1、设计源码 复制代码代码如下: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Form提交表单页面不跳转</title> </head> <body> <form action="" id="" method="post" target="id_iframe"> <input type="text" id="input_text" name="input_text"/> <input type="submit" id="sobmit" name="submit" value="提交" /> </form> <iframe id="id_iframe" name="id_iframe"></iframe> </body> </html> 2、运行结果 (1)输入“451”,单击“提交” (2)输入“45464646”,单击“提交” 页面提交刷新,不跳转
