have understood, as per your requirement, and assuming your output as a valid JSON object, Assuming order of Q$,A$,C$ will be always same, try this code

var str = "Your String"
//Add LineBreaks for making a valid format to make our search easier
var formattedOutput = str.replace(/[ACQ]\$/gm, function($0) {
    return "\n" + $0
})

//Split with all LineBreaks
var arr = formattedOutput.trim().split(/\n+/)

var res = [];
for(var i=0;i<arr.length;i++) {
    if(arr[i].indexOf("Q$") != -1) {
        res.push({
            "Q$":arr[i].trim().split(/Q\$:\s+/)[1]
        })
    } else {
        if(arr[i].indexOf("A$") != -1) {
console.log(arr[i].trim().split(/A\$:\s+/))
            res[res.length-1]["A$"] = arr[i].trim().split(/A\$:\s+/)[1]
        } else if(arr[i].indexOf("C$") != -1) {
            res[res.length-1]["C$"] = arr[i].trim().split(/C\$:\s+/)[1]
        }
    }
}
console.log(res)

 var str = $("#test").val() //Add LineBreaks for making a valid format to make our search easier var formattedOutput = str.replace(/[ACQ]\\$/gm, function($0) { return "\\n" + $0 }) //Split with all LineBreaks var arr = formattedOutput.trim().split(/\\n+/) var res = []; for(var i=0;i<arr.length;i++) { if(arr[i].indexOf("Q$") != -1) { res.push({ "Q$":arr[i].trim().split(/Q\\$:\\s+/)[1] }) } else { if(arr[i].indexOf("A$") != -1) { res[res.length-1]["A$"] = arr[i].trim().split(/A\\$:\\s+/)[1] } else if(arr[i].indexOf("C$") != -1) { res[res.length-1]["C$"] = arr[i].trim().split(/C\\$:\\s+/)[1] } } } $("#output").html(JSON.stringify(res))
