js限制按钮每隔一段时间才能再次点击
设置属性 disabled 可以限制交互，单击按钮时添加disabled=“disabled”属性，再为按钮添加定时器，一定时间后删除定时器和disabled属性

或者用DOM
1 <script> 2 var but = document.getElementById('but'); 3 but.addEventListener('click', function() { 4 var id = 10; 5 var attr = document.createAttribute("disabled"); 6 attr.nodeValue = "disabled"; 7 //设置节点属性 8 but.attributes.setNamedItem(attr); 9 var timeing = setInterval(function() { 10 id = id - 1; 11 but.innerHTML = id + 's'; 12 }, 1000); 13 window.setTimeout(function() { 14 clearInterval(timeing); 15 but.innerHTML = '发送'; 16 //移除节点属性 17 but.attributes.removeNamedItem('disabled'); 18 }, 10000); 19 }); 20 </script>
