I have a list like this :
[EMP004: BPCE-RNHC-25G8, EMP003: 8FIW-9JRB-NY4J, EMP005: 7QF2-6HI9-XKZZ, EMP002: SG8P-YQKG-ZV3C, EMP001: PBF7-WZHT-WPZR]
What I trying to achieve:
User input the first key and then the system will scan through the list and show them corresponding key. For example, if user input "EMP004", it should alert BPCE-RNHC-25G8 for them.
Idea:
How can I separate the first key and second key with : ? Other than that how can I know find the corresponding result? Does anyone know how can i solve this with JavaScript only ? Thanks in advance.
The sample list you have provided is syntactically incorrect. You can create an array object. Then you can create function that takes the key as the parameter like the following way:
const list = [
{ EMP004: 'BPCE-RNHC-25G8' },
{ EMP003: '8FIW-9JRB-NY4J' },
{ EMP005: '7QF2-6HI9-XKZZ' },
{ EMP002: 'SG8P-YQKG-ZV3C' },
{ EMP001: 'PBF7-WZHT-WPZR' }
];
const getValByKey = (key) => Object.values(list.find(o => Object.keys(o)[0] === key ))[0];
console.log(getValByKey('EMP004'));
console.log(getValByKey('EMP002'));Update: For string items you can try the following way:
const list = ['EMP004: BPCE-RNHC-25G8', 'EMP003: 8FIW-9JRB-NY4J', 'EMP005: 7QF2-6HI9-XKZZ', 'EMP002: SG8P-YQKG-ZV3C', 'EMP001: PBF7-WZHT-WPZR'];
const getValByKey = (key) => list.find(item => item.split(':')[0].trim() === key ).split(':')[1].trim();
console.log(getValByKey('EMP004'));
console.log(getValByKey('EMP002'));You can do like this:
function search(arr, sub) {
sub = sub.toLowerCase();
matchedIndex = arr.map((str, index) => {
if (
str.toLowerCase().startsWith(sub.slice(0, Math.max(str.length - 1, 1)))
) {
return index;
}
});
if(matchedIndex.length>0){
console.log(matchedIndex);
matchedIndex = matchedIndex.filter(function( element ) {
return element !== undefined;
});
return matchedIndex[0]
}
}
var arr = ["EMP004: BPCE-RNHC-25G8", "EMP003: 8FIW-9JRB-NY4J", "EMP005: 7QF2-6HI9-XKZZ", "EMP002: SG8P-YQKG-ZV3C", "EMP001: PBF7-WZHT-WPZR"];
var index = search(arr, 'EMP004');
if(index>-1){
matchedvalue=arr[index].split(':');
console.log(matchedvalue[1]);
}
else{
console.log("Not found")
}
