Below is an example of a String that I want to split it to 3 parts from a substring
test01String001s
Examples:
example_1 subString == "0"
res: [ "test","0","1String001s" ] - test01String001s
example_2 subString == "st"
res: [ "te","st","01String001s" ] - test01String001s
example_3 subString == "01s"
res: [ "test01String0","01s", "" ] - test01String001s
example_4 subString == "t"
res: [ "","t","est01String001s", ] - test01String001s
I try to resolve it via
var string='test01String001s'
var keyword="01"
console.log(string.split(keyword));
output:
["test","String0","s"] instead of [ "test","01","String001s"]
or
var string='test01String001s'
var keyword="0"
console.log(string .split(keyword, 2));
output
["test","1String"]
To get 3 parts I wouldn't use split, but use some logic
const mystring = 'test01String001s'
const sp = ['01','1','t','st', '1s']
sp.forEach(item=>{
let idx=mystring.indexOf(item)
let result=[]
if(idx===0){
result.push('')
result.push(item)
result.push(mystring.slice(item.length))
}else if (idx+item.length ==mystring.length){
result.push(mystring.slice(0,idx))
result.push(item)
result.push('')
}else if(idx!=-1){
result.push(mystring.slice(0,idx))
result.push(item)
result.push(mystring.slice(idx+item.length))
}
console.log(result)
})Try this.
var string = "test01String001s";
var splitKey = '01';
var components = string.split(splitKey);
var array = ([components.shift(), components.join(splitKey)]);
array.splice(1, 0, splitKey);
console.log(array.join());Output: test,01,String001s
This should work:
const test = 'test01String001s';
const key = "t";
const re = new RegExp('(.*?)(' + key + ')(.*)');
const result = test.match(re, "regex");
result.shift();
console.log(result);
So this regex match is returning an array of:
(.*?) - anything before key
(' + key + ') - key
(.*) - anything after key
Unfortunately it also returns the whole matched word, so I used shift to remove first match from array.
