[jquery] How to prevent a double-click using jQuery?

I have the similar issue. You can use setTimeout() to avoid the double-click.

//some codes here above after the click then disable it

// also check here if there's an attribute disabled

// if there's an attribute disabled in the btn tag then // return. Convert that into js.

$('#btn1').prop("disabled", true);

setTimeout(function(){
    $('#btn1').prop("disabled", false);
}, 300);
