Need to extract values from string in Javascript between words and characters

Question

I will be receiving the following string format from an AJAX call: [link= https://www.w3schools.com text=here]

I need to extract the values after "link=" and the value after "text=" so, my ideal output would assign " https://www.w3schools.com " to a variable and then "here" to a variable as shown in the code below. The values for "link=" and "text=" will change.

I've tried playing around with regex matching and using .split in Javascript, but I can't get the intended values just right.

var str = "[link=https://www.w3schools.com text=here]";
var link = str.match(/link=(.*)/)[1]; //gets the link but includes rest of string      
var linkText = str.match(/text=(.*)/)[1]; //gets "here" plus the closing bracket

Answer 1

add "\\s" and "]" in your pattern, Try this

 var str = "[link=https://www.w3schools.com text=here]"; var link = str.match(/link=(.*)\\s/)[1]; //gets the link but includes rest of string var linkText = str.match(/text=(.*)]/)[1]; console.log(link); console.log(linkText); 

Answer 2

You may use

 var str = "[link=https://www.w3schools.com text=here]"; var m, res=[], rx=/(?:^|[\\s[])(link|text)=([^\\][\\s]*)/g; while (m = rx.exec(str)) { console.log(m[1], "=", m[2]); } 

The regex is

/(?:^|[\s[])(link|text)=([^\][\s]*)/

See the regex demo .

Details

• (?:^|[\\s[]) - start of string or a whitespace or [
• (link|text) - Group 1: link or text words
• = - a = symbol
• ([^\\][\\s]*) - Group 2: any 0+ chars other than [ , ] and whitespace.
