How can I limit a text string with javascript or jquery ???
I have a data brought from the database, but that data is too long and I unravel my design, what I want is for example, if that data is greater than a certain number of characters co javascript or jquery put ".. . "substituting the rest of the paragraph, how can I do that?
Thanks in advance :)
You can do something like this:
var str = "Hello world!";
var res = str.substring(0, 2);
var final = res +"...";
console.log(final);
Try this:
function recortar(){
var logitud = 20;
var dato = "texto largo";
var datoAMostrar = "";
for(var i = 0; i < logitud; i++)
datoAMostrar = datoAMostrar + dato[i];
datoAMostrar = datoAMostrar + "...";
}
You must be careful because if the length (number of characters to show) is greater than the text, an undefined will appear. This would be arranged in the following way:
function recortar(){
var logitud = 20;
var dato = "texto largo";
var datoAMostrar = "";
for(var i = 0; i < logitud && i < dato.length; i++)
datoAMostrar = datoAMostrar + dato[i];
datoAMostrar = datoAMostrar + "...";
}
It is a solution similar to the previous ones, but maybe it is something shorter than the second, and more elaborate than the first one:
function recortaDatos(dato,longitud){
var respuesta = dato;
if(dato.length>longitud){
respuesta = dato.substring(0,longitud-3)+"...";
}
return respuesta;
}
Now, at the time of collecting the data, within the loop that I suppose you will create to iterate between those data, simply always pass the same data through this filter: (example)
for(var i =0; i<listado.length; i++){
for (var j = 0; j< listado[i].length; j++){
$(donde rellenes el dato).text(recortaDatos(listado[i][j]));
}
}
I hope it helps you.
