单击按钮后如何显示弹出确认

Question

I'm still a learner on PHP.

I have a button, and it shall run a JavaScript after clicking it, but I want it to show an alert / pop up for users to confirm whether to continue or to abort.

Can I do the function in my PHP file in the button code?

<TD style='text-align:left;padding:0;margin:0;'>
    <INPUT type='button' onmouseup="javascript:JS1();" value='JS1'></INPUT>
</TD>

Answer 1

you need to make function and use confirm();

<TD style='text-align:left;padding:0;margin:0;'>
            <INPUT type='button' onmouseup="myFunction();" value='JS1'></INPUT>
        </TD>

And

<script>
function myFunction() {
    confirm("Please confrim");
}
</script>
