HTML防止input回车提交表单

作者:admin      时间:2016-10-14 13:28:18

最近在做一个小需求时,发现了一个问题:当form表单中,存在一个button,在input中按回车会自动触发form提交,很是郁闷,经过查询资料,特总结如下:


自动提交情况说明:

1.默认情况下,单个输入框,无论按钮的type="submit"还是type="button"类型,回车即提交。
2.当type="submit"时,无论有几个type="text"输入框,回车均表示提交。(按钮默认的type为submit)
3.当type="button"时,且存在多个输入框,回车不提交。(button)

解决方案:
1.解决单个输入框的回车即提交问题,可以增加一个隐藏的input="text" display='none'; 然后type类型为button。
2.在form表单或input中加入:onkeydown="if(event.keyCode==13){return false;}"
