How can i set the onclick property for an element like link or button when it's created with Javascript or how can i set an eventListener?
I create the Button with JavaScript, set an Id and add a Class.
var button=document.createElement('button')
button.className="btn btn-sm btn-danger listening_class_for_delete"
button.appendChild(delete_text_button)
button.setAttribute('id',id);
// how can i set 'onclick' here
// output shall be:
<button ... onClick="functionName"></button>
I think this should make it:
document.getElementById(id).onclick = function() { }
you can add an onclick function to your button element like so:
1.
button.onclick = () => {
alert("onclick 1!");
};
button.addEventListener("click", ()=>{alert("onclick 2!")}, false);
Since you are using javascript you can add the onclick event listener directly to your script:
button.addEventListener('click', functionName);
If it is important for you to have it in the tag you can do the following with javascript:
document.querySelector('#button').setAttribute('onclick', 'functionName');
