Question

I have a problem to add the dynamic values to a string.

For example:

My name is < NAME >

Now I want to replace NAME with my name so my string will become:

My name is anything.

How I can achieve this?

The dynamic part will be always between <>.

Answer 1

var result = "My name is < NAME >".replace("< NAME >", "anything");

do you want this? Or are you searching for something more complex that enums all the words between < and >? Something like:

var matches = "My name is < NAME > < SURNAME >".match(/<[^>]+>/g);

If you want to replace multiple parts you could do this:

var replacer = function (str)  
{  
    if (str === '< NAME >')
    {
        return 'anything';
    }
    else
    {
        return 'nothing';
    }
};

var replaced = 'My name is < NAME > < SURNAME >'.replace(/<[^>]+>/g, replacer));

A more complete example:

var name = 'anything';
var surname = 'anyone';

var myInputText = "My name is < NAME > < SURNAME >";

var replaced = myInputText
    .replace(/<[^>]+>/g, 
        function (str)  
        {  
            if (str === '< NAME >')
            {
                return name;
            }
            else if (str === '< SURNAME >')
            {
                return surname;
            }
            else
            {
                return '***error***';
            }
        }
    );

I’m using javascript anonymous functions that “close” around the name and surname variables.
