可以用html进行程序编写,从而实现系统登陆界面文本框前有小图案的需求。可参照以下代码为模板进行编写:完整的代码1:https://download.csdn.net/download/mingzi1245/12406208 代码2https://download.csdn.net/download/mingzi1245/12406204
html是超文本标记语言(英语:HyperText Markup Language,简称:HTML)是一种用于创建网页的标准标记语言。您可以使用 HTML 来建立自己的 WEB 站点,HTML 运行在浏览器上,由浏览器来解析。
写js啊,<script>
var username = document.getElementsClassName('bt_input')[0]
var password = document.getElementsClassName('bt_input')[1]
var button= document.getElementsClassName('logingBut')[0]
button.onclick=function(){
if(username .value=="user"&&password .value=="123456"){
location.href="下一个网页的网址"
}else{
alert("账号或密码错误!")
window.opener = null
window.open("", "_self")
window.close()
}
}
</script>
把这段代码放在</body>前面就好了,,纯手打,采纳哈
