I have the following simple code:
<input id="nick" type="text"/>
<script>
var c = document.getElementById('nick').value
</script>
I need to remove a part of the name, only if it has brackets [] .
So if you have this name: 'Hola soy juan [soy pro]' ,
it would look like this: 'Hola soy juan' .
An alternative is the use of replace in conjunction with the regular expression 1 /\[.+?]/g where:
\[ : escape the opening bracket. . : Any character + : One or more characters equal to the previous one ? : Stingy, the least number of times g : Global 1 By regular expression I am referring to a RegEx object. Just as the Array objects when declared using the short form,
[elemento1,elmento2], do not carry quotes, nor do the RegEx/expresionregular/banderasobjects carry it.
In the following code, two cases are included, one similar to that indicated by the OP and another a bit more complex.
//Caso simple, una sóla ocurrencia
var texto1 = "Conservar este texto [eliminar este] pero convervar esto otro";
//Caso complejo, varias ocurrencias no consecutivas
var texto2 = "manzana [melón] melocotón [membrillo] mora";
// Asignar la expresión regular propuesta a una variable
var re = /\[.+?]/g;
//Realizar la eliminación mediante reemplazar para los dos casos.
var salida1 = texto1.replace(re,'');
var salida2 = texto2.replace(re,'');
//Agregar el resultado a la página
document.write('Caso 1: ' + salida1 + '<br/>Caso 2: ' + salida2); You can use substr and replace in a loop to delete all texts that are within [ ]
For example, if you try 'Javier [the best] of [your home in] Panama' , the result will be Javier de Panama
Then we eliminate all repeated spaces with the code
output.replace(/\s+/g,' ').trim();
I hope you serve
var example = document.getElementById('example'),
result = document.getElementById('result');
example.addEventListener('keyup',function() {
var output = this.value,
finish = false;
while(!finish) {
if(output.indexOf('[') >=0 && output.indexOf(']') >= 0) {
output = output.replace(output.substr(output.indexOf('['), output.indexOf(']') - output.indexOf('[') + 1),'');
}
else {
finish = true;
}
}
result.innerText = output.replace(/\s+/g,' ').trim();
});<input type="text" id="example" />
<span id="result"></span>I've already done it if someone is interested:
var c = "Hola amigos [quiero que me eliminen]";
var d = c.split('');
var buscar1 = d.indexOf('[');
buscar1 = parseInt(buscar1);
var buscar2 = d.indexOf(']');
buscar2 = parseInt(buscar2);
var total = buscar2 - buscar1;
var eliminar = d.splice(buscar1, (total +1));
var g = d.join('');
document.write(g);
