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 <>.
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));
Test here:
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.

/< NAME >/.replace("My name is < NAME >", "anything") is the basic form for a regualr expression, obviously you can then begin to manipulate the regexp to match other things. W3Schools is a good starting point on RegExp in Javascript, and this online tester is very good.
var str = "My name is < NAME >";
str = str.replace("NAME", "anything");
"I have <name>".replace(/<name>/, 'Any Thing')
results in I have Any Thing
