How to confirm and call function with onclick

问题

Can I call JavaScript function with return confirm(); in HTML onclick event or do I need to do function which contains confirmation and call to another function?

<button onclick="return confirm('Are you sure?'); saveandsubmit(event);"></button>

Thanks in advance.

回答1:

Add if condition

<button onclick="if(confirm('Are you sure?')) saveandsubmit(event);"></button>

OR

<button onclick="return confirm('Are you sure?')?saveandsubmit(event):'';"></button>

回答2:

Try below :

<button onclick="confirm('Are you sure ?') && saveAndSubmit(event)">Button</button>


function saveAndSubmit(event){
    alert('saveAndSubmit called !');
}
