Question

If the form is clicked too quickly, it will be submitted multiple times. Is it necessary to add a mask layer to prevent multiple submissions?

Answer 1

<button type="button" class="layui-btn " id="sendSmsBtn" onclick="save()">Save</button>

Write ## in the JS method

#After click

$('#sendSmsBtn').addClass("layui-btn-disabled").attr("disabled",true);

After callback

$('#sendSmsBtn').removeClass("layui-btn-disabled").attr("disabled",false);
