Sample Input :- (;1A;<1&&;2;<2&&;100Baxc02;<3&&;1000D33;<4&&;10001HGA;<5)
Expected output :- 1A,2,100Baxc02,1000D33,10001HGA
Note :- Length of input is not fixed it varies.
My code so far:
var AlertExpressionWithUid = "(;1A;<1&&;2;<2&&;100Baxc02;<3&&;1000D33;<4&&;10001HGA;<5)";
theArray = AlertExpressionWithUid.split(';');
output="";
for (i = 0; i < theArray.length; i++) {
theelm = theArray[i];
output = output + theelm;
}
alert(output);It looks like you want to match substrings between ;s which don't contain && - why not use a regular expression? Using lookbehind:
const AlertExpressionWithUid = "(;1A;<1&&;2;<2&&;100Baxc02;<3&&;1000D33;<4&&;10001HGA;<5)";
const matches = AlertExpressionWithUid.match(/(?<=;)[^;&]+(?=;)/g);
console.log(matches);Or, since lookbehind is supported only in newer browsers, without lookbehind, you'll have to use a loop instead:
const AlertExpressionWithUid = "(;1A;<1&&;2;<2&&;100Baxc02;<3&&;1000D33;<4&&;10001HGA;<5)";
const re = /;([^;&]+);/g;
let match;
const matches = [];
while ((match = re.exec(AlertExpressionWithUid)) !== null) {
matches.push(match[1]);
}
console.log(matches);
It seems that you need the values with odd index of splited array so use a condition in your for loop as i%2 !== 0. Since, you need
var AlertExpressionWithUid ="(;1A;<1&&;2;<2&&;100Baxc02;<3&&;1000D33;<4&&;10001HGA;<5)";
var output=[];
var theArray = AlertExpressionWithUid.split(';');
for (i=0;i<theArray.length;i++)
{
if(i%2 !== 0){
output.push(theArray[i]);
}
}
output = output.join(',');
console.log(output) ;You can also refactor your code to use Array.filter() like this:
var AlertExpressionWithUid ="(;1A;<1&&;2;<2&&;100Baxc02;<3&&;1000D33;<4&&;10001HGA;<5)";
var theArray = AlertExpressionWithUid.split(';');
var output = theArray.filter((item, index) => index%2 !==0 ).join(',');
console.log(output);Try this.
var AlertExpressionWithUid = "(;1A;<1&&;2;<2&&;100Baxc02;<3&&;1000D33;<4&&;10001HGA;<5)";
theArray = AlertExpressionWithUid.split(';');
var output='';
for (i = 1; i < theArray.length; i+=2) {
theelm = theArray[i];
output = output +','+ theelm;
}
console.log(output.slice(1));Assuming you cannot have < as a value, try this filter
var AlertExpressionWithUid = "(;1A;<1&&;2;<2&&;100Baxc02;<3&&;1000D33;<4&&;10001HGA;<5)",
res = AlertExpressionWithUid.split(";")
.filter(function(item) { return item.indexOf("<") ==-1 });
res.shift(); // drop the leading "("
console.log(res.join(","))var AlertExpressionWithUid = "(;1A;<1&&;2;<2&&;100Baxc02;<3&&;1000D33;<4&&;10001HGA;<5)";
AlertExpressionWithUid = AlertExpressionWithUid.substring(1, AlertExpressionWithUid.length-1);//remove "(" and ")"
theArray = AlertExpressionWithUid.split(';');
output="";
for (i = 0; i < theArray.length; i++) {
if (i%2!=0)
output = output + (output != '' ? ',' : '') + theArray[i];
}
alert(output);
