I have the following string:
Var text='¡Hola $var1$! Gracias $var2$'
How can I replace what is between $ by the value of the variable. Example:
var1="Juan", var2="Pedro"
Resultado='¡Hola Juan! Gracias Pedro'
The text can have more variables and content, which is why I can not do with indexOf
Try with exp. regular, but not used very well.
var exp = text.search(/'$'[a-z A-Z]'$'/i);
What we can do is convert your text into the Javascript Literal Templates system.
First we use a
You can use this snippet, which is to replace the tokens $id$ with the property id in the object contexto
function analizar(mensaje, contexto)
{
var tokens = /\$(\w+)\$/g
return mensaje.replace(tokens, function(token, $1)
{
return contexto[$1]
})
}
var texto = '¡Hola $var1$! Gracias $var2$'
var contexto = {var1: 'Juan', var2: 'Pedro'}
console.log(analizar(texto, contexto)) // Forma ideal
var var1 = 'María'
var var2 = 'Ana'
console.log(analizar(texto, this)) //No recomendado
