表单基础：
可以通过document.form 集合来引用表单，例如：
document.forms[”myForm“]
其中html部分为：
<form method="post" name="myForm" action="addInfo.aspx">
基本的表单元素：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <title>Form Example</title> </head> <body> <form method="post" name="myForm1" action="addInfo.aspx"> <p><label for="name">请输入您的姓名:</label><br><input type="text" name="name" id="name"></p> <p><label for="passwd">请输入您的密码:</label><br><input type="password" name="passwd" id="passwd"></p> <p><label for="color">请选择你最喜欢的颜色:</label><br> <select name="color" id="color"> <option value="red">红</option> <option value="green">绿</option> <option value="blue">蓝</option> <option value="yellow">黄</option> <option value="cyan">青</option> <option value="purple">紫</option> </select></p> <p>请选择你的性别:<br> <input type="radio" name="sex" id="male" value="male"><label for="male">男</label><br> <input type="radio" name="sex" id="female" value="female"><label for="female">女</label></p> <p>你喜欢做些什么:<br> <input type="checkbox" name="hobby" id="book" value="book"><label for="book">看书</label> <input type="checkbox" name="hobby" id="net" value="net"><label for="net">上网</label> <input type="checkbox" name="hobby" id="sleep" value="sleep"><label for="sleep">睡觉</label></p> <p><label for="comments">我要留言:</label><br><textarea name="comments" id="comments" cols="30" rows="4"></textarea></p> <p><input type="submit" name="btnSubmit" id="btnSubmit" value="Submit"> <input type="reset" name="btnReset" id="btnReset" value="Reset"></p> </form> </body> </html>
文本框：
控制字符个数：
单行文本框的maxlength属性
textarea
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <title>控制textarea的字符个数</title> <style> <!-- form{ padding:0px; margin:0px; font:14px Arial; } input.txt{ /* 文本框单独设置 */ border: 1px inset #00008B; background-color: #ADD8E6; } input.btn{ /* 按钮单独设置 */ color: #00008B; background-color: #ADD8E6; border: 1px outset #00008B; padding: 1px 2px 1px 2px; } --> </style> <script language="javascript"> function LessThan(oTextArea){ //返回文本框字符个数是否符号要求的boolean值 return oTextArea.value.length < oTextArea.getAttribute("maxlength"); } </script> </head> <body> <form method="post" name="myForm1" action="addInfo.aspx"> <p><label for="name">请输入您的姓名:</label> <input type="text" name="name" id="name" class="txt" value="姓名" maxlength="10"></p> <p><label for="comments">我要留言:</label><br> <textarea name="comments" id="comments" cols="40" rows="4" maxlength="50" onkeypress="return LessThan(this);"></textarea></p> <p><input type="submit" name="btnSubmit" id="btnSubmit" value="Submit" class="btn"> <input type="reset" name="btnReset" id="btnReset" value="Reset" class="btn"></p> </form> </body> </html>
自动选择文本：
鼠标经过时自动聚焦，并选中删除默认值
