Hello! How do I run a code within event listener programatically?
Example:
document.getElementById("voltar").addEventListener('click', function() {
alert("teste");
}, true);
I want to execute alert of addEventListener . I tried to set a name in function() , and call alerta_listener() but it did not work.
You can abstract the contents of this function, and create another by calling it at any time. Ex:
function Teste(){
alert("teste");
}
document.getElementById("voltar").addEventListener('click', function() {
Teste();
}, true);<button type="button" id="voltar">Voltar</button>Or, if you use JQuery, you can trigger the event using the trigger .
Ex: $(elemento).trigger("click");
You can run alert (or any other code within event listener ) by creating a trigger click() for the event:
document.getElementById("voltar").click();
document.getElementById("voltar").addEventListener('click', function() {
alert("teste");
}, true);
document.getElementById("voltar").click();<input type="button" value="Voltar" id="voltar" />You can also use a separate function:
function alerta(){
alert("teste");
}
document.getElementById("voltar").addEventListener('click', alerta, true);
function alerta(){
alert("teste");
}
document.getElementById("voltar").addEventListener('click', alerta, true);<button type="button" id="voltar">Voltar</button>
