Interval in JavaScript

Java­Script allows you to call a script on a regu­lar basis. The set­In­ter­val func­tion is available for this pur­po­se.

To create an interval in JavaScript with setInterval #

setInterval(function(){ 
     console.log("Ich werde jede Sekunde aufgerufen."); 
}, 1000);

Alter­na­tively, you can of cour­se pass func­tions ins­tead of using inline code.

function debugHello(){
    console.log("Ich werde jede Sekunde aufgerufen.");
}

setInterval(debugHello, 1000);

To remove/stop an interval after you have set it #

Of cour­se you can stop an inter­val at any time, for this you can use clear­In­ter­val.

var myInterval = setInterval(function(){ 
      console.log("Ich werde jede Sekunde aufgerufen."); 
}, 1000);

clearInterval(myInterval);

To extend the interval by parameters #

Fur­ther­mo­re, the who­le thing can also be exten­ded with para­me­ters:

var myInterval = setInterval(function(seconds){ 
       console.log("Ich werde jede "+seconds+" Sekunde aufgerufen");
}, 1000, "1");

Other para­me­ters can be added in the same sche­me.
