Forms and their child elements should not use input names or ids that conflict with properties of a form, such as submit, length, or method. Name conflicts can cause confusing failures. For a complete list of rules and to check your markup for these problems, see DOMLint.——jquery API
表单和其子元素不能用一个表单的属性作为name或id的名称，如submit, length, or method，会产生冲突。从而导致表单提交失败。Chorme中报错：Uncaught TypeError: object is not a function
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <script type="text/javascript"> function formSubmit() { document.getElementById("myForm").submit(); } </script> </head> <body> <form id="myForm" action="http://www.baidu.com" method="get" > 姓名：<input type="text" name="name" size="20"><br /> <input type="button" onclick="formSubmit()" name="submit" id="submit" value="提交"> </form> </body> </html>
用type="submit"方法不影响。
