The onclick event occurs when the user clicks on an HTML element.
Use theaddEventListener()
method to attach a "click" event to a HTML element. You only need to replace you button id wth "someId"
document.getElementById("someId").addEventListener("click", function(){
if (this.value=="Some text") {
this.value = "other text";
}
else{
this.value = "Some text";
};
});
