How do I get the text between two characters of a string in JavaScript?

I have an array like this:

var people = [
    '<option value=\'64\'>Tom',
    '<option value=\'76\'>Dan',
];

I am looping through each item in the array to extract the value (like the number 64 in the first item) and the text (like Tom in the first item). I tried multiple ways of extracting these details from each item but I am unable to. I even tried using substrings and other methods. Can someone tell me how to extract this information?

You should use a regular expression in such a case.

For example:

var things = people.map(function(s){
  return s.match(/(\d+)\W+(\w+)$/).slice(1)
});

This builds this array:

[ ["64", "Tom"], ["76", "Dan"] ]

You might want to adapt it for your precise needs:

  • check an array is returned by match, if some strings might be invalid
  • change the regex if the pattern is more variable

Note that you probably shouldn't have such an array to start with. If you generate it server-side, you should opt for the generation of a JSON structure instead and let the client script build the interface from the data, instead of building it from something which is neither clean data nor GUI.

You can use multiple split :

var str = '<option value=\'64\'>Tom';

var tmpStr = str.split("'");

var number = (tmpStr[1].split("\\"))[0];

var name = (tmpStr[2].split(">"))[1];

document.write(number + " " + name);
