见代码:
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>表单对象--获取表单值的7种方式</title> </head> <body> <form action="" name="myform"> <input type="text" name="user" value="admin"> </form> <script> document.write(document.myform.user.value+"1<br/>"); document.write(document[‘myform‘].user.value+"2<br/>"); document.write(document.forms.myform.user.value+"3<br/>"); document.write(document.forms[0].user.value+"5<br/>"); document.write(document.forms[‘myform‘].user.value+"4<br/>"); document.write(document.forms.item(0).user.value+"6<br/>"); document.write(document.forms.item(‘myform‘).user.value+"7<br/>");//FF可能不支持 </script> </body> </html>
推荐使用
document.write(document.myform.user.value);
