Answer 1

form标签才有submit()方法，所以会出现submit is not a function可以这样试试看<input type="image" src="图片路径"> type="image"默认是submit行为的了也可以<button type="submit"><img src="...."></button>submit()行为要对form标签<form id="f1">...........<button type="submit"><img src="..."></button></form><button type="button" id="btn1"><img src="..."></button>以上点button是默认提交的了，不要再写js了，若是form外点就要下面这样写var btn1 = document.getElementById("btn1");btn1.addEventListener('click',function () {document.getElementById("f1").submit();},false);
