Struts2中javascrpit实现form的提交二-白红宇

Struts2剔除了Struts中对于form的应用，而action（Strus2）的action则综合了action，和actionForm的应用。但很多的应用中，都需要对输入进行验证，Struts中是将输入给表单，然后取得表单数据进行验证。虽然Struts2中取消了form的应用，这种方式还可以通过灵活地转化来继续使用。下面是两个例子，原理是相同的。因为博文8万字符限制，两个例子分开写。

例二

SCRIPT

type

"text/javascript"

function

addsave()

{

var

name = document.getElementById(

'subject'

).value.trim();

// var depName = document.getElementById('depName').value.trim();

(name.length==0)

{

alert(

讲话主题不能为空或者为空格！

)

return false

;

}

(name.length!=0)

{

(name.length<6||name.length>30)

{

alert(

讲话主题的长度在

至

之间！

)

return false

;

}

var

url=

"<c:out value='${cpath}'/>/information/speakaddSaveAction.action"

document.Form.action=url;

document.Form.method=

"post"

;

document.Form.enctype=

"multipart/form-data"

document.Form.submit();

}

function

back()

{

var

url=

"<c:out value='${cpath}'/>/information/speaklistAction.action"

document.Form.action=url;

document.Form.method=

"post"

;

document.Form.submit();

}
